DIAGNOSTICS
COM2 RS-485 Port
In previous software versions, there was no serial port
loopback test for COM2 RS-485. This software ver-
sion adds a loopback test that operates like the other
loopback tests. It performs the test by transferring data
between COM2 and COM4a and comparing transmit-
ted data to received data. Pass/fail criteria is the same
as the other tests. The loopback connections are as fol-
lows:

When performing offline control of the outputs in Jap-
anese, Korean or Chinese, the SELECTION arrow is
replaced with a green box around the selected output.

at the operator access level. The selectable formats are:
