GARAGE DOOR MODULE

Installing and setting up the garage door module is easy. When the unit is powered up, it flashes all four LEDs so you know that programming is required. The network number is entered first using S101 to cycle through 1 to 15. The currently selected number is displayed in binary on the four LEDs. When the desired number is reached, S102 enters the selection.

Next, the unit flashes three of the LEDs so that you know to enter the device number. You select the device number the same way you select the network number. After entering the device number, the unit blinks all of the LEDs three times to let you know that programming is complete and the device is going into normal operating mode.

 Device numbers should be unique for each type of sensor, but they don’t have to be unique across all of the sensor types. The garage door sensor should be mounted on the inside of the garage door with the solder side of the Freescale MC13192 SARD PCB facing toward the door. When the door is open and horizontal in the upper track, the component side of the PCB should face downward.
