2. Introduction
2.1 Overview
The Magenta MultiView™ Series extends VGA and video signals over ordinary
Category 5 cable.
This manual covers Magenta MultiView™ AK500 Series Receivers. These units are
field configurable for various video, audio and serial options. See Appendix C for
configuration settings.
SA series feature video, stereo audio, and RS-232 signals on a single cat5 and SAP
series units are similar to the above but have additional features for pollable serial.
The Magenta MultiView™ AK500 Receiver features integrated skew compensation
that can be turned on for a 10 ns delay per color.
For information on the respective transmitter unit, please refer to the appropriate
manual included with the transmitter.
All models support refresh rates/resolutions up to 2048x1536 @ 70 Hz 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 Equipment You May Also Need
• Audio cable with RCA jacks.
• Video cable with HD15 connectors.
• Serial cable with DB9 connectors.
• CAT5 cable.
2.3 Compatible Cabling
Magenta Research products are compatible with Cat5/5e/6 data cabling as well as
skew free CAT5/5e cabling manufactured for video applications. Note that some skew
free Cat5 is specific to a particular vendor and is not compatible with our products.
Please ensure any skew free CAT5 cable is non-proprietary prior to purchase/
installation.
CAT6 cable, due to the manufacture method, can exhibit much greater skew than
standard CAT5/5e and may require skew compensation beyond what the standard
product offers. Please contact Magenta Research for assistance.
CAT5/5e/6 cabling for the Magenta MultiView™ Series must be pinned to the TIA-EIA
T568B wiring specification (see appendix A) 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
Magenta MultiView™ Series.

CHAPTER 3: SETUP & INSTALLATION
3. Setup and Installation
3.1 Data Mode Configuration (RS232 and SA/SAP versions)
AK500 232 serial receivers are configured in full modem bidirectional serial modes. If
you are using the daisy chain option or a multi-output transmitter (T4,T5) a
MultiView™ CAT5 matrix switch or MultiView™ CAT5 distribution amp, this mode must
be changed to uni-directional broadcast . To do this, configure the internal Serial Digital
Board (SDB) to change the transmitters & receivers serial mode operation (See
Appendix D). This configuration should be done before making any cable connections
and applying power.
Alternatively, remove the internal daughterboard and use the AK500 receivers built in
simplex serial option with the appropriate jumper changes.
SA series offer RS232 serial in addition to stereo audio. The serial signal is 3 wire TX,
RX and does not support full modem signals. Baud rates for the SA series are fixed at
9600. Simplex modes are supported without jumper or other changes by simply using
the TX signal only. SA units require no configuration.
SAP series offer pollable RS232 serial in addition to stereo audio. The serial signal is 3
wire TX, RX and does not support full modem signals. Baud rates for the SAP series
are fixed at 9600. Simplex modes are supported without jumper or other changes by
simply using the TX signal only. See Appendix F on configuration and using SAP
Series.
3.2 Cabling Considerations
• We recommend mounting and connecting all cabling to the Magenta MultiView™
Series 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 (See Appendix A).
3.3 Making the Connections
3.3.1 CONNECTIONS AND SETUP IN GENERAL
This section contains figures showing connections with the specific Magenta
MultiView™ Series models. In general, however, the connection and setup procedure at
both transmitter and receiver ends is as follows:
NOTE: all units must be the same type for all supported features to function correctly.
For example, a UTX 232 must be connected to an AK500 232 for the serial signals to
function. You cannot use the serial option with a UTX 232 and an AK500 that is
configured for simplex serial. Similiary, A UTX SA cannot be used with an AK500A.
Video modes may function normally, but 4th pair options will not.
At the transmitter end (refer to the transmitter user guide) :
1. Connect the source video to the Magenta MultiView™ Series 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.
3. Make your audio or serial connections via the phoenix connector or DB9 connector
as appropriate.
5

