3 Modular System IMS-MDU
3 Modular System IMS-MDU
Meinberg MDU (Multi-Distribution Units) are the simplest and most convenient way to add more buffered
timing signal outputs to your distribution rack. MDU systems enable multiplication of input signals coming
from an external system such as a LANTIME or a GPS clock with, for example, PPS and 10MHz outputs to
be expanded to a large number of output signals of the same type. The 3U / 19-inch MDU basic chassis can
compose of a redundant power supply and can be equipped with one or two input modules to allow redundancy
of the input signals.
An MDU Input Module (SDI - Signal Distribution Input) can provide up to four inputs via BNC or SMA
connectors - with 10 MHz, PPS, TC-AM and TC-DCLS as input signals. An optional alarm relay contact and
status LEDs on the front panel show the user whether an input signal, an internal error (in case of a SDI-2101)
or an error of the upstream clock (SDI-4112) which can affect output signals has been detected. With a SDI-
2101 module, an internal error or a status of the card can be transferred via USB interface.
The IMS-MDU System can be configured with up to 14 Output Signal Modules, each including 4 BNC female
connectors (other connector types are available upon request).
For IMS-MDU Systems the following plug-in modules are available divided into below-mentioned categories:
•PWR (Power Supply)
•SDI (Signal Input Modules)
•SCU (Switchover unit for Redundant operation)
•I/O (Output modules)
PWR:
Two PWR slots - they can be equipped with various IMS power supply modules in AC / DC range 100-240 V
or low DC 20-72 V. In this way a basic or redundant power supply configuration can be realized.
SDI:
Two slots for SDI Input Signal modules. They have a dual function. By default, they can be attached with
two separate systems using different input cards individually or duplicated input signals to facilitate redundant
operation. It is also possible to plug a Standard Meinberg Receiver into SDI slots. In this case the receiver
generates output signals independently.
SCU:
In redundant operation a RSC (Redundant Switch Controller) card switches to serial interfaces and pulse /
frequency outputs of the redundant input card in case of a failure of the active input module. The switching can
be perfomed manually or automaticaly. All essential functions of the RSC, such as the actual switching status,
alarming and operation mode can be monitored or triggered via a SNMP / Ethernet Interface.
I/O:
Up to 14 output modules can be inserted for individual configuration of the IMS-MDU system.

4 Quick Start Guide for Initial Operation
After a power cable has been connected to the IMS MDU and the RSC switch card has been connected to the
network, the installed IMS modules can be configured and monitored by using the software Meinberg Device
Manager.
The Meinberg Device Manager software can be downloaded here:
Windows: https://www.meinbergglobal.com/download/utils/windows/mbgdevman_setup.exe
Linux: https://www.meinbergglobal.com/download/utils/linux/mbgdevman.tar.gz
Configuration via network with Meinberg Device Manager
After starting "mbgdevman" , all devices found in the network will be shown in the main window. By clicking
the plus button on the left side of an MDU entry, all installed IMS modules can be displayed. The LED icon
indicates the status of the module. After selecting the checkbox, the buttons "Edit Connection Settings" and
"Remove Device" are activated in the top left of the window. You can now use the "Edit Connection Settings"
button to adjust the connection type (network or serial connection). Here, you can also change the password,
that shall be used to connect to a network device (default: "mbg").
The upper part (center) of the window also contains the buttons "Configure Device(s)" and "Show Device(s)
Status". The button "Configure Device(s)" opens the "Device Configuration" window, where all important settings
for the selected module(s) can be made:

The figure shows the network status and the module sensors (temperature, voltage ...).
Network Settings
To adjust the network parameters of the MDU-RSC,
you can open the "Device Configuration" window and
select "Network" from the drop-down list at the top.
By default, the DHCP service is enabled so that an IP
address is assigned automatically. If no DHCP server
could be found or no IP address has been assigned
via DHCP by any other reason, a fallback IP address
169.254.xxx.yyy will be set automatically (Zeroconf 1).
If a static IP address shall be assigned, DHCP has
to be disabled in this area.
1Zeroconf: If a computer configures a link local IP address, it selects an IP address between 169.254.1.0 and 169.254.254.255 by using a
random number generator.

5.3.3 SDI-N2X - Signal Input Module
•Configuration and montoring with MBGDEVMAN
•PTP Multicast (Power Profile compatible / PTP Unicast (Telecom Profile compatible) / NTP)
•PPO (PPS, PPM, PPH ...),
•IRIG AM, Freq. Synth. sinus outputs
•Generates several different unmodulated IRIG time codes
The Meinberg N2X180 is synchronized by an PTP Grandmaster or by a NTP Server and can be used as
reference time source for the IMS MDU. The module provides equipment that requires Freq.Synth/sine, PPOs
(PPS, PPM, PPH, Time Code DCLS - IRIG/AFNOR/IEEE1344) or serial time string for synchronization.
The N2X180 operates as an IEEE-1588 slave clock or NTP client in a network.
This converter can synchronize many different systems. Our IEEE-1588 Grandmaster or LANTIME NTP Server,
such the LANTIME M1000, can be used as a reliable time source.
In order to support network management systems the N2X180 offers an extensive SNMP Interface, which
can be accessed by SNMP V1.
