PWRON_IN is the power on signal (pin 4 of the RJ12 power connector). Taking
PWRON_IN high will turn the ZETA-xxP on (assuming there is power applied, but that
the unit has been turned off using PWROFF_IN pin).
During power up, the green and blue LEDs are controlled directly by the ZETA-
xxP power management process, and the red LED is controlled by the embedded
modem module. While the ZETA-xxP is in the powering up process, the Green LED
will flash rapidly (500mS on, 500mS off) and the Blue LED will be off until the power
up process is complete.
ZETA-NLP Variants
After the power on process has completed, the red, green and blue LED’s are
disabled completely to save power whilst it is in an operating state. The green LED
will briefly flash once every 30 seconds to indicate that the modem is on.
ZETA-NSP, ZETA-NEP and ZETA-GEP Variants
After the power on process has completed the red, green and blue LED’s are
controlled directly by the module using the standard set of AT commands described
on

PWROFF_IN is the power off signal on pin 3 of the RJ12 power connector. Taking

when all LEDs will be off. In this state, PWRON_IN may be used to turn the unit on
again.
