2gig GDR1 Not-So-Universal Garage Door Opener Options

[vicpylon]

Sorry if this is the wrong forum, but I needed to get this information out to the community to see if anyone has a solution.

I bought a 2gig GDR1 Universal Garage Door Opener to use it with my 2gig alarm panel keyfob aux button to open/close my garage door. I cannot get it to work, but I fairly certain I know why it does not work and if I am correct the "universal" needs to be removed from the product description. The unit plugs in and connects to your existing wiring, either directly into the garage door motor on the ceiling or wires into the wall button. When activated it makes a momentary connection break and this is supposed to signal the garage door to open/close.

Interlude: The package says that only the 2gig-key2-345 keyfob will work with this unit. I have 2gig-key1-345 fobs, so I ordered new units that have not arrived yet. Just for kicks I tried the aux button on the key1 and successfully programmed the GDR1 unit to accept the signal. A meter and my ear (you hear a click) indicated that the circuit is broken when I hit the keyfob aux button. There is slight possibility that this is the reason the unit is not working, but I doubt it because of how my garage door wall button works. Regardless I have the supported (in the manual anyway) fobs coming in a couple of days and will update the post when I try the GDR with them.

I am skeptical the new fobs will make a difference because I have a new (less than 6 months old) Genie SilentMax 1000 garage door opener. The wall panel has three buttons, one to open/close the door, one to turn on the lights and one to lock the garage door from opening... and only two wires with 14 volts on them. Do you see the issue? In order for two wires to control multiple operations the wall panel (which has a little circuit board in it) is sending some sort of code, whether it be some communication protocol or just opening/closing the circuit in a specific pattern to tell the motor what to do. The GDR1 does not appear to send any code, just cut the circuit for a moment. As an experiment I tried simply shorting the wires coming from the garage door to the wall button and the door did not open. After the test I am now assuming that the GDR1 cannot handle my door opener.

If I am correct then this unit is far from universal. Any thoughts? I am dropping a line with this information to 2gig as well. Perhaps they have an idea.
