Operation, cont’d
IN1404XT Video Scaler and Switcher • Operation 3-20
Use the Menu button to highlight “Yes” and press the Enter (and save) button to
reset the RS-232 settings. Use the button to highlight “No” and press the Enter
button to exit the screen without resetting the RS-232 settings (or back out of the
screen by pressing the Menu button).
System Information screen
The System Information screen is an informational display only that shows:
• The selected input number
• The selected input’s sync format (RGBHV, RGBS, and so on) and resolution
• The selected input’s horizontal and vertical rates
• The output’s resolution
• The output’s horizontal and vertical rates
• The firmware version
Enabling seamless switching
When the scaler is in seamless switching mode, it uses input 4’s passive (unscaled)
synchronization signals as a reference for locking the output video signal. For
seamless switching to work properly, the following three conditions must be true:
• Input 4 must be set to be passively output without scaling.
• The output’s resolution, refresh rate, and sync format must be set to those of
the channel 4 input.
• The Input 4 reference must be within ±2% of the selected output resolution
and refresh rate.
When input 4 is passive, the scaler performs no decoding, scaling, or video
adjustment functions. Blank and freeze functions, and on-screen menus are
not available for input 4. The scaler functions as a switcher only for input 4.
Setting up seamless switching
Set the IN1404XT to seamlessly switch between scaled inputs on 1, 2, or 3 (RGB,
component, S-video, or composite video) and the passive RGB video on input 4 as
follows:
1 . Apply the RGBHV, RGBS, or RGsB reference to input 4.
2 . Press Menu and then select Output>Resolution, select the same resolution as
the input 4 reference signal, and press Enter (and save).
3 . While still in the Output screen, select Refresh Rate, select the same refresh
rate as the input 4 reference signal, and press Enter (and save).
4 . While still in the Output screen, select Sync Format, select the same sync
format (RGBHV, RGBS, or RGsB) as the input 4 reference signal, and press
Enter
(and save).
5 . While still in the Output screen, select Seamless Mode, select On, and press
Enter
(and save).
When you turn seamless mode on, the scaler automatically sets the input 4
signal format to passive if necessary.
When seamless mode is on, the scaler will not let you change the input 4 signal
format. To change the signal format, you must first turn seamless mode off.
Seamless switching operation
When seamless switching is on; and you switch to input 1, 2, or 3; that input is
synced to the input 4 reference. The synced input 1, 2, or 3 is termed the “channel
