    Connect the T3H-G004 adapter to Port C or Port D on the FMX display, or Port _ on the TMX.

    A port replicator is supplied in case the port was already in use for something else, if so disconnect the device, connect T3H-G004 and then reconnect the device using the port replicator on T3H-G004.
