Sony UNILINK-cable

[Jørn-E. Årnes]

I want to hook up a Sony CDX-70 Compact Disc Changer to a Sony
XR-7070 Car Stereo, but are missing the UNILINK-cable to connect
these two together (I want to make my own cable that is).

I do have the complete service manuals for the both of them, but
as the line configuration are somewhat confusing, I'm not sure how
to do this correct.

For instance: there are two datalines (in and out) from the Car Stereo,
but the changer only support one (?).

I do believe that these two components should be able to work together.

So, does anyone know the pin assignment for a Sony UNILINK-cable?

Greetings, Jørn

The XR-7070 is pre-Unilink. You need to use a pre-Unilink CD changer
with it. That would be any Sony CD changer with CDX-Axx where the xx is
some number. The main difference is the A in the model #.

A Unilink device uses an 8-pin ISO DIN connector while the old standard
used a 13-pin DIN. The two are incompatible. There once was an adaptor
to use the CDX-A series changers with Unilink stereos, but I don't think
there was ever one to go the other way around.

I have the following pin outs from sony service manual.

pin 1/2 - reset
pin 3 - SIRCS Switch
pin4 -bus Clock
pin5 -bus Data
pin6 -bus On Switch
pin7 -+ Positive (Batt)
pin8 -Ground

Pins 1/2 either pin 1 is connected in the circuit in the radio or otherwise
pin 2 is connected . they are not together.

I think if u make a cord exactly from pin1 to pin1 ,and so on, I think it
should work!

This is the best I can do.

pins are counted looking at the front view of the connector.
Pin 1 starting at bottom right.

--- --- ---
6 5 4
---- ----
8 7
--- --- ---
3 2 1

end.

Does the service manual give any more details as to the function of
each pin or does it just name them? What I'm really after is the
following:

I have a Sony XRC190 (AM/FM Cassette with unilink CD controls) and
want to use the unilink audio in (RCA) jacks for connecting a portable
CD player (no $ for a changer). I think the head unit disables the cd
audio in unless it "sees" a changer connected. Any thoughts on how I
can do want I want? TIA,

Hi Curt,
You are correct.The way they work is that you can't use the input if
nothing is connected to it,ie.a changer,tv tuner,etc.
Hope this helps.

Peace and tunes,
Larry
