Preface & General Safety Instructions
This user manual provides information about the OTMC 100 series grandmaster clocks, their possible
fields of application and how to install and operate them. It furthermore provides information about
how to access and configure the devices using a computer.
Following the instructions given in this user manual will help you avoid danger, repair costs and down
time, and help maintain the reliability and life of the OTMC 100.
In addition to the user manual, the applicable safety and lightning protection regulations in the country
and at the site of operation as well as the usual technical procedures for safe and competent work
should be observed.
General safety instructions
Before operating the OTMC 100, carefully read the following general safety instructions:
• The OTMC 100 may only be used in a safe technical condition taking into account its defined
purpose, safety requirements and possible risks as well as the operating instructions given in this
user manual!
• The OTMC 100 is exclusively intended for the application areas specified in chapter "Introduction
and Designated Use" on page 7. The manufacturer or the distributors are not liable for damage
resulting from unintended usage. The user alone assumes all responsibility and risks.
• Do not open the OTMC 100! Opening the device invalidates all warranty claims!
• The OTMC 100 is an SELV device (Safety Extra Low Voltage) which is supplied with power by
Power over Ethernet (PoE according to IEEE 802.3af). It may only be connected to Ethernet
network ports or Power over Ethernet power supplies.
• 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.
• For outdoor installation always use shielded Ethernet cable. The cable shield has to be connected
to the shield of the Ethernet connectors.

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:
• Time:
• IEEE 1588-2008 version 2 support:
Default E2E (end-to-end) and P2P (peer-to-peer) profile
Power profile acc. to IEEE C37.238-2011 (OTMC 100ponly)
One step and two step operation
Multicast transport
IPv4, IPv6 and layer 2
PTP management interface
High performance (up to 512 messages per second)
• NTPv4 (according to RFC 5905)
• Time (according to RFC 868)
• Daytime (according to RFC 867)
• Networking:
• 10Base-T/100Base-TX Ethernet
• IPv4 and IPv6
• DHCP/Autoconf
• Zeroconf (mDNS/DNS-SD)
• OMICRON OMFind service

• Linux operating system:
• TFTP, FTP and SSH access
• Syslog (local and remote)
• E-Mail notification
• Configuration:
• Web Interface (HTTP & HTTPS)
• Automated configuration via SSH and XML files
• SNMP (for IEEE C37.238-2011)
• Failsafe software upgrades in the field
OTMC 100 series products are exclusively intended for the applications stated in this chapter. Any
other use is considered improper.
