HOW TO USE THIS MANUAL
Your modem is supplied with its own Quick Reference Manual which provides
connection diagrams, basic application parameter settings using configuration
strings, default values, and specific technical features. You can see either your
modem's Quick Reference Manual or this manual for initial configuration.
Initial configuration must be performed through the RS232 interface.
To use this manual for initial setup see chapter 3.
If you need to change the default settings for your specific application, see chapter 4
and the Examples in appendix A.
DL Sm@rtSet
DL Sm@rtSet program, available on the installation CD-ROM, is a Windows-based
utility program providing a quick and user-friendly configuration method via RS232.
It allows defining the desired parameter values and sending the complete
configuration directly to the connected STARModem™ via serial interface.
In addition, it also transmits software upgrades to the connected device.
Sending Configuration Strings from Host
This configuration method may be used for initial and complete configuration by
sending the desired strings provided in Chapter 4 through the RS232 interface. Batch
files containing the desired parameter settings can be prepared to configure the
modem quickly and easily.
Reference notes describing the operation of more complex parameters are given in
chapter 5.
Reading Configuration Barcodes
This configuration method allows setting STARModem™ by reading configuration
barcodes with a Datalogic RF device and sending the commands to the modem via
radio.
Initial configuration cannot be performed using this method. However, this method is
particularly useful in changing configuration parameters of a STARModem™
working in Wedge or Pen Emulation interfaces (except radio parameters, which must
be configured in RS232).
All barcodes are provided in the “STARModem™ Configuration Using Barcodes”
document available on the CD-ROM.

INTRODUCTION
STARModem™ is a radio modem developed to provide wireless 433 MHz RF
(European models) / 910 MHz (USA model) communication between any serial
device (Host) and Datalogic RF devices or base stations, such as:
-
Gryphon™ M Readers
-
Dragon™ M Laser Scanners
-
STARModem™ Radio Modems
-
Formula Basic Line RF Terminals (F734-E/RF, F725-E/RF, F660-E/RF)*
-
STARGATE™ Base Stations
*
not compatible with STARModem™ USA model.
STARModem™ can be configured to communicate either in Stand Alone Mode
(see par. 2.1.1) or STAR-System™ mode (see par. 2.1.2).
1.1
LED INDICATORS
STARModem™ has three LEDs as displayed in the following figure:
Figure 1 - STARModem™ LED Side

DESCRIPTION
STARModem™ is powered.
STARModem™ is receiving or transmitting data.
STARModem™ is working correctly.
-
Red blinking
-
-
at startup, after firmware download, it indicates
that the system is working with default
configuration.
during normal functioning it signals a wrong
connection to the Host.
it blinks during a programming command
execution. In case of wrong command, it will
blink faster;
it blinks once when STARModem™ radio
transaction fails.
Software Upgrade
It is possible to upgrade the software of STARModem™ by using the DL Sm@rtSet
program or the Downloader program provided on the installation CD-ROM.
During this procedure the Power On LED is off while the TX/RX and Status LEDs
blink alternatively.
Once the software upgrade has been completed, the Status LED stays on and
STARModem™ starts working with its default configuration.
NOTE
The software upgrade can be performed only when the Frame
Packing parameter is set to “Frame + [CR]” value (see par. 5.2.5 for
details).
In case of software upgrade failure, follow the given steps:
1)
turn off STARModem™;
2)
connect STARModem™ to the Host;
3)
start the Downloader program until it asks for the device reset;
4)
turn on STARModem™.
The modem software will be upgraded successfully.

MOUNTING AND CONNECTIONS
2.1
BASIC SYSTEM LAYOUTS
There are two basic system layouts that can be employed: stand alone and
STAR-System™ (for other layouts refer to the examples given in appendix A).
2.1.1
Stand Alone Mode
In Stand Alone mode, STARModem™ can be setup in uni-directional
communication to either receive data via radio from Datalogic RF devices, or transmit
data via radio to Datalogic RF devices. Currently supported devices are RF
hand-held readers, another STARModem™ or RF terminals loading STAR&Play™
software (not compatible with STARModem™ USA model).
When receiving data, STARModem™ as a Server works like a Datalogic
OM-cradle (refer to STARModem™ 1 in the figure below); therefore, the received
data will only be sent to the connected Host.
Since STARModem™ functions as a cradle in this configuration, all the
multistandard interface selections are valid (RS232, Wedge, Pen Emulation).
STARModem™ in transmission (refer to STARModem™ 2 in the figure below) as
Client works like a data collection RF Device (ex. DRAGON™ M) transmitting the
collected data via radio to the destination Stand Alone device (STARModem™ or
cradle).
In Stand Alone mode, the system implements a different RF Narrow Band radio
protocol than STAR-System™.
NOTE
For communicating with STARModem™ in Stand Alone mode,
configure all Datalogic RF devices by using the commands of the
Stand Alone Mode procedure available in the “RF Device Setup For
STARModem™” document on the CD-ROM.