MAGENTA MULTIVIEW™ SERIES
24
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 VIDEO OUTPUT HD15 connector to the display unit, and attach
any audio (AUX I/O) and/or serial connections (IOIO) depending on the model of
MultiView™ CAT5 Video System.
2. Connect the CAT5 cable to the LINK INPUT connection. If daisy chaining units,
connect the output CAT5 cable to the LINK OUTPUT connection.
3. Apply power. The LED should light and video should appear on the display
(make sure display is powered ON).
4. To adjust video levels and skew compensation see Section 3.4.
3.3.2 CONNECTIONS ON THE SINGLE-PORT VGA/AUDIO
The single-port units with audio support video 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. You can also use the transmitters and receivers to make video-only
connections without mono audio. Figure 3-1 shows the Single-Port MultiView™ CAT5
Video System with Audio Transmitter connections, and Figure 3-2 shows the receiver
connections.
Figure 3-1. Transmitter connections on the UTx Universal Transmitter.

CHAPTER 3: Setup and Installation
Figure 3-2. Receiver connections on the AK500 with audio.
3.3.3 CONNECTIONS ON THE SINGLE-PORT VGA/RS-232
The Single-Port MultiView™ CAT5 Video System with RS-232 supports video and full-
modem serial (RS-232) signals over CAT5 cable for the AK1000S and the AK1500S.
You can also use the transmitters and receivers to make video-only connections without
serial communications. Figure 3-3 shows the Single-Port MultiView™ CAT5 Video
System with RS-232 Transmitter connections, and Figure 3-4 shows the receiver
connections.
NOTE
Even though both transmitter and receiver units contain audio jacks,
audio is not supported on the RS-232 version. Plugging in audio cables
may interfere with the RS-232 serial communications.

3.3.4 CONNECTIONS ON THE VGA/AUDIO T4/T5 TRANSMITTERS
The T4 four-port transmitter is used when the same signal is distributed
to multiple display devices. You set it up and cable it the same as you would with
the single-port transmitter. Figure 3-5 shows how connections are made on the
audio version, and Figure 3-6 shows how connections are made on the serial RS-232
T4S version.
NOTE
Serial communication mode is unidirectionally broadcast when using T4, T5
transmitters and daisy-chained receivers. In this mode, all other MultiView CAT5
devices must be of the simplex serial type. For more information, contact
Technical Support.

CHAPTER 3: Setup and Installation
3.3.5 CONNECTIONS ON THE SINGLE-PORT VGA SA and SAP
The Single-Port MultiView™ CAT5 Video System SA/SAP series supports RS-232,
video and stereo audio signals over CAT5 cable. SAP offers pollable serial modes so a
bi-directional serial session can be established with a receiver in a daisy chain.
At this time the Magenta MultiView units that support the SA/SAP versions are the
Magenta MultiView UTx Universal Transmitter, AK500, AK1000, and AK1500 receivers.
The Magenta MultiView T4, T5 transmitters do not support SA/SAP versions.
In order to utilize the full potential of the Magenta MultiView SA/SAP series, all
transmitters and receivers must be SA/SAP versions.
You cannot connect a standard RS232 or L/R audio version to an SA/SAP version to
get a single serial or audio signal. Video modes are not affected by this.
Serial signals are 3 wire RS232 (Tx, Rx, ground) and fixed at 9600 baud. Full 9 pin
modem signals are not supported.
Note when using the Magenta MultiView SA/SAP series with a MultiView 9D Cat5 DA,
or Cat5 matrix switch, the serial is transmit only. There are no configuration changes
required to the units. The serial application in use should be changed to transmit only.
Audio is full stereo, line level. One or two separate channels of mono audio may also
be used.
See figures below for cabling connections.
Appendix F details the configuration and use of the SAP series.
NOTE
SA units are pre-configured from the factory and require no configuration
changes.SAP Units require unique addresses when pollable serial is used. See
Appendix F.

