All recievers are now Mk3 versions so have IR capability from all recievers in Multidrop.
Difficult to give a definate answer on this as I dont own any Xantech equipment to test against but based on what I have read about Xantech in the past here is my opinion.Also is it possible for me to run a mini jack to mini jack lead from the kat5 unit to an input on my xantech IR control unit for it to then feed to multiple devices?
KAT5 TX outputs IR Data modulated @ 38kHz to directly drive the IR LED. This is a 5v signal with Ground on the sleeve of a mono jack and the active 5v signal on the tip.
Xantech use a strange wiring convention for the IR recievers of
Sleeve = +12V
Ring = Ground
Tip = IR Data
I dont know whether the Xantech IR recievers output modulated IR or Demodulated IR.
If it is Modulated IR then a direct connection *could* be quite simple ...then again not !
What you need to do is measure the voltage on the IR in pin of the Xantech unit with a Xantech receiver connected but NOT receiving IR.
IF the voltage is Zero then it will require a positive voltage to send IR, if the voltage is +5 or +12 then it will require grounding to send IR.
Assuming there is Zero voltage when idle, try feeding +5v into the IR data input via a 1k resistor (for safety) and see if IR is transmitted. If it is you could be in luck.
The next thing to try is a connection between the KAT5 TX and the Xantech input. You will need to make a lead as follows.
KAT5 TX ----------- Xantech Input
MONO -------------- STEREO
Sleeve -------------- RING
I have specified different plugs because the KAT5 unit will accept either but the Xantech must have a stereo plug due to having three connections. Do not insert the lead the wrong way round or you may damage the Xantech as the sleeve of the Mono plug would short the 0V (ring) and +12V (sleeve) connections.
If the "simple" method isnt possible then there are ways around it but they are more complicated.
The three problems you could encounter are......
1. Modulated vs Demodulated IR - can be sorted with a specially programed PIC chip for KAT5 TX
2. Incorrect Logic Level - would require inversion of signal
3. Incorrect Voltage level - would require a level shifter circuit to convert 5v to 12v
It is quite possible that you could encounter at least two of them and possibly all three !!!!
In that case you would have to contact me offlist. If you were in a position to lend me the Xantech kit I could sort it out for you.
Hope that helps
