7: Configuring the MP Modem to Report GPS and I/O Data • I/O device installation The MP modem is capable of reporting position and heading information using the embedded GPS module, as well as the and configuration status of sensors, gauges, and alarms connected to the I/O (Input/Output) port. The MP modem is typically installed in a fleet of vehicles with the GPS and/or I/O data being sent to a central office or dispatch for processing. This chapter describes how to implement local reporting of GPS and I/O data. Chapter 8 describes how to configure your MP modem to exchange data with your private network. GPS configuration and reporting GPS receivers use an array of orbiting satellites operated by the United States Department of Defense to triangulate their coordinates on the Earth’s surface. In order to use the GPS module in the MP modem, a GPS antenna must be connected to the MP modem. (The installation requires either two antennas—one Main RF and one GPS—or a single combination RF/GPS antenna.)

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 7-3: Wiring for using Pin 3 (digital output) as an electronic switch. Pin 10 is Ground.
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 7-4: 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 ...

8: Sending Data to Your Network Application • Retrieve the Unique This chapter discusses how to configure the MP modem to send GPS and I/O data to a network server. This is a simple Mobile Device ID process, but if there are any firewalls on your network or your service provider’s network, the data must be routed through or around the firewall. A general discussion of some methods of dealing with firewalls is provided. This chapter also explains how to retrieve the Unique Mobile Device ID from the MP modem. This is the number that uniquely identifies each MP modem. Any application that uses the GPS and I/O data from the MP modem requires this number. Configure the MP modem to route data to a server The protocol that defines how MP modem data is packaged is Note: For a full list of AT called MTP (Monitoring and Tracking Protocol). You can ...

MP881W Modem User Guide The fast rate timer only becomes active when an alarm condition is triggered by a rise or drop in the level of one of the digital I/O channels. The default for the fast rate timer is three seconds. Note: When the fast rate timer is set to 0, a single report is sent when an I/O alarm is triggered. If the GPS timer is set to a value other than 0, it controls the frequency of reports in the absence of any alarm or event triggers. (However, if the GPS timer is set to a longer interval than the low rate timer, the value for the low rate timer will determine report frequency.)
