I'm trying to control a 12D-A in a Biodata Microlink 3 (GPIB) without much success. Has anyone managed to control such a device with LabView (MacOS)? In fact, if anyone has programmed such a device and has any tips on how to approach the problem, can they get in touch? The primary address is 7 and the secondary address (of the D-A) is 16... however when I use a GPIB bus analyser, an archimedes program that I know works with the device doesn't seem to specify the secondary address. I'm completely puzzled. Any help much appreciated!
