3.2.2 CONNECTIONS ON THE SINGLE-PORT MULTI DVI
3. Setup and Installation
The AC1100A, AC1101A, AC1112A units support DVI video over CAT5 cable .
3.1 Cabling Considerations
Figure 3-1 shows the video only Multi DVI System Transmitter connections, and Figure
3-2 shows the receiver connections.
• We recommend mounting and connecting all cabling to the Multi DVI System
components before applying power. Please note recommended power sequence below.
3.2 Making the Connections
3.2.1 Connections and Setup in General
This section contains figures showing connections with the specific Multi DVI System
models. In general, however, the connection and setup procedure at both transmitter
and receiver ends is as follows:
At the transmitter end:
1. Connect the source video to the Multi DVI System transmitter video input port, which
is a DVI connector labeled DVI IN.
2. If desired, attach a local monitor via the local monitor port to DVI OUT.
3. Connect the CAT5 cable to the transmitter.
4. Do not apply power to the transmitter at this time.
At the receiver end:
Figure 3-1. Transmitter connections on the AC1100A.
1. Connect the DVI OUT connector to the display unit,.
2. Make sure that the Cat5 cable connection from the transmitter or receiver are secure.
3. Apply power to the display, then to the receiver.
4. Next, the transmitter should be powered on and finally the video source signal.
Reference Appendix B for Link status and LED indicator explanations.
If there are any problems at either end, see Chapter 4.

CHAPTER 3: Setup and Installation
3.2.3 CONNECTIONS ON THE DUAL DAISYCHAINABLE RECEIVER
MULTI DVI SYSTEM.
4. Troubleshooting
The dual daisychainable receiver is used when the same signal is distributed to
multiple display devices on a single cable in a daisychain or loop-through
fashion. CAT5 Cable lengths must not exceed 600 ft between units.
4.1. Common Problems
In most cases, nearly every issue with the Multi DVI System can be resolved by
checking the Fiber optic or CAT5 cable and making sure that it’s properly
terminated and in the case of CAT5 cable, pinned to the TIA/EIA 568B wiring
specification. However, there may be other problems that cause the system to not
perform as it’s designed. Below are solutions to the most common installation
errors.
Setup and cabling are the same as the single-port receiver, but the dual
daisychainable model has an additional RJ-45 connector for linking to another
dual daisychainable receiver or single-port receiver.
Figure 3-3 shows how connections are made on the dual daisychainable receiver.
Problem:
Solution:
No video signal at the transmitter local port or at the receiver.
• Check that both units are powered.
• Make sure the cable is terminated correctly.
• Is the display device powered on and functioning?
• Power on units in sequence (display, receiver, transmitter, video
source).
• Display may not be correctly identified by source device. See
Appendix E for DDC communication issues.
Problem:
Solution:
Video signal is poor.
• See Appendix C for changing compression mode.
• Check all cable connections.
• The video signal’s refresh rate may be set too high. Reset to a
lower refresh rate in your monitor-configuration menu.
• In 1080P mode, the PC graphics card needs to be set to
reduced clock rate mode. Contact the graphics card
manufacturer.

APPENDIX A:Cabling Pinouts
MULTI DVI SYSTEM.
Appendix B. Status LED’s
The Multi DVI System feature “status-at-a-glance” LED’s to ensure the units are functioning
properly and to isolate problems with input signals, units, and/or cabling thus saving time during
installation and troubleshooting. Reference the following tables for information on theses
indicators. The UTP connector also contains LED indicators on either side to provide visual cues
on connection and traffic status.

APPENDIX C:Compression Mode
MULTI DVI SYSTEM.
APPENDIX D. DDC Modes
Appendix C. Compression Mode
The Multi DVI System features the ability to send DDC display identifiers to the
video source in order to determine display capabilities. The DDC is a data
communication channel used in plug and play devices to accurately report a
displays capabilities and identify the manufacturer. If this data is not available,
the video source may revert to a low resolution or not display at all.
The Multi DVI System features two video compression modes to enable high resoluiotn
video extension over long distances. Compression modes may be changed with a
simple jumper setting accessible through the front cover. All units must be set to the
same compression mode for proper operation.
The Multi DVI features the ability to report a Universal Display (MRI Magic
Display) that supports most popular VESA standards in standard or
widescreen formats as well as the ability to clone an actual displays DDC
information that is attached to either the local DVI output of the transmitter or a
receivers DVI output.
The two modes are:
Pixel Compression mode. Suitable for static non motion content. DEFAULT
Jumper J10 IN
The various modes are detailed below:
Color Compression mode. Suitable for moving content such as DVD movies.
Jumper J10 OUT
Mode 1: Universal Display (MRI Magic Display) (DEFAULT)
This mode reports a generic display supporting popular screen
formats and is suitable for most if not all display types.
To change the compression mode, remove the compression mode jumper access
cover on the front of the Multi DVI unit and remove or install a jumper on J10
underneath
Mode 2: Clone DDC from DVI Output of transmitter
This mode copies the DDC from a display attached to the local output
of the transmitter.
Mode 3: Clone DDC from receiver (first one if using daisychain options)
This mode copies the DDC data from a display attached to the
receiver (first receiver if a daisychain mode is in use).
To change modes requires internal jumpers to be changed. See Figure E-1 for
jumper locations (settings are stored in non-volatile RAM and are not lost when
power is removed):
Mode 1: To restore, install jumper J20 while transmitter is power on. No other
cable connections need to made.
Mode 2: To clone DDC from a display connected to the local DVI output of the
transmitter, Install a jumper on J9 and J20 while transmitter is
powered off, then connect the display to the transmitter and power it
on. Remove J20 while transmitter is powered on and leave J9 in. The
video source does not need to be connected.
Mode 3: To clone DDC from a display connected to the DVI output of the
receiver, remove jumper on J9 , ensure J20 is in while transmitter is
powered off, then connect the display to the receiver and the receiver
to the transmitter and power everything on. Remove J20 while
transmitter is powered on and leave J9 off. The video source does
not need to be connected.

Appendix E. Rackmounting Units
The Rackmount Kits include brackets for mounting a transmitter, receiver, or a dual
daisychainable receivers in a 19 rack. Figure F-1 shows the 2-Unit Rackmount
Bracket (AC1011), which holds three units in a 19" x 1U rack.
Not shown are brackets for 6 units . The 6-Unit Transmitter/Receiver Bracket
(AC1012) is like the AC1011 but occupies 2U of space instead of 1U in a 19" rack,
stacking 3 units atop 3 units.
