Warranty and Technical Support The Device warranty is valid for two years from the date of purchase. If a Device was purchased in a retail store, the sale receipt may be requested when applying for a warranty claim. The Device warranty is terminated in case of violation of the instructions in this Manual, case integrity breach, or repair or modification of the Device without the manufacturer’s written permission.

Operating temperature range -20..55 °С Yacht Devices Ltd declares that this product is compliant with the essential requirements of EMC directive 2004/108/EC. Dispose of this product in accordance with the WEEE Directive. Do not dispose of electronic refuse with domestic or industrial waste.
II. Installation and Connection of Device All connections should be made when the power is cut off at the circuit breaker. This will protect against accidental short circuits during installation. Connect the Device to the tank level sensor before making the connection to the NMEA 2000 network.

1.1 Standalone sensor connection If you do not have a gauge connected to your tank level sensor (e. g. you have installed the sensor yourself), you should connect only two wires to the Adapter: from SENS to the sensor «Signal» or «+» output and from GND to sensor «Ground»...

Figure 1. Standalone sensor connection (left) and connection in parallel with Volvo MDI unit (right) 1.3 Connection in parallel with an existing analog gauge An analog gauge connected to your tank level sensor can be of two types: with one measuring coil (the gauge has only two terminals) or with two measuring coils (the gauge has three terminals).
Page 11
1.3.1 Connection to a 1-coil gauge If the gauge has one coil, the VREF input should be connected to the gauge’s power terminal (up to 16 Volts), the SENS terminal to the gauge «Signal» input, and the GND terminal to the fuel sensor’s ground terminal.
Page 12
1.3.2 Connection to a 2-coil gauge If the gauge has two coils, the VREF terminal should be connected to the gauge’s power terminal (up to 16 Volts), the SENS terminal to the gauge’s «Signal» input (or to the fluid level sensor’s «Signal» wire after the measurement activation button, see Figure 3), and the GND terminal to the gauge’s «Ground»...

1.3.3 Neutralize gauge effects When using an Adapter with an existing gauge, you will need to measure its coil resistance values with an ohmmeter or multimeter and set the measured values to the configuration with the command YD:OHMS_ GAUGE (refer to Sections VI.3.3). To make an accurate measurement, you will need to warm up your gauge: turn it on and let it operate for approx.

2. Connection to NMEA 2000 The Device should be connected to the NMEA 2000 network backbone with a NMEA 2000 drop cable (not supplied with the Device). The Device is equipped with a DeviceNet Micro Male connector. For NMEA 2000 networks with other connector types, you will need an appropriate adapter cable. Before connecting the Device, turn off the bus power supply.
III. LED Signals The Devices incorporates a bi-color Device status LED (labeled “N2K”) and four channel status LEDs. Their locations are pictured in Section I on Figure 1. 1. Powering on One 1-second long GREEN flash of the status LED after powering on the Tank Adapter confirms successful initialization.
IV. Device Configuration and Settings Configuration of the Device should not be performed at sea. The Device can be configured by two different methods: 1. By selecting one of predefined configuration presets using the hidden button. This method is limited by standard resistive sensors and connection with Volvo Penta MDI units, and does not allow configuration of the calibration curves, digital switching functions, setup of the connection in parallel with analog gauges, or use of the voltage sensors.
Page 17
C. Connection type. The Adapter support multiple sensor’s types (resistive, voltage, Volvo Penta MDI) and different connection schemes (standalone, in parallel with 1-coil or 2-coil gauges). In case of a parallel connection, you should measure the resistance of a gauge’s coils and specify it in the Device’s settings;...
V. Configuration with Presets (Button) Press the hidden button (see Figure 1 in Section I) with the paper clip supplied with the Device. The status LED of the Device will constantly shine RED and channel LEDs will display the preset number in binary (A is the lowest bit, D is highest, see the Table 1 below) when the hidden button is pressed.

