To establish wireless RF associations in One-to-One Wireless Sensing applications, you must assign and configure the same, unique RF address on the FX-WRZ7860 Receiver and the FX-WRZ Series Sensor or sensors associated with that receiver.

The RF address for an FX-WRZ7860 Receiver is configured manually by positioning the numbered switches on the TRANSMITTER ID address DIP switch block and the AREA address DIP switch block on the receiver. See Setting the FX-WRZ7860 Receiver RF Address.

The RF address (TRANSMITTER ID and AREA) for each FX-WRZ Series Sensor associated with an FX-WRZ7860 Receiver must match the receiver RF address. The FX-WRZ Series Sensor’s RF address is configured by positioning the numbered switches on the TRANSMITTER ID DIP switch block and the AREA address DIP switch block on the sensor. See Setting the FX-WRZ Series Sensor RF Address.

The RF TRANSMITTER ID and AREA DIP switch blocks on the sensor and receiver are binary switch blocks. The TRANSMITTER ID switches on each switch block are assigned numbers (1, 2, 4, 8, 16, 32, 64, and 128). The TRANSMITTER ID address is a number from 0 to 255, which is equal to the sum of the numbers of the switches that are in the ON position. As an example, placing Switches 1, 4, 8, and 32 in the ON position establishes a TRANSMITTER ID address of 45 for the device.

The AREA address switches on each switch block are assigned numbers (1, 2, 4, and 8). The AREA address is a number from 0 to 15, which is equal to the sum of the numbers of the switches that are in the ON position. Typically, the AREA address may be used to distinguish different floors, wings, or areas of a building. Together, the TRANSMITTER ID and AREA DIP switches provide 4,096 unique RF addresses.

Note: To use an FX-ZFR18xx Series Wireless Field Bus Router, set all of the AREA DIP switches on the FX-WRZ7860 Receiver to the off (0) position. (The AREA DIP switch is not used on the FX-ZFR18xx Series Wireless Field Bus Router.) In addition, set the most significant bit of the TRANSMITTER ID to the OFF position on both the FX-WRZ7860 Receiver and FX-ZFR18xx Series Wireless Field Bus Router. This setting provides 128 transmitter IDs to use with a repeater. Since these 128 transmitter IDs overlap those of the FX-ZFR or FX-ZFR Pro mesh system, take care to select a TRANSMITTER ID that is not in use in the local area.

In multiple-sensor applications, two or more FX-WRZ Series Wireless Sensors have the same TRANSMITTER ID and AREA addresses, but are distinguished by the SENSOR # selection on the FX-WRZ Series Wireless Sensor. The SENSOR # may be 199, 200, 201, 202, or 203.

If the FX-WRZ7860 Receiver fails to respond to an FX-WRZ Series Wireless Sensor with a matching RF address, the receiver may have already locked onto another sensor with the same RF address. To clear the receiver from an incorrect association, while the receiver has power, momentarily change the receiver’s RF address to a different RF address and then back again to the original RF address.

Never use the same RF address (TRANSMITTER ID and AREA) for two receivers that are in the same building or general location. RF signals can reflect off objects or pass through glass windows, and it is possible for RF signals to travel between buildings or reach receivers several floors away.

Note: In single-sensor and multiple-sensor applications, a One-to-One Wireless sensing system interfaces with only one supported controller. Since the FX-WRZ7860 Receiver and FX-WRZ Series Sensor combination effectively replaces a network sensor, the same controller applications where a network sensor would otherwise be used are supported.
