Setting the Switching Mode  
FAST SWITCHING TECHNOLOGY  
What is Fast Switching Technology?  
Fast Switching Technology (FST) is a Gefen software implementation for HDMI products.  
FST was created to improve the lengthy HDMI authentication process, based on the HDMI  
and HDCP specifications.  
FST provides quicker audio/video source switching and greatly improves the overall audio/  
video system behavior and performance when more than one HDTV display is used in the  
system setup.  
FST allows connecting / disconnecting or turning ON / OFF of HDTV displays without  
having these activities affect other Hi-Def sources routed to any other HDTV display in the  
same system.  
Using Fast Mode  
Use fast switching mode to improve performance when connecting / disconnecting Hi-Def  
sources, and powering ON / OFF HDTV displays.  
1. Disconnect the power supply from the 1:4 Splitter for HDMI 4K x 2K.  
2. Set the FST switch to the Fast position.  
Set to the  
Fast position  
3. Reconnect the power supply to the splitter.  
If the FST switch is moved from the Slow position to the Fast position while the  
splitter is powered, then power-cycle the splitter by disconnecting and reconnecting  
the power supply in order for the change to take effect.

recommended when the source does not support multiple devices.  
1. Disconnect the power supply from the splitter.  
2. Set the FST switch to the Slow position.

LPCM audio.  
1. Disconnect the power supply from the splitter.  
2. Set the EDID switch to the Int position.  
3. Set the Audio switch to the 2ch position.

Operating the 1:4 Splitter for HDMI 4K x 2K  
Setting the EDID Mode  
The 1:4 Splitter for HDMI 4K x 2K features EDID Management. Before the source can  
send video and/or audio to the display (sink), the source reads the EDID (Extended Display  
Identification Data) from the display (sink) devices connected to the splitter. The EDID  
contains information about what type of audio/video data that the source can send to each  
output device. The splitter can use either the downstream EDID (from the display/sink) or  
the built-in internal EDID.  
Using the Internal EDID  
Use this EDID mode if problems are encountered when using the external EDID.  
The built-in internal EDID provides the source device with a “generic” EDID which can be  
used by all display (sink) devices. The use of the internal EDID also provides control  
of the audio output format. See Setting the Audio Channel Mode for more information.  
1. Disconnect the power supply from the splitter.  
2. Set the EDID switch to the Int position.  
Set to the Int  
position  
3. Reconnect the power supply.  
If the EDID switch is moved from the Ext position to the Int position while the splitter  
is powered, then power-cycle the splitter by disconnecting and reconnecting the power  
supply in order for the change to take effect.  
See Table 2.1 on the next page for specifications on the internal EDID.

Using the External EDID  
When set to Ext mode, the splitter will fetch the EDID data of each display (or other sink  
device) that is connected to the splitter. Once this information is gathered, the splitter  
“builds” an EDID based on the highest video resolution and most superior audio format  
that is supported by both sink devices. This EDID is then transmitted to the source device.  
1. Disconnect the power supply from the splitter.  
2. Set the EDID switch to the Int position.  
Set to the Ext  
position  
3. Reconnect the power supply.  
If the EDID switch is moved from the Ext position to the Int position while the splitter is  
powered, then power-cycle the splitter by disconnecting and reconnecting the power  
supply in order for the change to take effect.

Appendix  
Wall Mounting Instructions  
The 1:4 Splitter for HDMI 4K x 2K should be mounted vertically in a wall or cabinet with  
wood/drywall screws as shown in the diagram above. There should be an inch or two of  
clearance between the edges of the unit and any walls or vertical surfaces to allow for  
enough clearance for insertion and retraction of cables at the HDMI connectors.  
For installation on a drywall surface, use a #6 drywall screw. It is recommended when  
installing on a drywall surface that studs be used to secure the splitter should undue stress  
be applied when connecting and disconnecting HDMI cables.
