INSTALLATION
Content of the Box
The unit was packed carefully. Nevertheless we recommend to check the
content directly after opening the package:
1 x MC-5
1 x Power cable
1 x Manual
4 x Rubber feets
1 x Registration card
Placing the Device
The unit should be set up as closely as possible to the devices to which it
will be connected, so as to avoid excessive cable lengths. Use the 4 rubber
feets enclosed with the appliance and stick them symmetrically on the
bottom side of the unit to protect the enclosure and supporting surface
from being damaged. When the unit is installed in a rack, the rubber feets
cannot be attached to save space.
The device can be mounted into a standard 19“ rack and will require one
unit. For this installation MUTEC offers an optional set of rack ears (MW-
05/19, order no. 8020-035). The mounting depth including the terminals is
175mm/6.9“. Another 150mm/5.9“ should be added for the required cables.
Additional slide-in rails on the rack inside are recommended for safe instal-
lation. This will also avoid long-term mechanical deformation of the housing.
Wiring the Video Interfaces
To allow for the distribution of signals, the interfaces of all devices involved
must be properly connected to each other, so as to ensure a logical signal
flow. Always be sure to connect the video outputs of the MC-5 to the corre-
sponding inputs of the devices you wish to feed with the distributed video
signal. Cable lengths should be kept as short as possible to minimize signal
losses and/or interferences!
For the transmission of video signals electrical, unsymmetrical cables with a
resistance of 75 Ω and BNC connectors on both ends are used. Typically, such
cables are marked »RG-59U, RG59B/U«.
Additionally, you should make sure that the video inputs to be connected
to the MC-5’s outputs have a 75 Ω terminating resistor! Most video inputs
allow for enabling/disabling the termination with a so-called »termination-
switch«, which may be located on the outside or inside of the device.
For devices which have no termination of the video input, you can use an
additional BNC-T piece to terminate the input. Plug the T piece with its
center connector into the input of the receiving device. Then, connect the
cable coming from the MC-5 to one of the lateral connectors, and the other
connector of the BNC-T piece to a 75 Ω resistor forming the BNC termina-
tion.
Basically, you should avoid »looping through« video leads by means of
passive BNC-T pieces to preserve the signal quality, as level drops will be the
result. If there is no other way to wire your set-up, please make sure that all
video inputs (except for the last device in the chain) have their terminations
disabled! In a serial video chain only the last clock input should have a ter-
mination! Never connect more than three devices in series to one output!
Before installing the unit the section
SAFETY INSTRUCTIONS located
at the beginning of this manual
should be read carefully.
!
The condition of the packaging
material and the device should
be checked carefully additionally.
If there are any damages please refer to
SAFETY INSTRUCTIONS, Initial Operation,
and WARRANTY REGULATIONS.
!
Never expose the device and
accessories to rain, moisture,
direct sunlight, or excessive heat
produced by radiators, heaters, or spot
lights! Sufficient air circulation in the
environment of the device must be ensured!
!
It is imperative that the lengths
of all cables connected are largely
the same, as this is the only way to
ensure that all devices will be synchronized
or feeded in phase (exception: cable toler-
ances).
Please make sure that the cable used has a
resistance of 75 Ω, in compliance with the
specifications! If a cable with a different
resistance is used, a dramatic deterioration
of the signal quality can be the result! In
this case, the perfect synchronization or
feeding of all devices involved could be
impaired.
