RUT850 GPS

The information in this page is updated in accordance with the RUT850_R_00.01.04 firmware version.

Summary

The Global Positioning System (GPS) is a space-based radionavigation system. This page is an overview of the GPS service in RUT850 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:

File:Networking device manual gps map v2.png

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.

NMEA

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

NMEA forwarding

---

The NMEA forwarding section is used to configure and enable NMEA forwarding. The figure below is an example of the NMEA forwarding section and the table below provides information on the fields contained in that section:

Port	integer [0..65535]; default: 8500	Port number off the server to which NMEA data will be forwarded.
Protocol	TCP | UDP; default: TCP	Protocol that will be used to send NMEA data.

NMEA forwarding cache

---

The router caches NMEA forwarding information if NMEA forwarding is enabled. This section is used to select the memory type where the cache will be stored and the maximum amount of data that will be saved:

Send digital input (2)	yes | no; default: no	Includes digital input #2 state in GPS data package to be sent to server.

AVL

The AVL page is used to set up GPS data sending to an AVL server.

AVL Server Settings

---

The AVL Server Settings section is used to configure the main parameters of data sending to an AVL server. The figure below is an example of the AVL Server Settings section and the table below provides information on the fields contained in that section:

Field	Value	Description
Enabled	yes | no; default: no	Turns data sending to AVL server on or off.
Hostname	ip | host; default: 192.168.1.5	IP address or hostname of an AVL server.

Main rule

---

The Main rule section defines how and when GPS data will be collected and sent to a specified AVL server. Refer to the figure and table below for information on the configuration fields of Main Rule.

File:Networking device manual gps avl main rule v3.png

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. 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

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.

File:Networking device manual gps avl secondary rules v3.png
