INTRODUCTION
The Linear 2:8 Distribution Amplier For HDMI is the perfect solution for anyone who
needs to send one or two sources of digital high denition 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 amplier’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 Amplier’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 Amplier
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
rst EDID that it detects. (See note on page 4 for additional information)
The 2:8 Distribution Amplier 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.

CONNECTING THE 2:8 DISTRIBUTION AMPLIFIER FOR HDMI
How to Connect the 2:8 Distribution Amplier For HDMI
Connect the supplied cable from the HDTV HDMI source into the HDMI input port 1. 1
of the 2:8 Distribution Amplier For HDMI.
Connect a second HDTV HDMI source to HDMI input port 2 on the 2:8 Distribution 2.
Amplier For HDMI using a user supplied HDMI cable.
Connect the display(s) (up to eight) to the HDMI output port(s)* of the 2:8 3.
Distribution Amplier For HDMI using user supplied cable(s)
Plug the 24V DC power supply into the 2:8 Distribution Amplier For HDMI.4.
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
Amplier 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 rst
EDID that it detects. The source will output resolutions and timings according the
EDID that is being fed by the 2:8 Distribution Amplier 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 Amplier 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 conguration.

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)
Insert the battery, hold the battery so that you can see the positive side facing up.
3.
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 ash 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 Conicts
In the event that IR commands from other remote controls conict 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 Amplier for HDMI have DIP SWITCHES for conguring 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 Amplier 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 Amplier for HDMI.
NOTE: *DIP SWITCHES 1, 2, and 5 through 8 are not used on the 2:8 Distribution Amplier 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 conicts present in your setup.
Disconnect power from unit before starting. Remove all cabling from unit.
To open the 2:8 Distribution Amplier 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
conicts.
