Serial communication signals (RxA and TxA)
The DISCO-B4 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 Evalboard in order to communicate with the DISCO-B4 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 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. The pin out is given
in table below.
