Interfaces
An interface should be considered as
a function of the sensor. For example,
Real-Time is one function that can be
activated on the sensor, Hidden Point
is another function and so on.
System 500 supports the following
interfaces:
Real - Time Input/Output
NMEA Output
ASCII Input
Hidden Point Input
Meteo
Tilt
GSI/ User Out
Remote Control
PPS Output
Event Input
Each interface may be controlled by
one or more Devices.
For further details on the interfaces
Tilt and Meteo see App. J.
Devices
A device should be considered as
both the hardware which is used in
connection with an interface and the
parameters that allow the hardware to
communicate with the sensor.
The devices that are supported by the
sensor can be divided into the follow-
ing groups:
RS232
Radio modem devices
GSM
Modem devices
RTB Module (CSI)
RTS Module (Racal)
SAPOS
Hidden Point devices
Certain devices may be used with
one or more interfaces. For example,
a radio modem can be used to
receive Real-Time Reference data
but a second radio modem could also
be used to simultaneously output
NMEA messages.
Note:
The PPS Output and the Event Input
are optional interfaces that require
special hardware (ports) and devices
which are not described here. Please
refer to the respective chapters in
section 9 of this manual.
