CHAPTER 2: Introduction.
2. Introduction
2.1 Overview
The MultiView™ Octet System supports RS-232, video and stereo audio signals over
CAT5 cable. The Octet SAP RS-232 serial protocol offers pollable serial modes so a bidirectional serial session can be established with a single receiver attached to the Octet
or a receiver in a daisy chain that is attached to the Octet.
In order to utilize the full potential of the Magenta MultiView Octet, all receivers must be
SAP versions.
Non SAP receivers may be utilized for video only applications.
Video signals supported include RGBHV, Component (HD/SD formats) as well as
composite and S-Video (adapter cables may be required).
Serial signals are 3 wire RS-232 (Tx, Rx, ground, 8-N-1).
Note when using the Magenta MultiView Octet and SAP series receivers with a
MultiView 9D Cat5 DA, or Cat5 matrix switch, the serial is one way 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.
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 3.5 mm 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.

MAGENTA MULTIVIEW™ SERIES
3. Setup and Installation
3.1 Data Mode Configuration
SAP series offer pollable RS232 serial in addition to stereo audio. The serial signal is 3
wire TX, RX, GND and does not support full modem signals. Baud rates for the SAP
series selectable from 1200 to 115k . Simplex modes are supported without jumper or
other changes by simply using the TX signal only. See Sections 3.3.3, 3.3.4 and
Appendix B on configuration and use of Octet and SAP series receivers
3.2 Cabling Considerations
• We recommend mounting and connecting all cabling to the Magenta MultiView Series
components before applying power.
• Make 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
In order to setup and use the MultiView Octet transmitter:
1. Connect the source video to the Magenta MultiView Octet video input port which is
an HD15 connector labeled VIDEO IN. For RCA or BNC signals, an adapter cable may
be required. Contact Magenta Research for details
2. If desired, attach a local monitor via the local monitor port to the VIDEO OUT port or
use this port to cascade into another Octet (up to 5 units may be cascaded this way).
3. Make your audio and serial connections via the 3.5 mm stereo input and DB9
connector as appropriate. The AUDIO OUT and SERIAL OUT may be cascaded to
other Octets as necessary (up to 5 units).
4. Connect the CAT5 cables from the receivers to the CAT5 OUTPUTS of the Octet.
5. Apply power on the transmitter. The power LED should light and if there’s a local
monitor attached a video image should appear on the monitor’s screen.
6. Install receiver units per the instructions in the respective receiver user manual.
Ensure each receiver has a unique address (see receiver manual or Appendix B).
7. Set up the Octet using the LCD screen and menu options. See Section 3.3.3.
The Octet may also be setup and controlled serially. See Section 3.3.4.
Refer to Sections 3.3.5 for use and operation of the Octet

CHAPTER 3: SETUP & INSTALLATION.
3.3.2 CONNECTIONS ON THE OCTET
The Octet supports a variety of video modes from composite, S-video, Component and
RGBHV. Adapter cables may be necessary to connect to the HD15 video input. Audio
signal is line-level stereo and powered speakers are required. Serial protocol is 3 wire
Tx, Rx, Gnd 8-N-1.
Figure 3-1 shows the Octet cable connections.
Note that the VIDEO OUT, SERIAL OUT, and AUDIO OUT may be used to cascade to
secondary Octets. The video and audio outputs may also be connected to an external
display monitor and powered speakers local to the Octet. A maximum of 5 Octets may
be cascaded together.

