I called HEIDENHAIN tech support and received the Manual and wiring diagram for these boxes. Very strange that nothing comes up on google!
HEIDENHAIN EXE 702B (225-551-02)
Maybe this will help someone else in the future. The issue I have is that I didn't think about the cables for this unit. So I asked if they came with the cables and have yet to receive a response. If the answer is no I will cancel the buy from ebay and purchase just 3 units for the same price but With cables.

Well I canceled the order. No power cables or interface cables. By the time I bought and built all the cables I could have simply replaced the sinusoidal encoder with something more up-to-date. Such as the E5 Encoder from usdigital that passes quadrature TTL signals.
How could I setup the development board from ICHaus?
The only information I have found so far looks to be just the ic, then I would have to build it using a bread board (or custom pcb) and socket from my limited understanding so far. I assume a solution has not already been built using this ic for my purpose?
What am I missing? - And if there is information available for this build, can you point me in the right area?
just for info , i'm currently designing a board specifc for these and linuxcnc for a client , although any machine will be able to use them , if you need anything , in fact iam hunting for a resolver for testing , at the moment .
It looks like I may be able to help you out with that. The machine I plan to pick up this weekend currently has *I believe* the older sinusoidal encoder to use with the Heidenhain controller.
I could be your beta tester, or could possibly ship you my encoder for testing purposes.

No, the development board is the chip pre-mounted on a PCB, with connectors.

Counting wires might help. I think that a sinusoidal encoder will have 8 wires and a resolver will have 6.
(Also, a resolver will measure as 3 isolated resistors, probably 2 the same value and one the other)
