1 About this Guide
This user’s guide explains how to use the MSD-701UHD / 702UHD / 801UHD / 802UHD digital multi switcher
(hereafter referred to as “MSD”), which have a scan converter. The MSD series is divided into four models as
shown in the table below.
Since descriptions in this document are for MSD-802UHD, there may be slight differences between the model
and other models.

3 Product outline
The MSD-701UHD / 702UHD / 801UHD / 802UHD are high-performance digital multi switchers with a built-in
scan converter.
The following input signal formats are supported: HDMI, DVI, composite video, S video, analog RGB, and
analog YPbPr signals. All input video signals are converted to HDMI signals and output at user definable
resolution formats up to 4K@60.
MSD-801UHD and MSD-802UHD include front panel HDBaseT input in order to provide power to the
transmitter that support PoH (Power over HDBaseT).
For audio input and output, digital audio and analog audio formats are supported, and they are cross-routable.
Audio levels of each input and output can be set individually. The lip sync feature provides the user with a
means to control time alignment between the video and audio.
The MSD is controlled remotely via RS-232C or LAN. Additionally, external devices connected to the MSD
can be controlled through RS-232C, LAN, CEC, or contact closure by registering external control commands.
The waiting function can delay the issuance of registered commands to external devices. As an example, a
power down command can be delayed until after sufficient lamp cooling time for a projector has elapsed.
Control commands for external devices can be executed from front panel keys or in response to commands
via RS-232C or LAN. Commands can also be executed when input channel selection keys are operated or
the MSD is powered ON.

6 System configuration example
Configuration example: source and sink devices are connected to the MSD.
Use a transmitter that supports PoH PD (IEEE802.3af) and AWG 24 twisted pair cable or thicker cable in
order to provide power from the HDBaseT input connector on the front panel to the twisted pair cable
transmitter.
For long reach mode, please use the MSD with IDK’s twisted pair cable transmitter or receiver.

7 Precautions
Before connecting to external devices, follow the precautions below.
7.1 Installation
When installing the MSD, please observe the following precautions.
●Do not stack or place one MSD directly on top of another MSD.
●Do not block vent holes. To provide adequate ventilation, maintain sufficient clearances around the
MSD 1.18 inches (30 mm).
●When the MSD needs to be mounted in an EIA rack, or an enclosed space, please ensure that
sufficient ventilation or cooling is provided and that the ambient temperature will not exceed 104°F
(40°C). If inadequately vented, the product’s service life, operation and reliability may be affected.
■Attaching rack mounting brackets
1. Remove four M5 screws from one side of the unit. Retain these screws for step 2.
2. Attach one bracket to the side of the unit using the screws removed in step 1.
3. Repeat steps 1 and 2 on the other side of the unit.
[Fig. 7.1] Attaching rack mounting brackets
Note:
The standard screw tightening torque is 2.94 N･m (about 30 kgf･cm).

7.2 Cabling
When connecting the MSD to external devices, please observe the following precautions.
・Read manuals for the external devices.
・Before you connecting cables to the MSD or an external device, dissipate static electricity by touching
grounded metal such as racks before handling signal cables. Failure to observe this precaution may
result in ESD (electrostatic discharge) damage.
・Power all units off before connecting cables.
・Be sure to fully seat all plugs and connections and dress cables to reduce stress on connectors.
・Secure HDMI cables using cable clamps to prevent connectors from being accidently pulled out of
ports.
