I haev no idesas what the connectors on a UDA50 are, but I am sure the 
header on a DZ11 is a 50 pin thing. _Many_ years ago I wired my own 
'breakout cable' for one, to get 3 or 4 of the ports usable before I got 
the right Cabkit.

IIRC, on the DZ11 the connector is parallel to one of the short edges of 
the PCB, If you put a DZ11 in a BA11-F, the cable comes out naturally 
upwards. I thought all the connectors on the UDA50 were near the module 
handles, the cables came out of the handle side of the PCB.
