More than 10 GPIB-ENET controllers and VISA

[Jonas Lybecker]

I have a problem with VISA and GPIB-ENET controllers under UNIX.
I can only access controllers numbered 0 to 9 when I add more
controllers numbered from 10 and on they are not found as a resource
with VISA.
Anyone experienced the same?
I have extended the number of boards possible to configure with ibconf
to 128 boards and devices

Acording to the ReadMe in /opt/NI-488.2
you can use ibconf to create a new /etc/gpibrc that will support 128 boards.

This is for Version 1.2 , it requires you to be superuser.

Try checking this out, not sure if it will help but I would be interested in

knowing since I may be doi
ng this in the near future.

I just looked at the Visa Find vi and if you are using the "Easy Find..."
then it limits
the search to 0-9. You may try using the Normal "Find Resource" and put in
the
expression GPIB* to see what happens.

Also I am not real sure if it returns anything if there is no device on
the
ENET.
