RS-232 and RS-422/485 Ports
The COMX-CAR-610 implements up to six RS-232 ports, two of which can be switched to RS-
422 or RS-485 ports by setting two jumpers on the 2 x 3 pin header. All the RS-232 ports are
implemented as 2 x 5 pin, dual-row headers, and the RS-422/485 ports as 1 x 4 pin, single-row
headers.
Two of the six COM ports from the Super I/O can be configured as RS-232 ports, or as RS-422
or RS-485 ports by setting a 6-pin, dual-row jumper.
