While this is differential, it does not properly utilize the twisted pairs in the cable. You will need to customize the wiring on the transport end to work correctly.

thanks Brian....might have to put this in the too hard basket...spdif looks good again

All you need is an RJ45 crimped. If cables for this kind of application are something people could use, I could certainly stock different types.

Hhhhmmmm, I have plenty of ethernet cables laying around ( those yellow and blue ones with rj45 plugs on both ends).
I was hoping just to cut the plug off the recieving end and wire directly to the teleporter in the correct fashion.Can you do it same as in say a pre amp with balanced out puts and only take the + to use for single ended ?
thanks again

So are you saying that a cat 5 or 6 cable with rj45 plugs on either end but wired for their tx or rx end connection?....I think you said to swizzle the cable to suit

Can you show me the pinout for the teleporter rx end now that you have shown me the Lite cd21 i2s pinout

I will have a crack at making up a suitable cable..or maybe it would be easier to purchase one from yourself...if you would make one up for me

The mapping is here:

Introducing the bit "Teleporter"

RJ45 Pin : LVDS Signal

1 : B0
2 : A0
3 : B2
4 : B1
5 : A1
6 : A2
7 : B3
8 : A3

Note that the pairs Ax/Bx use the proper pin mappings to utilize the twisted pairs properly (namely, pins 3 and 6 are a pair, but non-sequential at the connector).

Which signal you use with which position is up to you. The goal of the cable will be to get the improperly pairs wires to the proper mapping right at the source connector.

Ok, thanks Brian...will try over the next week

Any news on the manual for the Teleporter Russ ??

Cool, thanks ichiban

It's enough +4,83V to power the Teleporter?
