As delivered from the factory, COM2 is configured for RS-232 communications.  This 
port can be reconfigured for operation as a non-isolated, half-duplex RS-485 port. Using 
COM2 for RS-485 communication disables the USB port. To configure the instrument 
for RS-485 communication, please contact the factory.
