During the summer months we race modified riding lawn mowers on a 200ft drag strip that is set up on a city street. We have the timers, light traps, Christmas tree etc to make our events look like a real NHRA event. Our problem is that everything at the finish line is connected with cables that run 200+ feet down the middle of the track. They take a long time to run and are susceptible to damage if a mower crosses the middle of the track. The fastest mower running last year went 200 ft in 3.9 sec @ 71.5 mph, lots of fun until you fall off.
I need to run the finish line timing light, speed timing light, win light low voltage relay signal analog signals into a RBP and wirelessly transmit 200 feet to another RBP to convert back to analog. Tha manufacturer of the timing system will not help us, I've had to scope all the signals to determine what is going on.
Is this possible, if so can somebody point me the right direction? Power for the RBP will be provided by a car battery supplying an inverter, we have plenty of AC and old PC power supplies for DC.
Thank you in advance for your help
