RE: Communicating with the HP 3421A Data Aquisition/Control Unit
I don't believe this standard, HP-IL based device is of any use at all without an HP-IL Controller (HP-41, HP-75C, HP-71B or HP-110/Portable Plus) as even though it has a small display, what is shown there is managed by the external controller.

There was also an optional HP-IB interface available for this, but again you would need an external controller computer.

What are you trying to use it for?
