6.1.1. GPS
Set whether the time and date are to be sent as separate objects or as one common
object. Specify whether the time and date are to be set by the GPS signal or objects.
If time and date are
set by the GPS-Signal
, the data is available as soon as a valid
GPS signal is received.
If time and date are
set by two objects
, then only a maximum of 10 seconds may
elapse between receiving the date and receiving the time Furthermore, a change of
date may not occur between receiving both objects. The objects must be received by
the device on the same day.
The device has an integrated real-time clock. Therefore, time keeps on running inter-
nally and can be sent to the bus, even when no GPS coverage is available or no time
object has been received for some time. The internal clock can show a time drift of up
to ±6 seconds per day.
Set what happens in the event of a GPS malfunction. Please note, that after return of
auxiliary voltage, it can take up to 10 minutes before the GPS signal is received.
6.2.
Location
The location data is required in order to be able to calculate the
position of the sun
with the help of the date and time.
The
location
is received via GPS or entered manually (selection of the nearest town
or by entering coordinates). Also when using the GPS signal coordinates can be en-
tered manually for the initial commissioning. This data is used as long as no GPS re-
