WHD-PRO330-K Overview and Use Cases

What Is the WHD-PRO330-K?

The OREI WHD-PRO330-K is a 1080p wireless HDMI sender and receiver kit that sends HDMI video and audio wirelessly from one HDMI source to one HDMI display.

The kit includes a Transmitter and Receiver. The HDMI source connects to the Transmitter, the display connects to the Receiver, and the HDMI signal is sent wirelessly between both units.

The WHD-PRO330-K supports wireless HDMI transmission up to 1080p, 3D HDTV signals over HDMI, HDCP compliance, HDMI pass-through output on the Transmitter for local display viewing, IR extender function, low power consumption, and wireless transmission up to 100m / 330ft line of sight. The manual lists latency as less than 300ms.

The WHD-PRO330-K is useful for home theater, room-to-room HDMI transmission, meeting rooms, game rooms, projector setups, and situations where running a long HDMI cable is not practical.

IMPORTANT — WHD-PRO330-K Supports 1080p, Not 4K

The WHD-PRO330-K supports wireless HDMI transmission up to 1080p.

It does not support 4K, 4K@60Hz, 4K@120Hz, or 8K.

For 4K wireless HDMI, use a wireless extender model that specifically supports 4K.

IMPORTANT — Wireless Distance Is up to 100m / 330ft Line of Sight

The WHD-PRO330-K supports wireless transmission up to 100m / 330ft line of sight.

Line of sight means the best performance is achieved when there is a clear path between the Transmitter and Receiver.

Walls, furniture, AV racks, metal objects, Wi-Fi routers, microwaves, air conditioners, and other wireless interference can reduce the working distance.

The manual also notes that the optimum indoor range is less than 330ft.

IMPORTANT — This Is Not Zero-Latency

The WHD-PRO330-K has wireless transmission latency.

The manual lists latency as less than 300ms.

This is acceptable for many home theater, meeting room, presentation, and general video applications.

It is not ideal for fast gaming, live performance monitoring, or applications that require instant response.

IMPORTANT — HDMI Loop Out Is on the Transmitter

The Transmitter includes an HDMI OUT port.

This HDMI OUT port allows a local display to be connected near the HDMI source.

Example setup:

This is useful when the source needs to be viewed locally and wirelessly sent to another display.

IMPORTANT — IR Extender Function Is Supported

The WHD-PRO330-K supports IR extension.

This allows the user near the Receiver/display side to control the source device located near the Transmitter.

Typical setup:

1. Connect the IR emitter probe to the Transmitter
2. Place the IR emitter in front of the source device’s IR receiver
3. Connect the IR receiver probe to the Receiver
4. Point the remote control at the IR receiver probe near the display 
    
   The IR extender function supports 30kHz to 60kHz IR remote control systems.

IMPORTANT — Both Transmitter and Receiver Need Power

The WHD-PRO330-K package includes two DC 5V/1A Micro USB power adapters.

This means both the Transmitter and Receiver need their own power connection.

Use the included power adapters whenever possible.

If using your own adapter, the manual says the output connector must be Micro USB and the power output must be DC 5V/1A.

IMPORTANT — Pairing May Be Needed

If there is no video signal, the Transmitter and Receiver may need to complete pairing.

The manual says to:

1. Press the MODE key once on the Receiver.
2. Wait for the pairing message on the screen.
3. Press the MODE key once on the Transmitter.
4. Wait for the connection to establish.

Ports and Panel Layout

Step-by-Step Setup

1. Connect the HDMI source device to HDMI IN on the Transmitter. 
   Examples include a satellite receiver, cable box, Blu-ray player, PS4, PS3, Xbox, streaming device, or media player.
2. Optional: Connect a local display to HDMI OUT on the Transmitter.
3. Connect HDMI OUT on the Receiver to the remote display. 
   Examples include a TV, HDTV, monitor, or projector.
4. Connect the IR emitter probe to the Transmitter if IR control is needed.
5. Place the IR emitter probe in front of the source device’s IR receiver.
6. Connect the IR receiver probe to the Receiver.
7. Place the IR receiver probe where the remote control can point at it.
8. Connect one DC 5V/1A power adapter to the Transmitter.
9. Connect the second DC 5V/1A power adapter to the Receiver.
10. Power on the HDMI source and display.
11. If no video appears, press MODE once on the Receiver, then press MODE once on the Transmitter to pair.

Wireless Signal Requirement — Critical

For best performance, keep the Transmitter and Receiver within line of sight.

Wireless performance may be affected by:

1. Walls
2. Cabinets
3. Metal objects
4. AV racks
5. Wi-Fi routers
6. Microwaves
7. Air conditioners
8. Other wireless devices
9. Long distance between units 
    
   If the video is unstable, move the Transmitter and Receiver closer together, reduce obstacles, and change the direction of the units for better reception.

HDMI Cable Requirement — Critical

Use good-quality HDMI cables between:

1. Source device and Transmitter HDMI IN
2. Transmitter HDMI OUT and local display, if used
3. Receiver HDMI OUT and remote display 
    
   The manual recommends High Speed HDMI cables. 
    
   Poor HDMI cables may cause:
4. No picture
5. No sound
6. Intermittent signal
7. HDCP handshake issues
8. 3D signal problems
9. Unstable video 
    
   For troubleshooting, test the source directly with the display first.

Understanding the Transmitter

The Transmitter is installed near the HDMI source.

It has:

1. HDMI IN for the source
2. HDMI OUT for local display pass-through
3. IR OUT for the IR emitter probe
4. Micro USB power input
5. MODE button for pairing 
    
   The Transmitter sends the HDMI signal wirelessly to the Receiver.

Understanding the Receiver

The Receiver is installed near the remote display.

It has:

1. HDMI OUT to the display
2. IR IN for the IR receiver probe
3. Micro USB power input
4. MODE button for pairing 
    
   The Receiver receives the wireless HDMI signal and outputs it to the display.

Understanding IR Extension

The IR extension function lets the source remote control work from the Receiver side.

Example:

The remote control should be used between 1ft and 17ft from the IR receiver probe, with a working angle of about ±15 degrees.

Some remotes may require pressing and holding the button for about one second.

Understanding Pairing Mode

Use pairing mode when the Receiver does not show video.

Pairing steps:

After pairing is complete, the display should show the wireless video signal.

Understanding LED Indicators

Use these indicators when troubleshooting no video or connection issues.
