Power on Adjustments, Reset to Factory Defaults

POWER ON ADJUSTMENTS

The IN1222 / IN1510 / IN1422 / IN1710 utilize "Power On" settings to control two setup parameters. In order to access a Power On adjustment, the user must hold down the indicated button continuously while toggling the unit’s power switch to "ON" (if power is already on, the user can hold down the indicated button and switch the power off and then back on).

Reset to Factory Defaults

The IN1222 / IN1510 and IN1422 / IN1710 offer a powerful set of controls for adjusting video and audio parameters. If the set-up technician or users have changed several of the parameters and want to get back to average settings, the simplest way is to reset the unit to the factory default settings.

Reset to Factory Defaults: Hold down the VIDEO 1 Channel Select button while turning power on. This resets the video / audio adjustments for all input channels to factory default settings:

Video / Audio:	All adjustment parameters set to factory defaults (average settings)
Channel Selection:	Input 1 Selected (Input 1 is selected each time the power is turned on)
Video / S-Video:	S-Video selected for all input channels
Gamma:	Gamma Curve 0 (no Gamma Correction)
SECAM:	SECAM disabled (unit automatically decodes NTSC or PAL)
Scan Doubling:	Enabled (IN1222 / IN1422 only)
Doubling Mode:	Line Doubling (IN1222 / IN1422 only)
Baud Rate:	1200
Command Codes:	[ ]

Output Sync Format is not effected by the Power On "Reset to Factory Defaults."

Output Sync Format can only be changed by using the Power ON settings described in the paragraph below or by using RS-232 commands (see page 19).

Select Output Sync Format

The IN1222 / IN1510 / IN1422 / IN1710 feature flexible output sync format capability. This allows users to select an output video format which meets the needs of both the video switching / distribution system and the display device. Users who wish to emulate a standard 640 x 480 VGA signal should select the factory default output format, which is RGBHV with negative sync polarities.

Holding down the appropriate button at Power On will change the output signal to the desired format:

Output Sync Format	Hold Down Button at Power On
RGBHV(++)	VOLUME UP
RGBHV(--)	HUE UP
RGBS	COLOR UP
RsGsBs	CONTRAST UP
