I have had one defective DH121 (black line) replaced without fuss by

Digitrax, and am now facing installing several others (no black line)

that have been in inventory for some time. If these decoders pass the

Test (Loy's decoder testing), are these OK, or do some (all) of the

defective ones slip through to create problems later?

There have been various posts detailing the somewhat unreliability of

simply looking for the "black line" on a DH121. While that was initially

suppose to indicate a "good" DH21, other posters have suggested that the

rule is no longer valid. However, if you have had them for the same period

of time, I would be very suspect. I had 7 DH121's that passed Loy's decoder

tests but did NOT work correctly almost immediately (2 decoders) or after

several weeks (5 decoders). I would not chance the installation and would

just send them back to Georgia with a note.

I agree with Jim. But even the new ones may have a flashing light

problem. The cure is to change CV61 to x40 (that's a hex setting).

Denny,

I've seen the concern from other list users about the DH121. I

myself have had the problem with 6 of the decoders. The simple fix I

found was to just reprogram the address of 03 into the decoder. Even

fresh out of the bag, it will read back 03 on the address, but it

won't work. Once I programmed 03 in to the address, they all worked

fine. You might want to try this approach before sending them back.
