I/O device installation and
configuration

Jan.05

The I/O port on the MP 555 GPS modem allows for the remote
monitoring of gauges, sensors, and alarms. This feature can be
used to display readings on instruments or gauges and to
remotely monitor panic buttons or alarms (such as gun rack
alarms that are trigged whenever a gun rack is opened).

This section describes how to connect and configure I/O
devices, such as sensors, gauges, and alarms to work with the
MP 555 GPS modem.