Figure 2 - Stand Alone Mode
To configure the modem for operating in this mode refer to par. 3.2.

STARModem™
2.1.2
STAR-System™ Mode
In STAR-System™ mode, STARModem™ uniquely provides a wireless
bi-directional communication between the Host and the RF devices.
STARModem™ 1 in the figure below is a Server (receiver) to the RF Devices and
also a Client (transmitter) to STARModem™ 2, which receives data for the printer.
This mode is only for RS232 communication.
STAR-System™ uses the Narrow Band RF radio and Datalogic CSMA/CA protocol
to automatically link and manage all the RF devices in the system. This protocol
manages the data transmission using a 16-bit CRC checksum. All RF devices in the
system must implement the CSMA/CA protocol and therefore be configured using
the STAR-System™ setup procedure (refer to STARModem™ and the RF devices
in the figure below).

INITIAL SETUP
For a correct STARModem™ configuration keep in mind the following guidelines:
•
when using the modem for the first time, set the desired STARModem™
address via RS232 serial interface, since its factory default address is
"Undefined";
•
for Wedge/Pen Emulation interface connections, set all parameters via RS232
interface either using DL Sm@rtSet or sending configuration strings to
STARModem™. Then, set the correct hardware jumper position as indicated in
the table given in par. 3.2.1 under "Interface Selection".
For changing any configuration parameter in Wedge/Pen Emulation interface
connections, send the new configuration commands via radio using Datalogic RF
devices (refer to “STARModem™ Configuration Using Barcodes” document
provided on the CD-ROM). Otherwise, set the jumper in the RS232 position
(RS232 communication parameters are set to default values) to send the
configuration strings to STARModem™ via serial interface and set the jumper
back in Wedge/Pen Emulation position to enable this kind of connection.
For jumper setting, open the antenna support by means of the 2 screws as
shown in the following figure:

CONFIGURATION
Once the modem is setup, you can change the default parameters to meet your
application needs by sending the desired strings to the modem via serial interface.
Refer to chapter 3 for initial configuration in order to set the default values and if
necessary select the interface for your application.
The following table lists all configuration commands which do not require the $character:

It is always possible to activate the modem in temporary mode by
pressing the “s” (lower case) key on the keyboard and connecting
simultaneously an external power supply to the power jack provided
on the modem 9-pin cable connector. When working in temporary
mode, you can get the modem current configuration and its software
release. Furthermore, it is possible to send a command string starting
with the $+ characters and terminating with the $- characters. To exit
the temporary mode simply reset STARModem™.
The communication parameters must be set to 9600 baud, no parity,
8 data bits, 1 stop bit, handshaking disabled.
CONFIGURATION
In this manual, the configuration parameters are divided into logical groups making it
easy to find the desired function based on its reference group.
The first three groups are for Standard Interface parameter configuration:
•
RS232
•
WEDGE
•
PEN EMULATION
The following parameter groups are common to all interface applications:
DATA FORMAT parameters regard the messages sent to the Host system for all
interfaces except Pen Emulation.
RADIO PARAMETERS allow configuration of radio protocol parameters.
NOTE
It is strongly recommended to read par. 5.1 in Radio and Serial
Communication controls and the example applications in appendix A
for correct parameter settings.

