NI_900 IR/RX Port?

vining

Has any one used this? I can't seem to find any documentation on what this actually can or can not do. Is this strictly a repeater, IR in gets passed to the IR/Serial ports or can it do tricks? Like compare received IR strings and compare them to stored IR values and if it matches do something. I know that's probably asking for too much but that would be so nice to be able to make every ones favorite cable remote do basic system control. Power up, change channels and AVR volume control instead of TV volume control. I currently use the cable remote to power up the system by using a current sensor on the TV so when the TV powers on it turns the system on (watch cable mode) and then you just change channels. Works great for kids to keep them away from the MVPs but I can't change the volume w/ it. I've thought of trying the Xanteh IR to rs232 box but I believe that just works on Xantechs RC88 codes or something to that affect. Any thoughts? Any know what this IR receive port can do?

The IR RX port (in conjunction with an AMX IR receiver) only recognizes AMX IR codes. There are 255 of them. When an AMX IR code is received it generates a BUTTON_EVENT with a PUSH and RELEASE the same as if it were a TP. For example if the IR RX port (dvIRIn) sees AMX IR code 10 then it generates BUTTON_EVENT[dvIRIn,10] This allows you to turn any Theater Master remote, RTI remote, Pronto remote, or any other learning remote into a one-way AMX interface.

OK, I guess the thinking is if you step up to an NI-X100 you'll likely have a TP or AMX remote and therefore won't need an IR?RX port.

I think it was more like the idea that you could use this to control a small room or a projector area that was part of a larger system, and it could then provide an IR receiver for local control. Your basic boardroom, for example, might have a projector or a monitor, and a DVD player; an NI-900 or 700 would be perfect to control the minimal amount of equipment, and you just tack on an IR remote to control it.

So the IR/RX port slots come pre loaded w/ 255 AMX IR code (IR 1 - IR 255) in them but it would be nice if it were possibe to load your own IR into the slots. Then you could use a standard cable remote to do your basic system control. System power on/off, cable channel changing (which it does anyway) and system volume up/down by adding any cable remote supported TV code to a IR/RX port slot so when the port recieves the volume IR signal, the port matches it to the stored slot and takes what ever action you define in code just like it does with an AMX IR code match. You know you can store what ever IR file you want in the slots it's just a matter of whether AMX will let you.

From a sales perspective on the one hand AMX might be able to sell more NI-900s but on the other hand they might sell less Remotes and TPs. They probably make more on the latter.