3.4 Video Adjustment
3.4.1 Cable Distance Compensation Settings
Before performing the adjustment procedure below, be certain that the MultiView
AK500 Receiver is connected to the CAT5 cable that will be used in your particular
installation. This is because the adjustments are specific to the type and length of UTP
cable being used.
In order to get the highest quality video signals from your MultiView AK500DP, please
follow the instructions and diagrams below:
An image file is available for download at www.magenta-research.com/MV1500test.
bmp to assist in these settings. If the image file cannot be downloaded, use a utility to
draw a black box on a white background.
Before you begin, ensure the EQ Adjust knob is fully counter clockwise and all skew
compensation switches are in the off position.
Turn the EQ Adjust knob clockwise until the shadow next to the black box just
disappears. The brightness in the white area should be the same as the white area
above and below the black box.
3.4.2 Skew Compensation Settings
Skew compensation may be necessary for signal timing differences due to differing pair
lengths within the CAT5 cable. An alternative to using skew compensation is to utilize
Skew Free CAT5 cable. Contact Magenta Research for details.
Using the skew compensation switches, 10 nanoseconds of skew may be compensated
for each color pair.
An image file is available for download at www.magenta-research.com/
MV1500test.bmp to assist in these settings. See Figure 3-2 for an example.
Using the switches, adjust each color to align the Red, Green, Blue lines so that they
are stacked on top each other as a single line.

CHAPTER 4: Troubleshooting
4. Troubleshooting
4.1. Common Problems
In most cases, nearly every issue with the MultiView™ CAT5 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.
• Ensure EQ adjustment is set correctly — turn knob slowly. The
knob is equivalent to 0 feet of cable when fully counter-clockwise
and equivalent to 500 feet of cable when fully clockwise.
• Make sure the CAT5 cable is terminated correctly per the
TIA/EIA 568B wiring specification.
• Is the display device powered on and functioning?
Check to ensure display settings (resolution, refresh rate, etc) are
compatible with input signal.
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: Poor video quality:
Solution: • Have all receiver adjustments been finished (see section 3.4).
• Ensure EQ adjustment is set correctly — turn knob slowly. The
knob is equivalent to 0 feet of cable when fully counter-clockwise
and equivalent to 500 feet of cable when fully clockwise.
• 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. See Section on Skew.
Problem: Poor audio quality:
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.
• Audio is summed left and right for “A” versions. If using a single
channel, both audio inputs must be connected at the transmitter
end for full audio gain. Audio is line level.
• SA serial//audio units support full stereo line level. A high
frequency noise may be heard if the cat5 cable from the
transmitter is disconnected, or the transmitter is not power up.
This is normal. And will disappear once a complete link
connection is made.
• If Daisy Chaining, audio termination must be removed in DP
units. Only the last receiver requires termination. For SA units a
special un-terminated version must be used between
transmitters and the last receiver with a standard End-Of-Line
unit installed at the end. SA units cannot be terminated/
unterminated in the field. This does not apply to SAP units.
11

MAGENTA MULTIVIEW™ SERIES
8
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 RS-232 transmitters or receivers in daisy chains,
Cat5 switches, Cat5 distribution amps, or Multi-output
transmitters, the serial signal is a unidirectionally broadcast
mode only. In this mode, all other MultiView™ CAT5 Video
System devices must be the simplex serial type.
For assistance, contact Technical Support.
• The last device in a T4 transmitter or daisy chain configuration
must be a receiver unit with a terminated serial board.
See Appendix D for Serial board settings.
• For SA units a special unterminated version must be used
between transmitters and the last receiver with a standard End-
Of-Line unit installed at the end. SA units cannot be terminated/
unterminated in the field. This does not apply to SAP units.
• SA/SAP units have a fixed baud rate of 9600 bps and use 3 wire
(TX,RX,GND) signals only.
Problem: “Green shift” or “green washout” on multimedia signals.
Solution: 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
MultiView™ CAT5 Video System UTx Universal transmitter
has been designed with full DC restoration capability. This
problem is easily solved via a simple switch setting in the UTx
Transmitter. Please refer to the UTx Transmitter user manual.

