FEW CLIPS I FOUND :

As you may be aware, there can be difficulties when using CDJ with
players arranged in master slave configurations. This is due to the
master player overriding CDJ's commands to the slave player on some
occasions, causing it to stop playing or move to another disc.

I have a 270 / 200 combo. If you choose to operate the players in a
master/slave configuration (versus totally independently) you connect
them via an slink cable, the same way you
connect them to the Slink-e. You also route the audio out (analog only,
unfortunately) from the slave player to the audio inputs on the 270
master player. The audio outputs from the
270 then go to your single CD audio input on your receiver (again, only
the analog audio outputs support mixing two players). 

From that point on, the slave player essentially becomes completely
controlled by the master player. When you turn on the master player, it
turns on the slave player. You select CD's
exclusively through the master player; if the disc happens to be in the
slave player, the master player will send the appropriate commands to
play it. All disc text labeling information
and memory is exclusively entered and stored in the master player; it
has memory slots for up to 400 discs. The slave player knows nothing
about this info; it simply deals with disc
numbers sent to it by the master player (invisibly to you, of course,
who simply deals with the disc name on the master player). 

This does present a problem for using these players with CDJ, which
wants to deal with two separate players. Commands from CDJ get
interfered with by commands from the master
player, which also occasionally tells the slave player to stop playing
so it will be in a known state. I solved this by creating a small
circuit (with Colby's help) connected to the
expansion port on the Slink-e that controls a relay. When CDJ starts, it
sends an Slink-e command to open this relay, and when it exits it sends
another command to close the relay.
The relay interrupts a direct slink connection between the two players
when it is open. So, while CDJ is running it sees two independent
players on separate slink busses. Otherwise,
the players are connected together in their normal master/slave
relationship for standalone operation. 

Finally, as for uploading disc/artist/track info from CDJ to a 270, I
don't believe this has yet been accomplished (I think it's one of the
things Colby is investigating). In my case, I used
a computer keyboard attached to the 270 to (tediously) key in all this
info. Since the names in the 270 are all limited to 16 characters, you
have to have intelligent abreviations from full
names anyway, and just truncating full names to 16 characters can be
suboptimal.

***************************************************************************
And and by the emails I have seen in past year from cx270 owner, I would
not touch cx270 with 10 feet pole, there seem to be quite a few "bugs"
in it. It was Sony's first Master/slave experiment and they have learned
A LOT from past mistakes. = now you can use the "master" model as slave
too unlike cx270. 

NOTE !!!! all this is hear say I DO NOT own cx270 (thank god ;) ) all
I'm doing is repeating rumors, see these link's and look in archive

Finally I found it, it was well hidden in www.nirvis.com

Also there are other articles that might be in interest to you :

ie. howto build X-fade mixer, howto get sound from  cdp slave when
master is in pause 


(go www.nirvis.com -> Slink-e -> Technical -> Circuit modifications)

and look in www.nirvis.com  "BBS Archives"
