NMEA-0183 Logger

Preface

The OpenSeaMap data logger is capable of logging data of two NMEA-0183 devices, for example depth-sounder and GPS. For this, there are two input channels. Both inputs will be written with a timestamp for a later chronological sorting. Data about acceleration and displacement will also be logged to determine heeling, heaving and pitching. All data will be written to an SD-card. Data is recorded raw for further processing, no filtering is done.

Features

• Data logger for NMEA-data
• Built-in 6-axis MotionTracking (Gyroscope and Accelerometer)
• Writing data on standard SD-card in NMEA-0183 format
• Simplest handling
• LED for operation, input data, and SD-card access
• 2 NMEA-0183 inputs (4800 Baud)
• 1 Seatalk-1 input alternatively (selectable by internal jumper)
• 12 V supply

Installation

Mounting the logger

Install the logger to a protected location where you have access to the SD card and you can see the LED's.

Mount it as perpendicular as possible to the front panel of the navigation area (outside or inside) or perpendicular to a vertical wall behind. The top edge ideally will be horizontally to the ship's transverse axis. The two arrows on the upper surface indicate the direction in respect to the ship's axis.

Connecting the Cable

The logger will turn on automatically with the operating voltage. After switching on it takes about 30 seconds the logger starts to write data. If the green power indicator LED is lighting, the logger is active and ready to receive. The connection is made via the RJ45 jack. This is where all signals and the supply are connected.

A suitable cable comes with the logger. In case that you need to buy a longer one, please use a simple normal patch cable (network cable) as it is available at any electronics store. Make sure that this is not a "crossover" cable or "cross cable" for directly connecting two computers. Cutting the patch cable in half, you need only one side (connector and open end). The colors show you if that cable is European or American. Are the cables in the crystal plugs on one side green, you've got a cable according to the European standard (568A), these are orange it is a American standard (568B).

There are the following connections:

Pin	-568A pairno.	-568B pairno.	-568A color	-568B (AT&T 258A) color	Logger meaning
1	3	2	white/green line	white/oranger line	Seatalk -
2	3	2	green/white or green	orange/white line or orange	Seatalk +
3	2	3	white/orange line	white/green line	NMEA A -
4	1	1	blue/white line or blue	blue/white line or blue	NMEA B +
5	1	1	white/blue line	white/blue line	NMEA B -
6	2	3	orange/white line or orange	green/white line or green	NMEA A +
7	4	4	white/brown line	white/brown line	GND
8	4	4	brown/white line or brown	brown/white line or brown	+12V

Connecting the Sounder

Connect the NMEA output of the sounder/sonar to the NMEA input of the logger.
Use the NMEA-A for the sounder/sonar if possible.

Signal Sonar	NMEA-A
-	Pin 5
+	Pin 4

If the Sounder works with Satalk-1, you can switch port A from NMEA-0183 to Seatalk-1.

Connecting GPS

Connect the NMEA output of the GPS device to the NMEA input of the logger.
Use the NMEA B for the GPS if possible.

Signal GPS	NMEA-B
-	Pin 3
+	Pin 6

Connecting Seatalk

The channel A of the logger can be switched to the Seatalk-1 protocol.
These two steps are necessary:

1. Please open the logger. There is a red jumper in the middle of the board. On the board you will find the words Seatalk / NMEA. For NMEA protocol, the bridge put on the right and the middle pin, which are on the NMEA site. For Seatalk on the left and the middle pin.
2. Start the configuration program and create a configuration file with the appropriate entries. Put this configuration file on an SD card and start the logger with this card.

Connecting supply (12V)

The logger is operating with 12V voltage (9V ..15V). To start the data recording automatically when the navigation devices are turned on, the logger must be connected to the same circuit as the navigation instruments.

Supply	Cable	Color
GND	Pin 7	white/brown line
+12 V	Pin 8	brown/white line or brown

Connecting Cable

Ideal are terminal strips. If you connect the cable to a terminal block, you can bend the stripped end, it keeps better in the terminal block.

Strain relief

The loose end of the cable must be secured with a strain relief when connected to the onboard electronics (the wires are very thin).

Functions

After applying the operating voltage and a short initialization time (30 seconds), the data is written automatically to the SD card.

Control panel

The control panel is self-explaining:

SD card	Insert SD card	We recommend a 4GB SD card. It can record up to 40 days. The SD card must be formatted FAT-32.
Active/write	Green       Red flashing	the logger is active and ready to receive the logger writes to the SD card
RJ45 Connector	Connect power supply connect sonar connect GPS           Gelb/Green flashing	on the NMEA channel a valid signal is received

Insert the SD card before turning on.
Remove the SD card from the logger only when the unit is turned off.