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 MultiView™ CAT5 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.

Appendix D. Serial Daughterboard
(SDB) Settings
The single-port serial transmitters and single-port and dual daisy chainable
serial receivers contain an internal serial daughterboard (SDB) that can be
configured for various serial modes. Multi Port Cat5 transmitters do not
utilize the SDB and are configured for Mode 1 only.
The SDB hardware configuration is done via jumper settings. These jumpers
are used to set the various modes of operation. As shown below. Both ends
must be set the same.
To access the SDB on transmitters and receivers:
1. Make sure the unit is powered OFF
2. If necessary, unplug all cables to the unit.
3. Unscrew the top screw as well as the two set screws in the DB9
connector. Lift the cover off
Table D-1 shows the Transmitter SDB configuration settings.
Notes:
•Mode 1 is required when using multi output transmitters and when
daisy chaining receivers.
•Mode 3 may introduce noise in video over 1,000 ft when serial
communication occurs. This does not apply when mode 5 is used
on the receiver.
•JP1 5-6 and 7-8 terminate the serial bus and must be IN on the
transmitter.

Appendix E. Rackmounting Units
The Rackmount Kits include brackets for mounting a single transmitter, single
receiver, or a single dual daisychainable receiver. Figure F-1 shows the 1-Unit
Rackmount Bracket , which can be used to mount a single unit on a wall. Figure F-2
shows the 4-Unit Rackmount Bracket, which holds four units in a 19" x 1U rack.
Not shown are brackets for 8 units and brackets for AK series receivers and T4
transmitters. The 8-Unit Rackmount Bracket holds the mounted units like the 4-Unit
Rackmount Bracket but is 2U high instead of 1U high, stacking 4 slots directly above 4
slots. The 3-Unit AK receiver and T4 Transmitter Bracket is holds 3 units in a 19" wide
x 1U high panel. The 6-Unit AK receiver and T4 Transmitter Bracket occupies 2U high
rack space stacking 3 units atop 3 units.

APPENDIX F: Pollable Serial Mode
Appendix F. Pollable Serial Mode
The SAP pollable serial daisychainable receivers with video, audio and RS232 serial
feature the ability to open a bi-directional session between a pollable transmitter and a
single pollable receiver in a daisychain installation.
Each pollable receiver must have a unique address set first. Once this has been done,
a special command (discussed below) is sent to the transmitter to specify the receiver
to open a session with. Once this has been done, serial communication can occur
between the RS232 source and display. The transmitter is always addressed 0.
If an address of 0 is sent, the RS232 commands will be broadcast to all receivers.
The following details the installation and setup procedure.
To set the receiver address requires that each internal serial audio daughterboard in
the receiver have a unique address set. This is done via an 8 position dipswitch. Use
the following chart to determine the proper switch addresses. All receivers must have a
unique address. It is recommended to write the address on each receiver once this step
has been completed. It is also recommended to keep a list of receiver addresses and
locations to make it easier to determine which receiver/display is desired to
communicate with.
1) Remove the top cover assembly of the receiver
2) Locate the 8 position dipswitch on the internal daughterboard assembly and using
the following chart, set the receiver address.
3) Replace cover assembly and install unit.
4) See below on using pollable serial mode.
In order to utilize the pollable serial mode in normal operation and connect to individual
receivers, a special command needs to be sent to the transmitter in order to establish a
session between transmitter and receiver.
Follow the steps below to do this (must be done from serial control application in use).
1) To establish a bi-directional RS232 session with a specific receiver, the transmitter
needs the receivers address set. To do this send a CTRL-D <ID> carriage return,
where <ID> is the receiver address (between 1-254)
2) To broadcast serial commands to all receivers, set <ID> to 0.
3) To disable serial communication to all receivers, set <ID> to 255 (to enable serial
communication again, simply set <ID> to a receiver address).
Once a transmitter has the correct ID set, normal bi-directional communication can
occur between transmitter and intended receiver.
