ICW-STA
iCW-Net Wiring
Use Category 3 or Category 5 wire, 4 pair, unshielded, 24 AWG.
The iCC-HE and iCW-HE Head-End Network Controllers include three iCW-Net ports for
twisted-pair wired networking. Control wiring can be home-run to ports or run in a star format,
using punch-down blocks to distribute signals to multiple iCW-Net devices. Open wiring runs do not
need termination.
