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-effective, ready-to-use digital signage solution.

Backed by a StarTech.com 2-year warranty and free lifetime technical support.

Packaging Contents

• 1x Wireless HD Transmitter
• 1x Wireless HD Receiver
- 2x Positioning Stand
- 1x HD Cable
• 1x IR Remote Extension Connector
• 2x Universal Power Adapter (NA/UK/EU)
• 1x Instruction Manual

System Requirements

• HD enabled video source device (i.e. computer, Blu-ray Player)
• HD enabled display device (i.e. television, projector)
• Available AC electrical outlet for transmitter and receiver
• HD cable from receiver to display (HD cable from video source to transmitter is provided)

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).

Built-in Antenna

Note: If the Transmitter Unit is positioned vertically, ensure the built-in antenna is facing upwards

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.

Built-in Antenna 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.

1. Using the IR remote control, Press MENU -> Select Modify Video Source Name
2. Using the cursor select a name that better suits specific transmitter.

Trouble Shooting

1. Improve Signal Quality

Environments with large amounts of 5GHz wireless traffic (such as an office), 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.

Advanced Settings → DFS 1 OFF → DFS 2 OFF → DFS 3 OFF → DFS 4 OFF → Status

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)

2. Review Wireless Link Quality

You can view the wireless link quality to determine if there may be interference preventing the signal from completing, or occasional signal loss.

a. Using the IR remote control, press MENU-> Advanced Settings -> Status -> Link Quality

SNR IN	31.1	31.1	26.2	28.1	28.2
SNR OUT	25.2	48.2	19.2	24.0
PIN	8.9	16.9	15.9	13.9	10.9
Freq	5755
Audio BER 0		Packet err 0

b. Several values are now displayed representing the signal quality. See table below for details.

Title Description Details
SNR (IN/. OUT)	Video Quality Values above 20 are ideal.
PIN	Wireless Signal Quality	Values below 55 are ideal
Freq	Wireless Frequency	Displays the wireless Band the connection is on
Audio BER	Audio Bit Error Ratio	Displays Audio Bit Error Ratio
Packet err Packet Loss Displays number of packets dropped

Note: Values outside the "Ideal" threshold may not impact signal quality.
