CHAPTER 3: SETUP & INSTALLATION

Product Overview
MultiView™ II DVI-Rx-1K Installation and User Guide 3
Chapter 3 Product Overview
The MVII-DVI-Rx-1K is a video receiver that is compatible with the MVII-DVI-Tx transmitter, and many legacy
MultiView products –contact Technical Support with compatibility questions. It extends an analog video signal
over standard twisted-pair “FTP” type cable. There are user-configurable settings for video, audio, and serial
options which can be controlled from the front panel.
The MVII-DVI-Rx-1K features automatically adjusted EQ and Skew compensation, greatly simplifying the initial
installation and setup. These adjustments can also be fine-tuned manually. The skew compensation can be
varied in 2 ns increments to 65 ns total per color-channel to cancel the effects of skew in Category cables. This
feature allows you to use a variety of UTP cables (both “normal” and “minimized-skew” types) to lengths up to
1000ft (305m).
The MVII-DVI-Rx-1K supports a wide range of video refresh rates and resolutions (refer to Appendix-A).
3.1 Front Panel Interfaces
The front panel of the MVII-DVI-Rx-1K has the following controls and indicators:
There are four buttons (CFG/MODE, SKEW/SEL, DOWN, and UP) and several LED status indicators. All are
used to display and control the operating modes of the receiver, with the LEDs having multiple functions. The
CFG indicator shows these modes:
In normal mode, the CFG indicator is off.
In configuration mode, the CFG indicator will be on.

Twisted-pair Cable Compatibility
MultiView™ II DVI-Rx-1K Installation and User Guide 5
Chapter 4 Twisted-pair Cable Compatibility
The DVI-Rx-1K receiver is compatible with twisted-pair “FTP” type cable. This type of cable ensures best
possible product performance, and maintains EMC compliance for emissions and susceptibility. However, in
applications that must use cable other than “FTP”, it is up to the end-user to ensure product performance at the
intended resolution and distance, and that additional steps are taken to mitigate any RF interference.
In the FTP cable category, there is regular-skew (or IT-grade) cable, and in some areas, “minimized skew”
(video-grade) cable may be available. The DVI-Rx-1K receiver is compatible with both types. Follow these tips
to ensure proper usage of your Category cabling:
Some “low-skew” cable is specific to a particular vendor and is incompatible with our products. Ensure
that any “low-skew”cable is non-proprietary before purchase and installation.
CAT6 cable, due to the manufacture method, can exhibit much greater skew than standard CAT5/5e.
Please contact tech-support for assistance.
Cabling for the Magenta MultiView™ Series must be pinned to the TIA-EIA T568B wiring specification.
We also highly recommend that all 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 cables can damage the Magenta MultiView™ Series.
The cable should be suitably rated Listed cable ( DUZX ) communication cables, TYPE CMP, CMR,
CMG or CM as designated in the NEC.
Cables are to be installed in accordance with the NEC and local building and electrical codes. This is
the responsibility of the end user/installer of this product.
The following figure shows the T568B Wiring specification.

Chapter 5 Installation
This section describes the following installation topics:
Data mode configuration
Prerequisites to installation
Installation procedure
Post-installation adjustments
Post-installation configuration settings
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!
Do not connect DC power until instructed to do so.
5.1 Option-Module Configuration
If you are installing a MVII-DVI-Rx-1K-SAP version receiver (this is equipped with the SAP hardware option
module), then the following information will be important to review BEFORE installing the receiver:
The MVII-DVI-Rx-1K-SAP version offers pollable RS232 duplex serial in addition to true stereo audio. The
serial interface is a 3-wire (TX, RX, GND) interface. The factory-default serial baud rate is 9600 baud, but this is
a user-configurable option using “SAP-II” serial commands. Simplex modes are supported without jumper or
other changes by simply using the TX signal only. The serial-polling capability allows interaction with specific
receivers. This will require that each receiver have a unique SAP-address setting. Please refer to Appendix-B
for (SAP) module configuration information, and Appendix-C for SAP-address settings.
5.2 Prerequisites
Depending on the specific installation requirements, some common tools (screwdrivers, nut-drivers) and related
hardware (mounting screws) might be required. These are not provided with Magenta products.
The following items might be necessary, which are available from Magenta Research:
Audio cable: Phoenix 4-pin to RCA.
Video cable: DVI (or HDMI with an appropriate DVI/HDMI adapter)
Serial cable: Phoenix 4-pin to DB9, or one of several DB9-M/F, M/M or F/F extension cables.
Note: You will need appropriate twisted-pair cable as previously described, to connect the MVII-DVI-Rx-1K to
other MultiView™ II devices. tvONE does not supply this cable.
5.3 Installation Procedure
Ensure that all connectors are clean and free of contaminants prior to making the
connections. Appropriate connector locking hardware (screws/latches) should be used to
prevent cables from disconnecting or causing intermittent operation.
All units must be the same type for 4th-pair supported features to function correctly. For
example, a “MVII-DVI-Tx-A” must be paired with a MVII-DVI-Rx-1K-A, as both must be
identical to work properly. Similarly, an “MVII-DVI-Tx-SAP”can only be used with an MVII-
DVI- Rx-1K-SAP”. Video modes may function normally, but 4th pair options will not.

