Precautions
Important Safety Warnings
[Power]
Caution
Operate unit only at the specified supply voltage.
Disconnect the power cord via the power plug only. Do not pull on the cable portion.
Stop
Do not place or drop heavy or sharp-edged objects on the power cord. A damaged
cord can cause fire or electrical shock hazards. Regularly check the power cord for
excessive wear or damage to avoid possible fire / electrical hazards.
Caution
Ensure the power cord is firmly plugged into the AC outlet.
[Operation]
Hazard
Do not operate the unit under hazardous or potentially explosive atmospheric
conditions. Doing so could result in fire, explosion, or other hazardous results.
Hazard
Do not allow liquids,metal pieces, or other foreign materials to enter the unit. Doing
so could result in fire, other hazards, or a unit malfunction.
If a foreign material does enter the unit, turn the power off and immediately
disconnect the power cord. Remove the material and contact an authorized service
representative if damage has occurred.
[Transportation]
Caution
Handle with care to avoid impact shock during transit, which may cause
malfunction. When you need to transport the unit, use the original or suitable
alternative packing material.
[Circuitry Access]
Do not remove covers, panels, casing, or access circuitry with power applied to the
unit! Turn power off and disconnect power cord prior to removal. Internal servicing /
adjustment of unit should only be performed by qualified personnel.
Do not touch any parts / circuitry with a high heat factor.
Capacitors can retain enough electric charge to cause mild to serious shock, even
after power is disconnected. Capacitors associated with the power supply are
especially hazardous. Avoid contact with any capacitors.
Unit should not be operated or stored with cover, panels, and / or casing removed.
Operating unit with circuitry exposed could result in electric shock / fire hazards or
unit malfunction.

[Potential Hazards]
If abnormal smells or noises are noticed coming from the unit, turn power off
immediately and disconnect power cord to avoid potentially hazardous conditions. If
problems similar to above occur, contact authorized service representative before
attempting to again operate unit.
[Rack Mount Brackets and Rubber Feet]
To rack mount or to install rubber feet, do not use screws or materials other than
those supplied. Otherwise, it may cause damage to the internal circuits or
components of the unit. If you remove the rubber feet attached on the unit, do not
reinsert the screws securing the rubber feet.
[Consumables]
The consumables used in unit must be replaced periodically. For further details on
which parts are consumables and when they should be replaced, refer to the
specifications at the end of the Operation Manual. Since the service life of the
consumables varies greatly depending on the environment in which they are used,
they should be replaced at an early date. For details on replacing the consumables,
contact your dealer.

1-2. About the MV-42HS
The MV-42HS Multi Viewer is a 4-channel multi viewer that resizes and displays up to 4 inputs of
HD-SDI, SD-SDI, and analog composite* signals on a single screen. Audio level metering of SDI
embedded audio signals is provided allowing audio signal presence to be monitored. Remote
controls via GPI and LAN are also supported by the MV-42IF/IFA option.
The MV-42HS is most suitable for monitoring systems with mixed HD-SDI, SD-SDI, and analog
composite input signals.
* Analog composite input is supported by the MV-42AI option.
➢Support for mixed input of HD-SDI, SD-SDI, and analog composite (with the MV-42AI option
installed) signals (Mixed and asynchronous input supported)
➢Audio level metering for HD/SD-SDI embedded audio signals (Up to 8ch display)
➢HD-SDI and DVI-D (1920x1080 or 1280x720) high definition image output
➢Video loss detection
➢Display of ancillary time code (ATC) embedded on HD/SD-SDI input signals
➢Title display of up to 16 characters for each input (alphanumeric and symbol)
➢Remote control and title settings via RS-232C and LAN* interfaces (* with the MV-42IF/IFA
option installed)
➢Remote control and tally inputs via GPI (with the MV-42IF/IFA option installed)
➢Tally border display around windows via RS-232C/LAN/GPI
➢Date/Time display (with the MV-42IF/IFA option installed)
➢External reference signal and HD-SDI/DVI-D output genlock function (with the MV-42IF/IFA
option installed)

2. Connection
This chapter describes the procedure for setting up a basic system for the MV-42HS multi viewer.
IMPORTANT
Use SDI and DVI monitors that support 1920 x 1080 (59.94 or 50) interlaced and/or
1280 x 720 (59.94 or 50) progressive video signals.
2-1. Basic Connections
1) Apply DC power to the MV-42HS using an AC adapter.
2) Connect signal source devices, such as video cameras, to the HD/SD-SDI IN connectors.
3) Connect an SDI or DVI monitor.
2-2. Connection with MV-42AI and MV-42/IF / IFA Options
Installed
1) Apply DC power to the MV-42HS using an AC adapter.
2) Connect signal source devices, such as video cameras, to the HD/SD-SDI IN and/or
ANALOG COMPOSITE IN connectors.
3) Connect an SDI or DVI monitor.
4) Connect LAN connectors of the MV-42HS and a PC to be used for remote control using a
LAN cable.
* Use a crossoverLAN cable when directly connecting the MV-42HS to a PC. Use a straight
LAN cable when connecting the MV-42HS and PC using a hub.
5) Input a BB or tri-level sync signal.
6) Input a time code to be used for Time display.
