HP5316a HP-IB ribbon cable

(1/4) > >>

All,

Just purchased an HP5316a off eBay, and it powers up into an E2 state (meaning something is wrong with the HPIB). Opening the device up, I notice that the cable joining the main board to the HPIB board, is missing. It's two dip sockets with a cable between them, but I'm unsure of the pinout (I plan to just make a cable). Anyone have one of these units that wants to post a good picture of the cable, and maybe even tone out the basic pin mapping (basically, is it just straight through pin 1 to pin 1, or does something cross over)?

If taking a picture, could you also take a picture of the area around the main IC. There's a small 14 or 16 pin socket in the area that's empty on mine, and appears to be that way in the documentation as well.

Thanks!

I just took some photos of my HP 5316A.  I didn't get a very good shot of that cable, but hopefully this helps.



I also had a look at the service manual, and it's just a straight through connection.

staze:
awesome, thanks. Can you confirm that small socket next to the main CPU is empty?

Thanks!

staze:
other question is, what the heck do they call these DIP cables? Am curious what one would cost, but Google-fu is failing...

Ribbon cable and IDC interconnect socket.
