This section illustrates a simple method to test your Serial port’s connection and data

communication.

Let’s use COM2 port with a configuration of RS-485 as an example. To configure the serial

type of COM2, refer to SC2T3/SC2T4: Select COM2 Type Jumper, Section 2.2.1

Connector Pin Assignments.

Enter to BIOS setup utility of the LEC-2050 and make sure that the serial port 2’s base

address is: 2F8.

2.

You can connect to the LEC-2050 serial device server’s COM2 serial port with a RS-232
(DB-9 female) communication cable, with the other end connecting to the host’s serial

port.
