Please help..Hasselblad CF 39 Digital Back H adapter

[kch1027]

Hello everyone.

I'm Frank in New Zealand.

Few weeks ago, I bought second hand Hasselblad Cf 39 digital back with V and H adapter together.
I have 503cxi and H2 both. Has used and very good working 503cxi with V adapter (used i-adapter spacer)

Recently, I tried to attach to DB with H adapter for using my H2 camera.
However, I couldn't find H camera  on the camera setting menu of the CF DB.

After attached H adapter on the Back without combined H2 camera, DB 39 camera setting nemus shown only "GX680 1&II, GX680III, Flash Sych, Pinhole, Generic" come on only 5 camera selection menu.

After DB was combined with H2 camera , Camera type in DB setting menu shown  only "LensCtrl S, Schneider, Flash Sync, Pinhole,  Generic"  there is no "H camera" and H2 LCD screen display "Digital Back has no power" massage even DB power on or sometimes "Restart Digital Back" massage.

What's wrong ? What should do i do for solving and using this H adapter.

Please advise good idea and inform please.
