Cable needed for back of HP 70611a module
(1/1)
cncjerry:
I bought an HP 70K spectrum analyzer and added the 70611a switch module to control some attenuators and RF switches. I bought a cable that was listed as needed to connect an 84940a driver board not realizing that another cable, termed a 36-Pin SCSI II cable was needed to bridge them. See the layout in the attached picture that I found later. These cables aren't cheap as you can imagine. All the 36-pin cables I found have a different connector, more like a parallel printer connector.
I have just about all the different types of SCSI cables from years ago except that needed. The pins are sticking out on 70611a and now the 70611-60011 cable, that happens to be the same cable inside the 70611 module. so I guess I would need a female/female SCSI cable listed as 70611-60010 in the picture. The connector is 7mm wide by 33.5mm tall as in the attached picture.
In the meantime I was able to open the module and just use a 34-pin ribbon to link the module's internal circuit board to the driver board (two pins aren't used in the SCSI jumper) to the external card but I'd like to put it all together as it was meant to be.
I think I've looked at every 36 pin SCSI cable out on the web and haven't found the correct cable.
Thanks for the help.

Hi!
I think the connector is a Mini D Ribbon / MDR.

I don't think that is a Mini D Ribbon / MDR connector. Looks more like an opposite gender HD SCSI type connector, and only 36 pins instead of the normal HD50 SCSI.
I doubt a pre-built replacement cable could be found anywhere else except for an HP original 70611-60011 cable.
If you wanted to try building a cable yourself, one source of mating connectors might be from Honda (HTK, or HONDA TSUSHIN KOGYO CO., LTD), in particular the PCS Series 1.27 mm Pitch Interface Connectors. PCS Series catalog attached below.
PCS-E36FA Cable Connectors Female Straight IDC
PCS-E36FS+ Cable Connectors Female Straight Soldering
In the US, onlinecomponents.com lists the PCS-E36FS+ connector in stock for $16.25, but the minimum order quantity is 10.
