5 Using the HDMI-Coax Transmitter/Receiver
You can use the 640T HDMI-Coax Transmitter and the 640R Coax-HDMI
Receiver to configure an HDMI-to-Coax Transmitter and Receiver system (see
Figure 3).
To connect the HDMI-to-Coax Transmitter and Receiver system as shown in
the example in Figure 3, do the following:
1. Connect an HDMI source, for example, the HDMI output from a Blu-ray
DVD player, to the 640T HDMI IN connector.
2. Connect the 640R HDMI OUT connector to the HDMI acceptor, for
example, a projector.
3. If using a 4-plug coax cable or 4 coax cables:
Connect the 640T red, green, blue, and clock BNC connectors to
the 640R red, green, blue and, clock BNC connectors
Connect 12V DC power supplies to both the 640T and the 640R
(not shown in Figure 3). The remote power and IR remote
control functions are not available
4. If using a 5-plug coax cable or 5 coax cables:
Connect the 640T red, green, blue, clock, and power BNC
connectors to the 640R red, green, blue, clock, and power BNC
connectors
Connect one 12V DC power supply to either the 640T or the
640R (not shown in Figure 3). Power and the IR remote control
function are transmitted over the power coax connection to the
second device
Note: All coax cables must be the same length. There can be no more
than 6 inches (15cm) difference in length between any of the
cables.
5. Connect the power supply(s) to the mains electricity.
After all connections are made and the units are powered ON, the system
operates.
