The communication of fiber devices is performed via Gigabit SFPs that have to be connected to suitable fibers fitted with type LC connectors (see Chapter 1.2.2). NOTE: The correct function of the device can only be guaranteed with SFPs provided by Black Box. CAUTION: SFP modules can be damaged by electrostatic discharge (ESD).
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.
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.

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.
