Protocol
COM Port parameters
If you use one of the COM ports for the connection , values such as Speed, Bit count, Parity,
Stop Bit, IrDȺ mode (for data transfer via infrared port) must be identical with
Communication Server setting.
TCP/IP Parameters
With ɌɋP/IP, you have to specify the IP address of the computer to which the connection will
be made and the number of the logical port for the connection to Communication Server.
Depend on type of connection. The most versatile is the Ethernet TCP/IP protocol.
Connection
10
Several protocols of data transfer are available :
1. PointToPoint
2. UDP - User Defined Protocol
3. EUDP - Enumerated User Defined Protocol
PointToPoint: is the simplest protocol that doesn’t use control character. The data blocks
division is done by a timeout.
UDP: is point to point protocol with an additional control character (check sum) and a start and
end of block character.
EUDP: is the most stable protocol. By its functions this protocol corresponds to the UDP but
with a block number. This protocol is recommended and defaulted into the dialog box
Configuration Parameters.
Picture 5: The Configuration Parameters transfer
Parameters of data transfer are specified in the Configuration Parameters dialog box. These
Parameters of transfer concern data transfer protocol and type of connection (IP computer
address, to which connect PDA, port number or parameters of the COM port connection (all
depend on the type of connection).
Note: Commands specified in the Configuration field are compatible only with the
Communication Server.
