Information from http://www.rfcontrolsystem.com This 4 channel rf wireless remote control duplicator is for cars, garage doors, gate doors, alarm systems, etc. It is a fixed frequency remote cloner (315/433MHz) for copying most common fixed and learning code remote controls. Clone up to 4 remote signals from 4 different remotes. You can use it to duplicate your existing remote controllers so you always have a backup. The remote distance is 50m (150ft) theoretically. With this remote cloner you can clone most common fixed and learning code remote controls with IC such as 2262, 2260, 5026-1, 5026-2, 5026-3, 5026-4, FP527, SMC918, PT2240, EV1527, HT12D, HT12E, etc. But it cannot clone rolling code remote controls with IC such as HCS300, HCS301. Oscillating resistance is no need to be considered cause it is compatible with the oscillating resistance automatically. Look at the following operation, you can easily work with it. 1. Clear out the original code (...
