4.5.1 MS/TP Specifications for Alternate Cable Solutions
1. An MS/TP (EIA-485) network shall use shielded, twisted-pair cable with characteristic impedance
between 100 and 130
Ω
..
2. Distributed capacitance between conductors shall be less that 100 pF per meter (30 pf per foot).
3. Distributed capacitance between conductors and shield shall be less that 200 pF per meter (60 pF per
foot).
4. Foil or braided shields are acceptable. The maximum recommended length of an MS/TP segment is 1200
meters (4000 feet) with AWG 18 (0.82 mm
2
conductor area) cable.
5. The use of greater distances and/or different wire gauges shall comply with the electrical specifications of
EIA-485 for MS/TP cable requirements.
