13) The EA-LAN1 pin definition for an RS232 corresponding pin is below.

DB9 PIN # RS232 RS485-Half RS485-Full RS422

1 DCD N/A N/A RTS-

2 RXD DATA- TXD- TXD-

3 TXD DATA+ TXD+ TXD+

4 DTR N/A RXD+ RXD+

5 GND GND GND GND

6 DSR N/A RXD- RXD-

7 RTS N/A N/A RTS+

8 CTS N/A N/A CTS+

9 N/A N/A N/A CTS-

14) The RS232 connection must be matched with the device being used with the

server. In our case the device is the Main Module of the controller.

15) Connect the DB9 of the server to the Main Module as follows:

DB9

(Pin # - Pin Name)

RS232 on Main Module

(Pin # - Pin Name)

2 – RX 14 – TX

3 – TX 13 – RX

5 – GND 12 – GND

16) That’s all. Make sure the connection is correct, the power and the Ethernet

are both plugged in.

How to Connect the EA-LAN1 to an RS485 Connection

1) The DB9 is a standard 9 pin male connection. This connection is the same

as the serial connection on the PC.

2) The definition of the signal lines is below.

Name Direction Specification

1 DCD Input Data carrier wave test

2 RxD Input Data receiving

3 TxD Output Data sending

1 2 ... 9 10 11 12 13 14 15 16 17 18 19 20 21
