The goal of the on board server initialization is to prepare the connections to the network(s) on board, the data sensors and the dual computer.
The server initialization takes places in the config tool, so a display, keyboard and mouse must be connected to the computer. For details about how to access the config tool, see "Accesing the config tool".
When this process is completed, the TelScope software is ready to be started.
The network setup page lists the network interfaces on the computer.
- Type in network details and press "save".
- Repeat for computer B
The computer should usually be assigned a static IP address. The addresses and netmask to be entered here, should have been provided by the IT department of the ship owner.
There are four physical network interfaces. Prior to installation, the IT department should have decided what networks the TelScope computers should connect and how many of the physical interfaces are needed.
In order to complete the initialization of the connection between the dual computers, the IP address of the dual computer on the local must be entered. Please note the distinction between the VPN interface IP address (which was assigned by the shore side servers in the "Shore preparation" step) and the IP of the dual computer on the local network.
To test the connection, use the button to ping the dual computer on the local network. If this doesn't work, something is wrong with either the network setup on one the computers or the configuration of the local network. When IP has been set, test the connection to the dual computer through the VPN tunnel.
Data collection - serial ports
To configure sensor data collection in TelScope a software component called a "data fetcher" must be configured. Data fetchers are specific to type of interface and the format of the data. To collect data over several serial interfaces, a data fetcher must be configured for each interface.
The "Data collection - serial ports" page lists the serial interfaces. Note that if a serial interface named /dev/ttyS0 exists, it should not used. The four physical serial ports are named /dev/ttyUSB[0-3].
- Press "monitor" for the relevant serial port
- Select baud rate.
- Verify that NMEA sentences are received.
- Name the data source. We suggest a short descriptive name consisting of only uppercase letters, numeric characters and underscores. GPS, GPS_1, GPS1, GYRO, GYRO_1, GYRO1 are examples of valid names.
- Press "Save"
IEC 61162-1 / NMEA Sentences in use
TelScope can make use of the following IEC 61162-1 / NMEA sentences:
- Time: GGA, GLL, GNS, GSA, GSV, RMC, VTG, ZDA, GBS, GST
- Position: GGA, GLL, GNS, RMC
- Course over ground (COG): RMC, VTG, OSD
- Speed over ground (SOG): RMC, VTG, OSD
- Speed through water (STW): VBW, VHW, OSD
- Heading (HDG): HDT, THS, VHW, OSD
- Depth (DPT): DBT, DPT
- Wind: MWV
Deploy and status
TelScope is run as a collection of services. The "Deploy and status" page lists the currently running services. The exact set of services will vary depending on the configuration, but the image on the left side is typical for a simple configuration.
- Press "Start TelScope"
Note that the process of applying a new configuration and starting the system takes a few minutes.
