4. Installation
Connection Block Diagram
Perform the following steps to install the SP-HD-4C.
1. Make sure your HDMI Sources and Displays that you are intending to connect are powered
off and disconnected from power sources.
2. Using Hi-speed HDMI cables, connect each display to the Outputs ports of the splitter.
3. Similarly connect the video source to the Input port of the splitter.
4. Power the splitter using the supplied DC power supply.
5. Power on all the displays followed by source.
6. Make sure the LED indicators for the HDMI Input and corresponding HDMI Outputs are
illuminated.
7. Verify audio and video at each output display.
5. Smart EDID Management
When the unit powers up or when it first detects that a video source is connected the device, it
creates an EDID for the source based on the first display found scanned from #1 to #4, in order.
If you have a mix of 4K and 1080p displays, make sure to connect the 4K display to output #1.
That way the EDID generated for the source will have 4K native causing the source to output a
4K image. Then for the displays that do not support 4K, set the max resolution Dip Switch on
the front panel to 1080p (see next section).
If no displays are connected, the splitter uses an internal "default" Hall Research EDID so the
HDMI source will always send a signal. This internal EDID will be used until an external
display is connected to one of the output ports.
Only use the regulated 12 vDC supply (center
positive) supplied with the unit. Never substitute any
other power supply as this can destroy the unit.
