Important safety precautions must be followed before attempting to
install, service, or maintain electrical equipment. Carefully read and
follow the safety precautions outlined below.
NOTE:
Electrical equipment should be serviced by qualied personnel. No responsibility is assumed by Cyber Sciences for any
consequences arising out of the use of this material. This document is not intended as an instruction manual for untrained
persons.
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
● Only qualied workers should install this equipment. Such work should be performed
only after reading this entire set of instructions.
● NEVER work alone.
●Before performing visual inspections, tests, or maintenance on this equipment, dis-
connect all sources of electric power. Assume that all circuits are live until they have
been completely de-energized, tested, and tagged. Pay particular attention to the
design of the power system. Consider all sources of power, including the possibility of
backfeeding.
●Apply appropriate personal protective equipment (PPE) and follow safe electrical prac-
tices. For example, in the USA, see NFPA 70E.
●Turn off all power supplying the equipment in which the device is to be installed before
installing and wiring the device.
● Always use a properly rated voltage sensing device to conrm that power is off.
●Beware of potential hazards, wear personal protective equipment, and carefully inspect
the work area for tools and objects that may have been left inside the equipment.
●The successful operation of this equipment depends upon proper handling, installation,
and operation. Neglecting fundamental installation requirements may lead to personal
injury as well as damage to electrical equipment or other property.
Failure to follow these instructions can result in death or serious injury.

The STR-100 Satellite Time Reference uses Global Positioning System
(GPS) technology to provide a highly-accurate date/time reference for
Sequence of Events Recording (SER) and other critical power appli-
cations. The STR-100 accepts an input from a Trimble Acutime 360
“smart antenna” or an amplitude-modulated (AM) IRIG-B source and
outputs a time reference signal accurate to +/- 50 microseconds using
standard time protocols: DCF77 and 1per10 (base model) or unmodu-
lated IRIG-B (model STR-100/IRIG-B). Up to 32 devices can be syn-
chronized from one STR-100.

Theory of Operation The STR-100 accepts a GPS time signal input from either a Trimble
Acutime 360 GPS smart antenna or from a GPS receiver with IRIG-B
output, and provides a time synchronization output in DCF77 or 1per10
format for multiple devices. Typical power distribution applications
include Sequence of Events Recording (SER) systems in data centers,
hospitals and re neries, and electric utility “Smart Grid” applications
such as Power SCADA and substation automation.
DCF77 is a time synchronization protocol used widely. The DCF77
time synchronization output is a 24Vdc pulse-width modulated signal
that provides a complete date/time string once a minute. The signal
contains a one-pulse-per-second component that is accurate to +/- 50
microseconds in reference to UTC (Coordinated Universal Time). The
pulse string contains a BCD (Binary Coded Decimal) value for minute,
hour, day, day of week, month, and year, as well as other control
parameters such as leap second and Daylight Saving Time.
1per10 is a simpler time protocol that uses one synchronizing pulse
every 10 seconds. Only channel 2 of the STR-100 time output can be
con gured for 1per10. The default output for both channels is DCF77.
On power-up, the STR determines the type of GPS data source, rst
checking for an Acutime antenna signal. If an antenna signal is not
detected, the STR checks for an IRIG-B signal. During the detection
test, the STAT (status) LED ashes twice repeatedly. Once a signal is
detected, the SYNC LED is turned on, and normal operation begins.
During normal operations, the SYNC LED remains lit, and the STAT
LED ashes repeatedly according to the type of receiver: three blinks
for IRIG-B, and four blinks for Acutime. The STR captures the date and
time each second, and outputs the DCF77 date and time at the top of
each minute.
Optional adjustments may be made for local time offset and Daylight
Saving Time (DST). The purpose of the local time offset is to convert
UTC time into local time, and its value depends on the user’s time
zone. If the user sets parameters for Daylight Saving Time, then the
STR makes this adjustment as well.

The STR-100 can be set on a at surface, mounted to a wall or panel
using screws, or DIN-rail mounted to a wall or panel using the DIN-rail
mounting kit provided. Figure 2-1 shows STR dimensions. Figures 2-2,
2-3 and 2-4 detail the various mounting options.
When choosing a mounting location, consider the following points:
●Allow for easy access to the STR-100.
●Allow space for all wires to be neatly routed down the side or
bottom of the device.
● Allow sufcient ventilation to avoid exceeding the operating
temperature limits of the device.
Typical locations for mounting the STR-100 include the following:
●Power equipment instrumentation compartment
● Ofce or raised-oor environment
●Auxiliary control panel or cabinet
