6.2.3. COM PORT TESTING

The serial ports can be tested for correct connection and output in the COMM menu.

This test sends a string of 256 ‘w’ characters to the selected COM port. While the test is

running, the red LED labeled TX for that COM port on the instrument’s rear panel

analyzer should flicker.

To initiate the test, access the COMMUNICATIONS Menu (SETUP>MORE>COMM),
