2 Product Overview DESCRIPTION The IN2112R is a high-performance computer video interface for analog video signals including VGA, SVGA, XGA, MAC, Sun and other high-resolution workstations. The IN2112R combines high-resolution computer interfacing with two inputs, modular A/V connector plates and front panel A/C power outputs into a 2U rack mountable unit.
3 Front Panel A/C Power Outlets - The IN2112R has front panel power outlets (600 watts total) that provide a convenient place to plug in a laptop computer, CD player or other portable A/V device that will be located in front of the equipment rack.
4 down the unit when the input cable is removed. Auto monitor emulation emulates a VGA / MAC monitor when no local monitor is present. In addition the IN2112R features: • • • Analog Interface - the unit will operate with Analog Video with TTL level sync signals. The signal can be separate H & V or composite sync. Sync Polarity Preservation Switch - enables the sync polarity to be preserved, or to be set for negative polarity (for RGBHV signals in and out).
5 VGA, MAC, SUN, SGI and other high-resolution workstations operate in several video modes encompassing a wide range of resolutions and scan rates. Many of the video signals from the newest models can run as high as 70 KHz or more, with the newest VGA cards offering an output resolution of 1600 x 1200 (some can even go as high as 1920 x 1080).
6 Installation This section offers instructions for installing the IN2112R interface (see Application Diagram on page 7). 1. Utilizing the integral rack mounting ears, mount the unit in a standard 19” equipment rack (or larger) in a 2U space. Run the necessary video coax cable, power cabled any other audio, video, phone, data or control / accessory cables (if used) to the unit. 2. Set the dipswitches for the requirements of your installation (see Dipswitch Settings on page 9).
7 10. Connect the local computer monitor (if present) to the local monitor output of the IN2112R. VGA monitors will attach directly to the local monitor output. For other types of monitors, use the appropriate local monitor output adapter cable (see list on page 5). If no local monitor is used, set the monitor emulation dipswitch to emulate a color VGA monitor or a 13/14” MAC RGB monitor. 11. Connect the output of the computer to the input of the IN2112R with the appropriate input cable. 12.

9 IN2112R FRONT PANEL CONNECTORS AND CONTROLS HORIZONTAL POSITION CONTROL The location of the horizontal position control is shown above. The horizontal position control adjusts the position of the image on the data display device from left to right (it has no effect on the local computer monitor). Many data projectors and monitors have their own horizontal position control, and the interaction of the display devices and the interface’s horizontal controls may result in a dark image on the data display.
10 STEREO AUDIO SWITCHING The IN2112R provides stereo audio-follow-video switching to accommodate stereo audio signals from a computer audio card or other stereo audio sources. Whenever Input 1 or Input 2 is selected, the corresponding stereo audio signal is routed to the audio output connector on the back of the interface, which is normally connected to a house sound system. AUDIO INPUTS One 3.5mm female stereo mini jack is provided for each input.
11 DIPSWITCH SETTINGS Most installations will not require any changes to the dipswitch settings, and the IN2112R will generally be operated with the factory default settings. The Factory Default settings and specialized dipswitch settings are indicated below. Please note that when the interface is held upright, the dipswitches are numbered from 10 to 1 as shown below.

16 Troubleshooting The display device connected to the IN2112R output has a bad / scrambled image. Solution 1: Verify that the correct input cable is being used (see list on page 5). Solution 2: The display device connected to the output of the interface may not be compatible with the computer output. Standard 640 x 480 VGA runs at 31.5 KHz, and SVGA can be as high as 48 - 58 KHz, depending on the vertical refresh rate.
17 The output image is doubled, with two images displayed side-by-side. Solution: The display device may not be compatible with the horizontal scan rate of the computer. This problem often occurs when a 31.5 KHz VGA signal is sent into an RGB monitor that is only compatible with signals at 15.75 KHz. If problems persist, call INLINE Technical Services at (800) 882-7117 for further assistance. Warranty ♦ INLINE warrants the equipment it manufactures to be free from defects in materials and workmanship.
