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) audio connector, phoenix ,  
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:  
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 box. The 1-4 Range LED’s will turn on for indicated  
cable distances. Starting from zero feet to 600 may take some time. Please  
continue turning the knob for best picture quality.  
3. Press and release EQ/Skew knob until the mode LED is green or wait 10 seconds.

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 color pair.  
An image file is available to assist in these settings. See Figure 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 settings.

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:  
Solution:  
No video signal at the transmitter local port or at the receiver.  
• 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:  
Solution:  
Poor video quality:  
Have all receiver adjustments been finished (see section 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:  
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.  
Problem:  
Solution:  
Serial communication doesn’t work correctly.  
• 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:  
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 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:  
Solution:  
Image has purple/blue tint  
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.  
Displays purchased after May 2009 should not require this.  
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.  
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 selected 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 Green = 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 indicates Positive Horizontal sync polarity if fixed sync is enabled.  
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.

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 number of  
5A.  
Please refer to the SAP  
Communication Protocol User Guide  
for information on usage of the SAP  
series commands.
