INSTALLATION
Content of the Box
The unit was packed carefully. Nevertheless we recommend to check the
content directly after opening the package:
1 x iD / iDdp
1 x Power cable, 2 x power cables for iDdp
4 x Rubber feet
1 x Manual
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.
The device can be mounted into a standard 19" rack and will require 1
unit. In this case, the rubber feet cannot be attached. Install the device so
that one unit of rack space is left free both above and below the device to
allow for sufficient ventilation! The mounting depth including the termi-
nals is 240 mm/9.45" for iD and 280mm/11.02 for iDdp. Another 60 mm/2.4"
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 Word Clock Interfaces
To allow for synchronization 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 Word Clock outputs of iD to the accord-
ing inputs of the devices you wish to synchronize! Cable lengths should be
kept as short as possible to minimize signal losses and/or interference!
For the transmission of Word Clock signals electrical, asymmetrical cables
with a resistance of 75Ω and BNC connectors on both ends are used. Typi-
cally, such cables are marked »RG-59U, RG59B/U«.
Additionally, you should make sure that the Word Clock inputs to be
connected to iD's outputs have a 75 Ω terminating resistor! Most Word
Clock 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 Word Clock input, e.g. RME
Hammerfall with Word Clock i/o or Alesis BRC, you can use an additional
BNC-T piece to terminate the input. Plug the T piece with its center connec-
tor into the input of the receiving device. Then, connect the cable coming
from iD to one of the lateral connectors, and the other connector of the
BNC-T piece to a 75Ω resistor forming the BNC termination.
Basically, you should avoid »looping through« Word Clock 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 Word Clock inputs (except for the last device in the chain) have
their terminations disabled! In a serial Word Clock chain only the last clock
input should have a termination! Never connect more than three devices in
series to one output!

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.
Before installing the unit the section
!
SAFETY INSTRUCTIONS located
at the beginning of this manual
should be read carefully.
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
in phase (exception: cable tolerances).
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 of all
devices involved could be impaired.
We recommend using high-grade cables
with a good shielding for your clock signal
leads, in particular, if you need to transmit
Word Clock x 256 (so-called Super Clock)
signals over greater distances. In any case, a
length of max. 10 meters (approx. 30 feet)
should never be exceeded!
