Chapter 1: Specifications 1. Specifications 1.1 Interfaces 1.1.1 DVI-D Single Link The video interface supports the DVI-D protocol. All signals that comply with the DVI-D Single-Link specification can be transmitted. This includes, for example, monitor resolutions such as 1920 x 1200 @ 60 Hz, Full HD (1080p), or 2K HD (up to 2048 x 1152). Data rate is limited to 165 Megapixels per second. 1.1.2 DVI-I Single Link The video interface supports the DVI-I protocol.
Chapter 1: Specifications When handling, take care not to damage devices. 1.1.7 Serial Interface The serial interface option supports a full-duplex transmission with a real hardware handshake up to a baud rate of 19,200. The CON module is cabled as DTE (Data Terminal Equipment, such as CPU output) and can be connected directly to DCE (Data Communication Equipment) devices. • A touchscreen can be connected directly to the CON module.
Chapter 1: Specifications • The output of the CPU module is connected to the audio input of the sound card (blue). Choose this connection if the microphone has its own pre-amplifier. NOTE: The CON module can do the pre-amplification of the microphone as well. Open the CON module, locate the “MIC” jumper on the audio board and close the pins. Table 1-2.

Chapter 2: Overview 2. Overview 2.1 Application The DKM Modular Extender is used to increase the distance between a source (computer, CPU) and its console (keyboard, mouse, and other peripheral devices). It’s designed for use with CATx (twisted-pair) interconnect cables or fiber interconnect cables. The DKM Modular Extender with CATx interconnect cables won’t work between buildings where you should use a fiber optic based product instead.

Chapter 4: Configuration 4. Configuration 4.1 Transmission Parameters The device operates with a proprietary compression method. In its default configuration, the device adapts dynamically to monitor resolution and image content. This configuration works in almost all conditions. Modify it only if image quality is not fully satisfactory. NOTE: In exceptional cases, detached "frame droppings" (loss of single pictures) or color effects can appear. 4.

Keyboard Sequence Description + Press keys simultaneously , Press keys successively 2x Press key quickly, twice in a row (similar to a mouse-click) You can change the hotkey sequence to enter Command Mode. Table 4-3 lists the hotkey codes for the available key sequences. Table 4-3. Hotkey Sequences.
Chapter 5: Operation 5. Operation Download of DDC Information By default, data from the internal DDC list is reported to the source (computer, CPU). If these settings do not lead to a satisfying result, you can download and store the console monitor’s DDC information internally. The devices must be configured accordingly (see Section 4.2). On all KVM Extenders with USB-HID support, the user can load the DDC information of the console monitor via keyboard command under operating conditions. 1.