KEYBOARD SETTING
ALPHANUMERIC KEYBOARD SETTING
The reader can be used with terminals or PCs with various keyboard types and nationalities
through a simple keyboard setting procedure.
The type of computer or terminal must be selected before activating the keyboard setting
command.
Keyboard setting consists of communicating to the reader how to send data corresponding to
the keyboard used in the application. The keys must be set in a specific order.
Press and release a key to set it.
Some characters may require more than one key pressed simultaneously during normal use
(refer to the manual of your PC or terminal for keyboard use). The exact sequence must be
indicated to the reader in this case pressing and releasing the different keys.
Example:
If one has to press the "Shift" and "4" keys simultaneously on the keyboard to transmit the
character "$" to the video, to set the "$", press and release "Shift" then press and release "4".
Each pressed and released key generate a yellow LED on the device, otherwise repress the
key. Never press more than one key at the same time, even if this corresponds to the normal
use of your keyboard.
Press "Backspace" to correct a wrong key entry.
Note: "CAPS LOCK" and "NUM LOCK" must be off before starting the keyboard setting
procedure. "SHIFT" must be repressed for each character and cannot be substituted by
"CAPS LOCK".

press the keys shown in the following table according to their numerical order.
Some ASCII characters may be missing as this depends on the type of keyboard: these are
generally particular characters relative to the various national symbologies. In this case:
•
The first 4 characters (Shift, Alt, Ctrl, and Backspace) can only be substituted with
keys not used, or substituted with each other.
•
characters can be substituted with other single symbols (e.g. "SPACE") even if not
included in the string set used.
•

5.1
RADIO AND SERIAL COMMUNICATION CONTROLS
STARModem™ communication (both radio and serial) can be controlled by several
parameters depending on whether it is a Client or Server. STARModem™ can act
as both Client and Server in each of the Stand Alone and STAR-System™ Modes.
In the STAR-System™ Mode, bi-directional communication means that
STARModem™ can dynamically switch from being Client to Server and vice versa.
The following table summarizes which parameters are controlled by the Client and
which ones are controlled by the Server.
Client (Transmitter)
controlled parameters:
Transmission Mode
ACK/NACK From Remote Host
FIFO
Handshaking
Single Store
NOTE
38
Server (Receiver)
controlled parameters
ACK/NACK Protocol
Handshaking
To avoid incorrect interpretation of ACK characters, ACK/NACK
Protocol and ACK/NACK from Remote Host cannot be
simultaneously enabled on the same STARModem™.
REFERENCES
To help understand the various communication control possibilities among the
different communication modes, we will analyze the communication control
parameter settings for the following 4 cases:
1) STARModem™ in Stand Alone Mode acting as Server (like an OM-cradle)
2) STARModem™ in Stand Alone Mode acting as Client (like an RF device)
3) STARModem™ in STAR-System™ Mode
4) STARModem™ in Stand Alone Mode acting as Server (for an intelligent printer)

Figure 16 – Stand Alone Mode with STARModem™ Server
STARModem™ is in Stand Alone Mode as a dedicated Server receiving (like an
OM-cradle). The ACK/NACK Protocol parameter can be set to assure correct
communication between STARModem™ and the local Host.
Assuming the RF devices are setup for 2 way transmission we can analyze the
following ACK/NACK protocol selections:
RF devices - Transmission Mode = 2 ways
The Host must respond to a 2 way transmission
•
If Modem - ACK/NACK = disabled
there is no control of the communication between STARModem™ and the
Local Host. STARModem™ answers the RF device which initiated the 2 way
transaction with DATA received from the Local Host.
39
STARModem™
•
If Modem - ACK/NACK = enabled
when the Local Host receives a message correctly, it answers STARModem™
with the ACK character. Only then does STARModem™ acknowledge the RF
device which initiated the 2 way transaction with an Empty Answer.
•
Modem - DATA/NACK = enabled
when the Local Host receives a message correctly, it answers STARModem™
with DATA. STARModem™ then answers the RF device which initiated the 2
way transaction with this DATA (i.e. command to RF device display).
Case 2 – STARModem™ in Stand Alone Mode as Client (like an RF device)

2
Figure 17 – Stand Alone Mode with STARModem™ 2 Client
In the figure above, STARModem™ 2 is in Stand Alone Mode as a dedicated
Client (as an RF device). The following parameters may be set depending on the
application:
Modem 1 - ACK/NACK = enabled
Scanner - Handshaking= RTS/CTS
•
If Modem 2 -
Transmission Mode = 1 way
ACK/NACK from Remote Host = disabled
FIFO = disabled
Handshaking = Modem (RTS/CTS)
In this case, Modem 2 sends data (messages) to the Remote Host. The special
case of FIFO disabled blocks transmission of the scanner until an
acknowledgement is received from Modem 1. Because ACK/NACK is enabled
for Modem 1, only after Modem 1 has received an ACK from the Remote Host
does it acknowledge reception (Empty Answer to Modem 2).

