Multi-Code:

Multi-Code receivers operate on 300Mhz and program with 10 Dipswitches.

There are lots of these Multi-Code external receivers out there mounted on some of the much older garage door openers (gdo) that were built when DIPswitch programming was the most secure method available. the receivers have three prongs that attach directly to three of the terminals on the gdo. This makes a nice neat installation, and works fine on those gdo's that have their terminals arranged in the same order that they are on the receiver. On some of the later machines, the terminal assignment has been reversed or altered so the receiver terminals do not align operationally with those on the gdo , and negates the ability to attach the receiver directly to the machine. This requires the separate purchase of a 'terminal adapter kit'. The leads, however, are long enough to allow the receiver to be mounted on the ceiling near the gdo.

Programming is simple. Just remove the small hatch on the front of the receiver to set or note the DIPswitch code. On the remote, slide down the batter cover to expose the dipswitches, and match to the settings on the receiver. Note that on the switch, "OPEN" means "OFF", so if the rocker switch is tipped down toward the number side, that means that switch is in the "on" position. If it is down towards the OPEN side, that switch is OFF.
