There is going to be a rowing race at the end of this month. The race administrator needs three referees to go to three different locations for watching the race. So he wants to look for remote control system for a starting light system for rowing races, he would like to use your one 8 channel remote and 3 CB-8 transmitters for getting timing splits from 3 different locations on a race course, the distances from the receiver and the transmitter is 1500 meters, 1000 meters and 500 meters. He wants to know it is possible to do?
Maybe he needs a 8 channel long-range RF remote. With 8 working modes, this kind of RF remote can be set different working mode as long as he like. The maximum working current of each relay is 5 amp. The working distance is up to 2000m (6000 FT) in open air with external mount antenna. The most important point is that one receiver can pair with three transmitters when they are used together.
As seen in the picture, each light is connected to normally open terminal of each relay individually.
So as the administrator said, this remote control is for starting light system to get timing splits from 3 different locations. Then, the first referee goes to 1500 meters from the receiver with the first transmitter. The second referee goes to 1000 meters from the receiver with the second transmitter and the third referee goes to 500 meters from the receiver with the third transmitter.
Each person in different location can remote control the same receiver.
