i just had a similar problem trying to install a TCS M1 decoder, which i've never used before, using the NCE PowerCab.
on the programming track, it reported the manufacture code and version but then reported "CAN NOT READ CV" for page mode, which i hadn't seen before and the same thing while trying to set the address. The NCE manual says it may take 15 seconds to read a CV in page mode.
i finally tried to reset the decoder, which didn't seem to work initially but later, after turning everything off, the loco responded to speed and headlight in both directions.
i was able to successfully set the "reverse direction" bit in CV 29 while programming on the main and other bits. The loco jerks forward after changing a CV. So i'm able to change CV values.
wasn't able to change the decoder address.
it seems that there's an issue reading CVs.

rrinker Does it actually read that or does it time out reading and revert to showing the loco you have selected? Try Direct mode and see if it works any differently. It almost sounds like it's using physical register mode. --Randy

How long does it take to timeout? I have not done direct mode programming before. Is the routine the same as PAGE mode?
I'll give it a try tommorrow.

I am using a Digitrax DCS50 to program a TCS CN decoder in PAGE mode. CV5 always reads whatever I put in CV1 (Loco #). I can try to overwrite it with another value but it still comes back with the Loco #. Change CV1 to another value and CV5 reads that new value.
Is this a bad decoder or am I missing something?
