This provides the higher protocol layers to implement a complete Class B AIS transponder when used in the hardware architecture provided by the DE70322TC demonstration / evaluation kit (which includes the CMX7032 AIS Baseband Processor and CMX902 RF PA device) coupled with customer-specific power supplies and interface conditioning. The SCT7033 is provided in a LQFP100 14 x 14 mm package. The SCT7033 provides: C-BUS interface and controller for the CMX7032 AIS Baseband Processor SPI interface and controller for dual LMX2571 frequency synthesisers and VCOs. UART interface and controller to uBlox M8M GNSS module USB and UART interfaces and drivers for the Presentation Interface Additional UART for dedicated GNSS interface LED indicator drivers for channel and operational status Optional GPIO for future customisation GNSS aligned Slot Clock output for synchronising CMX7032 2019 Sicomm Technologies Ltd AIS Class B Protocol Stack Processor - CSTDMA SCT7033 The SCT7033 is available with GUI software to allow: Factory set-up and adjustment of DE70322TC parameters User-specific programming (MMSI and other vessel-specific parameters) Support for exactTrax operation The SCT7033 is delivered with the MMSI set to zero and so will not be able to transmit until programmed with a valid and 1 appropriate MMSI, which must be obtained from the local regulatory body . The GUI is provided in two modes, one for manufacturer / factory only and the second for dealer use, it should not be made available to the end user / mariner. In particular, re-programming the MMSI is not possible without first executing a manufacturer-only sequence. The DE70322TC provides the serial interfaces as CMOS-digital compatible UARTs, the customer must provide suitable interface driver/protection to implement either RS232 or NMEA-0183 compatible interfaces. Other interface options can be implemented at the customers discretion WiFi, Bluetooth etc. but are outside the scope of this document. 1 In the UK this is OFCOM.
