Using the IR receiver in Met6N

xnet111xnet111 Junior MemberPosts: 6
Hi

I'm puzzled by the IR receiver in the Met6N keypad. Can anyone tell me how to program for it ? I'm guessing that buttons pressed on a remote aimed at the Met6 will turn specific channels on/off on the device port ? I've tried several different remotes but none of them seem to cause any output from the Met6 but I'm not sure if that is because its unable to read the remotes I'm using or there is something I need to do in code to read them (I thought I would see channel on/off in the Notifications window)
I'd be very grateful for some guidance on this.

    Someone can correct me if I'm wrong, but...

    I believe you're looking for a product that no longer exists. All AMX remotes that operate in the compatible 38 kHz range have been discontinued.

    While AMX no longer makes the IR remotes, the usefulness continues as long as programmable remotes are common.

    There are 256 AMX IR codes... each, when seen by an AMX receiver, causes the code number to arrive as a PUSH from the pickup as a UI device.
    ONLY AMX codes will be detected by the Met6N, or by any AMX IR receiver.

    In the attached ZIP file are many helps for you. It includes all 256 codes as text HEX codes for use with most programmable remotes. It also includes them again as IRL files, both of these in both frequencies, plus several conversion utilities.

    Thank you

    Thank you very much John both for your explanation and your attachment. That has made it all perfectly clear
    Cheers

    Still having trouble

    Hi again

    Armed with the codes from John, I loaded them into an IR sender but I'm still getting nothing out of the met6. I'm sure that my sender is working because if I load up other IR codes (from other remotes) and point it at the relevant device, the IR control works fine, so I have some confidence in the hardware. The met6 IR device 129:1:0 is showing as online. Am I missing something ? Is there some way to prove that the receiver in the Met6 is operating ?

    That also leads me to another question in regard to the hex codes vs the AMX IR files. If I import one of the ascii hex codes into IR Edit (e.g. Channel 2) it gives slightly different values for the modulation frequency and pulse lengths than the irl file does. (e.g. importing the hex for channel 2 shows a modulation frequency of 39Khz (38Khz from the irl file) which leads to the pulse lengths all being slightly different. It doesn't look to me as if this difference is enough to matter but I'm curious as to why. Is it because the hex format is based on pronto which takes its modulation frequency divisor (second hex word) based on the internal pronto clock of 4,145,146 Hz and the AMX irl format assumes a different internal clock (and therefore a different divisor for a given modulation frequency ?

    Any suggestions very gratefully received.

    Cheers

    While I'm sure what John sent is fine, here's another file to try. (Just in case something is goofy.) it's a .ccf file of the 255 AMX IR codes.

    Several things...
    1. IF you have changed the buttons or opened the unit, on reassembly you must carefully guide the black paper shield into the space above the LED window in the body. It will try to flap down and then will BLOCK the IR pickup when assembled.

    2. Note that the IR uses one address higher than the Keypad (and the address you set). So if you address the unit at 60 on axlink, button presses will carry the 60 address, but the IR will use 61. BOTH will appear in your NetLinx device tree.

    3. Be sure you see your keypad/IR on the device tree at the address you expected! Note that the "DIPSWITCH" tool in Studio and the standalone may lead you to adjust the switches UPSIDE DOWN due to the labeling of the tiny switch in the MET. This will result in a wholly different address than you thought you set.

    4. Turn on the diagnostics at the bottom of STUDIO, so you can see "press" events. There you will see any UI event at any address, including any IR being noted... regardless of what your code may be expecting to watch. This will tell you a lot.

    5. The variances in frequency make little difference, and the ones in my kit are as supplied by AMX remotes, RIP. Every one of them is tested to work and are in use in hundreds of our systems.

    6. You didn't mention what you are loading the IR into, but nearly anything that accepts HEX style IR will work. Has worked. Might work. We've had a few sites claim that the URC's deliver the code "sluggishly", or that they have to hold the button down for a second to make it work. This has been rare and might be due to settings in the remote itself (repeat rate, etc.).

    7. There is no seventh thing. Maybe.

    Hi John

    Thanks again (and apologies for the long delay in replying - I got distracted on to other things !. I'll work through your list and report back (hopefully with success !!)

    Cheers

    thread resurrection!!

    John,

    I'm up against a similar problem - user wants to control keypad from their bed. Have you had to do any of these lately? I was hoping to load the codes onto either a Logitech Harmony or Dish remote and wondering if you had tried on those before.

    Many thanks!

    We have not used a Dish remote (I was unaware it accepted learning or uploaded codes), and the Harmony's are exceptionally unpleasant to program. But if the hardware allows intake of HEX codes, there should be every expectation of success.

    Well, that is until I see now that the MET6n is discontinued by AMX. Along with any mention of engraving services anymore. This is particularly distressing as now AMX has no Netlinx-series KEYPADS nor IR PICKUP devices for sale. Which just about ends the product line for versatile control use... Even more emphatically than having no handheld remote and no wireless panels. At least we still have TPControl. I hope.

    EXB-MP1 has an IR Receive port as do the TX and RX DX boxes.

    So it does. And the accessory "IR03" pickup used by these is NOT marked discontinued, though they are listed as being for the UDM modules..
    Sadly, this will NOT work on the NI700/900 (also discontinued, they want the discontinued IRX-PP38) and the new NX processors (available!) don't say what they would use for IR pickup.

    A limited choice is better than none at all.

    We have maybe 50 of the (discontinued) swivel-mount Axlink IR pickups if anyone is in a real bind.

    According to Harmon Support today, they still make custom engraved buttons for the MET keypads. The ordering app is online, a FLASH app, on the KEYPADS main page in PRODUCTS... on the right-side banner.

    Now I see AMX has a new MET-6nE (announced? available?) in the product pages, and similar versions replacing the other models. These are ETHERNET instead of AXLINK. There are also EXPANSION versions that daisy-chain up to two more keypads from the one with Ethernet. Or there was going to be. The expansion versions now are marked DISCONTINUED, So IF you wanted a gang of three, you'll need THREE cat5's to the bunch. Handy.

    Lest I gripe too much, hurray for keypads back in the catalog. yay.

    They don?t show any remote controls and under environmental controls they only show the flush lutron temperature sensor but why list a temp sensor when they don?t list thermostatsor or anything else.
