Infrared Control (IR)

The area on the front panel labeled 

IR or IR Extender 

is the IR 

Transmitter (IR-TX) port. 

Using the Ultra-IR Adapter Kit (optional) enables the control of the source 

device from the location of the display. Plug the HDMI cable into the IR 

Adapter at the display end. Next plug the IR Adapter’s HDMI connector 

into the display. The IR Adapter has a port that accepts an optional IR 

Receiver (IR-RX). When the IR-RX receives an IR signal from the source 

devices remote control, it uses the HDMI cable’s CEC line to send the 

signal to the splitter. Plug the optional IR-TX into the IR port on the front 

panel of the splitter. Point the end of the IR-TX at the source device. 

The signal is transmitted through the IR-TX sending the IR signal to the 

source device.
Note: As the Ultra IR-Adapter uses the CEC channel of the HDMI cable, 

the CEC function cannot be used when using this device. Turn off CEC or 

HDMI Link functionality in the source devices and displays. 
The illustration below shows the optional Ultra-IR Adapter Kit controlling 

the source device on a 1x4 splitter. The 1x8 splitter is setup in a similiar 

manner. Note: Due to specific pin requirements, only use Accell Ultra-IR 

transmitters or receivers.

Troubleshooting

Q. One of the display does not show a picture or output audio.

A. Check the displays input setting to ensure it is set to receive a signal 

from the connected HDMI port.
Q. One or more of the connected displays will not display a picture while 

one or more of the displays do display a picture:  

A1. Press the 

RESET

 button on the front of the splitter to reset it. 

Alternatively turn off the power to the splitter, source and displays. Wait 

60 seconds. Turn the source on. Turn the displays on.Turn the splitter on.

A2. The HDMI cables on the non-functonal display/s cannot support 

their long length.  Use only high-quality High Speed HDMI cables. Keep 

the cable length as short as possible. Test by locating the non-working 

display close to the splitter. Use a short HDMI cable to connect the 

splitter to the TV. A working TV using a short HDMI cable indicates an 

issue with the HDMI cable.
Q. Get the message “This protocol is not supported” or other error 

message. 

A. See answer A1 above and repeat the steps outlined.
Q. The splitter is not down sampling the video and some of the TV’s are 

not displaying a picture.

A1. Go into the TV’s setup and configure the resolution to match all the 

connected TV’s. The TV’s should share the same resolution. 

A2. In the source devices menu options set the source device to output a 

resolution that matches all the connected displays.
Q. My TV’s resolution are not optimized.

A. The splitter will query the displays and provide the highest common 

video resolution amongst them. Example: Using a 1080p source, if 3 

of the displays support a maximum resolution of 1080p and 1 display 

supports a maximim resolution of 720p, all 4 display will operate at a 

resolution of 720p.  If the 720p TV in the example is then turned off, the 

other 3 displays can then operate in 1080p resolution. Press the 

RESET

 

button on the front panel of the splitter to refresh the configuration. The 

three 1080p TV’s will refresh (flicker) then each will display a 1080p 

resolution picture.
