RUT956 GPS
The information in this page is updated in accordance with firmware version RUT9M_R_00.07.11.1.
Summary
The Global Positioning System (GPS) is a space-based radionavigation system. This page is an overview of the GPS service in RUT956 devices.
General
The General 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 device has obtained a GPS fix. It is very important to attach the GPS antenna on the device and place it outside (not inside of a building). The device 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 | off | on; default: off | Turns the GPS service on or off. |
| Galileo NMEA support* | off | on; default: off | Turns support for Galileo satellites on or off. |
| Glonass NMEA support* | off | on; default: off | Turns support for Glonass satellites on or off. |
| BeiDou NMEA support* | off | on; default: off | 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 device will lose cellular connectivity for about 30 seconds.
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 device and enable GPS in the General page.
The figure below is an example of the Map 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:
| Field | Value | Description |
|---|---|---|
| Enabled | off | on; default: off | Turns NMEA forwarding on or off. |
| Hostname | ip | host; default: none | IP address or hostname of the server to which NMEA data will be forwarded. |
| Protocol | TCP | UDP; default: TCP | Protocol that will be used to send NMEA data. |
| Port | integer [0..65535]; default: 8500 | Port number off the server to which NMEA data will be forwarded. |
| Contain connection | off | on; default: off | Contains active session with the remote server if turned on. |
| Select prefix | Custom | None |Serial | Mac address | IMEI; default: None | Prefix is added to the NMEA sentence before it is transmitted. |
Hosts status
This section displays hosts status information.
NMEA forwarding cache
The device 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:
| Field | Value | Description |
|---|---|---|
| Save cache in | RAM Memory | FLASH Memory; default: RAM Memory | Selects which type of memory will be used for storing NMEA forwarding cache. |
| Maximum sentences | integer; default: 5000 | Maximum amount of NMEA sentences that will be saved in the cache before older entries are deleted and replaced by new ones. |
| File | filepath; default: none | Location of the file where NMEA forwarding cache information will be stored. This field becomes visible only when the selected memory type is "flash". |
NMEA serial forwarding
This section is used to configure NMEA serial forwarding settings:
| Field | Value | Description |
|---|---|---|
| Enabled | off | on; default: off | Turns NMEA serial forwarding on or off. |
| Select prefix | none | Serial | Mac address | IMEI; default: none | Prefix is added to the NMEA sentence before it is transmitted. Example: 0012345567_$GPRMC.... |
NMEA serial ports
This section displays NMEA serial forwarding port instances currently existing on the router. To add a new serial port instance, press 'Add' button:
You will then be taken to the NMEA serial port configuration page:
| Field | Value | Description |
|---|---|---|
| Enable | off | on; default: off | Enable service. |
| Name | string; default: none | Name of serial port. |
| Device | RS232 | RS485 | USB RS232 interface; default: RS232 | Specifies which serial port will be used for serial communication. |
| Baud rate (RS485) | integer [300..230400]; default:9600 | Data rate for serial data transmission (in bits per second (bps)). |
| Baud rate (RS232) | integer [300..115200]; default:9600 | Data rate for serial data transmission (in bits per second (bps)). |
| Baud rate (USB) | integer [300..4000000]; default:9600 | Data rate for serial data transmission (in bits per second (bps)). |
| Data bits | 5 | 6 | 7 | 8; default: 8 | Number of data bits for each character. |
| Stop bits | 1 | 2; default: 1 | Stop bits sent at the end of every character allow the receiving signal hardware to detect the end of a character and to resynchronise with the character stream. Electronic devices usually use one stop bit. Two stop bits are required if slow electromechanical devices are used. |
| Parity | None | Odd | Even | Mark | Space; default: None | In serial transmission, parity is a method of detecting errors. An extra data bit is sent with each data character, arranged so that the number of 1 bits in each character, including the parity bit, is always odd or always even. If a byte is received with the wrong number of 1s, then it must have been corrupted. However, an even number of errors can pass the parity check.
|
| Flow control | None| RTS/CTS | Xon/Xoff; default: None | In many circumstances a transmitter might be able to send data faster than the receiver is able to process it. To cope with this, serial lines often incorporate a "handshaking" method, usually distinguished between hardware and software handshaking.
|
| RS485: Full Duplex | off | on; default: off | Turns Full Duplex mode on or off. This option is available only on the RS485 device. |

| Field | Value | Description |
|---|---|---|
| Enabled | off | on; default: off | Turns NMEA sentence collecting on or off. |
| File | filepath; default: none | Location of the file where NMEA sentences will be stored. This field becomes visible only when NMEA collecting is enabled. |

| Priority | Low | High | Panic | Security; default: Low | The rule's priority. Different priority settings add different flags to event packets, so they can be displayed differently in the receiving system. The device sends data of higher priority first. |
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.
To create a new geofence area, enter a custom name for it and click the 'Add' button. A new geofence area configuration with the given name should appear in the "Geofencing" list. Click the button that looks like a pencil next to it to begin editing.
