Pin-out for R-402 Marker Beacon Receiver

[lr172]

I would like to pick up a Marker Beacon receiver and integrate it into the D100 EFIS. THe R-402 are quite cheap and will have lamp outputs that I could connect to the D100. My problem is that I can't find a manual identifying the 9 pins on the connector. I am sure that I could figure it out, but would have to be near marker beacon transmitters to do so.

Does anyone have a manual or know the pin configuration?

Thanks for your assistance.
