Rei Pro User Manual v.1.0.2
Page 14
The Rei Pro has a built-in GPS receiver. There is an icon next to the battery icon to show the satellite signal
reception status:
-
No icon if GPS is disabled;
-
White icon with an X if GPS is enabled but not linked to any satellites;
-
White icon with a signal if GPS is enabled and linked, but synchronization has not been enabled;
-
Green icon if GPS is enabled and linked, and the Rei Pro is synchronized;
-
Red icon if GPS is enabled but not linked, and the Rei Pro has lost synchronization.
You can decide whether to enable it or align with the official time.
There are two possible GPS synchronization methods:
2.1.4.1
One-time GPS synchronization
Once the Rei Pro has acquired the correct satellite signal, it synchronizes the time with the official time and
then relies on its internal quartz oscillator.
2.1.4.2
Continuous GPS synchronization
After aligning solar time with that of the GPS signal, the Rei Pro will continue to keep itself aligned. This
requires a continuous link with the satellite signal. The Rei Pro will remain synchronized with the GPS as long
as it receives the signal correctly. If the signal is lost, the timer will use its internal quartz oscillator. If the GPS
signal then returns, the Rei Pro will use it to realign the internal time if the difference is less than 300 µs.
When working in an enclosed space, use an external aerial connected to the dedicated port to receive the
GPS signal correctly.
You must set the time difference between your location and UTC:
2.1.4.3
Setting the UTC value
Coordinated Universal Time (UTC) is the reference time from which all other time zones are calculated.
UTC+0 refers to the time zone at the Greenwich meridian and, since daylight saving time is an invention
(which is not even used throughout the world), the UTC value does not consider it.
When solar time applies in Europe, the value will be UTC+1, and when daylight saving time applies, you should
set UTC+2.
Synchro output
You can set a time (HH:MM:SS) at which the Rei Pro will generate an output impulse on the digital port (Pin
6).
