Connecting External Equipment
Making the Connection to a Computer
To make the connection to a computer, carry out the steps described below.
1. Connect a computer.
After starting the V-4EX and the operating system on the computer, use USB cable to connect the USB port on the V-4EX to a USB
port of your computer.
Making the connection through an extension cable or USB hub may result in failure of the computer to detect the V-4EX. We recommend
connecting the V-4EX and computer directly.
2. Wait for communication between the V-4EX and the computer to be established.
A short while after making the connection, communication with the computer starts, and the standard driver for the operating
system is automatically installed. Installing a special driver is not necessary.
* The computer recognizes the V-4EX as a USB video class device/audio class device.
Performing Output to a Computer
For the video and audio signals from the V-4EX to be viewed and heard correctly on the computer, software that supports USB
video class and USB audio class must be installed and set up on the computer.
1. Prepare output of video or audio.
Operate the V-4EX to prepare the video and audio output for the computer.
2. On the computer, check the input from the V-4EX.
Start the program that supports USB video class/audio class, and check the video or audio input from the V-4EX.
You can use the menus to adjust the volume/balance of the audio output (p. 36) or delay its timing to sync with the video (p. 37).
Output Signals
The following signals are output from the USB port on the V-4EX.
Video 720 x 480 pixels (when set to NTSC) or 720 x 576 pixels (when set to PAL)/Motion JPEG
