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. Like other INLINE interfaces, the IN2022HR performs the following functions: • Signal Splitting - allows the simultaneous connection and viewing of both the computer’s local monitor and a second output device such as an LCD data projec

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. Connect one of the connectors on this cable to the computer’s video por

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. GAIN CONTROL The gain control is a small black knob loc

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. In rare cases (depending on the design of the display device sync circuitry), operators may have to disable the horizontal position control to achieve a s

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

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. This allows

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
