Wow, ok I give up...

Is this jack for a unique Meridian Infra-red eye like the manual says or is this some form of std input? It does not conform to the normal input standards. Tip +12 ring? Sleeve?

If I try the normal method of a 3 pin I end up with 12V that’s tip - ring with ring being gnd. The only way I don't get 12 V is ring - sleeve and that does not work sending IR from Crestron.

So. I give up. Anyone used this jack to control it from Crestron or other automation?

This is the std Xantech pinout.



Also I assume I can just use 861 IR codes?

If you are using Crestron use RS-232. Very simple protocol

RS232 is great for input selection. Volume is smoothest via IR. The repeat rate via RS232 makes for slow control.

AND RS232 has had issues over a long time where it will just stop working and you need to power cycle a 861 to get it back.

IR is THE most stable protocol. RS232 is simply more to go wrong.

And IR should work. I don't see how to do it. Maybe I need to buy a "Meridian Infra-red eye"?

Sorry for too many posts. I had to go look. There is no RS232 port on a 271, it's IP control or IR. IP Control is also slow doing volume. IR is best.

The Meridian wiring is not the same as Xantech.

Tip is +12v
Sleeve is IR input
Case is ground.

This is shown in the 251 user manual on page 19.

Having said that I was just about to post that I am trying to use IR with a 218 using a Xantech without any success. I have enabled the IR port in the configuration program. Some input keys on the MSR+ work but all the others do not.

Any help would be appreciated.

Yea I had figured out the likely pinout but none of the 861 IR codes were working.

Well this is good info tho. I will hook this up this way and then work on codes that might work. I want input source selection, power on and off and volume.

What IP control documentation is out there ? Are the IP controls the same for all devices ?

So I can't find the IP control protocol document anyplace. Why is this so secret?

Looks like TCP but I can't find the port number? Maybe a example of the string, like $VDN zone?

It's insane that TechNote_TN78_Sooloos_Control_API document leaves out protocol and port.

I need the above document for a 271 if anyone has one. Mostly I need the TCP Port number and I might be able to guess from there.

Why does Meridian not publish this info?

If you really need to use IR then use the Meridian G12 and a IR flasher. The IP Protocol is the same as the RS232 protocol. You need the port number and the IP address of the 271 to enter into a TCP/IP client module in your Cestron program.

Volume ramping speed can be adjusted using an oscillator symbol. I have never had issues with volume ramp speed or reliability of RS232 control. I have also built RS232 control modules with feedback for bass, treble, etc. for the processors such as the 861 and G series.

I will get back with you about the port number.

The pinout of the “IR In” connector is as follows:

Tip: +12v DC
Ring: Sensor Output
Sleeve: Ground

This also applies to the 251 and 218's running build 185 firmware.
