3. Product Overview
3.3.7. Control Ethernet Port
The matrix contains an RJ-45 connector for Ethernet/
LAN connection for local control functions.
The Ethernet ports can be connected to a LAN hub, switch or
routerby a CATx cable. However both cable types (straight or cross)
are supported and handled by the device, below pin assignment is
recommended.
Wiring of LAN Cables
Lightware recommends the termination of LAN cables on the basis of
TIA/EIA T 568 A or TIA/EIA T 568 B standards.
