Hello The Net,

Is address 31, for talk only, a HP/Agilent feature only, or do tothers
provide talk only on the buss ?

I am looking at RF frequency counters to 12 GH, for use with TimeLab.

My understanding is that 31 is illegal as a device address, used to
untalk/unlisten all devices. Perhaps what you mention is something from
early HPIB (as opposed to newer GPIB/IEEE-488).

There are non-HP talk-only devices, but they would use a normal 0-30
device address.

But, I could be wrong, I don't pretend to be an expert on 488.

That's part of the GPIB standard. It should work on any GPIB system.

Hi Stan,

As per the GPIB standard [1], valid primary addresses are 0-30. A few
instruments use address 31 to specify TALK ALWAYS mode, but it is by no
means a standard. Not even among HP/Agilent devices.

[1] ANSI/IEEE Std 488.1-1987

Regards,
Abdul
