CHAPTER 2: Introduction

2. Introduction

2.1 Overview

This manual covers the Magenta MultiView™ NEC 600 card slot CAT5 Receiver unit.
The NEC 600 is intended for use only in compatible NEC displays that have the card
slot feature. All signals are input directly into the display so external cabling or power is
not required.

The NEC 600 card slot receiver supports video, stereo audio and the SAP pollable
RS232 option on a single CAT5 cable. In order to support all signals a compatible
SAP series transmitter must be used.
If video only is all that is necessary, any MultiView series transmitter may be used.

The NEC 600 can be controlled and configured via the SAP protocol from a SAP
enabled transmitter.
For information on the usage of the SAP protocol, please refer to the SAP
Communication Protocol user manual.

A CAT5 output is included for daisy chaining.
An external DB9 connector is used for console access to the receiver and is not

intended for RS232 serial communication from a transmitter unit.
The NEC 600 receiver also features integrated skew compensation.
For information on the respective transmitter unit, please refer to the appropriate

manual included with the transmitter.

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 Compatible Cabling

CAT5 cabling for the MultiView™ Series must be pinned to the 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 T568B specification. Using
incorrectly terminated CAT5 cables can damage the Magenta MultiView™ Series.

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.

3. Setup and Installation

3.1 Cabling Considerations

• We recommend mounting and connecting all cabling to the MultiView™ Series
components before applying power.

• Make sure that the CAT5 cable you intend to use has been tested to comply
with the T568B wiring specification (See Appendix A).

3.2 Making the Connections

3.2.1 CONNECTIONS AND SETUP IN GENERAL

This section contains figures showing connections with the specific MultiView™ Series
models. In general, however, the connection and setup procedure at both transmitter
and receiver ends is as follows:

At the transmitter end (refer to the transmitter user guide) :

1. Connect the source video to the 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/serial connections via the 1/8” (3.5mm ) aud io connect or, pho eni x ,
or DB9 serial connector (transmitter model dependent).

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 (Ensure display is powered off and disconnected from AC
power):

1. Remove the left handle on the display and then remove the top option slot blank
cover.

2. Insert the NEC 600 receiver into the NEC display slot and secure with the 2 screws
that secured the blank cover removed in step 1 and replace the handle.

3. Connect the CAT5 cable to the UTP INPUT connection.

4. Connect the AC power and turn display on (Note that the NEC display only
recognizes card slot options only from a cold start (i.e. when the AC power is first
connected and the display powered on, not in standby mode).

5. To adjust video levels see Section 3.3.

6. To set the SAP address for SAP serial transmission, use the two rotary knobs. See
Appendix C and reference the SAP Communication Protocol user manual.

3.3.1 Cable Distance Compensation Settings

In order to get the highest quality video signals from your MultiView CAT5 Video
System, please follow the instructions and diagrams below:
An Image Adjustment Utility is available for download from:
http:// www.magenta-research.com/test
Simply open in any image browser on a computer.
If the image file can not be downloaded, use a utility to draw a black box on a white
background.

NOTE: TURN KNOB SLOWLY DURING ADJUSMENT PROCEDURE. Turning too

fast may result in missing the proper EQ setting resulting in picture loss.

To Reset EQ and Skew values to 0, remove AC power from the display, push and

hold EQ/Skew Knob in and re-apply power to the display.

1. Push EQ/Skew knob in once so that the Mode LED is flashing white.

2. Turn the EQ/Skew 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 bo

CHAPTER 3: Setup and Installation

3.3.2 Skew Compensation Settings

The NEC 600 receiver features integrated skew compensation to adjust for signal
timing differences due to differing pair lengths within the CAT5 cable. Using the delay
signals, skew may be compensated from 2 to 65 nanoseconds in 2 nanosecond
increments on each individual colo r pair.

An image file is available to assist in these settings. See Fig ure 3-4 for an example.

1. To adjust individual colors, press the EQ/Skew knob until the desired color Mode
LED is flashing. The LED color corresponds to the color channel being adjusted.

2. Using the image utility, turn knob to add/subtract delay timing until a single
vertically aligned line of red, green, blue is obtained.

3. When complete press EQ/Skew knob until the Mode LED is green or wait 10
seconds .

Not all colors will have the same delay sett ings.

