Data

The data page is used to configure outgoing and incoming data. Using this page it is possible to configure a data stream going to an external logging device. Data can be send over ethernet (UDP), or by using the RS232 protocol.

Sensor specification

If an RS-232 port is not present in the housing of the system, the data lines are embedded in the Lemo-connector and a specific cable/box may be necessary to access the RS-232 port.

Data over ethernet

	Entry	Description
	Stream data over UPD	Enable/disable the datastream
	Ip address	The address where to send the data
	Port	The address where top send the data
	Data included in the stream	Configure which messages are included in the data stream (see JSON sensor documentation for a descript of the data)

RS232 port

Entry

Description

Mode

Output: Stream data: Send the sensor data in the JSON format over RS-232
This setting will add the configuration of the included messages in the data stream (see JSON sensor documentation for a descript of the data)

Output: Medusa NMEA strings: Send the sensor data in the Medusa NMEA protocol over RS-232
This setting will add the configuration of the included sensors in the data stream, and the channels to sum option (see Medusa NMEA protocol documentation for the description of the data).

Output: GPS and total counts strings: Send the GPS and total counts data in a single line over RS-232
Format: #Sensordata, Unix-Timestamp, Lat, Lon, Total-Counts\n
Example: #Sensordata,1596015020973,53.2110364,6.612181,375

Input: RTCM GPS corrections: These corrections will be passed to the GPS and enable RTK precision
Input: NMEA strings: This option will listen for GGA NMEA messages and will parse these for latitude and longitude. Other messages than the GGA string will be ignored.
Input: CSV formatted data: a CSV array streamed to the RS-232 port will be stored in a CSV_external JSON data entry in the project.
Input: JSON formatted data: a JSON formatted string streamed to the RS-232 port will be stored in a JSON_external JSON data entry in the project.
Input: text data: Text streamed to the RS-232 port will be stored in a TXT_external JSON data entry in the project.

Baud rate

The baud rate of the RS-232 connection

Show incoming data

Open a pop-up where the incoming data can be inspected. Note that this is the JSON string generated by the mDOS system. If the syntax of the incoming data is not correct, e.g. not a correct JSON in the case of Input: JSON formatted data, no data is shown.

NTRIP

NTRIP messages are correction applied to the GPS data and enable RTK precision (centimetre) of the GPS. For this, an external source of corrections is needed and these are passed through an NTRIP service.

	Entry	Description
	Enable	Enable/disable NTRIP messages
	Host	The IP address or website of the host
	Username	The username for the NTRIP service
	Password	The username for the NTRIP service
	Select mountpoint	The mountpoint used for the RTK corrections. A list can be retrieved by selecting a correct host and port and then using the request mountpoints button.
	RTCM indicator	An indicator showing RTCM messages are coming in.
