Need External Voice Guard box pinouts, AEGIS VGE

[redbeard]

I have two of these boxes, one Rev. J still marked as GE and a newer Rev. S that was marked as Ericsson but with M/A-Com stickers covering the Ericsson labels. Both are part number 19A148909P and are identical except for front face markings, the older one just says 'Digital SPeech Encryption' while the newer one makes reference to 'AEGIS Encryption'

I am told both are the same and I hope someone more familiar can tell me for sure. What I'd like to do is find out the pinouts so that I can hook these up to a pair of radios for a secure link. I will figure out what radios I will need based on what i/o is required from the radio. I have 16-pin Maxtracs now so it would be great if I can make those work. Also keyloading is not a problem, I know someone who can load these for me.

TIA

Shawn
