SEL-2020 Instruction Manual
VERIFY AND TEST ALL COMMUNICATION PATHS
1. Issue the STATUS command to check that IRIG-B signal is present and devices are
connected to ports as expected. This command was used in Example 1. You can also use the
WHO command to see a list of all devices connected to SEL-2020 ports. The SEL-2020
response to the WHO command should look similar to the following screen image:
*>>WHO<ENTER>

2. Once you have established the port settings for the printer, test the connection by using the
PORT command and issuing a message as follows:

This example prints the following two lines of text on the printer and then form feeds the
printer.
This is a test.
This is the second line.
Some printers print as they receive each character, some print only when they receive a
complete line, and some do not print until they receive an entire page. This example should
