I have this same adapter and I have been asked to use it. I have followed the instructions previously given with some success. I am using LV 8.20 and Meas. & Auto Explorer 4.1.0. I can create the TCP/IP resource and perform a validation which reports a successful connection. The problem I am having is creating a unique resource for each instrument. The test instrument in use is a Prodigit load bank and each load bank which has a unique address has four individual units that must have a unique identity in order to talk with each particular load module. I have written a program where I used a gpib card which resides in the PC and each module has its own address, such as: GPIB0::1::INSTR-0 through 3, GPIB0::2::INSTR-0 & GPIB0::3::INSTR-0. This piece of software has worked. Now, I have to use the ethernet to gpib adapter and the problem I am running into is how to talk with the other instruments on GPIB0::1::INSTR-*. Any suggestions?