CHAPTER 3: Setup and Installation.
3.3.3 OCTET SETUP and CONFIGURATION
DC Restore Mode:
This screen shows current DC Restore mode settings. DC Restore modes are used to
correct for AC coupled video signals on the transmitter input (Note: AC Coupling must
be turned on by selecting AC mode in AC Coupling screen. See AC Coupling
parameters). Also see Section 4, Troubleshooting for more information. DC Restore
modes may be changed at will and go into effect immediately. A power cycle is not
required.
Modes are:
00 = DC Restore OFF (default)
01 = DC Restore Mode 1
02 = DC Restore Mode 2
Press the OK button to select desired value.
AC Coupling:
This screen works in conjunction with the DC Restore mode discussed previously.
In order to use DC Restore modes 1,2 AC Coupling must be set to AC. The default
video mode is DC. Use the UP/Down buttons to select desired setting, then press the
OK button.
However, AC coupling may be used by itself in non-RGBHV modes such as YUV video.
Sync problems can occur if this mode is ON, DC Restore is set to OFF when RGBHV
video is used.
Sync Mode:
This screen is used to change the H/V sync mode in RGBHV signals.
In most cases, the default value of Agile sync will work fine. However there are times
when a signal (especially a 1080p signal) may require Fixed sync mode.
NOTE: ALL receivers must also be set to Fixed sync mode for the system to
function properly. See appropriate receiver manual for details. Not all receivers
support fixed sync modes.
Once desired sync mode is selected, press OK button to store in memory.
Baud Rate:
This screen can be used to change the baud rate on the Octet’s serial input port
NOTE: This only affects the incoming Octet Serial ports. It does not change the
receivers baud rate. It is not recommended to change the incoming baud rate unless
absolutely necessary as it is possible to saturate the communication link to the receiver
resulting in data over runs and data loss.
To change the baud rate, use the UP/DOWN buttons to select desired value, then press
the OK button to set it. The default baud rate is 9600.
Source Address:
This screen configures the serial address of the Octet. This address is used to
establish a serial session with a receiver. This address must be unique and in the range
of 0-255 (or if cascading Octets, address+256*Octet_ID number)
This address will also appear in the Status screen.
If multiple Octets are serially cascaded, each Octet must have a unique address. This
will reduce the number of addresses available for receivers.

MAGENTA MULTIVIEW™ SERIES
3.3.3 OCTET SETUP and CONFIGURATION
Destination Address:
This screen sets the address of a receiver to which the Octet will establish a serial
session with. All serial commands sent to the SERIAL IN port will pass to this receiver.
This may also be accomplished via a keyboard command as detailed in the next section
The default value is 0.
Note that this value is not retained in memory and will revert to the default value after a
power cycle.
Use UP/DOWN buttons to select and press OK when done.
Copy DDC:
This screen will initiate a DDC copy of the display connected to the VGA IN port.
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.
To copy a particular display’s DDC:
Remove the Source input signal and temporarily connect the desired display.
Press the OK button in the Copy DDC LCD screen on the Octet to start the copy
sequence. Once the DDC information has been copied, the monitor can be removed.
The new DDC will be stored into the Octet memory.
The Octet features a generic DDC as a default. This can be restored using the
command below. This DDC supports popular VESA standards in standard and
widescreen formats.
Restore DDC:
To restore the Octet’s generic default DDC, press the OK button in this screen.
Set Attention Character:
The attention character is the special code that is used to communicate with the Octet.
When sending Octet specific commands this character sequence must be used.
This is a one character sequence of Control-A through Control-Z (or 01h to 1Ah)
NOTE: This code is sent once to the Octet in order to establish communication with the
intended receiver. Once a session has been established with a specific receiver normal
serial control source to device may commence without further formatting.
The default value is control-X (18h). This may be changed to one of 26 possible letters
of control-A to control-Z. Note that this control code will not be passed by the Octet to a
receiver. If the device being controlled requires specific control codes such as Ctrl-M
(carriage return), ensure this value is not used as the Octet attention code.
Pass-through mode:
When the pass-through mode is enabled, the Attention character and all Octet
commands are ignored. Serial communication is passed directly to all devices in the
system in broadcast mode. This is useful if a third party display addressing system is
utilized.

The LCD will display RESET ALL. CONFIGURATION SAVED when complete.
3.3.4 OCTET SERIAL COMMANDS
The Octet can be configured via the serial port also, as follows:
Sending Commands:
All Octet commands are preceded by an “attention character”, which is factory-set to
control-X (18h). It is possible to change the attention-character through the Octet’s
serial port or LCD display. In the following command set description, this character is
represented by: <ATTN>.
Note: When using a Windows terminal application to send commands, it is helpful to
configure it so that it will “Append line feeds to incoming line ends”.
Addressing Rules:
SAP-receivers have an 8-bit “device address” which can be set with a DIPswitch on the receiver. There are some special rules concerning how
receivers behave depending on their address:
Receiver
Address
0
Behavior
Receives broadcast-session data.
Able to respond if there is a broadcast-session active.
1…255 Receives broadcast-session data.
Does not respond if there is a broadcast-session active.
Receives device-session data.
Only able to respond if there is a Device-session active.
There are several types of communication sessions:
·
Device-session.
One Octet communicates specifically with one receiver.
·
Group broadcast:
One specific Octet broadcasts to all receivers attached directly to it.
·
Global broadcast:
All Octets broadcast to all receivers attached to them.

