B953 Class B AIS Transceiver - 5W SOTDMA with VHF Antenna Splitter**As the FCC requires all units sold in the US to be programmed by a qualified technician. Please submit the form below for programming at the time of purchase. A copy of the MMSI registration or FCC Ship Station License is required along with the vessel master or owners signature on the completed programming form.**Click here to download form.The B953 is a high transmit power (5W SOTDMA) AIS Class B transceiver that is small, and lightweight, yet delivers the very best AIS receive and transmit performance so you see more AIS information and targets at maximum range – all achieved with the least power consumption.The B953 has an integrated VHF antenna splitter which enables the transceiver to share your existing VHF antenna without any loss of performance. With built-in intelligent connectivity, integrated next-generation GPS receiver & antenna, and a unique FLEXI-FIT bracket system, safe and secure installation is simple.Features:Certified AIS Class B – 5W SOTDMAIntegrated VHF antenna splitterGlobal certification - USCG / FCC / Canada / EuropeSRT-AIS™ Transceiver Engine for superlative proven performanceFLEXI-FIT™ bracket system for easy, convenient, and secure installationInternal high-performance GPS receiver and antenna (external antenna optional)Water, pressure spray, and damp proof (IPx6, IPx7 certified)Protected from vibration, shock, and extreme temperaturesSmall and lightweightUltra-low power consumption – best in classGuaranteed connectivity and interoperability with any chart plotter or PCNMEA 0183 & NMEA 2000Automated health and performance monitoringSilent mode (transmit-off) functionEnhanced RF screening to protect against electromagnetic interferenceBuilt-in power surge protectionFail-safe VHF radio operationPhysical & Environmental Specifications:Size (H x W x D): 150 x 115 x 45mmWeight: 415kgOperating temperature: -25°C to +55°CStorage temperature: -25°C to +70°CIngress protection: IPx6 and IPx7Electrical Specifications:Supply voltage: 12V or 24V DCSupply voltage range: 9.6V - 31.2V DCAverage current (at 12V): 245mAPeak current: 2.5AAverage power consumption (at 12V): 2.9WGalvanic isolation: NMEA 0183 inputs only, NMEA 2000, VHF antenna portConnectors:VHF antenna: SO-239GNSS: TNCPower: 12-way circular multipoleNMEA 2000: 5-way Micro-C connectorUSB: USB Micro-BData Interfaces:NMEA 0183: 2 x bi-directional portsNMEA 2000: NMEA 2000 Ed 3.101, LEN=1USB: PC virtual com port for NMEA 0183 dataStandards Compliance:AIS standards: IEC 62287-2 Ed. 2, ITU-R M.1371.5Product safety standards: EN60950-1 2006 +A11:2009 +A1:2010 +A12:2011 +A2:2013 EN62311:2008Environmental standards: IEC 60945 Ed. 4Serial data interface standards: IEC 61162-1 Ed 5.0, IEC 61162-2 Ed 1.0NMEA 2000: NMEA 2000 Ed 3.101GNSS performance standards: IEC 61108-1 Ed 2.0, IEC 61108-02 Ed 1.0GNSS:Systems supported: GPS, GLONASS, BeiDou, Galileo (two of any combination, three including GPS, Galileo)Channels: 72Internal/external antenna: Internal or optional external antennaTime to first fix from the cold start: 26sVHF Transceiver:VDL access scheme: SOTDMAOperating frequency: 156.025MHz - 162.025MHzChannel bandwidth: 25kHzReceivers/transmitters: 2 x receivers, 1 x transmitterAIS receiver sensitivity (20% PER): -111dBmAIS transmitter power: 5W (+37dBm)User Interface:Indicators: Power, transmit timeout, error, silent modeIn the Box:1 x AIS transceiver1 x Power and data cable (2M)1 x VHF radio accessory cable1 x FLEXI-FIT™ mounting bracketComplete with screws & optional fixing tape
