FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

Why is 9463 universally known as 'Blue Hose' in industrial automation?
Its signature bright blue PVC jacket and 78 Ω twinaxial construction (1 blue core, 1 clear core, plus a separate 20 AWG tinned drain wire) were standardized by Rockwell Automation / Allen-Bradley for Data Highway Plus (DH+) and Universal Remote I/O (RIO) networks.
What are the maximum trunk lengths and termination resistors for DH+ and Remote I/O?
At 57.6 kbps, 9463 supports 3,048 m (10,000 ft) with 150 Ω termination resistors; at 115.2 kbps, 1,524 m (5,000 ft) with 150 Ω resistors; and at 230.4 kbps, 762 m (2,500 ft) using 82 Ω termination resistors.
Can standard 100 Ω Ethernet or 120 Ω RS-485 cable substitute for 78 Ω 9463?
No. DH+ and Remote I/O transformer-coupled transceivers are tuned to 78 Ω ± 3 Ω and 64.6 pF/m; substituting 100 Ω or 120 Ω cable causes impedance reflections and communication drops on trunks over a few hundred meters.
Is there an avionics 78 Ω twinaxial counterpart to 9463?
Yes. While 9463 is the 20 AWG PVC industrial bus cable, MIL-STD-1553B (M17/176-00002) is the fluoropolymer 78 Ω twinaxial cable qualified for -55 °C to +200 °C airborne command/response data buses.
