3 Introduction
3 Introduction
This Setup Guide is a systematically structured guideline to assist you with the initial set-up of your Meinberg
product.
The IMS-TCR180 receiver module is used to decode and generate modulated (AM) and unmodulated (DC
level-shift) IRIG-A / B / G, AFNOR, C37.118, and IEEE1344-formatted time codes. Time codes are transmitted
by modulating the amplitude of a sinusoidal carrier wave, while unmodulated codes are transferred by modu-
lating the pulse width of a TTL signal.
As standard, the TCR180 clock module is equipped with an OCXO-SQ (Oven-Controlled Xtal Oscillator) which
serves as the master oscillator to ensure high accuracy of ±1x10-8 during holdover mode. An optional OCXO-
MQ or OCXO-HQ oscillator is available for higher accuracy.
Functionality:
The automatic gain control within the modulated code receiver circuit allows IRIG-A / B / G, AFNOR, C37.118,
or IEEE1344 signals to be decoded with a carrier amplitude of 600 mVpp to 8 Vpp.
The input stage is electrically isolated and has an impedance of either 50 Ω, 600 Ω(default) or 5 kΩ, se-
lectable using a jumper (see chapter "Adjusting Input Impedance") on the board.
The DC level-shift input is electrically isolated using an optocoupler with an internal series resistance of 220 Ω.
Features
•IRIG Generator
•4 Programmable Pulse Outputs

4 Important Safety Information
4 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, Meinberg recommends:
•backing up stored configurations (e.g., via USB flash drive or Web UI)
•taking note of the chapter "Prevention of ESD damage".
•Please note the chapter "Supply voltage".

4.2 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 and malfunction.
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.

4 Important Safety Information
4.3 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.
4.4 Handling of Batteries
WARNING!
The lithium battery on the receiver modules has a life of at least ten years. Should it be necessary to replace
it, please note the following:
Improper handling of the battery can lead to an explosion or to a leakage of flammable liquids or gases.
•Never short-circuit the battery.
•Never attempt to recharge the battery.
•Never throw the battery into a fire.
•The battery must only be exposed to the barometric pressure range specified by the battery manufacturer.
•The battery must only ever be replaced with one of the same type or a comparable type recommended by
the manufacturer. The battery must only be replaced by the manufacturer or an authorized technician.

6.3 Adjusting Input Impedance
Time code specifications do not specify values for modulated codes, neither in relation to the output impedance
of the transmitter, nor to the input impedance of the time code receiver.
This has resulted in time code component manufacturers selecting arbitrary values, which in turn means that
not all devices are compatible with one another. For example, if the time code generator has a large output
impedance and the time code receiver has a low input impedance, the signal level at the receiver input may be
too low to read. This is why the IMS-TCR180 has been equipped with an input impedance jumper, which can
be used to adjust the module to a variety of systems and can be set to one of three impedance values: 50 Ω,
600 Ωoder 5 kΩ.
The image below shows the various possible jumper positions with the corresponding input impedance val-
ues:
Jumper right
600 Ohm
Jumper left
50 Ohm
No jumper
5 kOhm
Note: The IMS-TCR180 is shipped with the jumper set to 600 Ω.

7.1 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.
IMS-TCR180 Date: December 17, 2021 15

7.2 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.

7 System Installation
7.3 Use of Coaxial Cable as Signal Conductor
The TCR180 module provides two BNC connectors for providing time code signals to synchronize the system.
Your system must be connected to the TCR180 signal inputs using coaxial cable with the proper character-
istic impedance and adequate shielding.
A mismatched cable impedance will result in signal distortion, while poor shielding can cause signal inter-
ference.
