Serial communication signals (RxA and TxA)
The FOX 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 FOX
Evalboard in order to communicate with the FOX device, as there you will find all
you need to evaluate with it.
This serial channel (RxA, TxA) operates at V24, ±12 V level. 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 software
configuration (using the serial event
Sys.eSerialData0
) you may process the
incoming data from that 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
unimportant in which
country they have been scanned. The interface type and port settings of the bar
code scanner must be compatible with the FOX one. More about how to implement
such an application, refer to the related documents [4].
6.2 SIM card interface (Molex-91228-0002)
The figure below shows the SIM card reader interface of the FOX.
Figure 10:
View of the SIM card interface
The SIM interface (the upper slot) controls an internal small 1.8/3 V SIM card. This
interface is fully compliant with GSM 11.11 recommendations concerning SIM
functions.
Note:
The SIM card should not be removed, while the module is powered on. The
SIM card can only be removed when the FOX is shut down. To remove the
SIM card press the Eject button (see figure 10) then pull out the SIM card
holder.
