Sky STB IO-Link pinout

(1/1)

johnkenyon:
I'm looking for a cheap composite to UHF video RF modulator, which can turn a PAL composite video signal into a UK analogue UHF PAL-I signal (sound carrier on 6MHz).

Ebay shows cheap beyond £7-£8 chinese modulators which output at 61.25MHz (aka VHF Channel 3, which in turn indicates NTSC)

The best cheap option seems to be a Sky IO-Link box, which has a 10 pin mini-DIN connector which plugs into a Sky set top box.
The down side is that the IO-Link pinout seems to be either the most closely guarded secret on the internet, or the most ungooglable subject ever.
All searches for "io-link" seem to take you consumer targetted "howtos" or sales info, or an unrelated IEC standard for talking to sensors and actuators.

Does anyone know which pins on this connector present power, audio and composite video to the modulator?
 (or even better has anyone got a full pinout for the connector?)

(Edited: subject changed and the text below added -When you read your post a few hours later and realise that 90% of the readership don't know what "Sky IO-link" is...  :palm: )

The IO-link is a socket on the back of more recent set top satellite TV receiver boxes (STB) issued by Sky TV (at least in the UK, possibly elsewhere where they have the same presence).
This allows the set top box to be shipped without the following hardware:
* One or more RF outputs
* A "magic-eye" receiver, which takes a remote control signal fed back up the co-ax from a remote TV which allows you to control the STB from another room

If you need this functionality, then you buy an IO-Link "box" which has a single cable which plugs into a 10 pin mini-DIN socket.
