RUT955 GPS

The information in this page is updated in accordance with firmware version RUT9XX_R_00.06.09.5.

Summary

The Global Positioning System (GPS) is a space-based radionavigation system. This page is an overview of the GPS service in RUT955 routers.

Map

The Map page displays the device's current coordinates and position on the map. To see the device's location on the map, make sure to attach the GPS antenna on the router and enable GPS in the General page.

The figure below is an example of the Map page:

General

The General section is used to enable the GPS service and the support for different types satellites. Once you turn on GPS, you can check the Map page in order to see if the router has obtained a GPS fix. It is very important to attach the GPS antenna on the router and place it outside (not inside of a building). The router will not be likely to obtain a GPS fix otherwise.

The figure below is an example of the General page and the table below provides information on the fields contained in that page:

Field	Value	Description
Enabled	yes | no; default: no	Turns the GPS service on or off.
Galileo NMEA support*	yes | no; default: no	Turns support for Galileo satellites on or off.
Glonass NMEA support*	yes | no; default: no	Turns support for Glonass satellites on or off.
BeiDou NMEA support*	yes | no; default: no	Turns support for BeiDou satellites on or off.

*Changing these options requires a modem reboot. Therefore, if you make changes to these options and save them, the router will lose cellular connectivity for about 30 seconds.

NMEA

The NMEA page is used to configure settings related to NMEA sentence collecting and forwarding.

NMEA forwarding

Field	Value	Description
Enable	yes | no; default: yes	Turns the main rule on or off.
Rule priority	Low priority level | High priority level | Panic priority level | Security priority level; default: Low priority level	The rule's priority.

Send period	integer [0..999999]; default: 20	How often (in seconds) gathered data is sent.

Secondary Rules

---

The Secondary rules section provides you with the possibility to create additional data sending rules. The difference from the main rule is that the secondary rules only send data when the router uses a specified type of WAN and when the digital isolated output is in the specified state.

Refer to the figure and table below for information on the configuration fields of the Secondary rules section.

Field	Value	Description
Enable	yes | no; default: yes	Turns the rule on or off.

Rule priority	Low priority level | High priority level | Panic priority level | Security priority level; default: Low priority level	The rule's priority. Different priority settings add different flags to event packets, so they can be displayed differently in the receiving system. The router sends data of higher priority first. Priority levels from highest to lowest are as follows: Security Panic High Low

---

The Check Analog section is used to set how often the router checks the value of the analog input. This is relevant to input rules related to the analog input.

Input Rules

---

The Input Rules section displays existing input rules. To create a new input rule look to the section below (AVL Input Configuration), select input type, trigger and click the 'Add' button.

To configure an input rule click the 'Edit' button located next to it. The figure below represents a newly added rule with default settings. Refer to the table below for information on the fields contained in the input rule configuration section.

The router sends data of higher priority first. Priority levels from highest to lowest are as follows: Panic High Low

GPS Geofencing

A geofence is a virtually defined boundary for a real-world geographic area. The GPS Geofencing page provides you with the possibility to set this custom area and apply rules that will inform you when the device leaves or enters the geofence.

The figure below is an example of GPS Geofencing configuration and the table below provides information related to that configuration:

Field	Value	Description
Enable	yes | no; default: no	Turns the Geofence rule on or off
Longitude (X)	degrees [-180.000000..180.000000]; default: 0.000000	East-west position of a point on the Earth's surface. Combining this and the Latitude information will produce a point on the world map that will serve as the center of the geofence area.
Latitude (Y)	degrees [-90.000000..90.000000]; default: 0.000000	North-south position of a point on the Earth's surface. Combining this and the Longitude information will produce a point on the world map that will serve as the center of the geofence area.
Radius	integer [1..999999]; default: 200	Radius (in meters) of the geofence area.
Generate event on	Exit | Enter | Enter/exit; default: Exit	Specifies whether the rule should be triggered when the device enters the geofence area, leaves it or on both events.
