N2K Compatible Transducer Change Over Switch

N2K Compatible Transducer Change Over Switch | A+T Instruments

Part number: ATCOSN1
Price: GBP 675 ex VAT and shipping

Product Sheet

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

N2K Compatible Transducer Change Over Switch | A+T Instruments

Part number: ATCOSG1
Price: GBP 675 ex VAT and shipping

Product Sheet

A simple gravity switch that selects the sensor and passes it through the direct signals to the instrument system. 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, it prevents the unwanted switching between transducers whilst sailing in light breeze, downwind, motoring or stationary. The standard version works on gravity alone to calculate which transducer to use. Can also be supplied with a manual selection switch and NMEA0183 input allowing for selection on apparent wind angle (often used on multihulls).

Loadcell Amplifier, serial & 0-5v output

Loadcell Amplifier, serial & 0-5v output | A+T Instruments Accessories

Part number: ATDLA01
Price: GBP 935 ex VAT and shipping

Product Sheet

Converts standard load cells or load pins into RS232, NMEA 0183, CANbus (NMEA 2000 ready), Bluetooth option or 0-5V analogue data. It also has a trip relay for use as an alarm output or limit switch. This unit can be connected directly to our Stowe Dataline GX display and Loadpin to work as a standalone system, with user friendly calibration and alarm settings carried out entirely from the display buttons. Alternatively it can also be calibrated from a PC connected via RS232 or via a push button and adjustment inside the top cover. The unit 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 unit can be logged using a PC running Expedition software. In general it offers fantastic accuracy, stability and noise immunity.
