2 Introduction
This Setup Guide is a systematically structured guideline which supports you during the set-up of your Mein-
berg product.
The IMS-VSG181 is used as a video signal reference for studio equipment and provides the generated sig-
nals at four BNC outputs. These are 1x Bi-Level Sync (Black Burst)/Tri-Level-Sync, 1x Longitudinal Time and
Control Code (LTC), 1x Digital Audio Out (DARS), and 1x Word Clock
In order to be able to provide high-precision output signals during the switchover of the RSC (IMS systems
with redundant receivers), the IMS-VSG181 has its own oscillator.
Features.
The IMS-VSG181 is synchronized with an external reference frequency (10 MHz), a pulse per second (1PPS)
and a time telegram of the preconnected reference. These signals significantly determine the accuracy of the
output signals. All output signals can be configured extensively and individually via the web interface. The
generated signals have a phase reference to the 1PPS.
The LANTIME firmware manual provides a complete description of all configurations and status monitoring
options of your Meinberg product.

Compatibility
The IMS-VSG181 is an IMS module which is compatible with all systems of the IMS family. It can also
be used on any slot (MRI, ESI, I/O).

3 Important Safety Hints
Please make sure that IMS modules that can be exchanged during operation are always handled with utmost
care.
Before any maintenance work on the system:
•Backup of stored configurations is recommended (e.g. via USB stick or Web UI)
•Please note the chapter "Prevention of ESD damage".
•Please note the chapter "Supply voltage".

3 Important Safety Hints
3.2 Prevention of ESD Damage
ATTENTION!
The designation ESD (Electrostatic Sensitive Devices) refers to measures which are used
to protect electrostatically endangered components from electrostatic discharge and thus
to prevent destruction. Systems and assemblies with electrostatically endangered components
usually have the following characteristics:
Indicator for assemblies with electrostatic endangered components
The following measures protect electrostatically endangered components from destruction:
Prepare removal and installation of assemblies
Unload yourself (for example, by touching a grounded object) before touching assemblies.
Ensure that you wear a grounding strap on the wrist when working with such assemblies, which
you attach to an unpainted, non-conductive metal part of the system.
Use only tools and devices that are free from static electricity.
Transporting Assemblies
Assemblies may only be touched at the edge. Do not touch any pins or conductors on assemblies.
Installing and Removing Assemblies
Do not touch persons who are not grounded while removing or installing components. This could
result in a loss of grounding protection from your electrostatic discharge.
Storing Assemblies
Always keep assemblies in ESD protective covers. These protective covers must be undamaged.
ESD protective covers, which are extremely wrinkled or even have holes, no longer protect against
electrostatic discharge.
ESD protective covers must not be low-resistance and metallically conductive if a lithium battery
is installed on the assembly.

3.3 Supply Voltage
WARNING!
The IMS system in which the module is used operates at a dangerous voltage. The specific safety instruc-
tions can be found in the manual of the respective IMS System.
If the module is a hot-pluggable power supply unit, disconnect its power cable before removing it from the
IMS System.
Never open a power supply unit cause dangerous voltages can even exist after it has been disconnected from
the electrical supply. If a power supply is not working anymore, e.g. due to a defect, please send it back to
Meinberg for necessary repairs.
Non-observance of these safety instructions can cause serious personal injury and material damage. Installation,
initial start-up and operation of the IMS System may only be performed by qualified technical experts.
3.4 Cabling
WARNING!
Danger to life through electric shock! Never work with voltage applied! When working on the plugs and
terminals of connected cables, always disconnect both sides of the cables from the respective devices!

6 System Installation
6.1 Important Hints for hot-pluggable IMS Modules
The following points should be strictly observed when replacing IMS modules during operation. Not all IMS
modules are fully hot-pluggable. Of course, it is not possible to replace a power supply unit of a non-redundant
system without first having installed a second power source in operational mode.
The following applies to the individual IMS slots:
PWR: "hot swappable" If you operate your system with only one
power supply, a second power supply must
be installed before removing/replacing it
to keep your system functioning.
I/O, ESI and MRI Slots: "hot plugable".
CLK1, CLK2: "hot plugable" Afer the exchange or the installation of a
clock module a rescan of the reference clocks
(Rescan Refclocks) must be executed in the web
interface menu "System".
CPU: "hot plugable" The NTP service and access to the web interface
are interrupted while the CPU is disconnected.
Also the management and monitoring functions are
no longer available.
RSC/SPT: "hot plugable" The switching function or the distribution of
generated signals is interrupted while the RSC/SPT
is disconnected.

6 System Installation
6.2 Installation of hot-pluggable IMS modules.
If the system is supplied with an antenna and antenna cable, it is advisable to first mount the antenna in a
suitable location (see chapter Antenna Mounting) and lay the antenna cable.
Please use a Torx screwdriver (T8 x 60) for removal and installation of the module.
1. Follow the safety instructions at the beginning
of this manual!
2. Remove the two marked Torx screws from the
module holder plate or the cover plate of
the empty slot.
3. Note when removing!
Pull the module carefully out of the guide
rail. Note that the module is firmly anchored
in the connector block of the housing. You need
a certain amount of force to release the module
from this link. Once the connection to the
connector block of the system’s backplane is
loosened, the module can be easily pulled out.
4. Note during installation!
Please ensure that the module is correctly inserted into the
two guide rails of the system housing as otherwise damage to the module and the housing could be caused.
Make sure that the module is securely locked into the connector block before you fasten the two screws.
5. Now you can put the installed module into operation.
