Wiring the R4222 Photo Eyes to Gate Operators
Compatible with Mighty Mule®Gate Openers
1. Connect the () Terminals of the TRANSMITTER and RECEIVER to the POSITIVE terminal of
battery with wire. Alternatively (not displayed below), 1 from the transmitter's terminal can also
be directly connected to 1 on the receiver's terminal as long as the transmitter or receiver's
terminal 1 is also connected to battery's positive terminal.
2. Connect the () Terminals of the TRANSMITTER and RECEIVER to the NEGATIVE terminal of
battery with wire. Alternatively (not displayed below), 2 from the transmitter's terminal can also
be directly connected to 2 on the receiver's terminal as long as the transmitter or receiver's
terminal 2 is also connected to battery's negative terminal.
3. Connect the () Terminal of the RECEIVER to the COM/COMMON terminal of your gate
opener control board with wire.
4. Connect the () Terminal of the RECEIVER to the SAFETY terminal of your gate opener control
board with wire.
