Latest modifications include the replacement of the outdated RS232/TTL serial interface converter to a USB/TTL converter. Also visible on the left is the Lantronix XPort. Schematic AIS decoder schematic PCB PCB with audio connector expecting audio from the scanner’s discriminator. RadioMetrix or similar receiver tuned to AIS, or 3.5mm connector for scanner input.Images of the resulting hardware with the PCB inside an aluminium container, with a laser cut plexiglass front panel, with holes for the LEDs and USB type-B connector. The moment the decoder is connected to the PC a new “virtual” serial port will appear under the Windows “Device Manager”. The information is sent as “AIVDM” strings at a speed of 38400 baud. The decoder sends NMEA “sentences” to the PC through the serial/USB interface. The only difficulty was trying to “squeeze” the 4k RAM required by the original program into the 1k of RAM available on my chip. The C code was then ported by me to the ATMEL family to support an ATMEGA-8 running at 8 MHz. The source code was originally developed for a Stellaris Microcontroller LM38S11 by Peter Baston. This receiver is capable of receiving and processing only ONE of these. AIS is broadcast by vessels interchangibly on two frequencies. It assumes you already have a VHF receiver / scanner that covers the marine band AND that you have access to its discriminator output. Alternatively you may use a radio module from RadioMetrix which is a pretuned single frequency receiver.
