I/O device installation and configuration
The I/O port on the MP modem allows for remote monitoring of gauges, sensors,
and alarms. You can use this feature to display readings from instruments or
gauges and to remotely monitor panic buttons or alarms.
The MP modem’s I/O port is a standard female DB15HD connector for remote
monitoring of gauges, sensors, and alarms. If you are planning to use these
devices, you need to create a custom I/O cable.
This section describes how to connect and configure these I/O devices to work
with the MP modem.
Connecting these devices requires that you make a customized I/O cable. The
cable must have, at one end, whatever connector is required by the I/O device,
and at the other end, the High Density DB15 connector. The cable wires must pin
to the appropriate pin numbers on the I/O connector. The pinouts are described in
the next section.
The maximum length of the I/O cable is 15 feet.
Before using the digital input/output lines, you must configure them as inputs or
outputs.
