Duplex cable

The duplex cable allows a 2-way communication between an instrument and a PC in half-duplex mode (e.g. 2-

way communication but not simultanuously).

Important : Only Duplex instruments have the ability to receive RS232 commands. If you use a Duplex cable

with a simplex instrument, all commands other than "?" will be seen as a data request.

The pin assignment of a duplex cable is different to the one of a simplex cable.
