  • Page 15 Input connectors — Connect HDMI source devices (or DVI sources with the appropriate adapters) to these female 19-pin type A HDMI input connectors. LockIt cable lacing brackets, one for each HDMI input and output connector, are provided with the DXP HD 4K PLUS. These brackets can be used to secure the HDMI cables to the DXP connectors to reduce stress on the HDMI connectors and prevent signal loss due to loose cable connections.
  • Page 16 Analog audio outputs — Connect powered speakers, an amplifier, or other audio output device to these 5-pole 3.5 mm captive screw connectors for 2-channel stereo analog audio output. These connectors can de-embed LPCM audio that was routed from any DXP HDMI input and convert it to a stereo analog signal. NOTE: Analog output 1 and S/PDIF output 1 are always connected to the video input tied to them.
  • Page 17: Connecting To The Lan Port

    Connecting to the LAN Port When connecting a computer to the DXP LAN port, it is essential that you use the correct Ethernet cables, and that they be properly terminated with the correct pinout (see figure 4). Ethernet links use Category (CAT) 3, 5e, or 6 unshielded twisted pair (UTP) or shielded twisted pair (STP) cables, terminated with RJ-45 connectors.

  • Page 81: Network Setup

    Network Setup What is an IP Address? An IP address is a 32-bit binary number that is used to identify each device on an Ethernet network. This number is usually represented by four decimal numbers (called “octets”), each in the range of 0 through 255 and separated by dots; for example, 198.123.34.240. This is called “dotted decimal notation.”...
