Elk M1 Serial Connection

[KidCalledZero]

I have a Lutron RadioRa Chronos controller which is connected via serial to my home theater controller. This allows me to dim lights with my TV remote.

I am installing my M1 system and want to tie the M1 into the Chronos with a serial connection using a ELK-M1XSP but I also want to keep the connection to the home theater controller. The Chronos only has one serial connection.

Is it possible to install two ELK-M1XSPs, one for the connection from the M1 to the Chronos and one from the home theater controller to the M1? I would then need the M1 to pass through the commands received from the home theater controller to the Chronos.

Is this possible?

Thanks

I suppose you could write rules like below for each command

WHENEVER THE FOLLOWING TEXT IS RECEIVED "xxx" THROUGH PORT x
THEN Turn light x on

But there are a lot of assumptions in this:
You would need to hard code all the text strings in the M1.
The Chronos Protocol would need to be ASCII
There can't be any setup sequence, etc when the two connect. Just the raw commands are coming in

So the answer is maybe, but it is probably gonna be complicated. And I can't remember what the limit on texts are in the M1. You might want to alternatively consider a different HT controller that supports the M1 natively. Then let the M1 control your lighting.

I was hoping I could just write a rule that passes every string received from the HT controller directly to the Chronos as the same string. The HT controller would be sending the RadioRa command strings and all the M1 would do is relay it to the Chronos. The strings would be meaningless to the M1.

There would only be about 10 different strings coming from the HT controller.

I have not attempted to program my M1 yet so this may be ignorance speaking but cant you write a rule like:

WHENEVER THE FOLLOWING TEXT IS RECEIVED "Text String Command" THROUGH PORT x
THEN......send "Text String Command(same as above)" to.....(chronos).

Well, I think that is possible in theory - as long as you're sure there's only a few commands... because you'd have to write a rule for every single command. What you're proposing above actually sounds correct - watch for a given text string - and when you see it, send it on another xsp/port.

In the "old days' we would solve this with a RS232 serial merge device, taking inputs from the M1 and home theater system, and merged output to Chronos. I'm not sure if anybody makes these today. Not difficult to do with a chip or a couple of transistors, if you're handy with these.
