Configuring the MP Modem to Report GPS and I/O

Data

Typically an analog input device should be connected between

Ground (pin 10) and the input port (Pin 7, 8, 14, or 15).

Figure 6-4: A sensor wired to Pin 7 (analog input) and Pin 10 (Ground).

The analog input ports use a 10‐bit (1024‐step) analog‐to‐ digital converter over a range from 0 to 3.45 VDC, yielding a digital step resolution of 0.0032 V.

Example: analog sensor connections

An I/O cable for an analog sensor requires a wire to one of the analog input pins (such as #7) and one wire to the Ground pin (#10).

I/O configuration using AT or 3G Watcher commands

Once a sensor, gauge, button, or switch is physically connected to the MP modem, the MP modem must be configured to manage the input from, or output to, the device. This configu‐ ration can be done using either AT commands or using 3G Watcher.

For a list of AT commands, please see the MP 3G Modems AT

Command Reference manual (document #2130810).

There are separate windows in 3G Watcher for configuring the analog and digital ports.