MAGENTA MULTIVIEW™ SERIES
Octet serial commands:
Device-session:
The one-to-one communication session is established using this command sequence:
Command:
Response:
<ATTN>Da<CR>
none (individual session is activated)
a = device address. Range = “1” to “255” (ASCII encoded).
Note: For cascaded Octet units, add (256 * Octet_ID) to the device address.
Consider an Octet cascade-configuration of 5 units, with ID’s 0, 1, 2, 3 and 4:
To establish a session with remote ID “3” attached to Octet unit ID
“4”, the address field will need to be: (3 + (256 * 4)) = 1027.
Note: Only receivers set to the specified address in this command will be
able to respond.
Group Broadcast:
Generally this is used to send a message to all receivers simultaneously when a
specific response isn’t required. When using cascaded Octet units, add “256*Octet_ID”
to the address field for every Octet unit beyond the base unit.
Command:
Response:
<ATTN>Da<CR>
none (group session is activated)
a = 0 + (256 * Octet unit ID)
Note: Only receivers set to address-0 will be able to respond however all
receivers attached to the selected Octet unit will receive the message. Use
with caution – you may need to have “addressable displays” in the system.
Global Broadcast:
Generally this is used to send a message to all receivers in the entire system (across all
Octet units) simultaneously when a specific response isn’t required.
Command:
Response:
<ATTN>D*<CR>
none (global session is activated)
Note: Only receivers set to address-0 will be able to respond however all
receivers in the system will receive the message. Use with caution – you may
need to have “addressable displays” in the system.
Lock Front Panel Buttons:
Command:
Response:
<ATTN>L<CR>

@<CR>
The string will override the idle-screen display. The string can be up to 32
characters.
Characters 1-16 will display on line-1, characters 17-32 will display on
line-2.
A string shorter than 32 characters will be padded with trailing spaces on
the LCD.
For example, to display this message on the LCD:
This is a test 1
This is a test 2
Send the command: <ATTN>WThis is a test 1This is a test 2<CR>
Restore LCD default display:
Command:
Response:
<ATTN>W<CR>
@<CR>
Set Octet’s ID number:
Command:
Response:
<ATTN>Sa<CR>
@<CR>
a = 0 to 255. There can be up to 256 Octet units in one cascade configuration.
For example, to set the ID to 12, send the command <ATTN>S12<CR>
Note:
·
The ID number can also be set through the front-panel LCD menu
interface.
Caution: To prevent assigning multiple Octets the same ID, use this command
only when they are not serially-cascaded. In other words – do one box at a
time.
Read Octet’s ID number:
Command:
Response:
<ATTN>A<CR>
Saaa@<CR>
aaa = 000 to 255. Note: This response is always padded with leading zero’s.
Caution: Use this command only when connected directly to a single Octet.
Do Not send this command to a group of serially-cascaded Octets because
the result will be indeterminate.