Modem 1
Modem 2
HOST 1
HOST 2
Figure 18 – STAR-System™ Mode
Both STARModems™ are in STAR-System™ Mode and are therefore able to
communicate bi-directionally. For analysis purposes only, we assume the situation
where Host 1 is Client and Host 2 is Server. It is clear that the situation is analogous
in the opposite direction:
•
If Modem 1 -
Transmission Mode = 1 way
ACK/NACK from Remote Host = disabled
FIFO = enabled
Handshaking = any
The Client, (Host 1) sends a message to the Remote Host (Host 2), but no
control exists upon reception and even if ACK/NACK Protocol is implemented on
the Server side (Remote Host), no answer is returned from Modem 2 to Modem
1 (except for a single blink from the red LED on Modem 1 if radio transaction has
failed). This is not a secure communication.
•
If Modem 1 -
Transmission Mode = 1 way
ACK/NACK from Remote Host = enabled
FIFO = enabled
Handshaking = any
The Client, (Host 1) sends a message to the Remote Host (Host 2). Modem 2
acknowledges good radio reception but no control is made on Remote Host
reception. If Modem 2 acknowledges radio reception within the Radio Protocol
Timeout, Modem 1 sends ACK to its local Host, otherwise it sends NACK.
41
STARModem™
•
If Modem 1 -
Transmission Mode = 2 ways
ACK/NACK from Remote Host = enabled
FIFO = enabled
Handshaking = any
Single Store = enabled
The Client, (Host 1) sends a message to the Remote Host (Host 2) and expects
an answer from Host 2. Host 2 answers with DATA (a string of up to 238
characters). If Modem 2 sends this DATA answer within the Radio Protocol
Timeout, Modem 1 sends it to its local Host (Host 1), otherwise Modem 1 sends
NACK. In addition, the Single Store parameter upon Radio Protocol timeout,
causes Modem 1 to retry transmission of the same message the defined number
of times, before responding to its local Host (Host 1) with NACK.
Host 1 •
Handshaking = RTS/CTS
If Modem 1 -
Transmission Mode = any
ACK/NACK from Remote Host = enabled
FIFO = disabled
Handshaking = Modem (RTS/CTS)
The Client, (Host 1) sends a message to the Remote Host (Host 2). Modem 1
after receiving the message, blocks transmission of Host 1 until communication
is completed according to the other communication control parameter settings as
described above.
NOTE
NOTE
42
The most secure settings for bi-directional communication in
STAR-System™ Mode is to have ACK/NACK from Remote Host
enabled and Two-way transmission at both ends. In addition, in case
the first transmission fails, the Single Store parameter automatically
repeats transmission of the same data packet up to the number of
specified attempts.
When STARModem™ acts as Client and STARGATE™ acts as
Server, FIFO disabled only works if two-way transmission mode is
set.

however this limits one to be the dedicated Client and the other to be the dedicated
Server. Bi-directional communication is not possible in Stand Alone modes.
Assuming that Host 1 is Client we can analyze the following transmission parameters
from both STARModem™ 1 and STARModem™ 2’s point of view :
Modem 1 Client
Transmission Mode = 2 way
ACK/NACK from Remote Host = enabled
FIFO = enabled
Handshaking = any
The Client, (Host 1) sends a message to the Remote Host (Printer) and expects
an answer from the Printer. If the answer doesn’t arrive before Radio Protocol
Timeout, Modem 1 sends NACK to the Local Host.
•
If Modem 2 Server
ACK/NACK Protocol = enabled as ACK/NACK
When STARModem™ 2 receives a new message, it sends it to the Printer.
The Printer answers with ACK. If Modem 2 acknowledges within the Radio
Protocol Timeout, Modem 1 sends an Empty Answer to its Local Host (Host 1),
otherwise it sends NACK.
•
If Modem 2 Server
ACK/NACK Protocol = enabled as DATA/NACK
When STARModem™ 2 receives a new message, it sends it to the Printer.
The Printer answers with DATA (a string of up to 238 characters). If Modem 2
sends this DATA answer within the Radio Protocol Timeout, Modem 1 sends it to
its local Host (Host 1), otherwise Modem 1 sends NACK.

