Cable Wiring
Cables used for connecting a 2001 Router RS-485 serial port to the
console’s XY Controller are a high quality dual twisted pair cable
suitable for extended distance data transmission. A cable with an
impedance of 125 ohms and nominal capacitance of 12.8 pF/ft @1
MHz is recommended. See cable specifications and pinouts for details.
