3. Setting-up a Link
3.1 Enabling communication to the wireless module
Seagull boards can work with Canary, Pashosh and Shaldag application boards.
Canary and Pashosh use I2C protocol with the Seagull board, while Shaldag uses
SPI protocol. The Seagull boards contain Dip Switch to select I2C/SPI
communication. In case using Pashosh/Canary, dip switch 1 should be set to ‘On’ (as
the figure below). In case using Shaldag dip switch should be off.
Figure 3 – SW6
3.2 Basic Link Set-Up
To create a link, follow the below procedure:
Connect the Tx module to a video source using an HDMI cable. Use HDMI 0
port by default (this is Shaldag based system default)
Connect the Rx module to a display (monitor/TV/projector) using an HDMI
cable.
Connect the power supplies to both Tx and Rx modules. Ensure that the
power switches are off.
Power on the Tx using the power switch and wait for the status LEDs (L2) to
turn on. They should be red if no source is connected and turn green if a legal
source is connected and the video resolution is identified. Refer to section
5.5 for more information.
In case the source is off, turn it on and make sure it is set to output a legal
resolution (refer to section 4.1). The status LEDs (L2) on the Tx should turn to
green once the source was recognized and the transmission is set and (refer
to section 5.5).
Make sure your display is on and set to the right input source.
Power on the Rx using the power switch. L1 yellow LEDs should turn on once
association is completed and the link is connected (refer to section 5.5). Link
establishment process may take 10-15 seconds.
Once link is established, RX L2 LEDs should turn green, and there should be
audio and video reception on the display.
In case the display has only a DVI port and the Rx can be connected to a
display via an HDMI to DVI cable. Refer to section 5.7 for explanation on
setting DVI mode.

4. System Configuration
4.1 Supported resolutions
The Sparrow system currently supports video formats up to and including:
720p 60fps
1080i 60fps
1080p 24fps/30fps
1080p 60fps (Shaldag system)
The system is configured to automatically recognize the resolution, and adjust
accordingly. Switching sources and resolutions once the link is set is legal, and the
system should adjust automatically, although this may result in a few frames of blank
video and may take a few seconds. The system is also capable of recognizing the
color space (RGB/YCbCr) and adjusting accordingly.
4.2 HDMI
To ensure full support and optimal performance, the HDMI (or DVI) source and
display connected to the WHDI Reference Design system should support EDID and
HDCP, and should provide the necessary 5V DC voltage as specified by the HDMI
requirements.
WHDI Reference Design Setup Guide Dev Kit-UG1_Rev 1.0.27
5. User Interface
Figure 4 – User Interface General View
5.1 Video Input selection
Toggle between video input ports – HDMI 0, HDMI 1, VGA, Component
Button
o On Tx with Pashosh wireless board – short press on B1
o On Tx with Shaldag – no selection can be done via the keypad. Default
port is HDMI 0
LEDs: according to section ‘Video-in status Tx & Rx’ below
Note: In some older Shaldag system, short press on B1 button will reverse the output
pixel clock polarity, and only HDMI 1 is available. This is a temporary solution.
5.2 Video input status Tx & Rx
o No video input (Rx & Tx) – L2 red
o Unsupported video input (Rx & Tx) – L2 blinking red (future implementation)
o Video input exists and legal (Tx, and if link exist then Rx as well) – L2 green
5.3 Registration (both Tx and Rx)
Registration is the process where the Tx and Rx exchange a public key and generate
a unique master key that is stored in non volatile memory.
Registration needs to be done only once for each pair of Rx and Tx. After successful
registration the registered Tx and Rx can create link only with each other and cannot
link with other devices.
Note: A system sent from Amimon will already be registered
o Button: To start the registration process, apply a long press (3 seconds) on B2 of
both Tx and Rx.
o LEDs: Upon successful registration a link will be established and L1 LEDs should
turn solid yellow. L2 will be solid red in case there is no video input or solid green
in case of video input.
5.4 Association (Tx & Rx)
Association is the link set-up phase between two registered devices. The Tx and Rx
create session keys using the master key that was created during registration.
o Button: Association starts automatically upon power-up. If for some reason
manual association is required (mostly for debug purposes), apply a long press
Confidential Under NDA
Internal document. Information subject to change 13 Page
WHDI Reference Design Setup Guide Dev Kit-UG1_Rev 1.0.27
on the B1 button on one of the boards to start association. Applying a long press
on B1 when link is already in progress will disassociate. After disassociation the
system will automatically try to re-associate.
o LEDs: L1 is solid yellow once link is established.

