--> XDP4000X-List message posted by: Ethan <telmnstr@757.org>
Anyone know of any CDX-828 or other Sony digital Unilink changers for sale
cheap? My attempts at getting the ?CDX-725? firmware to trigger the 210EQ
to go digital didn't go so well. Then a friend stepped on one of the
boards from my CDX-725 and cracked it. Ooops.
My only real goal is to capture the unilink traffic so I can make the open
source GNUnilink adaptor tell the 210EQ that it's digital, so I can use a
DVD player's digital output with the 210EQ.
Granted, I could just buy a better DVD player that has quality analog
outputs, but no adventure in that.

Ethan,
Below is a code snippet from my 8051 controller-based Full Unilink Slave Emulation.
In it, you will find all the great mysteries of proper Unilink initialization.
Basically, there is a single bit in one of the init bytes that signals
the head unit whether the input will be analog or digital. This is commented
well in my code below. I also included a couple of other nifty things that make
my Unilink emulation 100% Sony compatible such as the Slave Break device calculation.
Party on,
Matt Dralle
