RS-232 Connection
The AWK-3121 has one RS-232 (8-pin RJ45) console port located on the
front panel. Use either an RJ45-to-DB9 or RJ45-to-DB25 cable to connect
the Moxa AWK-3121’s console port to your PC’s COM port. You may then
use a console terminal program to access the AWK-3121 for console
configuration.

NOTE
1. The pin numbers for male DB9 and DB25 connectors, and
hole numbers for female DB9 and DB25 connectors are
labeled on the connector. However, the numbers are
typically quite small, so you may need to use a magnifying
glass to see the numbers clearly.
2. The pin numbers for both 8-pin and 10-
pin RJ45 connectors
(and ports) are typically not labeled on the connector (or
port). Refer to the Pinout diagram above to see how RJ45
pins are numbered.
