2.1 LED Indicators<br />
The three LED indicators are designed for low power consumption so remain in off-state except when particular<br />
functions are active or require attention.<br />
MODEM<br />
When on, modem is active.<br />
DATA/RSSI<br />
When on, data is being transmitted.<br />
STATUS<br />
The status LED indicates the current condition of the datalogger module. General behaviour is that this LED<br />
flashes once each scan cycle, while the scan is executing, although the Status LED can be disabled through the use<br />
of the ScanLEDOff program instruction. If a fast flash of 2 flashes each scan interval is occurring, then a diagnostic<br />
trap code may be read for further instruction. This may indicate memory failure.<br />
