Wiring and Installation, Setting the Receive Frequency

Wiring and Installation

Before installing the sensors and receivers, set the receive frequency on the units. On the receivers, the AXD-IR+ and AXR-IRSM+, also set the AXlink device number and IR validation level.

To access the jumper pins or switches on the circuit board assembly in the swivel mount units, separate the housing from the swivel base (see FIG. 8).

On the UniMount units, the AXlink jumpers and switches are on the back of the panel.

Setting the Receive Frequency

Perform the following steps (see FIG. 9) to set the receive frequency:

Sensor circuit board assembly

Receive frequency jumper pins

Receiver circuit board assembly

FIG. 9 Receive frequency jumper pins set at the default setting for receiving 38 kHz

1.Use the set of jumper pins (one set on the sensors and two sets on the receivers-see FIG. 9) on the corner of the circuit boards to set the receive frequency. FIG. 10 illustrates the positioning of the jumpers.

The unit will not operate with one set of pins set for 38 kHz and the other set of pins set for 455 kHz.