Installation
MultiView™ II DVI-Rx-1K Installation and User Guide 7
To install a MultiView-II DVI-Tx transmitter:
1. Connect the source video to the Magenta MultiView™DVI-Tx transmitter’s video input port, which is a
DVI-D connector labeled DVI-IN.
2. If desired, attach a local monitor to the DVI-D connector labeled LOCAL OUT (if available).
3. Make your audio or serial connections via the AUX-I/O (Phoenix) connector or DB9 connector as
appropriate.
4. Connect the twisted-pair cable to the transmitter.
5. Apply power to the transmitter.
a. The power-on LED should light up.
b. If there is a local monitor attached, a video image should appear on the
monitor.

Installation
MultiView™ II DVI-Rx-1K Installation and User Guide 8
To install the MVII-DVI-Rx-1K receiver:
1. Connect the DVI OUT connector to the display.
2. Connect any audio and/or serial cables to the (AUX I/O) and (IOIO) connectors, depending on the
specific model of receiver you are installing. Please refer to the –A, -S or –SAP option descriptions for
more information.
3. Connect the twisted-pair cable from a MultiView-II™DVI-Tx transmitter to the LINK INPUT connector
on the receiver.
4. If you are daisy-chaining multiple receivers, also connect the downstream twisted-pair cable to the
LINK OUTPUT port on the receiver.
5. Connect the DC power cable to the POWER port, and check for the following indicators:
The power-on LED should light up (Green).
The CFG indicator is off.
The SKEW/RGB indicator is off.
The EQ/SKEW indicators display the current EQ settings (0 to 100%).
6. IMPORTANT: The MVII-DVI-Rx-1K will auto-adjust the EQ and Skew settings. This is
the factory-default behavior. However, in some applications it will be necessary to
manually fine-tune these adjustments, or leave it in manual-adjust mode after the
initial setup.
7. When the EQ and SKEW settings are properly adjusted, the video should appear on the display (make sure
display is powered ON).
8. Make any other required configuration changes via the LED/button user-interface.
It is critical that the EQ and SKEW settings be adjusted to compensate for the length of the
twisted-pair cable leading back to the transmitter.

5.4 Adjustments
This section describes how to make the following adjustments:
Cable distance (EQ) compensation
Skew compensation
Note that the factory-default behavior of the MVII-DVI-Rx-1K is “auto-adjust mode enabled” for the EQ and
Skew Compensation settings. To exit auto-adjust mode, simply attempt to make a manual adjustment to
either.
To re-enable auto-adjust mode, ensure you are in normal-operation mode and simply push both UP
and DOWN buttons simultaneously and hold for 2 seconds.
5.5 Cable Distance (EQ) Compensation Settings
When the MVII-DVI-Rx-1K is operating in normal mode (CFG indicator is off), it is possible to quickly adjust the
EQ. The EQ/SKEW indicators 1-8 will change accordingly to show (in “bar-graph” form) 0 to 100% of the
available EQ adjustment range.
For best results, use the Magenta EQ/Skew test pattern image if possible. A test pattern
image and video instructions is available at http://www.magenta-research.com/test.
The following figure shows the test image you can use to make the EQ adjustment.
Figure 5: EQ-adjustment test image
To adjust EQ:
1. From normal-mode, press and hold the UP or DOWN button until the SKEW/RGB indicator turns on
(VIOLET). Release the UP or DOWN button.
2. Press the UP or DOWN buttons repeatedly to adjust the EQ setting, either one step at a time or hold
for auto-repeat.
3. To exit EQ-ADJUST mode, leave the buttons untouched for 10 seconds, or press the CFG button
once.
Auto-Adjust EQ should always provide you with a picture out of your receiver. However it may
be possible to get a better quality picture manually. We strongly recommend that all MVII DVI-
Rx units are EQ’d manually once the Auto-Adjust EQ has completed to ensure you get the best
picture possible. This also reduces the time taken for a picture to appear when changing
sources as the AutoEQ algorithm is disabled.

Installation
MultiView™ II DVI-Rx-1K Installation and User Guide 10
5.6 Skew Compensation Settings
The AkuComp-II skew module is already included inside the standard MVII-DVI-Rx-1K receiver. It is possible to
quickly adjust the RGB skew-compensation values when the receiver is operating in normal mode. The
EQ/SKEW indicators 1-8 will change accordingly to show (in “bar-graph” form) 0 to 100% of the available
SKEW adjustment range (0 to 65nSec).
For best results, use the Magenta EQ/Skew test pattern image if possible. A test pattern
image and video instructions is available at http://www.magenta-research.com/test.
The following figure shows the test image you can use to make the SKEW adjustment.
Figure 6: Image Adjustment Utility Skew

