Can I use an additional connecting block from a Xantech IR repeater kit to expand the number of outputs by simply daisy chaining them output to input?
Thanks.
Craig.

You can but you are going to be losing signal on the 2nd IR block. That might be a good thing for devices with really sensitive IR receivers to begin with.
2 better options would be to either replace the existing block with a larger output one. Or split your IR signal before it goes into the IR blocks.

Brad is correct however if you connect via the phoenix plug, Sig/Gnd (only) between the two blocks, and power both blocks independently and you should be OK.

I don't think you'll be okay cascading them. You might be okay paralleling them if the sensor has enough output current to operate all the emitters.
A Xantech distribution block has four circuits. Each circuit places a 470 ohm (IIRC) resistor in series with the LED. So if you take one output from a distribution block and put another block in series with it, then you'll have a sensor output, its current limited by a 460 ohm resistor, feeding a distribution block that will put another 470 ohm resistor in series with the LED.
If you put the blocks in parallel, you won't have that problem.

A good answer is easier with a clear question giving the make and model of everything.

Surprised Ernie didn't point out how he did NOT give us a part number on the connecting block. They have 4 output ones, 6 outputs ones, 10 output ones. And they make some that are amplified.
I think we are all assuming he is using a 789-44. Except Brent seems to be thinking one of the powered blocks, since he mentioned putting power on both blocks. Which is not done if you use 789-44, since those are strictly passive devices. Power is only supplied on those, to pass to the IR receiver.

Yup. I was thinking of the 789-44 (now the 78944). But I was also thinking of the amplified one (one that's got some ten or so outputs) and I was feeling too lazy to look up that part number.
Besides, mentioning that part would not address the subject. The subject was not "is there another product that I don't have that could help me out here." It was "can I use the things I have in a manner different from what the instructions say."
And, oh, yeah, you can mix the four output and the six output ones in the way I described.
