How to Install
The length statements in the tables above are valid for bus cable with the following properties:
-Impedance: 135 to 165 Ohm at a measuring frequency from 3 to 20 MHz
-Resistance: <110 Ohm/km
-Capacitance: <30 pF/m
-Damping: max. 9 dB over the whole wire length
-Cross section: max. 0.00053 in2 [0.34 mm2], corresponding to AWG 22
-Cable type: twisted in pairs, 1 x 2, or 2 x 2, or 1 x 4 wires
-Shielding:
Use of the same cable type throughout the entire segment is recommended to avoid impedance mismatch.
