Some instruments have single ended listener ports, with only one data terminal. Connect this

terminal to the A terminal on the multiplexer, and leave the B terminal on the multiplexer

unconnected. Connect the ground of the instrument to the Com terminal on the multiplexer. The

instrument’s data ground is often combined with its power supply ground.

The shield terminals on the multiplexer (Shld) can be connected to the screen/shield of the cable if

available. This should always be done on one end of the cable only, preferably on the end that is

connected to a talker port.

Combining Ports

It is sometimes necessary to combine a listener and talker port of the multiplexer to connect to an

instrument. One of the most commonly used combinations is the connection of a GPS to the

multiplexer. While some GPS receivers have properly designed NMEA ports, many only have an

RS-232 port which is single ended with three terminals: TxD (data out), RxD (data in) and Ground.

The picture below shows how to connect such a GPS to the multiplexer.
