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 or RJ-45 “harmonicas” to distribute signals to multiple iCW-Net devices. Open 
wiring runs do not need termination.