5.5 RF frequencies table selection
It is possible to configure the system to work with 3 different frequency pre-defined
tables, which are stored by default in the wireless board. The tables contain the
certified frequencies per the following regions: MIC, ETSI, FCC
To select a frequency table, follow the procedure below:
Press on the required buttons according to the table below and only then power up
the Seagull board. Wait until L2 LEDs are blinking.
1. Release the pressed buttons.
2. The Application will continue the boot process and will start working with the
desired frequency table
3. The Application keeps the table ID on its local EEPROM, so next boot same
frequency table will be used
Press one of the following buttons combinations before powering on the board
Buttons
combinations

o Button: a short press on B3 will disable TPC and set fixed output power setting.
additional press will increment the power according to the following power Steps:
11, 14, 17, 20 & 8 dBm
o LEDs: LEDs L6, L5 & L3 indicate the power level of the Tx in binary mode. L6
marks LSB and L3 marks MSB. Upon power change the relevant LEDs will blink
for a few seconds
5.7 Manual frequency selection
By default, the transmission RF frequency is decided automatically by the system’s
Automatic Frequency Selection (AFS) mechanism, out of the pre-defined frequency
table. It is possible to disable AFS and select the frequency manually.
Note: Currently this feature is enabled only with Pashosh wireless boards.
o Button: a short press on B2 will disable AFS and set fixed transmission
frequency. Each press will switch to the next frequency in the pre-defined
frequency table.
o LEDs: LEDs L6, L5 & L3 indicate the selected frequency in binary mode. L6
marks LSB and L3 marks MSB. Upon frequency change the relevant LEDs will
blink for a few seconds
5.8 Broadcast mode (both Tx and Rx)
This mode is used to set the system to broadcast mode. In this mode the Tx sends
the video unencrypted so any Rx that is set to broadcast mode can receive the video
without going through registration. Please note that even if HDCP is enabled in the
system – it will not work in broadcast mode. Setting broadcast mode is registered in
an EEPROM in the system and will remain even if powered down. In order to return
to unicast mode, repeat the process.
o Button: Upon power up keep pressing all 3 buttons until L2 is blinking in red (do
it both for Tx and Rx). Repeat (upon power-up) to return to unicast.
o LEDs: L1 will blink slowly when in broadcast mode.
5.9 Link exists (both Tx and Rx)
After Link setup the Tx should transmits video frames and the Rx should receives
them. The following is the link indications:
o MAC does not response – L1 blink fast.
o MAC response but no LINK – L1 off.
o Link is active unicast – L1 solid.
o Link is active broadcast – L1 blink slowly.
5.10 Communication error (both Tx and Rx)
If there is a system error (such as bad I2C/SPI communication between the MAC and
the application), there will be a system error indication.
o LEDs: L1 fast-blinking yellow

5.11 DVI mode (Rx Only)
In case the display has only a DVI port and the Rx is connected to a display via an
HDMI to DVI cable, you should set the Rx in DVI mode which removes the audio
from the link. This mode can also be used to mute an HDMI link. o Button: A short press on B3 sets the Rx in DVI mode (default mode is HDMI). An
additional press returns the Rx to HDMI mode.

6. Basic Troubleshooting
Before proceeding to the common troubleshooting procedures below make sure that
Tx, Rx, source and display are powered, connected and on. Then proceed:
Issue:
No video: Check the status of the Link LEDs:
LEDs off Make sure the power is connected and devices are on
Tx L2 red Make sure the source is on, connected to the HDMI port and
outputting a legal resolution. Try to switch the input to the other
HDMI port. Connecting a valid video to the right HDMI port should
switch the LEDs from green to red.
Rx L2 red Make sure the Tx is transmitting (L2 on Tx is green), and check if
the devices were pre-registered.
Make sure that if L2 is green on the Tx, it turns red when pulling
out the HDMI cable. If not – the input selected is probably
component or VGA. Switch to HDMI by applying a short presses
on B1 until HDMI port is selected.
Tx or Rx L1
(Yellow LEDs)
blinking fast
Hardware issue: check connection between wireless and
interface boards. Check the correct state of dip switch 1
Rx L2 green, but
no image on
screen
Make sure the display is connected, on and set on the right
channel/source
Tx and/or Rx L1
blinking slow
One or more of the link sides are in broadcast mode. If
only one of them is in broadcast mode a link will not be
established. Either set both to broadcast mode or both to
unicast mode
If both are in broadcast mode intentionally, make sure
your source in not an HDCP source. Broadcast mode
does not support HDCP content.
Bad Picture Make sure the HDMI cables used are intact and that you
get a good picture by connecting the source directly to the
display by an HDMI cable (bypassing the WHDI link).
Make sure nothing is touching or blocking the antennas
Try restarting the link
‘Dot noise’
around color
transitions
In Shaldag only – Randomly the system may power on
with reversed polarity of the pixel clock output. Apply a
short press to B1 on the Seagull Tx keypad board
Bad Audio/No
Audio
Make sure the volume on the receiver is on
Make sure that the source is outputting legal audio
formats (the system currently does not support HD audio)
Make sure you are not in DVI mode and you are not using
DVI cables anywhere in the link
If there are mutes during the link, try restarting the link
Make sure there are no wireless phones in the area that
use the 5.8 GHz band, as some of the phones on the
market use sub-standard transmission schemes.
Other Issues /
Unresolved
Issues
If any other issue occurs of if the above issues persist, try
powering off both Rx and Tx and repeating the link set-up
process