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 vide o 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.

• 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.

• The NEC 600 only supports RGBHV video modes. Component,
composite or S-video is not supported. This is due to the design on
the option card slot interface and not the NEC 600 receiver.

Problem: Poor video quality:
Solution: • Have all receiver adjustment s been finished (see s ection 3. 3).

• Ensure EQ adjustment is set correctly — turn knob slowly.

• 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.

Problem: Serial communication doesn’t work correctly.
Solution: • Are the serial devices connected properly? Are the serial

parameters correct for source/destination devices?

• SAP units have a default baud rate of 9600 bps and use 3 wire
(TX,RX,GND) signals only.

• Please refer to the SAP Communication Protocol user manual for
information on using SAP series commands.

.

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 XRTx Universal transmitter has been designed
with full DC restoration capability. This problem is easily solved
via a simple switch setting in the XRTx Transmitter. Please refer to
the XRTx Transmitter user manual.

Problem: Image has purple/blue tint
Solution: Display gain may need adjustment. Older displays may have an

incorrect gain adjustment setting. This requires using the remote to
access the “expert mode” . Please contact NEC technical support or
Magenta Research for assistance in this.
Displa ys purchas ed after May 2009 should not require this.

Problem: Notes on Daisy Chaining:
Solution: 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.

• When using NEC600 SAP units, a maximum of 10 units may be

daisy chained within the rated cable length of the receiver if
using standard CAT5/6 or a maximum of 7 units may be daisy
chained within the rated cable length of the receiver if using
skew-free cable.

• Note that if SA/SAP units are used for video only and the SA/

SAP option is not

in use, then you may daisy chain to 12 units.

APPENDIX B: Setting Sync modes

.

Appendix B. Setting Sync Mode

The NEC 600 has the capability for fixed and agile sync. The default sync mode setting
is for agile sync which replicates the source sync polarity signals. However some
displays require a fixed sync polarity that is not possible to change at the video source.
1080P signals may also require this mode if the sync is a very narrow pulse.

The following details how to change the sync polarity of the horizontal and vertical sync
signal. This is only valid if sync mode is set to FIXED (Note that the transmitter must

also be set to the same sync mode—see transmitter user manual. Not all
transmitters support this feature).

To enter Sync Configuration mode, press and hold the EQ/Skew knob for 5
seconds until the Mode LED turns solid white (not flashing).

The Range LEDS (1-4) will indicate which parameter is select ed and its
current value. To change a value, turn the knob. To select the next
parameter, press the knob. To exit , press knob until Mode LED turns green
or wait 10 seconds.

LED 1: Dim green = Agile Sync (default)
Bright Green = Fixed Sync

LED 2: Dim Gree n = Negative Horizontal sync polarity
Bright Green = Positive Horizontal sync polarity

LED 3: Dim Green = Negative Vertical sync polarity
Bright Green = Positive Vertical sync polarity

In normal operation, the Range LED’s also indicate which sync mode is in use:
LED1: Off indicates Agile, non-fixed sync mode (default)

On indicates Fixed sync mode in use.
LED2: On indic ates Pos itive Horizont al sync polarit y if fixed sync is enable d.

Off indicates Negative Horizontal sync polarity if fixed sync is enabled.
LED3: On indicates Positive Vertical sync polarity if fixed sync is enabled.

Off indicates Negative Vertical sync polarity if fixed sync is enabled.

NOTE: When in Sync Configuration mode, pressing the knob past LED3 will
result in all LED’s being off. This is a special video voltage offset mode that is
currently not implemented. It is important that the knob not be turned when in
this mode as you could change the video voltage level and affect picture quality.
If this does happen, please turn the knob fully counterclockwise to restore the
video voltage level to its default state.

MAGENTA MULTIVIEW™ SERIES

Appendix C. SAP

Addressing

To set the NEC600 SAP address, use
the two rotary address knobs on the
unit. You will need to convert the
decimal address desired to a
hexadecimal address using the table to
the right.
The left knob designated H is the most
significant digit, while the right side
designated L is the least significant
digit.

For example, to set a decimal address
of 90, the knobs should be set to H=5
and L=A, for a hexadecimal num ber of
5A.

Please refer to the SAP
Communication Protocol User Guide
for information on usage of the SAP
series commands.
