RS-422/485 CABLE SPECIFICATIONS
The following cables are recommended for RS-422/485 serial communications. Although you may elect to use other
cables, keep in mind that low capacitance (less than 15 pF/ft.) is important for high-speed digital communication
links. The cables listed below are all 24-gauge, 7x32 stranded, with 100-ohm nominal impedance and a capacitance
of 12.5 pF/ft.
Select from the following four-, three-, and two-pair cables, depending on your application needs. All will yield
satisfactory results. It is recommended that you choose a cable with one more pair than your application requires.
Use one of the extra wires, rather than the shield, for the common.
