S91-S/T

I have the misfortune in getting involved with an couple of Eicon S91-S/T X.25 interface cards.

The Eicon card has 2 connectors. The one I'm interested in is the Very High-Speed Interface (VHSI). I'm going to connect 2 of these cards together via this port for some back to back testing / software development.

All due credit to our Canadian Cousins, they do give a wiring diagram to wire up a back to back connector. But do they give a specification for the connector? NO! They just call it a 36 pin high density connector.

The Male Connector

I need to locate some male connectors. They need to mate with the pcb mounted female receptacles.

Molex Look for the 52316 IDT Series Male connector. (Molex seem a bit shy and use the term plug)

I want a solderable connector....

Seems to enjoy the name "MINI CENT. 36 MALE(C)"

Well now that I know all that - it's not so bad!

Eicon Samples

I find Eicon's web site is difficult to follow, and they change it just as I begin to find my way around it!
