Advanced Operation
Pass-through RGB video
Inputs 3 and 4 can be set for RGB passive video. No decoding, scaling or video adjustment functions
are available when these inputs are set for passive format. In passive mode, the unit merely acts as an
RGB switcher. Since there is a distribution amplifier built into the IN1404, the selected output will
appear at both the 5 BNC and the 15-Pin HD (VGA) video outputs.
Blank, freeze, the on screen menu and other video functions are not available for input 3 and input
4 when set to RGB passive mode.
Once you have set input 3 or input 4 for RGB passive mode, the IN1404 is functioning as a passive
switcher and you will not be able to see any on-screen menus. If you wish to select a different input
mode following this procedure:
1. Select input 1 or 2 (use the front panel Input Select buttons). The main menu will become
available.
2. Using the front panel MENU buttons, select input, followed by signal format.
3. Select input 3 or 4, and then select the desired signal format.
Once this change has been made, the proper signal format will be displayed whenever input 3 or 4 is
selected (via the
Input Select buttons).
Audio is an active function, and all audio functions are still available, even though the menu
cannot be displayed.
Output RGB connectors
The dual RGB outputs of the IN1404 are individually buffered (including RGB passive signals). They
may both be connected simultaneously without degradation of the other output. Both are capable of
transmitting the RGB signal over 100 feet or more through high quality coaxial cables (see the
Cables
chart on page 41).
Output modes
The IN1404 can be set to output any of the following resolutions and refresh rates:
Refresh Rate (Hz)
Resolution Mode Aspect Ratio* 56 60 65 72 75 85 96 100 120
640 x 480 VGA 4:3
800 x 600 SVGA 4:3
852 x 480 HDTV - 480p 16:9

1280 x 1024 SXGA 5:4
1365 x 768 Wide XGA 16:9
1365 x 1024 4:3
* The length versus the height of the output image determines the output aspect ratio.
