4 Connecting the VP-420, VP-421
Always switch off the power to each device before connecting it to your
VP-420, VP-421. After connecting your VP-420, VP-421, connect its
power and then switch on the power to each device.
To connect the VP-420, VP-421 as illustrated in the example in Figure 3:
1. Connect a computer graphics or HDTV source to the PC/HD INPUT 15-pin
HD connector.
2. Connect to the PC/HD OUTPUT 15-pin HD connector to a computer
graphics or HDTV acceptor as follows:
When connecting to an XGA acceptor (RGBHV), connect to the
acceptor’s XGA connector
When connecting to a component acceptor (YPbPr), connect as shown
here:

3. If connecting a VP-421, connect the DVI OUTPUT to a DVI acceptor.
The VP-421 outputs on both the 15-pin HD connector and the DVI connector. You can
connect to either output or to both of them simultaneously.
4. Connect the 5V DC power adapter to the power socket and connect the
adapter to the mains electricity (not shown in Figure 3).
