Reply to "Serial Data over copper pairs"

The Telebyte 245 device is similar, but additionally, it is optically isolated.

To those of us who have seen timing laptops burst into flames due to ground drain off hill pairs, and have seen 100 false impulses fire off in 5 seconds due to static discharge off hill pairs in 18% humidity, opto-isolation is priority one. Ideally, there should be no physical connection between the timing bldg and the hill pairs, only optical ones.

Bear Creek is a very short race hill in a place that rarely gets bitterly cold, so you may get away with not being opto-isolated, but I wouldn't recommend it. Consider a Blinky Box (Link to Blinky Box Manufacturer and opto-isolated line drivers.
