Power and A/V Wiring: In this example the A 6500 wall plate is located at the lecturn and the A 6505 Relay Hub is situ-
ated in the ceiling space where power for the realy hub, projector and projector screen are located. The A 6500 Wall Plate
is powered through the single Cat5/6 cable connected back to the A 6505. The laptop and DVD player are situated and
powered at the lecturn and their corresponding VGA and HDMI output cabling is connected back to the projector.
Control Wiring: The projector is controlled by RS232 commands from the A 6505 serial output 1, the projector screen is
controlled by RS232 commands from the A 6505 serial output 2. The RS232 control cabling requires only the TX and GND
connection from the A 6505 and the RX and GND connection at the projector and projector screen. The DVD player is
controlled by IR codes sent from the A 6505 to an IR repeater. The lighting is controlled by the relay outputs of the A 6505
which are voltage free closing contacts. Figure 8 cable would be suf cient for all of these connections.