CHAPTER 3: Setup and Installation.
Octet serial commands:
Set Sync-mode mode:
Command:
Response:
<ATTN>Yx<CR>
@<CR>
x = Sync-mode:
0 = Agile-sync mode (RepliSyncÔ)
1 = Fixed-sync mode
NOTE: ALL receivers must also be set to Fixed sync mode for the system to
function properly. See appropriate receiver manual for details. Not all receivers
support fixed sync modes.
Set Octet baud-rate:
Command:
Response:
<ATTN>Bx<CR>
@<CR>
x = Baud-rate:
1 = 1200
2 = 2400
3 = 4800
4 = 9600
5 = 14.4K
6 = 19.2K
7 = 38.4K
8 = 57.6K
9 = 115.2K
Note: The “@” acknowledgement character is transmitted at the current baud
rate, then the baud-rate change becomes effective. All subsequent
communications take place at the new baud rate.
This only affects the incoming Octet Serial ports. It does not change the
receiver’s baud rate. It is not recommended to change the incoming baud
rate unless absolutely necessary as it is possible to saturate the
communication link to the receiver resulting in data over runs and data loss
If different baud rates are used throughout the system.
Set Remote-device baud-rate:
Command:
Response:
x = Baud-rate:
<ATTN>Rx<CR>
@<CR>
1 = 1200
2 = 2400
3 = 4800
4 = 9600
5 = 14.4K
6 = 19.2K
7 = 38.4K
8 = 57.6K
9 = 115.2K
Note: To set a remote device’s baud-rate, a session must first be established
with the device using the “D” command. The group and global addressing
rules apply as well. Therefore, it’s quite possible (and perfectly useful) to
globally set every remote device to the same baud rate using this command.
It is not recommended to change the incoming baud rate unless absolutely
necessary as it is possible to saturate the communication link to the receiver
resulting in data over runs and data loss If different baud rates are used
throughout the system.
It is possible to have different baud rates set on different receivers. Generally
it is good practice to set all units to have the same baud rate.

MAGENTA MULTIVIEW™ SERIES
Octet serial commands:
Remote-device echo:
Command:
Response:
<ATTN>Pc<CR>
@<CR>c
c = single ASCII character
Note: The character is transmitted to the previously addressed remote device.
The remote device, if present and operating properly, will immediately echo
that single character. This is the only way to know if a particular SAP receiver
is plugged-in and working. It does not require a display to be attached to the
receiver’s serial port (this is a software-loopback function). The character
should be a printable ASCII character – not a control character.
Set Attention Character:
Command:
Response:
<ATTN>Tc<CR>
@<CR>
c = Attention character:
A = Control-A
B = Control-B
C = Control-C
D = Control-D
…
X = Control-X (factory default value)
Y = Control-Y
Z = Control-Z
Note: After the “@” acknowledgement character is transmitted, all subsequent
communications must use the new attention character value.
For example, to set the attention character to control-D (currently set to
control-X):
Command:
Response:
<Ctrl-X>TD<CR>
@<CR>
From this point forward, all commands must begin with <Ctrl-D>
The default value is control-X (18h). This may be changed to one of 26 possible letters
of control-A to control-Z. Note that this control code will not be passed by the Octet to a
receiver. If the device being controlled requires specific control codes such as Ctrl-M
(carriage return), ensure this value is not used as the Octet attention code.

3.3.5 OCTET OPERATION
Each SAP receiver as well as each Octet must have a unique address. Once this has
been done, a special command (control-X and the letter D) is sent to the Octet to
specify which receiver to open a session with. At this point, normal serial
communication can occur between the RS232 source and display.
See Appendix B on how to set the receiver address.
Each Octet manages receivers in address ranges of 1-255. In order to establish
communication with receivers connected to each Octet, the following formula must be
used to calculate an offset to add to the desired receivers address. This is based upon
each Octet’s address ID so you need to know which receivers are connected to each
Octet.
Octet offset = (Octet_ID x 256)
where Octet_ID is the address of the Octet.
This must be added to the desired receiver’s address in order to communicate with it.
Example 1: A single Octet addressed as 10 with 8 receivers connected.
Receiver addresses are 21-28.
To connect to the receiver addressed 25, the command would be
Ctrl-XD2585 (10*256+25=2585)
Example 2: Two Octets cascade, the first Octet has address 10, the second has
address 11. Both have eight receivers, addressed 21-28.
To connect to receiver addressed 25 on the first Octet, the command
would be Ctrl-XD2585 (10*256+25=2585).
To connect to a receiver addressed 25 on the second Octet, the command
would be Ctrl-XD2841 (11*256+25=2841)
In order to utilize the pollable serial mode and connect to individual receivers, a special
command needs to be sent to the Octet in order to communicate with a receiver. This is
done by the serial application in use prior to sending commands to the device.
This command is only required once and remains in effect until a different receiver is
chosen.
Once the session has been established all serial communication is sent straight to the
destination device without further formatting or special control codes.
Follow the steps below to do this:
1)
To establish a bi-directional RS232 session with a specific receiver, the Octet
needs the receivers address set. To do this send a CTRL-X D<ID> <carriage
return>, where <ID> is the receiver address plus the Octet_ID offset
2)
To broadcast serial commands to all receivers on a specific Octet, set <ID> to
(Octet_ID x 256). Or set ID to the asterisk (*) to braodcast all receivers on all
Octet’s.
3)
To disable serial communication to all receivers, set <ID> to an unused receiver
address such as 255 (to enable serial communication again, simply set <ID> to a
functioning receiver’s address).

