4.2.4. COM1 and COM2
RipEX provides two serial interfaces COM1 and COM2 terminated by DSUB9F connectors. COM1 is
always RS232, COM2 can be configured as RS232 or RS485 (more in
Adv. Conf., COM's
).
RipEX‘s RS232 is a hard-wired DCE (Data Communication Equipment) device. Equipment connected
to the RipEX’s serial ports should be DTE (Data Terminal Equipment) and a straight-through cable
should be used. If a DCE device is connected to the RipEX‘s serial ports, a null modem adapter or
cross cable has to be used.
