6. Next, configure your communications software, such as APIcom. Use the COM port

determined in Step 4 and the baud rate set in Step 5. The figures below show how
these parameters would be configured in the Instrument Properties window in
APIcom when configuring a new instrument. See the APIcom manual (PN 07463)
for more details.

Note

USB configuration requires that instrument and PC baud rates match; check the
PC baud rate and change if needed. Using the USB port disallows use of the rear
panel COM2 port except for multidrop communication.
