INTRODUCTION  
The Linear 2:8 Distribution Amplifier For HDMI is the perfect solution for anyone who  
needs to send one or two sources of digital high definition video to multiple displays  
at the same time. It supports HDMI equipment, such as DVD players, satellite set  
top boxes, and HDMI displays. In operation, the digital source is connected to the  
distribution amplifier’s input while eight HDMI outputs are available to be used  
in part or in full. Once the unit is connected and powered, your source can be  
distributed up to eight digital displays at the same time.  
How It Works  
Simply connect your HDMI video source to the 2:8 Distribution Amplifier’s input  
using the supplied HDMI cable. Then connect up to eight HDMI displays to the unit’s  
eight HDMI outputs. Once connected and powered, your source will be seen on all  
eight displays at the same time. When two or more 2:8’s are connected together,  
you can create a larger distribution system.  
OPERATION NOTES  
READ THESE NOTES BEFORE INSTALLING OR  
OPERATING THE 2:8 DISTRIBUTION AMPLIFIER FOR HDMI  
Display information (EDID) is sent from the display connected to HDMI  
Output Port 1 to both sources connected to the 2:8 Distribution Amplifier  
for HDMI. If there is no display connected to HDMI Output Port 1, the  
remaining HDMI Output Ports will be scanned in succession and use the  
first EDID that it detects. (See note on page 4 for additional information)  
The 2:8 Distribution Amplifier for HDMI can only mirror one input video signal at  
a time to all eight display outputs. The user can choose which of the two HDMI  
inputs will be displayed on all eight HDMI outputs.  
HDMI/HDCP compliant  
Compatible with all HDMI and DVI* displays

CONNECTING THE 2:8 DISTRIBUTION AMPLIFIER FOR HDMI  
How to Connect the 2:8 Distribution Amplifier For HDMI  
1. Connect the supplied cable from the HDTV HDMI source into the HDMI input port 1  
of the 2:8 Distribution Amplifier For HDMI.  
2. Connect a second HDTV HDMI source to HDMI input port 2 on the 2:8 Distribution  
Amplifier For HDMI using a user supplied HDMI cable.  
3. Connect the display(s) (up to eight) to the HDMI output port(s)* of the 2:8  
Distribution Amplifier For HDMI using user supplied cable(s)  
4. Plug the 24V DC power supply into the 2:8 Distribution Amplifier For HDMI.  
NOTE: *Display information (EDID) is sent from the display connected to  
HDMI Output Port 1 to both of the sources connected to the 2:8 Distribution  
Amplifier for HDMI. If there is no display connected to HDMI Output Port 1, the  
remaining HDMI Output Ports will be scanned in succession and use the first  
EDID that it detects. The source will output resolutions and timings according the  
EDID that is being fed by the 2:8 Distribution Amplifier for HDMI. Therefore, all of  
the connected displays must be capable of accepting the timings and resolution  
output by the source. It is recommended that the display with the lowest native  
resolution be connected to HDMI output port 1. This is to ensure that a compatible  
video signal will be able to be displayed on all connected monitors.  
OPERATING THE 2:8 DISTRIBUTION AMPLIFIER FOR HDMI  
Switching between the inputs on the 2:8 Distribution Amplifier for HDMI is done using  
either the supplied RMT2-IR remote or the RJ11 to serial interface.  
IR Remote  
Pressing button one on the remote will select the HDMI source that is connected to  
HDMI input port one. Pressing two on the remote will select the HDMI source that is  
connected to HDMI input port two.  
RJ11 To Serial Control Interface  
Please see the diagram on page 7 for the RJ11 serial control interface pin configuration.

RMT2-IR INSTALLATION  
1. Remove battery cover from the back of the RMT2-IR remote.  
2. Verify that dip switches 1 & 2 are in the down (OFF) position. (See page 6)  
3. Insert the battery, hold the battery so that you can see the positive side facing up.  
The side that is not marked must be facing down.  
4. Test the RMT2-IR remote by pressing ONLY one button at a time. The indicator  
light on the remote will flash once each time you press a button.  
WARNING: Do not press multiple buttons simultaneously and do NOT press buttons  
rapidly. These actions will cause the remote to reset and steps 1-4 will have to be  
repeated.  
Note: The RMT2-IR ships with two batteries. One battery is required for operation,  
the second battery is complimentary.  
The optional IR extender allows you to  
relocate your HDMI Switcher and still retain IR  
control. Linear part# IR-EXTENDER

IR CODE CONFIGURATION  
How to Resolve IR Code Conflicts  
In the event that IR commands from other remote controls conflict with the supplied RMT-2IR remote  
control, changing the remote channel will alleviate this issue. The RMT-2IR remote control and the 2:8  
Distribution Amplifier for HDMI have DIP SWITCHES for configuring the remote channel that both units  
use to communicate. These settings must match each other for proper operation. The 2 DIP SWITCH  
bank on the RMT-2IR is located underneath the battery cover. The 8 DIP SWITCH bank for the 2:8  
Distribution Amplifier for HDMI is located inside of the unit. *DIP SWITCH 1 and 2 on the RMT-2IR  
correspond to DIP SWITCH 3 and 4 on the 2:8 Distribution Amplifier for HDMI.  
NOTE: *DIP SWITCHES 1, 2, and 5 through 8 are not used on the 2:8 Distribution Amplifier for HDMI.  
Because the procedure for changing channels requires the main unit to be disassembled, this procedure  
should only be done if there are IR conflicts present in your setup.  
Disconnect power from unit before starting. Remove all cabling from unit.  
To open the 2:8 Distribution Amplifier for HDMI Unit, remove all screws from the sides and underside of the  
unit. Remove the hex nuts above each HDMI connector. Slide the unit apart carefully to expose the internal  
PCB and the 8 DIP SWITCH bank.  
When DIP SWITCH adjustments are complete, carefully slide the unit back together. Being careful not to  
over tighten the hex nuts, screw them back in above each HDMI connector. Screw all of the screws from  
the sides and underside of the unit back into the unit, again being careful not to over tighten the screws.  
Plug all cabling back into its proper location on the unit. Reconnect power to the unit and test for IR  
conflicts.
