Talk/Listen Modes

If you are using your GPIB-COM with a listen-only printer or plotter, you can configure the
GPIB-COM for a talk-only mode. In this mode, the GPIB-COM is always a Talker and never
sends any interface commands. To set the talk-only mode, change jumper W1 from T/L to T as
shown in Figure 2-3:
