Crimp Replacement LAN Cables
You can crimp your own LAN cables for use with the NCS. Use a cross-over cable when connecting an NCS
to a hub, LAN modem, or switch, and use a LAN cable when connecting an NCS to a router or workstation.
Use CAT-5 cable RJ-45 T-568B, Color Code (100 Mbps), and a crimping tool. Figure 11: RJ-45 Pin Numbers,
