6.3
Data Strings
This Chapter describes the data strings supported by this System.
6.3.1 General Information about Data Output of Board 6844(RC)
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 pro-
gramming 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 6.1.2.5 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 selec-
tion of a data string in the Mode Byte.
Blocked:
Blocked settings are
not
permissible for a data string. The Sys-
tem does not accept such an input and the data string is transmit-
ted without an error message and with the previously set parame-
ters.
