1 Introduction & Designated Use
The OTMC 100 is an antenna-integrated GPS controlled time reference. It provides high-precision
time to synchronize intelligent electronic devices (IEDs), computers and measurement equipment in
Ethernet (TCP/IP) based networks. The OTMC 100 series products can be used as a PTP (Precision
Time Protocol) grandmaster clock according to the IEEE 1588-2008 standard and as an NTP
(Network Time Protocol) time server for NTPv4 compliant equipment according to RFC 5905.
The fields of application for the OTMC 100 series products include applications in industrial production
involving automatic test equipment (ATE), time critical banking and telecom applications as well as
protection and control applications in the electrical power industry. The OTMC 100 is the right choice
wherever accurate time in a computer based network is needed.
Due to the unique combination of GPS antenna, GPS receiver and time signal processing, the
OTMC 100 can be directly connected to Ethernet networks without the need of additional RF cable
installation.
The OTMC 100 series is designed for outdoor use in lightning protected areas. It is intended for fixed
installation on masts. For installation requirements, please refer to the Quick Start Guide provided with
the product or chapter "Mounting" on page 14.
The following OTMC 100 models are available:
OTMC 100i: Time reference for use in industrial applications supporting the IEEE 1588-2008 default
profiles.
OTMC 100p: Time reference for use in the electrical power industry. In addition to the
IEEE 1588-2008 default profiles, the OTMC 100palso supports the power profile according to
IEEE C37.238-2011 (IEEE Profile for Use of IEEE 1588-2008 Precision Time Protocol in Power
System Applications) specifically used in the electrical power industry.
For reasons of simplicity this manual uses the general term "OTMC 100" if the features and
functionality described are common for all products of the OTMC 100 series. The complete names
OTMC 100iand OTMC 100pare only used to indicate differences between the models.
The unique design of the OTMC 100 series offers many advantages:
• Web browser interface (called Web Interface) allowing for intuitive and straight forward setup and
control. The use of DHCP/Auto IP and the OMICRON Device Browser tool allows for easy remote
access to all functions and features from a computer.
• Outstanding precision. Synchronized to the GPS satellite navigation system, the OTMC 100's
internal clock achieves a time accuracy of +/- 100 ns to reference time (UTC).
• No need for rack space in server rooms due to outdoor mounting.
• Extremely low power consumption < 2 W.
• Full compliance with IEEE 1588-2008 (IEEE 1588 version 2).
• Easy installation. No additional power supply required through PoE (Power over Ethernet).
Introduction & Designated Use

• Ethernet cable length up to 100 m (standard Ethernet). Can be increased to up to 2 km by using
fiber optic Ethernet and media converters.
• Automatic cable length compensation compensates errors due to propagation delays on the
network.
• Automated configuration. The possibility to upload configuration files enables easy exchange and
configuration of the hardware.
• The OTMC 100 enables redundant configurations as defined in IEEE 1588-2008. The best master
clock algorithm (BMCA) guarantees that the best clock in the system is used as the master clock.
An automatic changeover to another clock is performed if the active master clock no longer
provides sufficient time accuracy.
• Due to its integrated NTP server functionality the OTMC 100 can also be used in networks
containing devices that are not yet ready for PTP. The OTMC 100 is able to simultaneously operate
as NTP server and PTP grandmaster clock.
The following features are supported by the OTMC 100 software:

