This project is for a business with a bunch of locations. Looks like I could need a couple dozen displays so thats around a hundred large digits.
I am not sure on the distance needed. could be 50 to 100 ft. I was going to try it with the included receiver in the kit I mention in my first post. Maybe try some RS485 chips I have. Given the info I could always slow down the data rate. From the time the info is known and typed in to the time it is displayed can be a couple seconds.
