supports
RS

232
(up
to
230,400
bps)
via
RJ45
connectors.
It
also
supports
RS

422/485
via
screw
terminals
(Serial
Port
2
only).
Note:
Serial Port 2 supports RS232, RS422, and RS485, but only one mode
at a me. You can use either the RJ45 connector or the terminal block, not
both.

RJ45 Serial Connector Pinout for RS
‐
232
Note:
Termina on resistors (R=120 Ohm) are used to match impedance of a node to the impedance of the transmission (TX) line.
Termina on resistors should be placed only at the extreme ends of the TX data lines, and not more than two termina ons should
be placed in any single segment of an RS
‐
485 network. The termina on resistors may not be needed for your applica on.
