1. DESCRIPTION
1.1 Introduction
RT434 - GPS Grandmaster Clock is a clock referenced to GPS satellites, whose main application is to be a source
of temporal synchronization signals in different formats and protocols to synchronize internal clocks of equipment
and systems based on digital processing.
It has high accuracy (100 ns) and signal stability, even in situations where there is loss of GPS satellites. Provides
temporal synchronization for applications as synchrophasor measurement, traveling wave fault location, and other
applications.
The timing information presented on the front display of the RT434 can be referenced local or UTC time and can
be modified by the DST rules defined by the user.
It supports the following protocols sync time:
PTP (Precision Time Protocol) according to IEEE1588 standard, eliminating delay from message processing
which pass in other devices in the network;
NTP/SNTP;
IRIG-B004 (Demodulated);
IRIG-B124 (Modulated);
DCF77;
Serial Datagrams through the RS232 and RS422/485 serial ports.
This User Manual is structured as follows:
Chapter 01 presents the description of the RT434, its applications, technical characteristics and presentation of the
manual.
Chapter 02 shows how the RT434 should be installed considering the power, cable connection, sync outputs, etc.
Chapter 03 shows the communication mechanisms to access monitoring and configuration interfaces of the RT434.
Chapter 04 describes how the RT434 should be configured according to the options parameter of timing sources
and network parameters.

Chapter 05 shows how to operate the RT434, describing the local interface access and status indicators for
operation and remote monitoring.
Chapter 06 describes concepts and procedures to maintain the RT434.
Appendix A presents the format of the signals that compose the standard IRIG-B timing.
Appendix B presents the concepts of standard PTP synchronization (IEEE1588).
Appendix C presents the format of the synchronization signals based on Serial datagrams.
Appendix D presents the considerations used by RT434 to compensate delays inserted by the cable length of the
GPS antenna.
Appendix E gives some architectures implementing the RT434 as a source of timing for different electronic devices.
