5.1. SELECTING THE OUTPUT SIGNAL FORMATS
When the 2430DAC is operating in the single link 4:2:2 mode, (DIP switch 6 Off) DIP switches 1 to 4 are
used to select the combination of output signals present on the video output connectors as shown in Table
5-2. When using the VGA output mode, the VGA monitor must have sufficient resolution and vertical
resolution to display the input video. Table 5-3 shows the minimum VGA monitor requirements for each
video format supported by the 2430DAC-HD.
