ZETA LED Indicators
There are 3 LED outputs on the ZETA modem that can be configured simply and
easily to indicate the functional/operational state of the modem. This can be done via
software configuration.
The red status LED is driven directly by the GSM engine within the modem to indicate
GSM network registration status. Please refer to
table 3
below for more information.
