Linear Remotes and Receivers:

Linear makes remote controls for a variety of different garage door openers. They use two different technologies. There are the MegaCode and the "Delta 3" systems. The Delta 3 system uses an eight (8) DIPswitch system transmitting on 310Mhz. All Delta 3 remotes are compatible with all Delta 3 receivers. They are NOT compatible with the Linear MegaCode system.

The Linear Delta 3 receiver is coded by setting the DIPswitches in a 'random' pattern of on and off switch positions. The remote is then programmed to the receiver by putting the 8 DIPswitches in the remote in the same pattern as the receiver. This way, the remote is able to communicate with the receiver, and give it a command to operate the gdo. You can get a variety of Delta 3 remotes and/or receivers from garagedoorsupplyco.com
