MP875 Modem User Guide

Digital output devices

Digital output devices are those that have only two states and the state is controlled by a signal from the MP modem. Any device that is to be switched on and off from 3G Watcher would be installed as a digital output device.

A digital output can be connected to two of the pins on the DB15HD connector: Pins 3 and 11. (These can be used for either input or output.)

Note: Before using the input/output lines, you must configure them as inputs or outputs.

Typically a digital output device should be connected between

Ground (pin 10) and the output port (Pin 3 or 11).

Figure 6-3: Wiring for using Pin 3 (digital output) as an electronic switch. Pin 10 is Ground.

The digital I/O ports provide open‐collector output to a maximum of 500 mA.

Analog input devices

Analog input devices are those that generate a signal of varying voltage, based on the state of an instrument or gauge. An example of an analog input device might be a sensor that detects the vehicle’s speed.

An analog input can be connected to four of the pins on the

DB15HD connector: Pins 7, 8, 14, and 15.
