3) The EA-LAN1 DB9 pin definition for an RS485 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-

4) The RS485 connection must be matched with the device being used with the

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

5) Connect the DB9 of the EA-LAN1 to the Main Module as follows:

DB9

(Pin # - Pin Name)

RS485 on Main Module

(Pin # - Pin Name)

2 – RX 11 – RS485_B

3 – TX 10 – RS485_A

5 – GND 12 – GND

6) The EA-LAN1 should now be properly connected to the controller.

Double check the connection, and verify that the power and the Ethernet

are both connected to the EA-LAN1.

Installing the “COM Port Simulation” Driver on the

Admin PC

The COM Port over TCP/IP driver must be installed on the admin PC to allow

Windows to communicate with the EverAccess controller through the net. In this

chapter you will learn how to install this driver and be able to map it to the COM

ports available through the PC. The following two sections in this chapter help

explain:
