Troubleshooting:
In most cases, issues with MultiView can be resolved by checking the CAT5/5e/6
cable termination and ensuring it is pinned to the specification shown in
Appendix A. Below are the most common installation errors:
No video signal at transmitter local port and/or at receiver :
- Check that both units are powered.
- Ensure that the CAT5/5e/6 cable is terminated correctly per the specification
shown in Appendix A.
- Check that the display device is powered on and functioning.
- In some cases, the sync termination may be mismatched. MultiView ships with
75 Ohm termination as the default. See Appendix B to disable termination.
Poor video quality:
- Ensure the compensation switch on receiver is in the correct position.
- Check cable connections.
- Refresh rate of video signal may be set too high.
- Delay Skew issue; see section titled “Delay Skew in UTP cables”.
Poor audio quality:
- Amplified speakers are required. Ensure speaker power is on.
- Check input source levels from source device. Make sure the audio source is
not over or under driven.
- Supported audio signals are line level, unbalanced (contact Magenta Research if
mic/speaker levels are required).
Serial communication does not work correctly:
- Ensure serial devices are connected properly and serial parameters are correct
for source/destination devices.
- Ensure serial cables are terminated correctly. If a Null Modem cable is used, it
must be placed at the Receiver end.
- When using UTx transmitters in simplex Uni serial mode or T4 Transmitters or
DP Receivers the serial signal is a unidirectional broadcast mode only. In this
mode, all other MultiView devices must be simplex serial type. Contact Magenta
Research for assistance.
- The last device in T4 or DP mode must be a standard or DP Receiver unit with
a terminated Serial Board. Contact Magenta Research for assistance.

Troubleshooting (con’t):
Green Shift / Green Washout on Multimedia Signals:
The standard MultiView is designed to function with DC coupled signals with the
black level referenced to 0 volts. Nearly all VGA cards function this way.
However, some media servers or digital camera devices 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 in the MultiView. The MultiView UTx
Universal transmitter has been designed with full DC restore capability. A simple
switch setting change is all that is required. See Appendix C for details.
Appendix A:
T568B CAT5/5e/6 Wiring Specification
NOTE: This equipment is not intended for, nor does it support distribution
through an Ethernet network. Do not connect these devices to any
sort networking or telecommunications equipment.
Delay Skew in UTP cables:
Propagation Delay is the time needed for the transmission of a signal over a single
pair. Delay Skew is the difference in Propagation Delay between any two
pairs within the same cable sheath. In UTP, delay skew is caused by the differing
twist rates of the individual pairs. Manufacturers of UTP intentionally vary the
twist rate between pairs to improve crosstalk characteristics. The difference in
twist rates is greater in CAT5e than CAT5 and even greater in CAT6. This
improves performance in digital applications but can hamper performance in certain
analog video transmission applications. There is no apparent sense of consistency
between manufacturers with regard to the twist rates. Paradoxically, our
studies have revealed that the skew issue becomes progressively worse with
“higher” performance and more expensive cables!
Magenta Research has recognized the skew issue since the inception of video
over UTP technology. Because of our awareness in this regard, we have
designed the cable equalization network in the MultiView 450 product to work
with less expensive UTP cables. Magenta Research has determined that
Comtran currently manufactures one of the most cost effective and best performing
CAT5e cables. Current Comtran part numbers for this cable are #2881
non-plenum, and #2347 for plenum rated versions. For distances less than 500
feet or so and for horizontal scan rates of less than 80 kHz, no additional means
for skew compensation should be necessary.
If using the Magenta Research AK1000 or AK1500 series of long range receivers,
it may be necessary to compensate for skew rates in the CAT5/5e/6 cable. There
are two solutions; one solution is to purchase the Akucomp skew compensation
option for the AK series receiver. The other solution is to use certified skew free or
low skew cable. Belden Cable carries a line of skew free and low skew cable that
is specifically designed for A/V applications. Contact Magenta Research for details.

Setting Sync Signal Output Termination:
Appendix C:
DC Restore to fix Green Shift of AC coupled signals
In some cases it may be necessary to change the 75 Ohm termination of the
sync outputs on the MultiView units.
This can be accomplished by opening the unit and installing jumpers on the circuit
board.
The settings will disable/enable the 75 Ohm termination on individual units, i.e.
changing a transmitter will affect the local monitor port only and not affect
receivers. Likewise, changing a receiver will affect the output port of the receiver
and not affect the transmitter.
The following diagrams show the jumper locations for the UTx Universal
Transmitter assembly.
The standard MultiView product is designed to function with DC coupled signals
with the black level referenced to 0 volts. Nearly all VGA cards function this way.
However, some media servers or digital camera devices 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 in the MultiView. The MultiView UTx
Universal transmitter has been designed with full DC restore capability. A simple
switch setting is all that is required.
The following diagrams show the switch location and settings for the UTx
Universal Transmitter assembly.
Note: Switch settings other than shown below may result in unpredictable performance
and are not supported by Magenta Research.
