OPERATING MODE
The device can be used in two different switching modes :
• The SEAMLESS MODE,allowsswitchingseamlessly,fadingandtitlingbetweenthe“reference”COMPUTER
inputandtheotherinputs.Otherinputsarescaledtothesameformatasthe“reference”COMPUTERformat.
NOTE : Input #1 and #8 can be used as the reference capter input.
NOTE :The“reference”Computerisnotscaled.
• The FAST SWITCHING MODE allows selecting an output format corresponding to your application. All video
inputs are scaled to the selected format. The switching between two inputs will go through a fade colored tran-
sition.Theoutputratecanbeselectedbetween60Hz,75Hzorcanbesynchronizedtooneofthevideoinput

3-1. SETTINGS
1) We recommend resetting the device to its default values, with the LCD menu (CONTROL > Default value > yes)
before proceeding.
2) Select a switching mode with the LCD menu (SWITCHING > fast switching or seamless). Please see the
Switching mode table below.
3) Select the Auto settings function with the LCD menu (INPUT > Auto settings). This function will detect automa-
tically the source type connected to the inputs of the device. Sometimes, the auto setting may not detect the
source type : in this case select manually the source type with the LCD menu (INPUT > Input type).
4) If you have selected the fast switching mode : select one of the output formats with the LCD menu (OUTPUT >
output format).
NOTE : For xed pixels display devices (DMD, LCD, PLASMA…), always select the output format corres-
ponding to the native resolution of your device. Thus, the display device will not have to scale the image
and the result will be better.
NOTE : In SEAMLESS mode, the output format is the same as the “reference” computer format.
3-2. SWITCHING OPERATIONS
• The device allows 4 different switching effects : CUT*, FADE*, FADE COLOR and CLEAN CUT. The CUT effect allows
switching seamlessly between 2 sources. The FADE effect allows fading out the displayed source while another source
is fading in. The FADE COLOR effect allows switching between 2 sources with a fading through the color of you choice.
The CLEAN CUT allows a clean switching thanks to a fast freeze of the displayed source.
• PIP* = Picture in Picture is also available effect.
• OXE831 also enables you to key text onto the displayed image (TITLE* effect).
