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.
3.
Install PComm Lift software on the host PC and LEC-2050 to be your testing terminal.
