REAR PANEL CONNECTIONS
Female RJ-45 100BASE-TX Ethernet receptacle for CAT-5 UTP cable.
Female DB-9 Provides serial bridge, RS-232 to Ethernet (requires host PC and straight-through cable)
Female BNC (x2): “Sync Output” provides word clock output and keep-alive signal for redundant operation.
“Slave Input” provides external word clock input and receives keep-alive signal for redundant
operation.
IEC male power receptacle: For AC lines power connection
