Subject: Re: TDC cables and DAQ upgrades

Hi Ralf,

Here the pixs you requested. I couldn't find an adapter cable marked bad.
There was one marked "difficult to attach". This one had one of the
connectors on the cable end upside down (notch on the wrong side). You'll
see in the pictures. Including the bad one, we have 6 adapters here.

Marc compared them to the installed ones and says they are the same.

Cheers,
	Steff
