CABLE AND CONNECTOR
SPECIFICATIONS
SERIAL COMMUNICATION CABLES
The following cables are recommended for both RS-232 and RS-485/422 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 two-, three-, and four-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.
Two-Pair:
•
Belden P/N 8102 (with overall shield)
•
Belden P/N 9729 (individually shielded)
•
Belden P/N 8162 (individually shielded with overall shield)
•
Manhattan P/N M3475 (individually shielded with overall shield)
•
Manhattan P/N M39249 (individually shielded with overall shield)
Three-Pair:
•
Belden P/N 8103 (with overall shield)
•
Belden P/N 9730 (individually shielded)
•
Belden P/N 8163 (individually shielded with overall shield)
•
Manhattan P/N M3476 (individually shielded with overall shield)
•
Manhattan P/N M39250 (individually shielded with overall shield)
Four-Pair:
•
Belden P/N 8104 (with overall shield)
•
Belden P/N 9728 (individually shielded)
•
Belden P/N 8164 (individually shielded with overall shield)
•
Manhattan P/N M3477 (individually shielded with overall shield)
•
Manhattan P/N M39251 (individually shielded with overall shield)