5.7 Configuration Settings
There are a number of configurable operating parameters, and the factory-default settings should work for most
applications. However, some applications might require slight configuration changes.
This section describes how to configure the following settings:
Config-mode, LEDs 1-3: 4th pair settings
Config-mode, LED 4: 4th pair termination settings
All settings are available from the front-panel buttons/LEDs. The enclosure does not need to be opened unless
the SAP option module is being installed or removed, or settings specific to the option module need to be
changed.
5.7.1 Configuration Mode
For changing configuration settings, the receiver must be in configuration mode (CFG indicator is on). Once in
configuration mode, any changes are effective immediately and are saved in non-volatile memory.
To enter configuration mode:
Press and hold the CFG button until the CFG indicator is ON.
oOnce in this mode, the LED indicators 1-8 will display the current settings as described in the
tables below.
To exit configuration-mode:
Leave the buttons untouched for 10 seconds. The CFG indicator will turn off (normal-mode).
To quickly reset all user-configurable options back to factory-default settings:
1. Disconnect the DC power cable (or AC power).
2. Press and hold the CFG button.
3. Connect the DC power cable (or AC power). All LEDs blink 3 times, indicating all settings are now changed

5.7.2 4th Pair Settings (LED1-3)
The MVII-DVI-Rx 1K provides several options for using the 4th-pair signals (pairs 1-3 are generally used for
video). The factory-default settings support analog audio (L+R summed) on the 4th-pair. Note that the
connected MultiView transmitter and any daisy-chained receivers must be configured with a matching 4th-pair
operating mode. Otherwise, the desired 4th-pair signal will not work as expected –but the video will not be
affected. Note: If the optional SAP daughterboard is installed then the 4th-pair options are fixed and
unchangeable.
Perform the following procedure while the receiver is in the normal operating state (CFG indicator is off):
Press & hold the CFG button until the CFG indictor is ON. Release the CFG button.
oLEDs 1-8 will show the current value for all configuration settings as bright/off.
Press & release the SKEW/SEL button.
LED indicators 1-3 should be illuminated (either DIM or ON); all others (indicators 4-8) should be off.
Press the UP or DOWN buttons to step through the available 4th-pair settings as shown below.
To leave configuration-mode, leave the buttons untouched for 10 seconds or press the CFG button.

Troubleshooting
MultiView™ II DVI-Rx-1K Installation and User Guide 14
Chapter 6 Troubleshooting
In most cases, nearly every issue with the MultiView™ video system can be resolved by checking the twisted-
pair cable 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. The following table lists the most
common installation errors and their solutions.
Table 4: Troubleshooting Problems and Solutions
Problem
Solution
No video signal at
the receiver
Check that the transmitter is a MultiView-II DVI-Tx type, with the proper option
configured (-A, -S, or –SAP) to match the receiver.
Check that both units are powered and all necessary cables are firmly
connected.
Ensure receiver EQ and SKEW adjustments are set correctly. Use the Auto-
adjust mode (push up + down buttons simultaneously). If a manual adjustment
is necessary, change EQ settings slowly to avoid losing the picture completely.
During initial installation of a MVII-DVI-Rx-1K receiver, it is best to start by
using Auto-Adjust mode. Once you have a video image, it’s much easier to
fine-tune the EQ setting to get the best possible image on your display.
Make sure the twisted-pair cable is terminated correctly per the TIA/EIA 568B
wiring specification.
Check that the display device is powered on and functioning.
Check to ensure your chosen display is compatible with the format of the input
signal at the transmitter.
Poor video quality at
receiver
Ensure receiver EQ and SKEW adjustments are set correctly. Change EQ
settings slowly while making manual adjustments.
Check all cable connections.
There may be a video-skew delay issue –your cable may have more than
65nSec of skew at its current length. If possible, use a shorter cable (or cut off
some excess “service-loop”).
Check the twisted-pair pinout and also the connectors on the transmitter and
receiver for any bent pins or foreign objects wedged between contact pins.
Poor audio quality
The audio output at the receiver is line-level only. An amplifier, or powered
speakers, are required. Make sure amplifier or speaker power is ON.
Check input source levels from the source device. Ensure the audio source
level does not exceed the audio-input ratings for the transmitter (DVI-Tx).
Clipping or distortion can result.
Audio is summed left and right for “A” versions. If using a single channel, both
audio inputs must be connected at the transmitter end to obtain proper audio
gain through the link (approximately 1:1, input to output).
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? Is a null-modem cable required at
the TX or RX end?
When using serial-capable receivers with video switches, distribution amps, or
multi-output transmitters, the serial data is sent transmit-only. Please take this
into account when trying to control displays or other devices. For assistance,
contact Technical Support.
SAP units have a factory default baud rate of 9600 bps and use 3 wire (TX,
RX, GND) signals only. If necessary, use SAP-II serial commands to change
the baud rate to match your connected device.

Chapter 7 Connector Pinouts
DVI-D connector pinout:
DVI (Digital Visual Interface) is a robust and popular video interface standard that can include digital and
analog options in the same connector (the “DVI-I” version). However, as the DVI-Rx-1K is a digital-video only
device, it supports the “DVI-D” subset of the DVI standard interface. The table below provides the pin-out for all
24 pins, which are used in the DVI-Rx-1K unit.