5.2.2
ACK/NACK Protocol
This parameter sets a transmission protocol which takes place between
STARModem™ (Server) and Local Host in RS232. An RF device (such as a handheld reader) passes its data (code read) to the modem which sends it to the Host.
The Host sends an ACK character (06 HEX) to the modem in the case of good
reception; a NACK character (15 HEX) requesting re-transmission is sent to the
modem in case of bad reception.
In the particular case where the RF device is configured for 2 way transmission and
therefore requires an answer, it is advised to set STARModem™ with the
DATA/NACK protocol. The DATA answer from the Local Host is implicitly considered
an ACK and is sent to the RF device. If instead ACK/NACK is used, the modem
generates an Empty Answer to the RF device.
Before selecting this parameter ensure that “ACK/NACK from
Remote Host” is disabled (see par. 5.5.5).

If the modem does not receive an ACK, DATA or NACK, transmission is ended after
the RX Timeout (see par. 5.2.3 ). See also Radio Protocol Timeout, par. 5.5.3, for
radio transmission to RF devices.
For ACK/NACK selection when STARModem™ as Client, is transmitting to a
destination device connected to a Remote Host refer to par. 5.1.
5.2.3
RX Timeout
This parameter can be used to automatically end data reception from the Local Host
after the specified period of time.
If no character is received from the Local Host, after the timeout expires, any
incomplete string is flushed from the modem buffer.
Refer to par. 5.2.5 for RX Timeout functioning when defining the frame packing.
5.2.4
FIFO
If enabled, the Destination Device collects all messages sent by STARModem™
and sends them in the order of acquisition to the connected Remote Host.
If disabled, STARModem™ blocks the message transmission from the Local Host
until an answer signaling the right/wrong message transmission has been received
from the Destination Device (1 way) or the Remote Host (2 way). Once the answer
has been received, the Local Host is allowed to send a new message.
This command requires the Modem (RTS/CTS) handshaking to be enabled.
For more details about the Transmission Mode refer to par. 5.5.2.

STARModem™
5.2.5
Frame Packing
This parameter defines the format of the frame to be transmitted between
STARModem™ and the Host.
The frame received by STARModem™ may contain a maximum of 238 characters.
All characters not included within this number will be transmitted from the Host in a
new frame.

Correct FRAME identification is managed by frame packing. Three different types of
frame packing can be selected:
•
Frame+ [CR] (default): the frame sent to STARModem™ is terminated by
[CR]. This means you cannot use the [CR] character within the frame.
In Frame + [CR] mode, make sure the FRAME does not contain [CR], nor begin
with $+ or #+ characters.
[CR]
FRAME
The frame transmitted by STARModem™ has no additional field. In this case
the end of the FRAME is either DATA or Terminator if any.
FRAME
•
[STX]+LEN+Frame+[CR]: both frames sent to and by STARModem™ are
preceded by [STX], LEN and terminated by [CR], where LEN is a field of 4 digits
and indicates the FRAME length in number of characters, that is FRAME +CR.
[STX]
LEN
FRAME
[CR]
The [STX], [CR] and [ESC] characters contained in the frame must be preceded
by the [ESC] character for a correct transmission.
•
Frame after Timeout: if the delay between two consecutive characters is more
than the selected timeout, the modem considers the frame completed. The
timeout corresponds to 1/10 of the value defined for RX Timeout (see par. 5.2.3).
Therefore, the timeout for frame packing is calculated in ms (from 10 ms to 990
ms).
NOTE
It is not possible to disable this timeout, therefore possible
values are in the range 10 - 990 ms. If RX Timeout is disabled,
Frame after Timeout is 10 ms.
Both the frames sent to and by STARModem™ have no additional fields:
FRAME
All commands to be sent using this frame packing must be preceded by the
string below, which substitutes the $+ character:
#+++PROG_REQ+++#
This string is always transmitted in a single frame preceding the one containing
the configuration command, as shown in the following examples:
49
STARModem™
Example 1
Sending the $+$![CR] command to transmit the modem software release:
1st Frame = #+++PROG_REQ+++#
nd
2 Frame = $![CR]
Example 2

configuration:
st
1 Frame = #+++PROG_REQ+++#

2 Frame = ML0$-[CR]
5.3
PEN EMULATION PARAMETERS
5.3.1
Minimum Output Pulse
This parameter sets the duration of the output pulse corresponding to the narrowest
element in the barcode. In this way the code resolution is controlled by the signal
sent to the decoder, independently from the physical resolution of the code read.
The shortest pulse (200 µs) corresponds to a high resolution code emulation and
therefore a shorter transfer speed to the decoder (for decoders able to work on high
resolution codes). Likewise, longer pulses correspond to low resolution code
emulation and therefore a longer transfer time to the decoder.
5.3.2
Overflow
This parameter generates a white space before the first bar and after the last bar of
the code. The selections are as follows:
narrow
= space 10 times the minimum output pulse.
medium
= space 20 times the minimum output pulse.
wide
= space 30 times the minimum output pulse.
5.3.3
Conversion to Code 39 and Code 128
This parameter allows converting the decoded codes into either Code 39 format or
Code 128 format. It is not possible to disable conversion.

