CAT5 MULTI VIDEO SYSTEM.
2. Introduction
2.1 Overview
The CAT5 Multi Video System extends VGA or Component video signals as well as
stereo audio and RS232 signals over ordinary Category 5 cable. All models support
RGBHV, RGB, VGA, and component video, and they use a transmitter-to-receiver
setup. They can be used as video splitters as well as video extenders.
This manual covers CAT5 Multi Video System Transmitter/Receivers (AC1060 -
AC1062A, AC1065A-AC1066A).
These models enable you to broadcast line-level mono audio and RS232 serial, along
with video from your computer, to as many as 100 computer monitors up to 500 feet
(152 m) away over CAT5.
CAT5 Multi Video System receivers are available with single or dual daisychainable
connections. The dual daisychainable receiver is used when the same signal is
distributed to multiple display devices across a single CAT5 cable in a daisychain or
loop-through fashion. Setup and cabling are the same as the single-port receiver.
All models support refresh rates/resolutions up to 2048 x 1536 @ 75 Hz at up to
500 feet (152 m).
WARNING
This equipment is not intended for, nor does it support, distribution
through an Ethernet network. Do not connect these devices to any sort
of networking or telecommunications equipment!
2.2 Package Contents
You should have received the following when ordering a CAT5 Multi Video System
receiver:
• The transmitter or receiver.
• External power supply (100–250 VAC, 50–60 Hz, autosensing) with cord.
• This manual.

2.3 Equipment You May Also Need
• Rackmount Brackets:
For or single-port/dual daisychainable units:
AC1009 for 4 transmitter units; AC1010 for 8 transmitter units;
AC1011 for 3 receiver units; AC1012 for 6 receiver units;
• Audio cable with RCA jacks.
• Video cable with HD15 connectors.
• Serial cable with DB9 connectors.
• CAT5 cable.
• For the single-port audio models, an audio splitter.
2.4 Compatible Cabling
CAT5 cabling for the CAT5 Multi Video System must be pinned to the TIA-EIA
T568B wiring specification. We also highly recommend that all CAT5 cables
be pre-terminated and tested. Cables terminated on-site or in an existing
infrastructure should be tested before use to ensure compliance with the TIA-EIA
T568B specification. Using incorrectly terminated CAT5 cables can damage the
CAT5 Multi Video System.
CHAPTER 2: Introduction

CAT5 MULTI VIDEO SYSTEM.
3. Setup and Installation
3.1 Data Mode Configuration
RS 232 Serial signals are fixed at 9600 baud. Three wire serial protocol is used (Tx, Rx,
GND). There are no changeable configuration settings.
3.2 Cabling Considerations
• We recommend mounting and connecting all cabling to the CAT5 Multi Video
System components before applying power.
• Makes sure that the CAT5 cable you intend to use has been tested to comply
with the TIA/EIA 568B wiring specification.
3.3 Making the Connections
3.3.1 Connections and Setup in General
This section contains figures showing connections with the specific CAT5 Multi
Video 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 CAT5 Multi Video System transmitter video
input port, which is an HD15 connector labeled SOURCE IN.
2. If desired, attach a local monitor via the local monitor port to LOCAL OUT.
NOTE
The single-port units with audio have a single audio input. So, for audio
capabilities on the attached monitor, you’ll need an audio splitter.
3. Make your audio or serial connections.
Connect the audio input to the AUDIO connector Pins 1 (Left Audio +) , 2 (ground), 3
(Right Audio +)
Connect the serial input to the RS-232 (DB9 female) port.
4. Connect the CAT5 cable to the transmitter.
5. Apply power on the transmitter. The LED should light and, if there’s a local
monitor attached, a video image should appear on the monitor’s screen.
At the receiver end:
1. Connect the SOURCE OUT HD15 connector to the display unit, and attach
any audio or serial connections.
2. Make sure that the CAT5 cable connection(s) from the transmitter are secure.
3. Apply power. The LED should light and video should appear on the display
(make sure display is powered ON).
4. For video clarity, adjust the EQ compensation knob, which optimizes
the image for the length of CAT5 cable used. Counter clockwise is zero feet of cable
and clockwise is 500 ft of cable. Turn knob slowly to ensure display has time to sync
up.
6

5. If necessary, adjust one or two (never all three) of the skew compensation switches
to add a 10ns delay for that color. This may be necessary for Cat6 cables or cat5/5e
cables in the 400 to 500 ft range.
If there are any problems at either end, see Chapter 4.
3.3.2 CONNECTIONS ON THE SINGLE-PORT VGA/AUDIO/SERIAL
The single-port units support video, serial and audio signals over CAT5 cable.
The audio signal is line-level audio, and powered speakers are required. Note that
there’s a single connection for audio input. If you use a local station, you’ll need an
audio splitter for that jack. (For more information, call Technical Support).
The serial signal is 3 wire RS232 (Tx, Rx, Gnd).
You can also use the transmitters and receivers to make video-only connections without
audio or serial.
Figure 3-1 shows the Single-Port CAT5 Multi Video System Transmitter connections,
and Figure 3-2 shows the receiver connections.
The Multi Video receiver unit AC1065A is used for component video. A video adapter
cable is required to connect RCA video inputs into the HD15 connector.

