1Overview
This document describes how to set up and configure the SightLine OEM boards and camera adapter
boards to receive video from HDMI cameras and HDMI 4K cameras.
See camera configuration tables for the complete list of supported HDMI cameras.
Before connecting with the Panel Plus software, the OEM board should be powered up and connected
through:
-a network switch or directly to the host PC (preferred) or,
-Direct serial connection (for troubleshooting or if a network connection cannot be established).

7Camera Connection and Configuration Notes
See camera configuration tables for the complete list of supported cameras and configuration
settings.
IMPORTANT: Save parameters and reset the board when changing parameters. Cycle system
power when changing resolution.
If the video does not display, try saving and activating the settings again. Check the encoding
settings on the Compress tab and review the network addresses for the destination video.
The 4K HDMI camera attached to the SLA-4000-HDMI is only available as CAM 1.
See EAN-Digital Video Configuration for supported HDMI input frame sizes and frame rates.
The HDMI input boards allow acquisition of HDMI video. Acquisition parameters are set up in the Panel
Plus application. Settings include 720P/1080P resolution and frame step. The SLA-4000-HDMI board
supports 4K resolutions.
At power up, the HDMI board reads the acquisition parameters and generates EDID data
corresponding to the user specified resolution. If the user selects 720P, the EDID data only contains
720P. If the user selects 1080P, the EDID data only contains 1080P. The board programs the HDMI
receiver chip with the corresponding EDID data.
There is no flash memory on the HDMI receiver chip. The EDID data is only programmed and available
after the board has fully booted. Booting can take 20 to 30 seconds from power up.
The HDMI HPD signal is a Hot Plug Detect (HPD). This tells the HDMI source (the camera) that it has
been plugged into an HDMI sink (monitor) and that the source can read EDID data from the sink. Both
HDMI boards have pull-ups to pull this line high.
When the HDMI boards program the EDID data into the HDMI receiver, they automatically pull the
HPD line low when starting to program the EDID, and then release it to high once the EDID data is valid.
This lets the HDMI source (camera) know that the EDID has been programmed and that it should
reconnect to the sink.
The HDMI board receives video with the resolution set up in the Acquisition Settings dialog window of
Panel Plus. It does not require that the EDID data be read, only that correct resolution HDMI video is
sent to the receiver chip.
The HDMI camera may do one of the following:
•If the camera is set in automatic mode and supports the resolution in the EDID data, it can send
video at the requested resolution.
•If the camera is in manual mode, it will remain in 720p or 1080p mode. If this mode does not match
the settings in the Acquisition Settings dialog window in Panel Plus, then no video will display or the
video will be misaligned.
•If the camera does not support the requested resolution in the EDID data, it can output a different
resolution.

EAN-HDMI-Input
© SightLine Applications, Inc. 8
Cameras can support various frame rates at different resolutions. Currently, the EDID data output by
the HDMI board supports the following modes:
•720p30 or 720p60 - camera determines frame rate.
•1080p30 or 1080p60 - camera determines frame rate.
Configuring the resolution on a GoPro camera with the GoPro menus does not configure the HDMI
format.
If the board is power cycled and the HDMI camera is not, there may be issues with video acquisition.
See the Video Acquisition After Power Cycling section.
HDMI cameras output the highest frame rate configurable. When running in 1080p60 mode (or at
60fps), SightLine recommends lowering the frame rate to 30fps using the Frame Step parameter in the
Acquisition Settings dialog window. It is possible that the camera will output 1080p30 or 720p30. In
this case, the Frame Step setting should remain at 0
7.1 Camera and HDMI Board Compatibility
For a list of cameras that have been tested and verified to work with the SLA-3000-HDMI adapter
board see the camera configuration tables. Refer to these tables during camera setup. If a camera is
not listed, contact Support for more information.
7.2 Additional Supported Resolutions
It may be possible to acquire video from HDMI cameras in resolutions other than 720P and 1080P.
While not widely evaluated, the following resolutions are compatible with the 3000-OEM.

