Advanced Operation
PASS-THROUGH RGB VIDEO
Inputs 5 - 8 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 IN1408, the selected output will appear at
both the 5 BNC and the 15-Pin HD (VGA) video outputs.
Key Concept
Once you have set Input 5, Input 6, Input 7 or Input 8 for RGB passive mode, the IN1408 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, Input 2, Input 3 or Input 4 (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 5, Input 6, Input 7 or Input 8, and then select the desired signal format.
Once this change has been made, the proper signal format will be displayed whenever Input 5, Input
6, Input 7 or Input 8 is selected (via the Input Select Buttons).
Á
Note: 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 IN1408 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
RGB Input / Output Installation Cables Chart on page 43).
OUTPUT MODES
The IN1408 supports the following Output Modes:
Refresh Rate (Hz)
Resolution Mode Aspect Ratio* 56 60 65 72 75 85 96 100 120
640 x 480 VGA 4:3

852 x 480 HDTV - 480p 16:9
1024 x 768 XGA 4:3
1152 x 864 4:3
1280 x 720 HDTV – 720p 16:9

1280 x 1024 SXGA 5:4
1365 x 768 Wide XGA 16:9

Blank, freeze, the on screen menu and other video functions are not available
for Inputs 5 - 8 when set to RGB passive mode.
