Installation
Preparing your site
Note: The HDMI extender kit lets you extend your 4K30 video signals over a Gigabit
LAN network, beyond the typical cable length restriction of 330 ft. (100m) of Gigabit
network portals.
Refer to the manufacturer of the network equipment to determine the length
restriction and to ensure the transmitter unit and receiver unit(s) are all within the
restricted range of the nearest network portal.
Note: Ensure the transmitter unit, and receiver unit(s) are all situated near AC electrical
outlets.
1. Determine where the local video source will be located and set up the transmitter
near that location.
2. Determine where the remote display will be located and set up the receiver near
that location.
3. (Optional) If you’re using additional displays, determine where they will be located
and set the additional receiver unit(s) near that location.
Hardware installation
Video wall or point to multi-point installation with a Gigabit LAN network.
1. Install the transmitter unit.
a) Connect your video source to the transmitter’s video input port.
b) Connect the transmitter’s DC 9-12V power jack to an AC electrical outlet, using one
of the included power adapters.
c) (Optional) If you intend to add a separate 3.5 mm audio source that can be
embedded into the HDMI signal and selected as the audio source, connect a 3.5
mm audio cable to your audio source device and to the transmitter’s analog audio
source port.
2. Install the receiver unit(s).
a) Connect a display to the receiver unit’s video output port using an HDMI cable.
b) Connect the receiver unit’s power jack to an AC electrical outlet, using one of the
