5.3 Data Strings
This Chapter describes the data strings supported by this System.
5.3.1 General Information about Data Output of Board 6842 GPS
When "last control character at second change" is set there is a transmission gap of up to
970msec., depending on the baud rate. This should be taken into consideration when
programming the time-out on the reception side.
The output of control characters CR and LF can be reversed with
Mode Byte 1
on all data
strings
(see
chapter 5.1.2.5 Mode Byte 1 / Bit 3 - Reverse Control Characters CR and LF
).
Possible string-specific settings are specified for all data strings.
These are differentiated as follows:
Automatic:
Automatic string settings are set “automatically“ by the System
immediately after the selection of a data string. Customer settings
are not required.
Required:
Required string settings must be set by the customer after
selection of a data string in the mode byte.
Blocked:
Blocked settings are
not
permissible for a data string. The
System does not accept such an input and the data string is
transmitted without an error message and with the previously set
parameters.
The transmitted data strings are at present compatible with the data strings of the following
