This is the local unit for the NTI ST-IPHDMI-2G

The NTI ST-IPHDMI-L-2G HDMI Over Gigabit IP Extender multicasts digital video and audio signals to one or more receivers up to 333 feet away over a Second-Generation (2G) 1000BASE-T Gigabit Network connected with CAT5e/6/7 cable.

The NTI ST-IPHDMI-2G Gigabit IP Extender consists of the ST-IPHDMI-L-2G local unit that connects to an HDMI source, and the ST-IPHDMI-R-2G (not included) remote unit that connects to an HDMI display. The local and remote units can be connected together for a Point-to-Point connection via CATx or a Point-to-Many connection via a network switch. Support for multiple transmitters requires a managed network switch.

NTI ST-IPHDMI-L-2G Features and Benefits:

  • Supports HDTV resolutions to 1080p.
  • Ideal solution for digital signage applications.
  • Broadcast real-time HDMI video/audio to multiple display locations.
  • Transmits an HDMI signal over one CAT5e/6/7 cable.
  • Supports video wall installations from 1x2 to 8x8 screens.
  • Plug-and-Play installation allows receivers to find the transmitter automatically on the same network. (Network configuration may be required for Managed network switch.)
  • Easily expandable. Add remote units as you add monitors.
  • No image scaling, the original video signal that is input will be output at the source resolution.
  • Supports 2-way RS232 commands (control software on a PC, or other automated control system hardware such as Control4 or Crestron) to control any devices attached to the matrix using RS232.
  • Integrated mounting wings for ease of installation.
  • Inexpensive CAT5e/6/7 cable replaces bulky video cables.
  • Support for multiple transmitters requires a Managed network switch with VLAN/IGMP support. Standard LAN switches can only support one transmitter.
    • Each VLAN acts as a separate HDMI Over IP Channel on the network.
    • One transmitter can connect up to 200 receivers using cascaded managed network switches.
  • If a non-managed network switch is used for a point-to-many connection, it is not recommended to use other network devices on the same switch as it may cause a degradation in performance.
  • Use a PC to access the built-in HTTP Interface of the managed network switch to control what signal is being watched at each location.
  • Use a Telnet client to access any receiver on the VLAN or network.
  • Customizable EDID table on local unit.
  • HDCP compliant.
  • Local and remote units must be in the same LAN. The units do not support WAN connections.