On every start and every hour a new file on the card will be created automatically.

Errors

When an error occurs while writing the data, e. g. during start or operation of the logger, the red LED flash regularly every second:

Where	What	Meaning	Action
LED next to plug	Red flashing	SD-card is full	Change SD-card with an empty one

Other possible causes:

• SD card has an unsupported file format (for data cards there is only FAT16 and FAT32 supported)
• SD card is not writable or is not recognized. Please test the card on your PC.

Operating LEDs

Where	What	Meaning
LED next to plug LED 1 in plug LED 2 in plug	Green off   off	The logger is active and reciving
LED next to plug LED 1 in plug LED 2 in plug	Green flashing	Initialization of the logger (about 30 sec)
LED next to plug LED 1 in plug LED 2 in plug	Red	The logger is currently turning off.

LED next to plug LED 1 in plug LED 2 in plug	Yellow flashing       Green flashing	in this NMEA channel is a valid signal is received in this NMEA channel is a valid signal is received

Preparing the SD card

We recommend a 4GB SD card. It can record up to 40 days. (about 4MB per hour, 100MB per day). The SD card must be formatted FAT-32.

Firmwareupdate with SD card

A SD card with FAT 16 file system must be used for the firmware update. The easiest way is to use a SD card with 2 GB or smaller. This can be simply formatted with FAT 16 (on some operation systems are also just plain FAT) or creating a small partition. The latest firmware file can be downloaded, and put on the root of the SD card.

A software tool that simplifies the update process is in progress.

Programm "OpenSeaMap-Logger"

Mit dem Programm [http:// "OpenSeaMap-Logger"] kann man Tiefen-Daten hochladen und den Logger konfigurieren:

1. Daten hochladen
2. Logger konfigurieren:
   1. Kanal A: Baud-Rate umstellen
   2. Kanal A: umschalten Seatalk/NMEA
   3. Kanal B: Baud-Rate umstellen
   4. Aufzeichnung der Gyrodaten abschalten
   5. Write board supply (?)
   6. Vessel_ID (? Macht vermutlich nur Sinn, wenn immer die selbe SD-Karte für immer das gleiche Schiff und gleichen Logger verwendet wird? Also nur für Eigner-Schiffe.
3. Firmware aktualisieren (Hier muss man unbedingt /vorher/ die Daten hochladen!)
4. Prog Settings (noch in Arbeit)
5. Restore SD-card (Was geschieht da?)

Operation

For the skipper

Start

If the logger is connected to the power supply of Navigation Devices,
it starts automatically when the navigation devices are turned on.

If the navigation devices be turned off (or if a power interruption),
the log file is automatically closed.

Once the power supply is switched on again, a new file is created automatically.

The logger has an built-in power-backup-circuit
ensuring there is no data write fault during interruption of the supply voltage.

SD card

On an SD card with 2 GB can be recorded for about 18 days.
Approximately 100MB of data recorded per day.
(This can of course vary according to the GPS and sonar used.)

Thus, the SD card needs to be replaced in time.

For charter organisations

For simple handling, use 2 SD card to each device.

After each charter trip the SD card needs to be replaced.

To do this, labeled for each vessel 2 SD cards with the ship's name.
A card is plugged into the logger, the other comes into the office to vessel/charter-documents.

The logger automatically starts with the navigation device.
The charter customers need to worry about anything.

Die folgenden Checklisten können für die eigene Basis angepasst werden:

When crew changes

1. remove the written card
2. insert new empty card (from the vessel documents)
3. bring removed card with the ship's documentation to the office

During crew briefing

It would be nice if the charterers employee in charge briefly tells that the charter company participates in the project "Detection of shallow water depths". And that the skipper can support the project particularly well by selectively moves a bit in bays and harbor entrances back and forth to capture the depth of the key points well.

This could also be advertised on your website.

In the office

1. put removed card into a PC and upload data to the server.
2. assign the uploaded data to the correct ship (choose from the list of vessels)
3. Erase data on the described card,
   put empty card to the shipping documents.
4. Note in the ship's documentation:
   Data uploaded <trip/customer> <date>
   Data deleted <trip/customer> <date>

Meta data

For a reliable evaluation, we need accurate information about the ship and the measuring device used.

These data need be entered only once per vessel and are then valid for all log files for this ship. Changes to marine electronics, the original data can be easily changed or expanded.

Uploading data

1. You need a computer with Internet connection and SD card reader
2. Put the SD card into the SD card slot
3. Please log in using your username: http://depth.openseamap.org
4. Enter the metadata of your ship and to the measuring device.
   If you use the same ship as the last time, and if nothing was changed in the measuring device, you can simply select your ship from the list of your ships.
5. Upload the data to the server
