The AIS Class B receiver and transmitter unit is the culmination of six years AIS development, and the application of some of the most advanced wireless digital development skills and techniques. The result is a small, low cost, reliable, robust and high performance product suitable for a variety of applications within the AIS environment.
Features
Simple Design Concept
TCB's AIS Class B is an elegant single PCB solution optimising the combined application of hardware and software
Standard NMEA interface
As standard the TCB Class B can be connected to any NMEA compatible GPS plotter or suitably configured PC or PDA
Anti-Tamper
TCB's Class B is enabled to alert users and/or authorities if the unit has been either removed or tampered with once installed (configurable option additional to the Class B specification
Distress Alert Transmit
Distress alert button enables the user to transmit a distress alert with the GPS position of the vessel (configurableoption additional to the Class B specification)
Water Resistance
Robust, coated aluminium case, to ensure the unit is able to operate in the harshest of environments. IEC60945 - Cat C.
Internal GPS Module
TCB's Class B includes an integral GPS module to facilitate ease of installation and use.
