5 Connecting the 640T/640R
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 ).
Always switch off the power to each device before connecting it to your
640T/640R. After connecting your 640T/640R, connect its power and
then switch on the power to each device.
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.
