Connecting the EA-LAN1 to the controller

The EA-LAN1 has three inputs: Power, Ethernet connection (RJ45) and a serial

communication (DB9) connection.

The EA-LAN1 uses a 5Volts/1Amphere direct current power source. This power

must be provided at its input on the server to turn and run the server.

The EA-LAN1 connects to the network using a standard RJ45 Ethernet cable. This

Ethernet cable must be provided at its input on the server for the server to be able to

connect to the network.

The EA-LAN1 has one more input, the DB9. This input connection is a standard

RS232 nine pin male connection. The DB9 connection can be connect to an RS232

or an RS485 connection. The following sections explain:
