RC Switch - Issue receiving data from four button remote

Hi,

I'm having a bit of trouble receiving any signal/data from one type of common keyfob/remote. I've included a photo showing the two remotes I have and the receiver I'm using.

I tested the remotes using the RC Switch simple receive sketch. The remote on the left side of the picture worked great, however, the one on the left didn't work at all.

Is the four button remote shown in the picture (on the right) incompatible with that receiver (Receiver model is MX-RM-5V)? The only other thought I have is that i

Thanks,

In case anyone wants to know where I got these parts:

I bought the two button remote here:

Four button remote here:

And the receiver with transmitter units here:

I decided to test out the receiver that came with the four button remote (It has RO2A printed on one side, chip number is PT2272-M4). It has four digital output pins and another pin VT that acts as an interrupt.

This link was very helpful in setting everything up:

I changed the code to output serial data and everything worked perfectly. Then I changed out the receivers and found that 2 of the 4 could be controlled by just one of the four button remotes. I'm pretty sure that means that two of the four remotes I have are identical (code wise). I guess it's useful if I need two remotes for one project, but also a pain since I couldn't use them on different projects.

I also posted an issue on the rc-switch GitHub repository. I'm hoping that I'll find a more conclusive answer there.

I finally got everything to work perfectly!! I looked through the datasheet for the PT2272-M4 chip and was able to locate the data input DIN pin. I figured it would be worth a shot to hook this pin up to the Arduino and it worked great! The example simple receive demo sketch that comes with the rc-switch library will work with what I did. There's only three wires (ground, vcc, and the DIN pin to Arduino pin #2), so its easy to do.

I've pasted in two photos showing exactly which pin I'm referring to and how I set it all up. I also added a screen shot showing what the data output looks like. This setup is MUCH nicer than running 5 wires for the four pins and the interrupt.

If the image hosting site takes my photos down for some reason I've also attached them to the post. I just want to make sure this information is out there as I'm sure others have had the same problem.
