2) Can't send commands remotely over GPIB interface

A modification to the GPIB interface of the SR245 Computer Interface Module was implemented in June 1991. A 270 pF capacitor was added between pin 10 (ground) and pin 17 (DAC) on the GPIB bus driver (part number 75161, adjacent to the MC68488 controller). If you have an old unit, check to see if there is a capacitor installed between pins 10 and 17 of the 75161 chip (located near the GPIB connector). If a 270 pF capacitor isn't soldered between these pins, you will need to install one before GPIB communication is possible.

 

If you are still having trouble your SR245, it will need to come back to SRS for service. Click here to get an RMA number.
