About this task

The FX-WRZ7860 Receiver requires a unique RF address to communicate with associated FX-WRZ Series Sensors. Set the RF address for the receiver by positioning the numbered switches on the TRANSMITTER ID address DIP switch block and the AREA address DIP switch block. See Radio Frequency Addresses for One-to-One Wireless Sensing Applications for more information.

To manually set the FX-WRZ7860 Receiver RF address:


  1. Disconnect the power to the SA Bus.
  2. Set the numbered switches on the TRANSMITTER ID address DIP switch block and the AREA address DIP switch block to the desired RF address (Figure 5).
    Note: To use an FX-ZFR or FX-ZFR Pro Series Field Bus Router, set all the AREA DIP switches on the FX-WRZ7860 to the OFF (0) position. (The AREA DIP switch is not used on the FX-ZFR or FX-ZFR Pro Series.) In addition, set the most significant bit of the TRANSMITTER ID to the OFF position on both the FX-WRZ7860 and FX-ZFR Series. 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.

  3. Check the AREA DIP switch block on the back of the associated sensor and be sure that the POWER switch is set in the OFF position (Figure 8). See Setting the FX-WRZ Series Sensor RF Address for more information.
  4. Connect the SA Bus to the FX-WRZ7860 Receiver.
  5. Set the sensor’s controller POWER switch to the ON position.

    Five seconds after the power is applied, the red LED flashes to indicate the firmware revision. For example, firmware revision 3 is indicated by the LED flashing three times during the startup process.

  6. Repeat this procedure for each receiver in your application.
    Note: Do not create duplicate addresses on any of the receivers at your job site. Duplicate addresses can cause a variety of problems in One-to-One Wireless Sensing applications.
