Bingo,
The manuals DID work... So you get a TON of 'attaboys! ![Cheesy :D](https://www.eevblog.com/forum/Smileys/default/cheesy.gif)
Glad it helped
Can I offer you something in return? I'm not used to asking for help and not returning the favor.
No need to ... This is EEV....
One last thing... the 100334-004 came inside a metal tank bulletproof hazmat box (read: metal). The box has a 25 pin connector and three TNC connectors, one of which is already labeled as 10MHz Out. Obviously not a necessity, but I'd love to keep the unit itself in the metal enclosure. If you come across something that shows this pinout, I'll be insanely happy.
I'd keep it in the box too, you do need to attach the Rubi to a Heatsink OR Metal casing , to keep the Rubi Casing temperature at a sane level (prolongs lifetime)
But it seems like a "Custom casing", I have never seen such a beast ...
Well maybe because most *bay Rubis' are stripped out of the box.
Now you have to start tracing the 25-pin connector to the "inside" (Maybe use a DMM)
You do have a "Known reference" ... The 15-pin Rubi Plug "pinout"
And maybe post some pics of the case and PCB/Wiring inside.
There are a lot of people here, that have seen/worked with - Weird boxes ....
Edit: Is it like this one ? ... Still unknown to me , but looks like there might be "Cleanup Osc" on the PCB ... Fine stuff
