RAY 240 Processor and Interconnect PCBs Circuit Description Introduction The processor board is the central control unit of the Ray240 VHF system. It controls the system in response to commands received from the handsets and, conversely, reports the system status to the handsets for display. - Page 7 FSK signal is determined by very accurately controlling the rate at which the digital inputs to the FSK modulator are switched.

- Page 8 The second of the microcontroller’s UARTs is used for serial communications with external systems, such as GPS. The UART can be connected either to a Seatalk interface (Raymarine’s proprietary single wire half-duplex communications interface) or to an NMEA0183 transmitter and receiver.

12.5 kHz steps. When the radio is transmitting, the VCO operates between 155.000 MHz and 165.000 MHz, and when the radio is in receive mode, operates between 133.600 MHz and 141.875 Page 11 Raymarine Limited. Registered in England. Company no. 1177969 Registered Office: Anchorage Park, Portsmouth P03 5TD... - Page 12 The filters for the CH70 receiver are tuned using the method mentioned above, however these voltages remain at a fixed level. The processor PCB also generates these voltages. Page 12 Raymarine Limited. Registered in England. Company no. 1177969 Registered Office: Anchorage Park, Portsmouth P03 5TD...
- Page 13 This device has an output pin whose voltage is relative to how noise the received signal is. This voltage is used by the processor PCB to determine whether the squelch should be opened or closed. Page 13 Raymarine Limited. Registered in England.

The key matrix can thus be driven to allow only one key to be active at any time and will not ‘lockout’ the distress key or PTT key if any other key on the keypad is pressed. Page 15 Raymarine Limited. Registered in England. Company no. 1177969 Registered Office: Anchorage Park, Portsmouth P03 5TD... - Page 16 The interface that the system uses to communicate to the main processor is based on the Seatalk interface that is widely used in Raymarine equipment. The hardware configuration has been based very closely on that used on many other Raymarine equipment, with some slight resistor changes to ensure correct operability with a 3.3V processor supply.
- Page 17 The PTT switch is monitored by the processor and is therefore ignored if pressed whilst initial setup is undergone. After initialization has completed, the PTT switch position is echoed onto the PTT line by TR10, operated by the micro-controller. Page 17 Raymarine Limited. Registered in England.