4 Mounting
4.1 Safety Instructions
A position with good view to the sky will usually be located in a lightning endangered zone outside of a
building. The OTMC 100 must not be exposed to direct lightning strokes and thus has to be protected
sufficiently. Therefore, the OTMC 100 has to be mounted in an area protected by a lightning protection
system according to the relevant standards and regulations. The user is responsible for sufficient
lightning protection of the device and the observance of all lightning protection regulations relevant for
the site of installation.
Always use the waterproof RJ45 Ethernet connector supplied with the OTMC 100 in order to maintain
the watertightness of the device. Do not use the OTMC 100 outdoors without a waterproof connector
inserted.
CAUTION! Risk of injury or damage due to high voltages caused by lightning stroke.
• The installation of the OTMC 100 and the implementation of lightning protection
measures have to be performed by accordingly qualified experts.
• Always observe all relevant lightning protection regulations.
• The local lightning protection regulations and the protection concept of the building and
the electrical installation may require a suitable surge protection device for the Ethernet
network cable leading into the building.
• For outdoor installation always use shielded Ethernet cable. The cable shield has to be
connected to the shield of the Ethernet connectors.
4.2 Suitable Mounting Positions
The OTMC 100 receives the time information from the satellites of the GPS system. However, GPS
reception generally requires a plain line of sight between the antenna and the satellites.
For proper function, the OTMC 100 requires signal reception from at least 4 GPS satellites. The more
satellites it can receive, the more reliable the time information the OTMC 100 can deliver.
The OTMC 100 should generally be mounted outdoors at a location that provides free view in a range
of 180° vertically to the sky and 360° horizontally around the device. The view to the sky must not be
blocked by any objects. This is usually given when mounting the OTMC 100 on a roof or a sufficiently
high mast. Refer to the figure below.
You should furthermore consider that GPS signals may be reflected by large buildings and structures
around the OTMC 100, which may deteriorate the timing accuracy of the OTMC 100.
Always mount the OTMC 100 in an upright position with the protective cap to the top, as shown in the
figure below. The RJ45 connector on the base plate of the OTMC 100 must point vertically
downwards. Do not mount the OTMC 100 inclined to any side or with the base plate to the top!

5 Connection, Access & Initial Setup
5.1 Connecting the OTMC 100 to an Ethernet Network
Note regarding network switches:
The precise synchronization of clocks via Ethernet networks requires that the propagation
delay times for data packets is constant on the entire network. Network switches that do not
provide transparent clock functionality may introduce jitter and thus influence the propagation
delay. Therefore, the OTMC 100 will only be able to provide highly accurate time
synchronization in networks that that are equipped with network switches providing
transparent clock functionality as specified in IEEE 1588-2008 or that do not have a network
switch at all.
Do not connect conventional RJ45 connectors that are equipped with a locking tab to the
OTMC 100! The locking tab of such connectors cannot be accessed directly anymore after
inserting the plug to the OTMC 100. In this case, a small screwdriver must be used to
carefully unlock the RJ45 connector in the socket. Use the waterproof RJ45 connector
supplied with the OTMC 100 instead or, when using a cable with a conventional RJ45
connector (for test purposes only!), break off the locking tab at the RJ45 connector before
inserting it to the OTMC 100.
The OTMC 100 is supplied with power by Power over Ethernet (PoE) according to IEEE 802.3af. If the
network port the OTMC 100 is connected to does not provide PoE, a PoE injector has to be used as
shown in the figure below.
The OTMC 100 supports Ethernet cable lengths of up to 100 m without the need of repeaters. By
using additional media converters the use of optical Ethernet is possible, which allows much longer
distances. Depending on the used variant it is possible to cover distances up to 2000 m. For further
details, please refer to the user manual of the media converters used.
The OTMC 100 automatically powers up after inserting the RJ45 plug and providing supply voltage to
the OTMC 100. After the device is supplied with voltage, the LED first lights up red for approx. 15 s
during the boot process and then changes to green to indicate operational readiness.
The OTMC 100 is a class 1 powered device (PD) as defined in IEEE 802.3af (power
consumption < 3.84 W). The network port the OTMC 100 is connected to must be able to
supply a class 1 powered device.
CAUTION! Risk of injury or damage due to high voltages caused by lightning stroke.
The local lightning protection regulations and the protection concept of the building and the
electrical installation may require a suitable surge protection device for the Ethernet network
cable leading into the building.
