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.
