Operation
This section focuses on operating the IN1408 using the front panel controls and commands. All
adjustments, set-up functions and switching operations can be performed through the front panel or
remotely via RS-232 serial commands or the optional IR remote control. Information on using the
optional CTL120 IR remote can be found on page 41.
FRONT PANEL CONTROLS
Input Select: Selects the audio and video source. The large buttons labeled INPUT 1, INPUT 2,
INPUT 3, INPUT 4 INPUT 5, INPUT 6, INPUT 7, and INPUT 8 are used to select the desired
input. After turning on the IN1408, press and release the desired INPUT SELECT Button. A green
LED will light underneath the button to indicate the selected input. The stereo audio signal associated
with the input will automatically be selected at the same time. All audio, video and input settings for
each input are stored internally (in memory) so the adjustment(s) will not have to be repeated after
they are optimized. To switch to another input, simply press and release another numbered INPUT
SELECT Button.
Á Note: When powered up, the scaler automatically returns to the last configuration, including
the last input selected.
The BLANK Button can be used at any time to show a blank screen on the display device. When
blank is engaged, the output setting goes to black but the sync signals continue, ensuring that the data
display device retains sync lock. Simply press and release the button to engage blanking (the green
LED underneath the button will illuminate), and press and release it again to disengage.
Á
Note: The blank button has no effect on inputs 5 - 8 when they are configured as passive
inputs.
Freeze Frame: Allows users to freeze the video signal and display a still image. Simply press and
release the button to engage the function (the green LED below the button will illuminate), then press
and release again to disengage.
Á Note: The freeze button has no effect on inputs 5 - 8 when they are configured as passive
inputs
Volume: The volume buttons are used to regulate the level of the audio signals routed through the
scaler. Use the
¾ / ¿ volume buttons to increase / decrease the audio level for the current input.
Press and release a button to raise / lower the volume level by one step, or press and hold a button to
change the level continuously. Digital sound is a passive signal and can only be muted.

below the button will illuminate), and press again to disengage.
Menu Buttons: The remaining buttons on the front panel (MENU,
¾, ¿, ½, ¼ and ENTER) are
used to access and adjust the on-screen display menu. An illustration of the On Screen Display Menu
System is provided on the next page.