4. Troubleshooting
4.1. Common Problems
In most cases, nearly every issue with the MultiView Octet 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:
Solution:
No power LED.
• Check fuse on back on unit. Replace with 2A type.
Problem:
Solution:
Octet gets warm during operation/fan noisy.
• Check air filter over fan. Remove and clean as necessary.
Problem:
Solution:
No video signal at the Octet local port or at the receiver.
• Check that both units are powered.
• Ensure EQ adjustment is set correctly on receiver.
• 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.
• There may be a DDC compatibility problem. See sections 3.3.3
and 3..3.4 on copying a display DDC.
Problem:
Solution:
Poor video quality:
• Have all receiver adjustments been finished.
• Ensure EQ adjustment is set correctly on the receiver.
• 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 receiver manual for
skew compensation options/settings.
• There may be a DDC compatibility problem. See sections 3.3.3
and 3..3.4 on copying a display DDC.
Problem:
Solution:
Poor audio quality:
• 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.

CHAPTER 4: Troubleshooting
.
Problem:
Solution:
Serial communication doesn’t work correctly.
• 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.
• Ensure the correct receiver has been properly set via the Set
Remote Unit Address command and has the proper serial address
configured.
Problem:
Solution:
“Green shift” or “green washout” on multimedia signals.
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 Octet transmitter has been designed with full DC
restoration capability. This problem is easily solved
via a simple setting in the Octet configuration screen. Please refer to
Section 3.3.3, AC Coupling and DC Restore options.
Problem:
Solution:
Notes on Daisy Chaining:
When daisy chaining, the maximum cable distance is not increased
beyond the rated distance of the receiver used. For example, an
AK600 can only daisy chain within 600 ft of the transmitter.
It is possible to daisy chain out of a short range receiver into a longer
range receiver to increase the range. For example, over 600 ft an
AK600 can be daisy chained into an AK1200 which allows for daisy
chaining to 1,200 ft.
A maximum of 12 units may be daisy chained together. If a unit in the
middle of the chain loses power or is disconnected from the chain, all
units after this will lose all signals.

Appendix B. Pollable Serial Mode
In order to fully utilize the addressable serial features of the Octet and SAP series
receivers each receiver and Octet must have a unique address set first.
The following details the installation and setup procedure.
To set the Octet ID, please use the LCD menu or appropriate serial command as
detailed in sections 3.3.3 and 3.3.4. All Octets must have a unique address.
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 and Octets
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.
** Do not set any receivers to address 0 **
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.
Each Octet manages receivers in address ranges of 1-254. In order to establish
communication with receivers connected to each Octet, the following formula must be
user to calculate an offset to add to the desired receivers address. This is based upon
each Octet’s address ID so you need to know which receivers are connected to each
Octet.
Octet offset = (Octet_ID x 256)
where Octet_ID is the address of the Octet.
This must be added to the desired receiver’s address in order to communicate with it.
Example 1: A single Octet addressed as 10 with 8 receivers connected.
Receiver addresses are 21-28.
To connect to the receiver addressed 25, the command would be
Ctrl-XD2585 (10*256+25=2585)
Example 2: Two Octets cascade, the first Octet has address 10, the second has
address 11. Both have eight receivers, addressed 21-28.
To connect to receiver addressed 25 on the first Octet, the command
would be Ctrl-XD2585 (10*256+25=2585).
To connect to a receiver addressed 25 on the second Octet, the command
would be Ctrl-XD2841 (11*256+25=2841)
