|SPICE circuit design of DC powerline communication circuit
||We want to a SPICE circuit design for simple, low data rate, DC powerline communications;
- 12 to 120 VDC (<5 amps)
- just 2 wires carry both power AND comms
- not twisted pair wires
- 100m cable runs
- low baud rates (9600 would be great!)
- low noise rural environment
- we'll use a protocol like NMEA - that repeats sentences... so lost data/sentences are OK
- happy to re...

||This project is to ultimately create an NMEA interface board that will take signals from a boat Rev Counter, Temperate, Pressure, Fuel level, Leg Position.
Ideally a single product that can be programmed to be configured to take any of the signals. Possible that one product be designed that takes all of them as one.
The first stage of the project is to look at feasibility and material cost...