Header/Terminator Selection
The header/terminator selection is not effected by restore default command. In fact,
header and terminator default values depend on the interface selection:
RS232:
no header, terminator CR-LF
WEDGE:
no header, terminator ENTER
These default values are always restored by sending the RS232 or WEDGE interface
selection string, see par. 3.1.1.

SET CUSTOM EXTENDED HEADER/TERMINATOR KEYS
The extended Header/Terminator keys for Wedge Interface users can be
customized by defining them through a simple keyboard setting procedure.
For example, the Numeric Keypad keys can be set for use as Headers or
Terminators by substituting the default extended keys using this procedure.
The type of computer or terminal must be selected before activating the keyboard
setting command.
Press and release a key to set it.
Some characters may require more than one key pressed simultaneously during
normal use (refer to the manual of your PC or terminal for keyboard use). The exact
sequence must be indicated to the reader in this case pressing and releasing the
different keys.
Example:
If one has to press the "Shift" and "4" keys simultaneously on the keyboard to
transmit the character "$" to the video, to set the "$", press and release "Shift" then
press and release "4".
Each pressed and released key must generate a yellow LED blinking on the device,
otherwise repress the key. Never press more than one key at the same time, even if
this corresponds to the normal use of your keyboard.
Press "Back space" to correct a wrong key entry.
Note: "CAPS LOCK" and "NUM LOCK" must be off before starting the keyboard
setting procedure. "SHIFT" must be repressed for each character and cannot
be substituted by "CAPS LOCK".

is a new message that an RF device sends to the STARModem™ Server. See par.
5.4.2 for details.
5.4.2
Address Stamping
If enabled, this command includes the RF device or STARModem™ address in the
message/answer transmitted. It is advised to enable this parameter when
STARModem™ is a Server for more than one Client in 2 way transmission. In this
way the Host knows to which Client the answer must be sent.
If receiving data from an RF device working in 1 way mode, STARModem™ (Server)
automatically includes the RF device address in the message to be sent to the Host.
If receiving data from an RF device working in 2 way mode, STARModem™
(Server) automatically includes the RF device address in the message to be sent to
the Host. It is required to set the Host application to include the same address in the
answer to be transmitted back to the RF device.

