MultiView II T4 Transmitter: Quick Start Guide
The Magenta MultiView™ II T4 transmitter extends an analog video signal over standard CAT5 cable (also
CAT5e and CAT6), provided over 4 link outputs. There are user-configurable settings for video, audio, and serial
options which can be controlled from the front panel. For more details please refer to the complete MultiView™ II
T4 User Guide, available for download at www.magenta-research.com, or scan the QR-code shown here to access the
user guide directly:
Required Tools / Hardware / Materials: Tools include appropriate screwdriver(s) and mounting hardware
(optional, for example: rack-mount, wall or under-desk mounting). Required materials include appropriate cables for your specific
application.
PRECAUTIONS: (1) Do not apply AC power until instructed to
do so. (2) 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! (3) Use only Magenta
Research LTD approved MultiView™ II power adapters. Failure
to do so may damage this device and will void the warranty.

(Optional) Depending on installation requirements: At any
time during installation, the transmitter may be securely
mounted using appropriate brackets and hardware.

Video-status and
DDC-copy indicator
Power-up Check: After all signal and power cables are connected, then apply AC power. The power-on indicator should light. If the
video source is providing a valid VGA (RGB+HV) video signal, the video-status indicator should also be on (for any other type of video
signal this status indicator will always be off). If there is a local monitor attached, a video image should appear on the monitor. If there is
no image on the display, recheck all cables and ensure the display is turned on.
Front Panel Controls: (Refer to Figure-2) There are two buttons (COPY/CFG and DDC MODE/SEL), and several green LED status
indicators. These are used to control the operating modes of the transmitter, and to display current status. In “normal-mode”, the CFG
indicator is off. In “configuration-mode”, the CFG indicator is on or flashing.
DDC Mode Selection: When the T4 transmitter is operating in normal-mode (CFG indicator is off), it is possible to quickly select
between the 3 DDC operating modes simply by using the DDC MODE button at any time:

STD: Selects the Magenta Magic DDC profile. Press the DDC MODE button until the STD indicator (LED 6) is on. The
Magenta Magic profile is a default set of common video resolutions. This is the factory default setting.

LOCAL: Selects the DDC profile from a locally-connected display. Press the DDC MODE button until the LOCAL
indicator (LED 7) is on. The LOCAL mode allows the video source device to directly read the DDC profile from the locally
connected-display (if present). Note that LOCAL mode does not store any DDC profile information inside the T4 device.
 COPY: Selects a previously stored copy of a DDC profile. Press the DDC MODE button until the COPY indicator (LED8) is
on. To use the COPY mode, a DDC profile must have already been read and stored into the T4.
To perform a DDC-copy operation: Ensure the COPY mode is selected (LED8=on), then: 1) Connect a display to the
LOCAL OUT port. (2) Push and hold the COPY button until the copy-status indicator flashes 3 times, indicating a successful
operation. If it only flashes once, the operation failed and the previously stored DDC profile (if any) will remain unchanged.

Changing Internal Settings: In configuration-mode (CFG indicator = on or flashing), the CFG and SEL buttons, plus the LED
indicators (1-8) will allow you to change internal configuration settings. The changes are effective immediately and are saved in nonvolatile memory.

To enter configuration-mode-1: Press CFG button once. The CFG indicator will turn on, confirming you’re in configurationmode-1. Once in this mode, the LED indicators 1-8 will display the current settings as described in the tables below.

To enter configuration-mode-2: Press CFG button twice. The CFG indicator will flash, confirming you’re in configurationmode-2. Once 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).
Configuration Mode-1, Sync-mode Options: The T4 is factory-configured for auto-detecting the proper sync-mode (RepliSync-I
normal/stretched). This mode is generally compatible with all existing MultiView receiver products that support RepliSync (if they are
also using their default settings). However, some video sources may require a custom sync-mode setting (especially at 1080p and
1920x1200 video resolutions). For these cases, one of the other sync-modes can be selected. Note that any connected MultiView
receiver MAY also require a change to its sync-mode settings. Otherwise, you may not get a proper video display output at that
receiver.
 (starting in normal-mode) Press and release the CFG button once to access configuration-mode-1. CFG indicator = on.
 Press and release the SEL button once. You will now be able to change sync-mode settings.
 LED indicators 1-3 should be illuminated (either DIM or ON); all others (indicators 4-8) should be off.

Configuration Mode-1, 4th Pair Options: The T4 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 any connected MultiView
receiver must be configured with a matching 4th-pair operating mode. Otherwise, the desired 4th-pair signal will not work as expected.

Troubleshooting: In many cases, problems encountered when installing MultiView™ II extension products can be resolved by
checking the CAT5 cable termination. It must be pinned out according to the TIA/EIA 568B standard wiring specification. For additional
troubleshooting information or to obtain the TIA/EIA 568B wiring specifications please refer to the MVII-T4 User Guide, downloadable
from www.magenta-research.com, or scan the QR-code shown here to access the user guide directly:
