AMX Setting the IR Validation Level, Receiver IR validation level, Sensor IR validation level

Wiring and Installation

FIG. 12 DIP switch values and quick reference

As an example, the DIP switch in FIG. 12 defines device number 129 (1+128=129).

If you later change the device number, remove and reconnect the AXlink connector. This enters the new device number into memory.

The device number takes effect only on power-up.

Setting the IR Validation Level

An IR transmitter must send repetitions of data for the receiver to accept it as valid data. In some installations, a light wall color or other physical condition may interfere with the sensor's or receiver's ability to sense the transmitted signal. The signal may reflect or bounce and become distorted. The receivers can be set to use either two or three repetitions of sequential signals to validate and accept the signal data.

Receiver IR validation level

Perform the following steps to set the receiver's IR level.

1.Locate jumper pins J1 on the circuit board (FIG. 13).

2.Position the IR validation jumper (Figure 9) to select the number of valid IR data repetitions to be accepted:

!Position the jumper at 2 to have the unit validate two sequential signals.

!Position the jumper at 3 to have the unit validate three sequential signals.

3.Go on to Installation.

Sensor IR validation level

For the sensors, this IR validation level is set on the receiving device (such as an AXC-RCVI). Refer to the instruction manuals for the receiving device for more information.
