Introduction
The ST121WHD Wireless Video, Audio and IR Extender lets you connect a remote
HD display or projector up to 30m (100ft) away from the HD source wirelessly. The
ST121WHD is a bundled kit that includes both a local and a remote unit providing a
complete end to end solution for a single source to display connection. This wireless HD
extender eliminates the need for expensive cable infrastructure, and provides a wireless
solution where cabling is undesirable, i.e. in the middle of a room, or boardroom.
The Wireless HD extender kit is compliant with WHDI and HDCP standards, ensuring
even the latest devices will be able to pass a signal with support for full 1080p
resolutions and the accompanying digital audio. Control your source device remotely
using the IR extender for a complete HD extension solution.
The kit includes the transmitter and receiver units for a cost-eective, ready-to-use
digital signage solution.
Backed by a StarTech.com 2-year warranty and free lifetime technical support.

Preparing Your Site
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.
Notes: This product includes optional bases allowing for horizontal or veridical
positioning. It is recommended that both the Transmitter Unit and the Receiver
Unit be positioned in the same fashion. If for example the Transmitter Unit
is placed vertically and the Receiver Unit is positioned horizontally the image
transmission distance may
be compromised.
The maximum distance between the transmitter and the receiver is 30 meters. If
the wireless signal is obstructed by walls, or other interference the signal quality
and maximum distance will likely be reduced.
Ensure the Extender Unit and the Receiver Unit are situated near an available AC
electrical outlet.
Hardware Installation
1. Installation of Transmitter Unit
a) Position the Transmitter Unit near the video source (i.e. Computer,
Blu-ray Player).
Note: If the Transmitter Unit is positioned vertically, ensure the built-in antenna is
facing upwards
Instruction Manual

b) (Optional) If using the ST121WHD to extend an infrared (IR) device signal.
Connect the IR remote extension connector to the IR remote signal output
port on the Transmitter 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.
Note: This product can only supports an IR signal in 38 kHz carrier
modulation mode.
c) Connect the provided Transmitter Unit power supply.
d) Connect the video source to the HD port on the rear panel of the Transmitter
Unit, using the provided male/male HD cable.
2. Installation of Receiver Unit
a) Position the Receiver Unit near the video display (i.e. television, projector).
Note: If the Receiver Unit is positioned vertically, ensure the built-in antenna is
facing upwards. If an infrared (IR) device is being used direct the IR signal toward
the IR sensor.
b) Connect the provided Receiver Unit power supply. The wireless network
status indicator will turn on after a successful wireless connection between
both units is established. This may take several seconds.
c) Connect the video source to the HD port on the rear panel of the Receiver
Unit, using a male/male HD cable (Not included).
d) The video source will now be displayed on the remote receiver.

Trouble Shooting
1. Improve Signal Quality
Environments with large amounts of 5GHz wireless trac (such as an oce), DFS1
(5150-5250 MHz -non DFS band) and DFS4 (5725-5850 MHz-non DFS band) should be
disabled by setting to ON in the Advanced Settings to yield better performance.
a. Using the IR remote control, Press MENU- > Select Advanced Settings -> DFS 1 to
change to ON. The unit will restart when completed.
b. Repeat step (a) this time selecting DFS 4 to ON. The unit will restart when
completed.
Note: OFF indicates the band is enabled. ON indicates the Band is disabled. For
reference the frequencies of each band option is listed below.
Frequency Table
DFS 1 5150-5250 MHz (non DFS band)
DFS 2 5250-5350 MHz (DFS band)
DFS 3 5470-5725 MHz (DFS band)
DFS 4 5725-5850 MHz (non DFS band)
