Output to RS232/GPIB

The SR850 only outputs data to one interface at a time. Commands may be received over both interfaces but responses are directed only to the interface selected by this key. Make sure that the Output interface is set correctly before attempting to program the SR850 from a computer. The first command sent by any program should be to set the output to the correct interface.
