NI GPIB card and Keithley 181 nanovoltmeter

I'm trying to control a Keithley 181 nanovoltmeter via a NI GPIB (AT-GPIB/TNT).

If I scan for instruments in Measurement and Automation, none of the devices

connected are found. However, if I go into Interactive control, use IBDEV
with
the meter turned off, then turn the meter on I can set into remote and it
works
(as long as I alternate IBRD and IBWRT). But I can't find a way of getting
it
under control in any other way so I can't use it in LabView.

Anyone have any ideas. I've always had problems with 181s using a variety

of languages.

Cheers
paul
