The ProPAC-3 adheres to standard EIA RS-485 hardware specifications. The RS-485 specification provides
for a minimum of 32 driver/receiver pairs to be connected on a communication network with a maximum
length of 4,000 feet. The cable of choice for RS-485 applications is shielded two-twisted pair with ground.
The shield should maintain continuity throughout the entire network and should be grounded at a single
end, usually the communication master end.
