Were you ever able to get this to work? I bought a house a year ago with the same panel and trying to decide what I am going to do with mine. Thanks

I never did get the DSC 2550 to work. I agree that it is probably incompatible. I upgraded and got a DSC 1864 (I think), and this works flawlessly with alarmdecoder. I got the board for less than $180 and it works with all of the pre-installed sensors.
