5.9. Digital Inputs
Optionally, the Timeboy can be equipped with a connection cable and digital inputs. Please observe
the power requirements in the chapter "Technical Data".
The digital inputs can be used to save the state in a data record, to change power schemes, or to
achieve the state "vehicle drives".
For information on possible configurations see the manual "Datafox Studio".
5.10. GPS Receiver
The Timeboy can be equipped with a GPS receiver. It allows localization via satellite signals. The
GPS antenna is integrated in the Timeboy at the top of the casing above the display. Also an exter-
nal GPS module is available, which can be connected via the digital inputs. Thus, the GPS module
can be placed at a spot suitable for reception.
During GPS reception, very small signals received from various satellites must be processed. This
requires a certain amount of time, depending on different factors.
If you want to use GPS localization, please observe the following notices:
The Timeboy / antenna must have a clear view of the sky.
The reception is worse during bad weather conditions (clouds, rain, etc.).
The reception is worse in deep street canyons because often there is no unobstructed path to
the satellites and reflections may lead to distortions.
The worse the reception, the longer it takes until valid coordinates can be determined.
In houses, parking ramps and generally under roofs, often no reception is possible.
After valid coordinates have been determined, the receiver is more sensible. The initial determi-
nation of the coordinates requires a stronger signal.
So if your vehicle has a good GPS reception and drives under a roof, valid coordinates can still
be received. If the determination of coordinates must be restarted under a roof, it might not be
possible.
The GPS module consumes quite much current (ca. 30 mA at battery operation). The power
consumption is higher at no or bad reception (e.g. inside a building) than at good reception.
If the GPS module is turned off for more than 3 or 4 hours or is without reception, it has to be
restarted. It can take 3-5 minutes to determine valid coordinates. This has to be taken into ac-
count when the device switches to power saving mode. It is also important if the Timeboy often
has no reception and is used outside only for a short time.
For a description of possible settings see the manual "Datafox Studio".
