NMEA 2000 170kHz (B&G) Depth Sounder Module

NMEA 2000 depth module for use with existing B&G depth sensors providing greater than 100m reliable depth performance on Brookes and Gatehouse H5000 or N2K instument systems. We can also supply new transducers and shut off valve SOV housings.

NMEA 2000 Transducer Change Over Switch

The Tack Change Over Switch allows two NMEA 2000, Simnet, Seatalk NG, or CANbus 'Smart' sensors such as the Airmar DST800 on one instrument system or display. Boat Speed and/or Depth PGN's are automatically routed from either the Port or Starboard transducer or boat speed sensor and output as a single source to the connected instruments. If the apparent wind information is available on the bus then the Tack COS will use this as priority for deciding which tack the vessel is on. If no wind PGN is available then the Tack COS has its own gravity change over switch built in. Installation couldn't be easier. Simply screw to the bulkhead and connect to the bus using the supplied NMEA 2000 connection.

Gravity Transducer Change Over Switch

The standard version Gravity Switch has change over contacts for use with more traditional sensors. However, it is no ordinary gravity change over switch. Running intelligent algorithms, the switch avoids unnecessary switching which causes inaccurate boat speed readings, delayed depth readings and early switch contact failure. With an inbuilt microcontroller, this switch prevents the unwanted switching between transducers whilst sailing in light breeze, downwind, motoring or while the boat is at rest. The standard version works on gravity alone to calculate which transducer to use. There is also an NMEA version that takes NMEA wind angle data to calculate which tack the boat is on, but still using change overcontacts to switch traditional sensors. This version is especially useful in catamarans or other craft with very small heel angle. These Tinley products have been designed to work with almost any manufactures speed or depth instruments.

Digital Loadcell Amplifier

The Digital Loadcell Amplifier converts standard load cells or load pins into RS232, NMEA 0183, CANbus, Garmin GNX mast displays, NMEA 2000, Bluetooth option or 0-5V analogue data. It also has a trip relay for use as an alarm output or limit switch. The DLA1 can be connected directly to our A+T MFD display and Loadpin to work as a standalone system, with user friendly calibration and alarm settings carried out entirely from the display buttons. Alternatively the DLA1 can also be calibrated from a PC connected via RS232 or via a push button and adjustment inside the top cover. The DLA1 has two RS232/NMEA inputs and can be programmed to multiplex these inputs to combine data with the measured load before re-transmitting it via any one of the outputs. The output of the DLA1 can be logged using a PC running Expedition software. The DLA1 offers fantastic accuracy, stability and noise immunity.

NMEA 4-20mA Converter

Further Details

The NMEA 4-20mA converts NMEA 0183 into an isolated 4-20mA current loop. Any NMEA sentence and factor can be catered for and units are pre programmed prior to delivery.

NMEA Old2New V1.5 to V3 Converter

Further Details

The Old2New converts NMEA 0183 V1.5 to NMEA 0183 V3. It can also 'multiplex' 2 NMEA inputs into 1 NMEA output with an additional USB connection for a PC, allowing any navigation software to receive and transmit fully Opto-Isolated NMEA. Additionally, user selectable filters can be set to filter in or out any combination of NMEA sentences independently from either input. Use standalone 2 into 1 NMEA or connect to a PC to automatically provide 2 NMEA into USB and USB back to NMEA. No additional power supply is required when connected to USB. Drivers for Windows Vista, XP, NT, 2000, and 98. Flash upgradeable by end user. Bluetooth option. Custom software service available.

Compatible Replacement B&G Depth Sensor

Fully compatible direct fit replacement sensor for B&G systems including Hydra, Network, Focus, all Hecta versions, Hornet and Hercules Depth sounders. New features include Carbon Fibre body and improvement on signal quality. Various connector options and plastic or bronze compatible versions available. Supplied as shown without retaining ring, so please use original.

Paddlewheel to B&G Underwater Unit Converter

Specifications

Converts new style paddlewheel boat speed sensor signals to old style B&G UWU signals. NMEA output also available as an option, providing a standalone unit with built in calibration and NMEA output to interface to, for instance, a PC or chartplotter.

Analogue input, NMEA 0183, 2 x NMEA 2000 compatible, SimNet, SeaTalk 2, Bluetooth or CANbus bridge

We have hardware ready for programming that can convert any 3 analogue signals into NMEA or CAN BUS. This hardware has two separate CAN buses, so it has also been used as a gateway device to seamlessly 'merge' missing data into existing PGN's. For instance, some engine manufactures such as Yanmar do not include Oil Pressure or Tilt/Trim in the standard PGN, so this device can happily add it so that the receiving instruments believe the information originated from the engine.

NMEA-USB Multiplexer/filter

Further Details

The USB Merge Computer merges and filters 2 NMEA inputs into 1 NMEA output with an additional USB connection for a PC, allowing any navigation software to receive and transmit fully Opto-Isolated NMEA. Additionally, user selectable filters can be set to filter in or out any combination of NMEA sentences independently from either input. Use standalone 2 into 1 NMEA or connect to a PC to automatically provide 2 NMEA into USB and USB back to NMEA. No additional power supply is required when connected to USB. NMEA 0183-HS 38.4 K Baud can be selected on Input 1 and Output whilst still merging standard low speed NMEA through Input 2. This enables the unit to combine ATIS and GPS signals for instance. Drivers for Windows Vista, XP, NT, 2000, and 98. Flash upgradeable by end user. Bluetooth option. Custom software service available.

NMEA Paddlewheel

The NMEA Paddlewheel converts NMEA from either a GPS or electromagnetic log to a paddlewheel output suitable for connecting directly to an instrument system, such as a B&G Hydra/Hercules.

Rudder Angle Indicator with NMEA output

Specifications

This unit can be connected directly to a rudder reference potentiometer, sharing it with an autopilot if necessary, giving a very accurate rudder angle meter with a very fast response! Calibration can now be performed to give absolute position of rudder in degrees or indicate rudder end stops at the meter full scale. Custom scaled meters are also available making this product truly versatile. NMEA output also available.

NMEA to 213 Mast Head Unit converter

Specifications

Converts NMEA into the analogue signals required by a B&G Hydra/H2000/H3000 system.
