Yashica Medical 100 DX macro lens power supply

[indy_kid]

Anyone have info on the power requirements and pin assignments for this lens? Attached to a Contax RTS body with a Contax Date Back.

I'm selling it, but I'd like to see it powered up before it goes. Might be able to ask for more if the ring light and flash are functional.

Thanks!

The user manual describes the power pack as 9VDC, powered by 12 AA batteries

The connector leaves the question of which two pins provide Positive and Negative terminals!

I've toyed with the notion of having a look inside, but not yet. Still a good macro camera if you're shooting in bright daylight or have other light sources.

The power socket has 5 pins.
