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 the baud rates of the instrument

and the PC 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.
