Selection Notes (Engineering Tips)
Match 120Ω impedance – avoid signal reflection
Terminate both ends – use 120Ω resistors on the first and last nodes
Ground drain wire at one point only – prevents ground loops
Keep distance from power cables – minimum 300mm separation
Observe bend radius – 10× cable OD minimum
Max 32 nodes – use repeaters for more
Cable length vs. baud rate – longer runs = lower speed
Avoid outdoor use – rated for -20°C to +75°C, indoor only
