USB DVI KVM Console Extender w/ Serial & Audio Over MM Fiber - 2km

Digital Visual Interface (DVI) is a video display interface that can contain different types of signaling, based on the application. DVI cables and ports are created using different connector types to identify what application they are intended to be used in. The connector types are identified by the number of pins on the DVI connector. DVI comes in the following five different connector types: 

• DVI-A (17 pin).
• DVI-D Single Link (19 pin).
• DVI-D Dual Link (25 pin).
• DVI-I Single Link (23 pin).
• DVI-I Dual Link (29 pin).

Single and Dual link DVI indicate the maximum resolution capabilities of the video source or video destination. The maximum resolutions are Single Link (1920 x 1080 @ 60Hz) and Dual Link (2560 x 1600 @ 60Hz).

Note: The maximum resolution of your video source and video destination are ultimately determined by the technical specifications of the devices. The connector type is not a definitive indicator of the maximum resolution.

DVI-A carries only analog (for example, VGA) with no digital component. DVI-D carries only digital video (for example, HDMI) with no analog component. DVI-I combines DVI-A and DVI-D connections to include both analog and digital components. A DVI-I port may be on either your video source or display, but whether or not a display carries either or both analog and digital sources depends on the technical specifications of your device.

Different optical cables are needed for different applications. Before you select a cable to interconnect fiber devices, make sure that the following things match:

• Mode: Single Mode or Multi Mode.

• Wavelength: For example, 850 nm, 1310 nm, or 1550 nm.

Note: The above properties cannot be converted or changed by a cable.

When you select a cable, make sure that the cable ends (for example, LC, SC, ST, or MT) match the fiber media devices.

Simplex and duplex ends are available for most connector types. Simplex cables have the connectors separate, where duplex cables have the transmit (TX) and receive (RX) connectors joined together.  

It does not matter which diameter or OM classification the cable uses, as long as it meets the mode requirement.

When you use fiber devices and cables, make sure that the same fiber standards are being used on either end of the fiber network.

This device has a DVI-I connector, but is only compatible with digital DVI video signaling. For more information about the different DVI connectors, refer to the following FAQ: https://www.startech.com/faq/video_signal_converters_dvi_interface

If the keys on your keyboard are repeating, complete the following:

1. If the KVM you are using has USB ports, you can move your keyboard to the USB hub port on the back of the KVM (the USB hubs are marked).

Note: When you move the keyboard out of the keyboard port, you will not be able to access the hotkeys.

2.  You can adjust the typematic rate in your operating system’s settings. Depending on the version of Windows you are running, you can adjust the typematic rate by doing one of the following:
   • Click Control Panel > Keyboard > Speed. Adjust the repeat delay and repeat rate until the keys no longer repeat.
   • Click Control Panel > Hardware and Sound > Devices and Printers. Right-click Keyboard Settings. Adjust the repeat delay and repeat rate until the keys no longer repeat.

There are some quick tests that you can complete to rule out potential issues. You can test to make sure that the following components are working correctly and are not the source of the issue:

• Video and Ethernet cables
• Mouse and keyboard
• Video source (such as a DVR or computer)
• Video destination (such as a monitor or projector)

Note: When you test setup components, you should avoid using video adapters. For example, if you are converting a VGA source to HDMI for use with an HDMI extender, you should use an HDMI source when you test the components.

To test your setup components, try the following:

• Use a different cable, mouse, keyboard, video source, and video destination in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.
• Use the cable, mouse, keyboard, video extender, video source, and video destination in another setup to see if the problem is with the components or the setup.

When you test your cables, it is recommended that you do the following:

• Test each cable individually.
• Use short cables when you are testing.

When you test the video source and video destination, it is recommended that you do the following:

• Test to make sure that the video source and video destination work together without using the KVM extender.
• Test to make sure that the video source and video destination work together at the resolution that you want to use.

Note: In order for your setup to work properly, the video source, extender, and destination all need to support the resolution that you are using.
