This optional module has been designed to convert one of the internal USB ports available on connector CN17 into a serial
port, which can be of RS-232, RS-422 or RS-485 type.
Depending on the type of serial port needed, different module configurations are available; moreover, the output of the
module can be available on standard DB-9 male connector or on RJ-45 sockets.
Using these modules, it will be possible to have additional serial ports, other than those available on connector CN27.
Moreover, it will be possible to have RS-422 or RS-485 ports, which are functionalities not directly supported by CCOMe-
