GSM-5 LED Indicator Readout
External Interfaces - Front Panel
Received Signal Strength Indicator
A stack of 4 green LED’s on the left side of the front panel indicate the relative signal strength of the
cellular radio signal. It is analogous to the ‘bars’ display on a cellular telephone handset.
RSSI Indicator
LED’s ILLUMINATED SIGNAL STRENGTH RSSI (dBm)
4 Excellent -73 or better
3 Good -83 to -74
2 OK -93 to -84
1 Marginal -109 to -94
If no signal is detected, the LED’s on the stack alternately illuminate from bottom to top and back in a
‘scanning’ manner.
GPS Indicator
The bottom (#1 ‘Marginal’) LED on the RSSI indicator will blink several times for 1 second every 10
seconds to indicate a GPS location x is available. This indication is independent of the cellular signal
strength indication.
