REC. COMP.
The display unit is ready to receive a
compensation-value list (axis 1 or 2) over the
RS-232-C/V.24 interface. After successful
reception, return to the beginning
("TRANSFER") to transmit or receive more
lists. Continue in the data transfer menu with
the decimal point key. If
reqd.
or
Exit the data transfer function.
Note on the input/output of parameter and
compensation-value lists
With a terminal program (e.g. HyperTerminal, included with
Windows
® ), you can receive the lists output by the display
unit over the RS-232-C/V.24 interface as text files and save
them on your PC. Each list must be saved as a separate text
file. You can then use the terminal program to transmit the
text files back to the display unit .
If you wish, you can edit the text files with a text editor and
change the parameter values, for example. However, this
requires knowledge of the different output formats of the lists
(see following pages). When receiving lists, the display unit
expects the same list structure as used for the output.
When receiving lists, the display unit first waits for the starting
character < * >. The receiving mode ends as soon as the
display unit has received the final character < * >.
The lists received are first checked for the type of display unit
(line 2 of output list). The receiving display unit accepts only
lists prepared by the same type of display unit. Furthermore,
the list is checked for completeness. Lists that contain, for
example, too many or too few parameters are ignored. If an
error occurs, the following error message appears:
REC. ERROR
To clear the error message, press the CL key.
If the display unit receives invalid parameter values, it sets the
respective operating parameter to the default setting.
Example:
“P01 INCH = INCH = 3”
The value 3 is not allowed. The parameter P01 is set to the
default setting “P01 MM = MM = 0”.
