Serial communication signals (RxA and TxA)
The DISCO-B4-GLONASS device incorporates a full duplex serial channel which allows two devices
to communicate directly with each other via the RS232 serial port. All supported variable baud
rates are software-controlled. It is recommended to use the DISCO-B4-GLONASS Evalboard in order
to communicate with the DISCO-B4-GLONASS device, as there you will find all you need to evaluate
with it.
This serial channel (RxA, TxA) operates at ±12 V signal level according to the V.24. The signals on
these pins are obtained to RS232 compatible signal levels.
RxA
This is the main receiving channel and is used to receive software
commands to the board from any software (e.g. HyperTerminal).
Moreover, the firmware update can also be done through this serial
port.
TxA
This is the main transmitting channel and is used to output
navigation, measurement, response and system data to any
software (e.g. HyperTerminal, FALCOM Workbench).
You may connect this port to a Bar code scanner and with the help of
the serial event
Sys.eSerialData0
you may process the incoming data from a scanner. Moreover, the incoming data
on the serial line may be forwarded/sent via TCP to an internet server and there processed/stored
into a database. Therefore, you have this data in real-time irrespective in which country they have
been scanned. The interface type and port settings of the bar code scanner must be compatible
with the DISCO-B4-GLONASS one. For more information how to implement such an application,
refer to the application note

6.1.3 4pin row connector
This interface is used to connect a MFD device to the DISCO-B4-GLONASS. The pin out is given in
table below.
