content: HelloInstalled now a E1406A GPIB controller, an E1411B voltmeter as also a E1472A multiplexer card in a E1401B mainframe...I can normally talk to the GPIB controller and also Agilent IO finds it when firing up...but no other cards can be found nor directly talked to via the secondary address set with the DIP switches...Even more...the E1411B voltmeter card shows right after power up the "failed" LED....Is there more to it to be able to talk to the cards?Only command I could find is a way to list the installed drivers, but not the detected cards like it is possible on e B-sized VXI mainframe...

content: It might not be pertinent to your problem, but there's a configuration tool for these machines. It uploads the correct drivers and runs self tests and such. Works from DOS. The drivers must be uploaded all at the same time, if there's no driver, you wont be able to talk to particular device. I hope I'm not in err and that this will help.

content: Actually it did now power up several times without any errors and I can talk to each individual card via the secondary GPIB address...fingers crossed (o;Not sure what for the drivers are then....I assume the mainframe can have several voltmeters installed, right?What about those Intel pentium controllers...do they live in harmony with a GPIB command module?

content: If this is anything like the E1300 that I had (and I believe it is), there are jumpers on the plugins that set its address. Try using this VIC software on it:ftp://ftp.keysight.com/mpusup/scpi/vic.html

content: Hmm...seems to be a temperature problem...after switching it off for a while the "config error 1" comes back....and goes away when power cycling after running it for a few minutes...

content: Received a 2nd E1411B voltmeter card from same seller....this one works just fine....so definitively the first card is broken...At least now I could swap components and see which one is temperature sensitive...
