INTRODUCTION
MOD-GSM is excellent board for adding remote monitoring and control with the
use of the GSM cellular network. With this module you can use all of the the
features of each one of Olimex's boards with on-board UEXT connector by GSM
network. Also the board can work in stand alone mode, but only when the SIM
card is without PIN code. In stand alone mode MOD-GSM don't offer much
opportunities. It can receive information by GSM network, but if you want to
operate with this information, you will need appropriate board with UEXT
connected to MOD-GSM. Choose the other board depending on the application
you want to have. MOD-GSM contains quad-band GSM GPRS module
850/900/1800/1900Mhz inside which covers most used GSM networks around the
world. The GSM antenna is build in the board so no need for external expensive
GSM antennas.

POWER SUPPLY CIRCUIT
The power supply of MOD-GSM may be done in two ways:
1.
Power from +9 - 12VDC without using the external backup battery.
In this case the external power supply is used for supplying of 4V to GSM
module and thus the module can be powered only from external power
supply and the battery must not be connected.
In this case the jumpers have to be configured as follows:
− jumper BAT_E must be open
− jumper 4V_E must be closed
− jumper 4V must be closed
− jumper 5V_CHG_E must be open.
− DCDC_E must be closed
Power consumption in this mode is:
− near to 70mA when have a conversation.
− around 20mA in normal mode (without conversation).
Important: 4V_E, 4V and 5V_CHG_E jumpers have to be moved together.
2. Power from +12VDC with external 4.2V Li backup battery. The GSM module
is powered always via the battery voltage and the external power supply is
used only for charging the battery if it is discharged, i.e. if you have
plugged external power supply the battery will be charged and if the board
is not powered from external power supply the board will work until the
battery dies.
In this case the jumpers have to be configured as follows:
− jumper BAT_E must be closed
− jumper 4V_E must be open
− jumper 4V must be open
− jumper 5V_CHG_E must be closed
− DCDC_E must be closed
− Power consumption in this mode:
Depends on live of the battery and vary from 260mA to 330mA (fully
discharged battery). If we supply the module only via battery, without
external power supply, the current through the battery is between 15mA
and 30mA if there is no conversation, and between 180mA - 240mA when
there is conversation.

JUMPER DESCRIPTION
BAT_E
Connects 3.7V Li-ion battery to the GSM module. Default state is to be open to not
drain the battery during stocking the modules.
Default state - open
4V_E
This jumper is used when power the module without
enable 4V to the DCDC output.
battery.
When connected
Default state – open.
4V
This jumper is used when power the module without battery. When connected the
jumper enable 4V to VBAT power pins of SIM340D module.
Default state – open.
5V_CHG_E
This jumper is used when the battery is present and allows battery charging.
Connects the DCDC converter output (5V or 4V according 4V_E jumper state) to
VCHG power pin of SIM340D module.
Default state closed
Important: 4V_E, 4V and 5V_CHG_E jumpers have to be moved together.
Do not plug in external +12V if BAT_E jumper is open!
DCDC_E
Enable DCDC. Connect DCDC output ((5V or 4V according 4V_E jumper state) to the
module.
Default state closed
Download
When the jumper is closed allow SIM340D firmware upgrade.
Default state is open
DTX/ MTX
The DebugTX/MainTX defines whether Debug TX terminal or Main TX terminal of
SIM340D module is connected to FT232RL virtual com port driver.
Default state is DTX
Page 10
DRX /MRX
The DebugRX/MainRX define whether Debug RX terminal or Main RX terminal of
SIM340D module is connected to FT232RL virtual com port driver.
Default state is DRX
AGND_E
Enable board analog ground.
Default state is closed
INPUT/OUTPUT
PWRKEY button – turns on the MOD-GSM module. You can turn on the SIM340D
by driving the PWRKEY to a low level voltage for period time from 500mS to 1S
Status LED ( red) with name STAT – indicates the state of SIM340D module.
STAT is off state - SIM340D is not running
64ms On/ 800ms Off - SIM340D does not find the network
64ms On/ 3000ms Off - SIM340D find the network
64ms On/ 300ms Off - GPRS communication
IMPORTANT NOTE ABOUT THE UEXT
The information below is for older revisions of the board. If your board doesn't
have the serial resistors mentioned below then there is no need to perform the
actions mentioned below!
If MOD-GSM doesn't transmit properly data on the UEXT of another Olimex board,
it might be because some other boards can interfere with MOD-GSM's signals. If the
host board has any signal on the I2C and/or the SPI on the UEXT there is very high
chance of erroneous behavior.
There are two workarounds:
1. Cut the UEXT cable wires 5,6,7,8,9,10. Only wires 1,2,3,4 (NC, GND, RXD, TXD)
should remain.
OR
2. Remove resistors R19, R20, R21, R23, R24, R25
