Current Options (WIP)

Single Pair Ethernet

Requires isolation transformer but potential viable method with right transceivers and receivers

Single Pair Ethernet Brief

Wireless

Not the best option as it isn’t very secure (can be hacked into unless we want to put effort into protection methods)

Digital Isolators