7.2.1 VESA Signal Timing
While the current set of acquisition settings cover the main HDMI formats (720P60, 1080P30, 1080P60)
SightLine systems can support other resolutions.
The following examples below were evaluated and have been shown to work on SightLine systems but
are not included in the default acquisition settings.
Also included is an example of using the VESA Signal Timings where these parameters can be deduced.
For other resolutions, the VFP and HFP settings can be determined from the VESA signal timings for
that resolution. For example, searching the web for VESA signal 1280x800 timing returns the settings
shown below.
The SightLine Vertical and Horizontal Front Porch numbers shown in Table 1 correspond to the Back

8Troubleshooting
IMPORTANT: The HDMI source does not need to only be from the camera, it can also be the HDMI
output of a PC if the OEM-board is configured for the image size (resolution) that the PC is
producing.
8.1 Video Not Displaying
There are several issues that can result in video not being
displayed. The camera may not be connected properly, or the
resolution does not match the SightLine hardware Acquisition
Parameters configuration.
In some instances, the SightLine hardware will display a full
green/blue test pattern image as shown. If the SightLine hardware
is configured to receive a higher resolution input than the camera
is sending, then the hardware will display a black No Video Source
message.
Figure 7: No Source Camera Input or
Resolution Mismatch

Recommendations:
•Test the camera by plugging it into an HDMI monitor. If possible, use the monitor settings menus to
find an information screen that shows the current display resolution of the monitor. This will show
the resolution the camera is sending.
•Check the resolution settings on the camera through the camera menu system. The menu
resolution setting will affect the recording resolution, but not always affect the HDMI output
resolution. For example, a GoPro set to record 4K resolution will output a different resolution when
connected to an HDMI monitor that does not support 4K.
•If the camera has a rear screen and is connected to a valid HDMI monitor, the screen will go blank.
Test this with an HDMI monitor and then see what happens when it is connected to the SightLine
hardware. This will tell you if the camera recognizes the SightLine hardware as a valid HDMI device.
•Verify the camera is not in snapshot mode. If the camera is in snapshot mode, cycle through the
modes to where the video camcorder icon displays on the camera display. Normally cameras in
snapshot mode will not output video over HDMI as described in the previous monitor testing
recommendations above.
•Remove the battery from the camera and power the camera externally (through USB) and then try
to connect. Try to delay powering up the camera until the 1500-OEM is fully powered up and see if
that resolves the issue.
It is possible that a power up sequence and timing may be causing the problem.
8.2 Cropped Image
An incomplete image that appears cropped to the top left corner
of the main window of Panel Plus as shown. This issue is common
with Lightdow Action camera.
Recommendation: Unplug the HDMI cable from the 3000-HDMI
adapter board and plug it back in. The image should refill the
screen.
Figure 8: Cropped Image in Panel Plus
8.3 Poor Video Quality
Horizontal lines of color or vertical areas of black on the sides is an
indicator of poor video quality.
Recommendation: From the Panel Plus main menu » Configure »
Acquisition Settings. In the Acquisition Settings dialog adjust the
Vertical and Horizontal Front Porch values to ignore an appropriate
number of lines.
Figure 9: Horizontal Lines of Color
For more information about acquisition fields in Panel Plus see EAN-Digital Video Configuration.

8.4 Video Displays in Gray Scale
From the Panel Plus main menu » Configure » Acquisition Settings. Verify the camera is set to YUV
color, not Gray Scale.
For more information about acquisition fields in Panel Plus see EAN-Digital Video Configuration.
Figure 11: Acquisition Settings - YUV Color
8.5 Video Acquisition After Power Cycling
If the 1500/3000-OEM board is power cycled and the HDMI camera is not power cycled, there may be
issues with video acquisition. This has been an issue with GoPro cameras.
Recommendation:
•Remove and reinstall the battery from the GoPro.
•Remove and reinsert the USB cable supplying power to the camera.
•Power cycle both the 1500 / 3000-OEM and the GoPro at the same time.
In HDMI, the video source (GoPro) communicates with the display device to see what HDMI modes the
display supports. When the power is cycled on the 1500/3000-OEM the GoPro thinks a new display
device has been attached and communicates with it. Sometimes while the 1500/3000-OEM is booting
this confuses the GoPro. The only workaround is to cycle power on the GoPro.
Typically, if a display is turned off, the GoPro will externally power up the HDMI section of the display
to read HDMI formats. This does not work with the 1500/3000-OEM because the HDMI formats are
stored in an externally readable flash memory. The 1500/3000-OEM must boot and program the
supported HDMI formats into memory that can be read by the GoPro or other HDMI camera.
8.6 1500-HDMI Hot Plug Detect Issue
The Hot Plug Detect line does not rise to 5V (instead only going to about 2.6V). While this is within the
HDMI spec (2.4V->5.3V), some cameras like the GoPro only detect the 1500-HDMI board when
outputting the full 5V on the HPD line.

8.7 Missing Driver Chip - 1500-OEM
IMPORTANT: Pre-July 2014 builds without U7 chip installed.
Some pre-production REV C (green PCB) boards shipped prior to July 2014 did not have the U7 driver
chip installed. These boards will not have I2C capability on J4, which prevents HDMI functionality.
Contact Support for more information.
