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 Information
3 Important Safety Information
Please ensure that IMS modules designed for "hot-plugging" (modules that are removable and insertable while
a system is in operation) are always handled with the utmost care.
Before performing any maintenance work on the system:
•We recommend making a backup of any stored configurations (e.g. using a USB flash drive or from the
Web UI)
•Take note of the chapter "Prevention of ESD Damage".
•Take note of the chapter "Power Supply".
3.1 Additional Safety Information
This manual contains important safety information regarding the installation and use of the device. Please read
it through fully before setting up the device for use.
This device may only be used for the purpose described in this manual. In particular, the specified operat-
ing limits of the device must be heeded. The person setting up the device is responsible for safety matters in
relation to any larger system in which the device is installed!
Failure to observe these instructions may have an adverse impact on device safety!
Please keep this manual in a safe and accessible place.
Target Readership
This manual is only intended to be used by qualified electricians, or by persons who have been appropriately
instructed by qualified electricians and who are familiar with applicable national standards and safety rules &
regulations, especially in relation to the installation of low-voltage (< 1000 V) installations.

3.2 Prevention of ESD Damage
ATTENTION!
An ESDS device (electrostatic discharge-sensitive device) is any device at risk of damage or
malfunction due to electrostatic discharges (ESD) and thus requires special measures to prevent
such damage or malfunction. Systems and modules with ESDS devices usually bear the following
symbol:
Symbol Indicating Devices with ESDS Components
The following measures will help to protect ESDS components from damage, malfunction and
destruction.
When preparing to dismantle or install devices:
Ground your body (for example, by touching a grounded object) before touching sensitive devices.
Ensure that you wear a grounding strap on your wrist when handling such devices. These straps must
in turn be attached to an uncoated, non-conductive metal part of the system.
Use only tools and devices that are free of static electricity.
When transporting devices:
Devices must only be touched or held by the edges. Never touch any pins or conductors on the device.
When dismantling or installing devices:
Avoid coming into contact with persons who are not grounded. Such contact may compromise your
connection with the earth conductor and thus also compromise the device’s protection from any
static charges you may be carrying.
When storing devices:
Always store devices in ESD-proof ("antistatic") bags. These bags must not be damaged in any way.
ESD-proof bags that are crumpled or have holes cannot provide effective protection against
electrostatic discharges.
ESD-proof bags must have a sufficient electrical resistance and must not be made of conductive
metals if the device has a lithium battery fitted on it.

3 Important Safety Information
3.3 Power Supply
WARNING!
The IMS system in which the module is used is operated at a dangerous voltage. Please refer to your IMS
Manual for more information about safety.
When removing a hot-pluggable power supply unit, always disconnect its power cable before removing it from
the IMS system.
Never open a power supply unit—there may still be hazardous residual voltages present even after disconnec-
tion from the mains supply. In the event that a power supply unit is no longer working (e.g. defective), please
return it to Meinberg for repair.
Failure to observe these safety instructions may result in serious injury and/or property damage. The IMS
system must only be installed, set up and operated by qualified personnel.
3.4 Cabling
WARNING!
Danger of death from electric shock! Never work on the system while the power is live! Always disconnect the
cables from the devices at both ends before working on the plugs and terminals of connected cables!

6 System Installation
6.1 Important Information Regarding Hot-Pluggable IMS Modules
The following information should be strictly observed when replacing IMS modules during operation. Not all
IMS modules are fully hot-pluggable. For example, it is naturally not possible to replace a power supply unit in
a system without PSU redundancy without first having installed a second power supply unit while the system
is in operation.
The following rules apply for the individual IMS slots:
PWR Slot: "Hot-Swappable" If you operate your system with only one power supply unit,
a second power supply unit must be installed before removing
or replacing it in order to keep your system on.
I/O, ESI and
MRI Slots: "Hot-Pluggable".
CLK1/CLK2 "Hot-Pluggable" When a clock module is replaced or installed, it is important to rescan
Slots: the reference clocks ("Rescan Refclocks") in the "System" menu
of the Web Interface.
RSC/SPT Slots: "Hot-Pluggable" It will not be possible for your IMS system to switch between signal
generators while the RSC/SPT is not installed.
——————————————————————————————————————————————
CPU Slot: "Not Hot-Pluggable" Before the CPU is removed, the IMS system must be powered down.
Please note that after powering on and rebooting the LANTIME
Operating System, the configuration of some IMS modules may be reset
to factory defaults!
The NTP service and access to the web interface will be unavailable while the CPU
is not installed. Management and monitoring functions will also be disabled.

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 (refer to the chapter "Mounting the Antenna" in your IMS system manual) and to lay the
antenna cable.
Please use a Torx screwdriver (T8 x 60) to remove and install IMS modules.
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. Please note when removing modules:
The module must be pulled carefully out of the
guide rail. Note that the module will be
securely seated in the connector block inside
the chassis. A certain amount of force must
be applied to release the module. Once the
module has been detached from the connector
block in the system backplane, the module can
be easily pulled out.
4. Please note when installing modules:
Ensure that the module is correctly inserted into the two guide rails of the system chassis. Failure
to do so may result in damage to the module and chassis. Ensure that the module is securely seated
in the connector block inside the chassis before you fasten the two screws.
5. The installed module is now ready for use.