Table 1 continued 4 (0100) Channels AB are connected to fuel tanks (0 and 1), and CD to water tanks (0 and 1). Sensors are of resistive type (USA, 240..33 Ohm). 5 (0101) Channels AB are connected to fuel tanks (0 and 1), and CD to water tanks (0 and 1). Sensors are of resistive type (EUR, 10..180 Ohm).
VI. Configuration with Installation Description Strings Installation description strings are stored in the Device’s memory and are usually written by installers to specify the device location or to leave notes or contact information. They can be set with a PC software and a hardware gateway to the NMEA 2000 network.

Yacht Devices NMEA 2000 Wi-Fi Gateway, Yacht Devices NMEA 2000 Ethernet Gateway, Yacht Devices NMEA 2000 USB Gateway or Yacht Devices NMEA 2000 Wi-Fi Router is required to connect the PC to the NMEA 2000 network. The CAN Log Viewer also allows you to modify the NMEA 2000 device instance by entering a value in the dedicated field (see «Address Claim»...

1.3 YD:DEV [0..255] Switches NMEA 2000 devices instance to specified value. This setting is used in large NMEA 2000 networks and does not effect the Device’s behavior. 1.4 YD:SYS [0..15] Switches the NMEA 2000 system instance of the Device to the specified value. This setting is used in large NMEA 2000 networks and does not effect on Device’s behavior.

Example 1. Get the tank number of the channel A: YD:TANK A Example 2. Set the tank number of the channel B to 5: YD:TANK B 5 2.2 YD:FLUID <A..D> [type] Where: [type] can be a number 0..15 or one of NMEA 2000 predefined types, they have numbers 0..6 correspondingly (DIESEL, WATER, WASTE, LIVEWELL, OIL, SEWAGE, GASOLINE) Sets the fluid type for the specified channel or returns the type if the second parameter is omitted.

3. Sensor configuration 3.1 YD:CONNECTION <A..D> [NC | RESISTIVE | 1COIL | 2COIL | VOLTAGE | 2COIL_VCC | MDI] Sets the sensor type and connection type for specified channel (see Section II). With factory settings, all channels are configured for RESISTIVE type (standalone connection to resistive sensor). The NC type means “not connected”...

Sets the resistance of analog gauge coils (in Ohms) for parallel connections (1COIL, 2COIL, 2COIL_VCC). For 1-coil gauges, the third parameter should be omitted. For 2-coil gauges, first number is the resistance of Coil 1 and the second is the resistance of Coil 2 (see Figure 3 in Section II). This setting neutralizes the effects of the gauge caused by its own resistance.

4. Advanced configuration commands 4.1 YD:CALIBRATION <A..D> [p4,p8,...,p95|OFF] Where: p4,p8,…,p95 — 12 calibration points (decimal values, 0..100) Resistive fuel level sensors do not take the shape of the fuel tank into account; therefore, the readings usually have substantial error. The same issue is applicable to the voltage-output sensors which do not have an internal calibration mechanism, neither do they have a non-linear output.
NMEA 2000 two-state devices (e. g. relay banks). The Tank Adapter is compatible (not only) with: * Yacht Devices NMEA 2000 Circuit Control YDCC-04. Circuit Control has one bank of four latching (bi-stable) relays capable of switching direct current (DC) and alternating current (AC) loads.

The Device allows setting up to 8 rules for each measurement channel (A..D), four to switch the digital switching channel ON, and four to switch OFF. The condition can be programmed by tank level (more or less than specified value) or by sensor state (are readings available or sensor is failed). The common command’s syntax is shown above.
Page 30
Example 3. Turn off the ON rule with number 1 at channel A (defined at Example 2): YD:SWA1 ON NEVER The command without parameters or with the rule type only, returns the current settings. Example 4. Get the settings of the ON rule with number 1 at channel D (defined at Example 1): YD:SWD1 ON Example 5.

Microsoft Windows, Mac OS X and Linux: http://www.yachtd.com/products/can_view.html The program must be connected to an NMEA 2000 network with a Yacht Devices USB Gateway YDNU-02, or a Wi-Fi Gateway YDWG-02, or an Ethernet Gateway YDEN-02, or a Wi-Fi Router YDNR-02.
