Power Modes and Information
The PinPoint‐E can be configured to switch power modes in
response to specific events, such as when the voltage to the
modem drops below a configured threshold or when the DTR
changes, in order to conserve a vehicleʹs battery life. The stand‐
by state, low‐power mode, will prevent the modem from
draining the battery while allowing the modem to quickly
power up to regular operation when it is needed.
Tip: If you want to use Low Power Mode, you should choose either
voltage level or DTR/RTS as the trigger, not both.
You can configure Low Power mode using AceManager.
