I'm new here but I think can shed some light on these cables,
and hopefully get some ideas back as well, as I'm trying to create one from components.
I have a GR3770, PCB, SC7700, and the special ("Riso SCII") cable is missing. Total nightmare.
I'm determined to make my own however as $200 is ridiculous for some pins and plastic.
Research:
I found a product ID# on the connector coming from the PCB (Risograph) side and it reads "JAE DCUH 37S".
A quick google search brings me : here
This proves that one side of the cable is in fact a d sub.
This connector can be had for a cool $7 on eBay : here
Problem #1:
The connector end on the SC7700 presents the challenge. Unlike the other end this end has 36 pins (1 less pin), and no visible ID#. It shares the signature D shaped metal shield as the other end only much smaller. I don't think it is d-sub-micro however, because unlike the male d-sub-micro connectors which have a solid plastic bar floating in the middle (of which the pins are "embedded into"), this male connector would need to have just the pins floating alone (similar to normal d sub male cables).
Later this week I will be taking apart the SC7700 to see if I can find an ID# for this connector on the inside of the housing. If not the only other option is to do this in crude fashion - sticking pins into each of the 36 holes and wiring them accordingly to the d sub side that goes to the Risograph PCB.
Problem#2:
Does anyone here know how a 37 pin connector would wire to a 36 pin connector ??? My plan was to wire pin 1 to pin 1, pin 2 to pin 2, etc. then just leaving the odd 37th hole on the Risograph side empty. Anyone know any electronics forums that might be able to answer this?
Thanks for any help!!!! Updates to follow.
