Description
The MegaCode series of digital receivers are wireless radio controls
designed for use with automatic gate openers or garage door operators.
The MegaCode radio format provides unparalleled security. The transmitter
and receiver can be programmed to more than a million different codes.
MegaCode receivers and transmitters do not contain a typical "coding switch". Each
transmitter is pre-set at the factory to a unique code. The receiver is programmed
by sending a signal to it from the transmitter(s) that are going to be used with it.
This stores the transmitters code into the receiver's memory. The receiver will
retain its memory even without power. The receiver will activate only from these
"memorized" transmitters. Each MegaCode receiver can remember a maximum
of 40 transmitters.
The receivers can operate from 12-30 volts AC or 10.5-30 volts DC and are normally
powered from the gate operator. The relay contact(s) are rated at 5 amps @ 32 volts
AC/DC NEC Class 2 circuit.
STEP 2 Connect receiver to power
Connect the red power input wire to the radio power and the black wire to the common
terminal on the gate operator.
STEP 5 Open receiver case
To open the receiver case, remove the screws, squeeze sides of case and rotate
upward.
