• Capturing External
Events using Inputs
• Power Modes and
Information
The PinPoint‐E has special features for use in a mobile
environment. The PinPoint‐E can be configured to monitor the
inputs and respond to specific types of events. The PinPoint‐E
can also be configured to change its power mode in order to
conserve power. These features can be configured to your
needs.
Capturing External Events using
Inputs
The RS232 DB9 interface (the serial port) on the PinPoint‐E can
be connected to digital switches and configured to capture
contact closures using RTS and DTR to signal external or
physical events, such as a tow bar being activated, opening a
door or trunk, the car is turned on or off, etc.
Configuring the DTR and/or RTS
Monitoring
You can use either AceManager or a terminal application to
configure the modem. In AceManager, select PinPoint from the
menu on the left. Scroll down the command options until you
see RTSI and DTRI.
