Moxa Technologies EDS-828 Communication Connections, RS-232 Connection, pin RJ45 Console Pinouts

Communication Connections

The pinout and cable wiring diagrams in this section show how the ports on the EDS-728/828 connect to other devices:

Pinouts are diagrams that indicate the type of signal passing through each of the port’s pins.

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 below to see how RJ45 pins are numbered.

RS-232 Connection

The EDS-728/828 has one RS-232 (10-pin RJ45) console port, located on the front panel. Use either an RJ45-to-DB9 or RJ45-to-DB25 cable to connect the Moxa EDS-728/828’s console port to your PC’s COM port. You may then use a console terminal program to access the Moxa EDS-728/828’s console configuration utility.
