Channel Three negative (-) output: A negative (-) output will be supplied whenever the code controlling

Channel Three is received.

IIMMPPOORRTTAANNTT!!

The Channel Two and Three Mini-Harness outputs are all 200mA capable and should not

be used to drive anything other than a relay or to supply a signal to a module (551T, 529T, 530T,

etc.). If the RED wire is used to power anything other than the coil of a relay, the module will be

damaged.

NNOOTTEE::

If the unit is being used as a garage door interface, these outputs can be used in conjunc-

tion with a relay to control a second garage door opener. If the unit is being used in a vehicle,

these outputs can trigger a 551T, or any other low current application.

Operational settings can be changed by cutting jumper wires on the circuit board. To access these jumpers,

remove the four screws on the back of the unit and open the module to expose the circuit board. The individual

jumper wires are clearly labeled on the circuit board.

Uncut (default): Pulsed output

Cut: Validity output

In the factory default setting (jumper uncut) the output provided from the on-board relay and the auxiliary

outputs will be a pulsed output when the channel is activated remotely. When the jumper is cut, the outputs

become validity outputs. A validity output will continue as long as the transmission from the remote transmit-

ter continues.

This jumper has no function.

Uncut (default): Code Hopping on

Cut: Code Hopping off

In the factory default setting (jumper uncut), Code Hopping is on. Code Hopping is a feature that uses a math-

ematical formula called an algorithm to change the code each time the transmitter is used. This technology has

been developed to increase the security of the unit. If a transmitter button is pressed while out of range of the

receiver, the receiver may fall out of sync with the transmitter. To resynchronize the unit, press the button on

the transmitter several times within range of the unit. Cutting this jumper disables the Code Hopping feature.

With Code Hopping off, you may notice a slight increase in range.

If no code is programmed into the unit, no output will be supplied. Please refer to the “Programming The System” section of this guide

for details.
