Page 40: Switching The Modem On/Off
ZETA Series GPRS/UMTS/LTE Terminal with GPIO Switching the Modem ON/OFF Power on the ZETA The ZETA modems have several options to power on. The 2 main options are shown below: 1) Auto power up using the built in CPLD power controller. This process is controlled by default within the modem to control the modem functionality and allows for automatic power up when power is supplied. - Page 41 ZETA Series GPRS/UMTS/LTE Terminal with GPIO Considerations when manually powering the ZETA on and off The PWRON_IN and PWROFF_IN signals requires a positive “edge” (a “sharp” signal transition from low to high) to turn the modem on. This transition should be a rising signal from 0V (GND) up to Vcc (max 42V), or at least a large fraction of that voltage range (>0.5V).
