CABLE RECOMMENDATIONS
Ethernet
For Ethernet communications, use Category 5 UTP (unshielded twisted pair) cable.
Serial
For serial communications, Opto 22 recommends the following cables for use with the SNAP-LCM4. Although
you can use other cables, keep in mind that low capacitance (less than 15pF/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.
It is recommended that you choose a cable with one more pair of wires 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)
•

Three-Pair:
•
Belden P/N 8103 (with overall shield)
•
