Setup
The following steps are to be carried out for the
initial installation of a digital microphone system
consisting of the microphone, the DMI-8 Digital
Microphone Interface and the RCS control soft-
ware.
First install the RCS and the associated drivers on
your computer.
The minimum computer requirements for operat-
ing the RCS control software are specified in the
RCS operating manual.
Start the setup program on the enclosed CD-ROM
(Windows: "Setup"; Mac OS: "Install RCS") and
follow the instructions displayed on the screen.
Attention:
• Administrator rights are required in order to
install the software.
• The USB 485 converter must not be connected
to a computer USB port until after the RCS soft-
ware has been installed.
USB driver installation
After the RCS has been installed, the USB 485
converter must be connected to the computer
USB port. This ensures loading of the supplied
USB driver, which is required for operation of the
converter.
Other connections
Connect the USB 485 converter to one of the RJ 45
ports (CTL BUS) of the DMI-8 by means of a patch
cable (not included).
Set the device address (ID) of the DMI-8 (by us-
ing the coding switch on the back of the DMI). Ad-
dresses should be assigned beginning with "0".
Attention: The ID is detected only during the
power-up process of the DMI-8. After the ID is
changed, the power supply must therefore be in-
terrupted briefly and then turned back on again.
Connect the microphone, the DMI-8 and the sub-
sequent device (e.g. a mixing console)
If the DMI and the connected microphones are to
be synchronized with an external synchronization
signal (a word clock or AES11 signal), use a BNC
cable to connect the sync signal to the word clock
input of the DMI-8.
If multiple DMIs are used, they are cascaded via
the control bus. For this purpose, use an RJ 45
patch cable to connect the second RJ 45 port of
the first DMI to one of the RJ 45 ports of the next
DMI, etc.
Since the DMIs must also be synchronized with
one another, connect the BNC output (word clock
or AES11) of each DMI to the BNC input of the sub-
sequent device.
Connect the DMI-8 to the power supply system
and start the RCS software.
Attention: The DMI-8 must be switched on before
the RCS is started so that the DMI-8 will be de-
tected by the PC or Mac. Alternatively, the com-
mand Options/DMI can be used to detect a DMI.
Due to USB interface specifications, in order to
prevent uncontrolled operation of the computer,
while the RCS is running, the cable connecting the
computer to the USB 485 converter must not be
disconnected.
Long microphone cables and multiple connectors
lead to a drop in the microphone supply voltage
and to an increase of jitter, particularly in the
case of high sampling rates. Therefore, if pos-
sible, use continuous cable between the micro-
phone and the DMI-8, and between the DMI-8 and
subsequent equipment. For longer distances use
AES/EBU cable exclusively (with an impedance of
110 ohms).
Ensure that the microphones and all devices in
the digital signal chain are synchronized. Micro-
phones connected to the DMI-8 must always be
operated in synchronous mode, whether or not
sample rate converters are used in the subse-
quent signal chain. The transmission of none syn-
chronized microphone signals is not supported by
the DMI-8.
Ensure correct fastening of the connectors when
connecting the cables.
Lay the cables in such a way that they do not pres-
ent a tripping hazard.
Updating of firmware
The firmware in the DMI-8 and in the Neumann
microphones is updatable. Updates can be per-
formed without opening the equipment, via the
RCS control software (see the RCS Operating
Manual).
