Preparing your site
Note: The ST12MHDLAN HDMI extender kit can use a Gigabit LAN Network to
extend the signal. Most Gigabit Network portals have a cable length restriction of
330 ft. (100m). Refer to the manufacturer of the equipment to determine the length
restriction and ensure the Transmitter Unit, and Receiver Unit(s) are all within the
restricted range of the nearest network portal.
Ensure the Transmitter Unit, and Receiver Unit(s) are all situated near an available AC
electrical outlet.
1. Determine where the local video source (i.e. computer, Blu-ray Player) will be
located and set up the device.
2. Determine where the remote display will be located and place/ mount the display
appropriately.
3. (Optional) If using additional receiver units (ST12MHDLANRX sold separately),
determine where the remote displays will be located in and place/ mount the
displays appropriately

Hardware installation
Video wall or point to multi-point installation with a Gigabit LAN network
1. Install transmitter unit
a) Position the Transmitter Unit near the video source (i.e. Computer,
Blu-ray Player).
b) Connect an HDMI cable from the video source device (i.e. computer, Blu-ray
Player) to the “Video In”port on the Transmitter Unit.
c) Connect the provided Transmitter Unit power supply.
2. Install receiver unit(s)
a) Position the Receiver Unit(s) near the video display (i.e. television, projector).
b) Connect an HDMI cable from the display Input to the “Video Out” port on the
Receiver Unit.
c) Connect the provided Receiver Unit power supply.
d) (optional) If using additional ST12MHDLANRX Receivers (sold separately),
repeat steps for each additional Receiver.
Note: The“Dip Rotary Switch” on the transmitter and each receiver
connected to the network must be set in the same position for the devices
to communicate.
3. Connect the devices to a Gigabit LAN network
1. Connect an RJ-45 terminated Cat5e/6 Ethernet cable to the “LAN Port” (RJ-45
Connector) on the Transmitter unit, and all receiver units.
Note:
If you are using surface cabling, ensure you have enough Category 5e/6
unshielded twisted pair (UTP) network cabling to connect the Transmitter Unit to
the Gigabit LAN hub, router, or switch.
OR
If you are using premises cabling, ensure that the Category 5e/6 unshielded
twisted pair (UTP) network cabling between the Transmitter and Gigabit
LAN hub, router, or switch has been properly terminated in a wall outlet in each
location and there is a patch cable long enough to connect the Network portal
and Transmitter Unit to their respective outlets.

2. Connect the other end of the Cat5e/6 cable run to a Gigabit LAN hub, router
or switch.
Note: Your router must support IGMP snooping. Please refer to your network
switch or router documentation to ensure IGMP snooping is supported and
enabled.
3. (optional) When adding additional Receiver Units (ST12MHDLANRX – Sold
separately), a run of Cat 5e/6 cable will be required from each device to the
Gigabit LAN hub, router or switch.
4. Your source video image will now appear on the Receiver unit(s) attached video
display(s).

(Optional) Point to Point installation
without Gigabit LAN network
Note: While range is reduced to a maximum of 330 feet (100 Meters) the
ST12MHDLAN HDMI extender kit also allows for extending the signal without a Gigabit
LAN Network by connecting the Transmitter directly to the Receiver using CAT5e/6
cabling. This also eliminates the ability to add additional Receivers.
1. Install Transmitter Unit
d) Position the Transmitter Unit near the video source (i.e. Computer, Blu-ray Player).
e) Connect an HDMI cable from the video source device (i.e. computer, Blu-ray
Player) to the “HDMI IN” on the Transmitter Unit.
f) Connect the provided Transmitter Unit power supply.
2. Install Receiver Unit(s)
e) Position the Receiver Unit(s) near the video display (i.e. television, projector).
f) Connect an HDMI cable from the display Input to the“Video Out” port on the
Receiver Unit.
g) Connect the provided Receiver Unit power supply.
Note: The“Dip Rotary Switch” on the transmitter and Receiver connected must be
set in the same position for the devices to communicate.
3. Install RJ-45 terminated Cat5e/6 Ethernet Cable
4. Connect an RJ-45 terminated Cat5e/6 Ethernet cable to the HDMI Out Link (RJ-45
Connector) on the Transmitter unit.
Note: If you are using surface cabling, ensure you have enough Category 5e/6
unshielded twisted pair (UTP) network cabling to connect the Transmitter Unit
to the Receiver Unit’s location, and that each end is terminated with a RJ45
connector.
OR
If you are using premises cabling, ensure that the Category 5e/6 unshielded
twisted pair (UTP) network cabling between the Transmitter and Receiver Units
have been properly terminated in a wall outlet in each location and there is
a patch cable long enough to connect the Remote Unit and the Host Unit to their
respective outlets.
5. Connect the other end of the Cat5/6 cable run to the RJ45 connector on the
remote Unit Receiver Unit.

4. Your source video image will now appear on the remote unit(s) attached
video display.
Hardware Reset Procedure
Note: If video signal does not appear on the display a hardware reset can be
performed on the Transmitter Unit, or individual Receiver Units.
1. Press the reset button for more than 3 seconds on the device using a pin point tool,
such as a ballpoint pen or a bent paper clip.