REFERENCES
NOTE
5.4.3
If communicating with only one RF device in 2 way mode, Address
Stamping is not required, since the data/answer generated by the
Host is only sent to that device. In this case STARModem™ can
receive data (messages) via radio only after sending the 2 way
answer.
Address Delimiter
The Address Delimiter allows a character to be included to separate the Address
stamping fields from the next fields in the message. Once enabled, it is required to
set the Host application to include the Address Delimiter character in the message.
Any character can be included in the hexadecimal range from 00 to FE.
5.5
RADIO PARAMETERS
5.5.1
RF Baud Rate (not for USA Model)
This parameter defines the baud rate used for radio communication. For
STARModem™ USA model the baud rate value is always set to 36800, while for
European models it can be set to 9600 or 19200 according to the device
communicating with STARModem™.
5.5.2
Transmission Mode (Client only)
STARModem™ Client can communicate within the system using two different
transmission modes:
•
1 way mode:
(default)
•
2 way mode:
STARModem™ transmits data without requiring an
acknowledgement answer from the Remote Host (see par. 5.1
for details).
STARModem™ transmits data requiring an acknowledgement
answer from the Remote Host (see par. 5.1 and par. 5.5.5 for
details). When the destination device is connected to the
Remote Host through the Wedge Interface, it considers the
transmission successful after data has been sent. Therefore, an
Empty Answer is generated and passed back to the modem.
57
STARModem™
5.5.3
Radio Protocol Timeout (Client only)
This parameter sets the valid time to wait before radio transmission between
STARModem™ and a destination device is considered failed.
This parameter should be set taking into consideration the radio traffic (number of
devices in the same area).
If the RS232 interface connecting the Remote Host and the destination device is
used with ACK/NACK enabled, this parameter should be at least equal to the RX
Timeout parameter for low traffic environments. It should be increased if there are
many devices in the same area.
5.5.4
Single Store (Client only)
This command is active when STARModem™ (Client) transmits messages/data to
a destination device.
It guarantees a secure control to prevent the transmission of duplicated data.
If Single Store is enabled and STARModem™ does not receive any answer of
good transmission from the destination device, it enters a special operating mode
that stops sending new messages. When such operating mode is entered, the
modem retries transmission itself for the number of attempts selected in the
configuration. Once the transmission is successful, the modem continues to send
new messages. If transmission is not successful after the number of configured
attempts, the message is lost.
To be absolutely sure that messages are received by the destination device, set
Single Store to continuous. A new message will not be sent unless the previous one
is received. If using Single Store as continuous, and the transaction is not received,
check that the Server is active and that the STARModem™ configuration is correct.
If your application requires an acknowledgement from the Remote PC, you must
define Single Store and enable ACK/NACK From Remote Host (see par. 5.5.5).
5.5.5
ACK/NACK From Remote Host (Client only)
This parameter sets a transmission protocol which takes place between the
STARModem™ (Client) Host and the destination device Host (Remote Host). The
transmission is influenced by the transmission mode selected (see par. 5.5.2).
Before selecting this parameter ensure that “ACK/NACK Protocol”
is disabled (see par. 5.2.2).
CAUTION
58
REFERENCES
One way mode:
Host sends a message to STARModem™ which passes it to the destination device
via radio. In case of good transmission, the destination device transmits a radio
acknowledgement back to the modem. If received before the Radio Protocol Timeout
expires, STARModem™ sends an ACK character to the Host. If the timeout expires
before receiving any acknowledgement, the modem transmits a NACK character.

destination device. Then, the modem transmits it to the Host.
If the Radio Protocol Timeout expires before the answer from Remote Host is

STARModem™
5.5.6
Beacon (Client only)
This parameter is available only when STARModem™ is used in STAR-System™
applications and is connected to a device (Local Host) without transmitting or
responding capability. It is particularly useful when STARModem™ Client transmits
data to a STAR-System™ Server (never sending data back to STARModem™ in
asynchronous mode). If the modem does not receive any command or data from the
Host for the defined period of time (intervals of 2..30 seconds), it starts a 2 way
transmission towards the system waiting for data to be sent to the connected Host
(refer to the example in par. A.4).
The selection of this parameter does not influence the modem normal radio
transaction. This means that it does not modify the transmission of data sent by the
Local Host.

GLOSSARY
1 way transmission
a radio transmission in which STARModem™
transmits
data
without
requiring
an
acknowledgement answer from the remote Host.
2 way transmission
a radio transmission in which STARModem™
transmits data requiring an acknowledgement
answer from the remote Host.
Client
a radio device which can initiate a 1 way or 2 way
transmission to a Server. The Client is also
defined as Transmitter. STARModem™, RF
terminals or RF hand-held readers function as
Clients.
Server
a radio device which is continuously waiting for a 1
way or 2 way transmission initiated by a Client.
The Server is also defined as Receiver.
STARModem™ or OM-cradles function as
Servers.
Bi-directional Communication
the ability to both receive radio messages as a
Server and to initiate radio transmission as a
Client.
Destination Device
the radio device to which a message must be sent
or to which an answer to a previously received
message must be given.
DATA
a string of up to 238 characters sent as an answer
from a Remote Host to a Client.
Empty Answer
a radio acknowledgement
information (data) content.
Local Host
the Host to which STARModem™ is physically
connected through a cable. This can be a PC, a
device such as a scanner, or other peripheral
device such as a printer.
Remote Host
the Host to which a transmitting STARModem™
Client sends a message via radio.
72
containing
no
STAR-System™
a Datalogic radio communication system that uses
a Narrow Band RF radio and Datalogic proprietary
CSMA/CA protocol to automatically link and
manage all the RF devices in the system. In this
system
STARModem™
can
perform
bi-directional communication.
Stand Alone
a system in which STARModem™ acts as a
dedicated Server (receiver only - like an
OM-cradle) or as a dedicated Client (transmitter
only – like an RF hand-held reader). In this system
STARModem™ implements a different Narrow
Band radio protocol than STAR-System™.
