SH612 RS-422 Control Pinout
 

Hello Avid DUC members,

Just joined and my first post, even though I've been using Avid products for over a decade now.

At the office we have a Euphonix SH612 MADI router and it seems during the upgrade of our video router, the control cable that ran from our previous router controller to the SH612 was lost.

Going through every manual and document I can find, I can't seem to find the pinout of the control port that is on the back-bottom-right of the unit, just to the left of the 3 IEEE1394 ports. I was able to find that the port is RS-422 (I found this by looking at the setting on the previous router controller and what it was set to), but I can't seem to find what the pin-out for the SH612 is...

Does anyone where I can find this info, or have it on hand?

Thanks in advance.

I'm pretty sure its a standard RS422 pinout...Google has the diagrams.

So looking around, there is no standard RS-422 pinout, it can literally be anything. That said, the closest thing to a standard for the world of routers (video and audio) is the Sony RS-422 pinout.

According to the SH612 manual, one needs to use a straight through male-male cable, and the assumption is that you're hooking the sh612 up to a Grass Valley Venus (RM) 3000 control system. Said system uses the Sony RS-422 pinout.

All of that said, the cable is straight through, which means the pins on the SH612 are the same as the Sony RS-422 pinout in slave mode:


Pin SH612
1 Frame ground
2 Transmit A
3 Receive B
4 Receive common
5 Spare or ground Spare or ground
6 Transmit common
7 Transmit B
8 Receive A
9 Frame ground

The cable I built has all pins except 9 wired and I am able to control the SH612 using an NVision/Miranda/Grass Valley NV9000 (which doesn't follow the Sony pinout for their RS-422 connectors) and Utah Scientific Systems MX-Lator.
