IN2022HR HIGH RESOLUTION VGA & MAC INTERFACE IN2022HR OPERATION MANUAL
Installation and Safety Instructions For Models without a Power Switch: The socket outlet shall be installed near the equipment and shall be accessible. For all Models: No serviceable parts inside the unit. Refer service to a qualified technician. For Models with Internal or External Fuses: For continued protection against fire hazard, replace only with same type and rating of fuse.
1 Product Overview DESCRIPTION The IN2022HR is a high performance, dual function, computer video interface for VGA and MAC-type video signals. The unit features a permanently attached, dual-headed input cable, optimized for high-resolution signals.
2 Convenient Controls - offer intuitive one-touch command capability over the most important signal adjustments. • Gain Control - adjusts the voltage level of the RGB components simultaneously (ensuring that gray scale is maintained), and may be used to compensate for signal loss due to long cable runs. • Sharpness Control - provides effective image enhancement for high-resolution video signals by increasing clarity and edge detail.
3 Installation This section offers step-by-step instructions for installing the IN2022HR. An Application Diagram is provided on the following page. 1.) Turn the Computer and Computer Monitor Off - Disconnect the monitor from the computer’s video port. 2.) Connect the IN2022HR Input Cable - to the computer’s video output port. The input cable is the 4’ long “Y” cable permanently attached to the interface.

5 Front Panel Controls The IN2022HR features fully automatic operation, however, the interface offers several external controls that allow users to optimize the unit’s performance to meet the needs of specialized applications. Gain, sharpness and horizontal position control adjustments are located on the front of the IN2022HR. Turning the adjustments clockwise will increase the value, and counterclockwise will decrease it.
6 1. Set the display device’s horizontal position control to the center of its adjustment range. 2. Adjust the horizontal position control on the IN2022HR until the picture is centered properly on the display device. Horizontal Position Control Enable / Disable - The factory default setting is horizontal position control enabled.
7 OUTPUT SIGNAL FORMAT SELECTION Automatic Sense Mode - In the factory default configuration, the IN2022HR automatically senses the number of cables connected to the output BNC connectors and selects the appropriate output signal format. LED indicators located next to the V/Sync, H/Comp Sync and Green output BNCs (on the back of the interface) provide clear visual confirmation of the current output sync format. In order for output format auto sense circuit to operate, dipswitch 5 must be set to 1.
8 Using the IN2022HR with a Local Monitor - Many high-resolution graphic workstations use sense signals to set resolution, horizontal frequency and vertical refresh rate. The IN2022HR passes all sense pins between the computer video port and the Local Monitor, ensuring that the computer can sense the attached monitor and set itself to an appropriate resolution and scan rate for that device. The Monitor Emulation dipswitches must all be set to “0” when using a local monitor.

12 Problem: A laptop is connected to the IN2022HR input. The display device connected to the IN2022HR main output (5 BNCs) is not showing an image. Solution 1: All monitor emulation dipswitches must be set and all connections must be made before powering up the laptop. This tells the laptop to make the video port active. Solution 2: The laptop’s video port may require a keystroke to make the video port active. Many laptops have a key with a monitor shaped icon that activates the external video port.
