Part Number: MTAS7-1114SC1 I am developing code in Lab View to control instruments that are in a rack, and the Optical Attenuator is part of the instrumentation that I have to control, but I don't have a driver for it.
Have you looked on their website? I have attached 4 vi's in a zip file that i used to talk to a JDS HA9 optical attenuator. Far from being a driver, but it may get you started. The supported commands of the two units should be close but i'm not promising anything.
