Leica 1200 series ASCII - 12

Description

Driver is used to decode the output and control the setup of a Leica 1200 series GPS/GLONASS receiver using NMEA messages and the ASCII version of the "Outside World Interface (OWI)".

The driver decodes the NMEA $--GGA & $--VTG messages to supply Qinsy with a position, course over ground and speed over ground observation.

Driver Information

Database Setup

Position Navigation System

To use this driver create a new system. Choose Position Navigation System and select the Leica 1200 series ASCII driver.

Speed Log System

To use this driver create a new system. Choose Speed Log System and select the Leica 1200 series ASCII.
In order to decode the COG and/or SOG observations use the following slot assignments:

Online

The UI of the driver allows the user to perform the following functions:

1. Setup output messages and their update rate

2. Select the correction source and optionally setup its parameters.

3. Monitor the messages as exchanged by the driver and the receiver.

Important

Each change in the driver settings should be followed by a click on the 'Send' button in order to transmit the updated settings to the receiver.

Output Messages & Update Rate

When this driver is started the UI allows the user to setup the NMEA messages which should outputted by the receiver on the terminal port and on port 2. The output from the terminal port is used decode the position, COG & SOG.
In order to decode the position the user should enable the $--GGA output with the required update rate.

In order to decode the COG and/or SOG the user should enable the $--VTG message with the required update rate.

Correction Source

The driver allows the user to select one of three correction source types. The supported types are UHF Radio, GSM Data and NETPOS based corrections. The switching of configuration is implemented by switching the active configuration set of the receiver and optionally setting some parameters.

UHF Radio Corrections

When the UHF Radio source is selected the user may setup the radio channel. The radio channel represents an offset from a center frequency as used by the integrated radio receiver. Currently it is not possible the set the frequency of the radio directly as this is not supported by the OWI interface.Important: The UHF Radio configuration set in the receiver should be names "UHF RADIO".

GSM Data Corrections

When the GSM Data source is selected the user may setup the telephone number that should be dialed to initiate the connection and the connection status. In case the telephone number is changed the connection status should first be set to disconnect.Important: The GSM Data configuration set in the receiver should be names "GSM DATA".

NETPOS Corrections

When the NETPOS based source is selected the user may select which configuration setup is used by the receiver and its connection status. The possible NETPOS correction sources should be entered in the receiver as configuration sets and their names should be added to the XML file 'DrvQpsTerminatedUI.xml'.

A default version of this file can be found in <Qinsy install folder>\Drivers\Settings. In order to have the driver use the user defined names, the default file 'DrvQpsTerminatedUI.xml' should be copied from the Qinsy Installation folder to <public documents>\QPS\Qinsy\Drivers\Settings (<commondocuments> is normally C:\Users\Public\Documents) and that copy should be modified to the users liking. The file in <public documents> will take precedence over the file in the Qinsy install folder.

Availability of Qinsy sub folder in public documents

If the sub folder of the <public douments> folder does not yet exist on your system, you may manually create it. Another option is to go online once with a setup with this driver, the directory will then automatically be created.

The  '<Name>' tag of each station should match those of the corresponding receiver configuration set. The other tags are currently not used and are reserved for future expansion.Important: The length of the content of the <name> tag should not exceed 17 characters as this the maximum supported by the receiver.

Monitor OWI messages

The list control at the bottom of the UI allows the user to monitor the message exchange between the driver and the receiver. The messages prefixed by '=>' are sent to the receiver and the messages prefixed by '<=' are received from the receiver.

Drivers IO Notes

The following command line options may be added to the line for this driver in the 'Drivers.io' file.
