Preparing Your Site
1. Determine where the local video sources (i.e. computers, Blu-ray Players) will be
located and set up the device.

appropriately.
Note: Please ensure the Matrix switch and each Receiver is situated near an
available AC electrical outlet. Make sure all devices are turned o before beginning
installation.
Installation
Hardware Installation
1. Install Matrix Transmitter
a) Position the Matrix Transmitter near the video source devices (i.e. Computers, Blu-
ray Players).
b) Connect up to four HDMI cables (not included) from each of your HDMI video
source devices (i.e. computers, Blu-ray Players) to each of the HDMI input ports on
the matrix switch.
c) (Optional) If you intend to use local displays, connect up to 4 HDMI cables (not
included) from each local HDMI output port on the matrix switch to the HDMI input
ports on your local displays (i.e. televisions, projectors).
d) (Optional) If using the Extender kit to transmit an infrared (IR) device signal,
and the device receiving the IR signal is on the Receiver side. Connect the IR
Transmitter Cable (included with each STHDBTRX Receiver Unit) to the IR-Receiver
port that corresponds with remote device that being controlled on the Matrix
Unit, and position the extended IR sensor directly in front of the video source’s IR
sensor. Check the manual of your video source device for the IR sensor location.
If the device receiving the IR signal is on the Transmitter side, then connect the
IR Transmitter Cable (also included with each STHDBTRX Receiver Unit) to the IR-
Transmitter port that corresponds with the remote device that is being transmitter,
and position the IR sensor where the remote control will point.
e) Connect the power adapter from an available power outlet to the Power jack on the
Matrix switch.
2. Install RJ45 terminated Cat5e/6 Ethernet Cable
a) Connect up to four RJ45 terminated Cat5e/6 Ethernet cables (not included) to each
of the Cat5 output ports on the Transmitter unit.

Instruction Manual

Note: If you are using surface cabling, ensure you have enough Category 5e
unshielded twisted pair (UTP) network cabling to connect the Matrix switch
to the Receiver Unit’s location, and that each end is terminated with a RJ45
connector. The cabling should not go through any networking equipment (i.e.
router, switch).
OR
If you are using premises cabling, ensure that the Category 5 unshielded twisted
pair (UTP) network cabling between the Host Unit and the Remote Unit has 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. The cabling should not go through any networking equipment (i.e. router,
switch).
b) Connect the other end of each Cat5e/6 cable run to the Link port (RJ-45 Connector)
on the connector on the remote STHDBTRX Receiver Units (sold separately).
3. Install STHDBTRX Receiver Units (sold separately).
a) Position each Receiver Unit near the video display (i.e. television, projector).
b) Connect an HDMI cable (not included) from the Receiver unit to the video input
port on the remote display device (i.e Television/Projector).
c) (Optional) If using the Matrix switch to transmit an infrared (IR) device signal,
and the device receiving the IR signal is on the Transmitter side. Connect the IR
Transmitter Cable to the IR-Transmitter port on the Receiver unit, and position the
IR sensor where the remote control will point. If the device receiving the IR signal
is on the Transmitter side, connect the IR Receiver Cable to the IR-Receiver port,
and position the extended IR sensor directly in front of the video source’s IR sensor.
Check the manual of your video source device for the IR sensor location.
d) Connect the power adapter from an available power outlet to the power jack on the
Receiver unit.
e) Repeat these steps for each STHDBTRX Receiver Unit.
4. (Optional For remote serial control) Connect a straight through DB9 serial
cable (not included) from the LAN port on the back of the ST424HDBT to
your network device (Router/Network Switch/PC.
5. (Optional For remote IP control) Connect a CAT5e/6 cable (not included)
from the LAN port on the back of the ST424HDBT to an available COM port
on your computer.
6. Hardware installation is now complete.