3.3.3 CONNECTIONS ON THE DUAL DAISYCHAINABLE VGA/AUDIO/SERIAL
RECEIVER
The dual daisychainable receiver is used when the same signal is distributed to
multiple display devices on a single CAT5 cable in a daisychain or loop-through
fashion.
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 3-7 shows how connections are made on the dual daisychainable receiver. Note
that serial is one way simplex.
The Multi Video receiver unit AC1066A is used for component video. A video adapter
cable is required to connect RCA video inputs into the HD15 connector.

4. Troubleshooting
4.1. Common Problems
In most cases, nearly every issue with the CAT5 Multi Video System can be
resolved by checking the CAT5 termination and making sure that it’s 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.
Problem: No video signal at the transmitter local port or at the receiver.
Solution: • Check that both units are powered.
• Make sure the CAT5 cable is terminated correctly per the
TIA/EIA 568B wiring specification.
• Is the display device powered on and functioning?
In some cases, the video termination may be mismatched. The
transmitters and receivers ship with 75-ohm termination as the
default. To disable termination, see Appendix B.
Problem: Video signal is poor.
Solution: • Have all receiver settings been finished (see sections 3.3).
• 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.
• There may be a delay skew issue. Call Technical Support.
Problem: Audio is poor.
Solution: • Powered speakers are required. Make sure speaker power is
ON.
• Check input source levels from the source device. Make sure
the audio source is not overdriven or underdriven.
Problem: Serial communication doesn’t work correctly.
Solution: • Are the serial devices connected properly? Are the serial
parameters correct for source/destination devices?
• Are the serial cables terminated correctly? If a null-modem
cable is used, it must be placed at the receiver end.
• When using daisy chain receivers, the serial signal is
a unidirectionally broadcast mode only. In this mode, all other
CAT5 Multi Video System devices must be the simplex serial
type. For assistance, contact Technical Support.
• The last device in a daisychain configuration must
be a standard receiver unit with a terminated serial board.
10

CHAPTER 4: Troubleshooting
Problem: “Green shift” or “green washout” on multimedia signals.
Solution: Please contact Technical Support.
The standard video/serial model is designed to function with DC
coupled signals in which the black level is referenced to 0 volts.
Nearly all VGA cards function this way.
Some media servers, however, provide AC coupled signals and
can cause a green color shift in the video. This is a result of the
sync clamping on the red and blue channels of the video/serial
model.
For five-component (RGB/H&V) AC coupled video, the
AC1060A single port transmitter has optional DC restoration
circuitry that is easily enabled via a dipswitch setting (see
Appendix C.
4.2 Calling Black Box

Appendix B. Setting Sync Signal
Output Termination
In some cases, it may be necessary to disable the 75-ohm termination of the video
outputs on the CAT5 Multi Video System units. This can be done by opening the
case of each unit and installing jumpers on the circuit board. The settings
disable/enable the 75-ohm termination on individual units. For instance, changing
a transmitter termination affects the local monitor port only; it doesn’t affect the
receivers. Conversely, changing a receiver affects the output port of the receiver,
not the transmitter. The following diagrams show the jumper locations for each
type of assembly reference the transmitter manual for transmitter settings.

APPENDIX B:Sync Termination
Appendix C. DC Restoration of AC
coupled source
The Cat5 Multi Video system is designed to function with DC coupled signals
with the black level referenced to 0 volts. Nearly all VGA cards function this
way. However, some media servers or digital camera devices provide AC
coupled signals and can cause a green color shift in the video. This is a result
of the sync clamping on the Red and Blue channels. The single port
transmitter has been designed with full DC restore capability. A simple switch
setting is all that is required.
The following diagrams show the switch location and settings for the
AC1060A transmitter assembly.
Note: Switch settings other than shown below may result in unpredictable
performance and are not supported by Black Box.
DC restore option:
Enable: Switch position B, C ON (UP)
Disable: Switch position B, C OFF (default)

Appendix D. Rackmounting Units
The Rackmount Kits include brackets for mounting a single transmitter, single
receiver, or a single dual daisychainable receiver. Figure E-1 shows the 1-Unit
Rackmount Bracket (AC1008), which can be used to mount a single CAT5 Multi
VGA System unit on a wall. Figure E-2 shows the 4-Unit Rackmount Bracket
(AC1009), which holds four units in a 19" x 1U rack.
Not shown are brackets for 8 units. The 8 Unit Rackmount Bracket (AC1010) holds
the mounted units like the 4-Unit Rackmount Bracket (AC1009) but is 2U high
instead of 1U high, stacking 4 slots directly above 4 slots.
