The sensors may be turned off.
Check the sensor power supplies.
The sensor station numbers may be not correct.
Check the sensor station numbers.
Sensors may have malfunctioned.
Change the sensors.
Check that the packet filtering function’s enabled/disabled state in Protocol setup are
matched between the coordinator and routers.
If the packet filtering function is enabled in the coordinator’s Protocol setup, the
timeout value may not be appropriate.
Set the timeout value to a value obtained by subtracting the fixed overhead (1
second) from the filter timeout on polling of the host device (e.g., logger).
The filter timeout on polling of the host device (e.g., logger) may be too short.
Tune the filter timeout on polling by considering the time required in the wireless
segment (roundtrip).
See section 5.4.5, “Monitoring Unit Time of Radio Transmission.”
If the packet filtering function is enabled in the router’s Protocol setup, the timeout
value may not be appropriate.
Set the timeout value longer than the time required for data to be transmitted from the
router’s sensors to the router.
