Right Nigel, it encodes a few switch inputs to some signal it sends over the air and then decodes it to like signals on the other... It's an encoder/decoder, whos use happens to be remote control. It being a remote control doesn't preclude it from being an encoder/decoder pair so I'm not sure exactly where your logic is coming from. That's like saying a car doesn't have wheels because it's a car.
And no offense to Mr CCE, but it's not the company that's at fault, Mr CCE didn't understand what he was buying or what else might be available. It's serviceable for his needs if his needs are minimal. Assuming such a chip will provide minimal/low error rates is however a horrible idea. You have to have software to back up the hardware or it'll never be reliable. No RF link can EVER be completely reliable.
No offense taken friend, but the thing is, I didn't just go out and start asking about what I need for my situation, the person who recommended these codec pairs (and I insist on using the word "codec") is someone who didn't start working with electronics/mcu's/digital communication just yesterday, but has been doing so for years, his experience and his very successful company are there to prove it.
Nigel, I'm gonna have to go with Mr CCE, as long as the frequency he's feeding those remote control lines is substantially less than the overall frequency window it'd be easier to interface to than some more purpose built RF modules, he's got access to an entire nibbles worth of data at one go.
Nigel, because said 'remote control' IC probably costs a few dimes. The only refrence I was able to find for the module you linked was 12 dollars each!
Why are you arguing this so steadfastly? If it works in his application which he's stated thus far that it does then you're just straight up wrong I'm sorry. How are you so sure you know a 'suitable device' when you don't even know his data requirements are in the first place?
Mr CCE wasn't looking for a lecture or the best possible components to use in an RF link, he was looking for how to use what he had in his application, yet you're hounding him to the ends of the earth over the use of a particular chip in an application that you know NOTHING about! He only came here asking for interfacing advice.
