6. Operation and function description
All values are written directly into the
EEPROM
of the unit and are valid after changing into
operating mode. In contrast, the communication parameters of the interface only become
effective after restarting the display.
To simplify the input, there is no need for "." (dots) and "," (commas).
In the basic setting, a message is not acknowledged, which enables the parallel programming of
several displays. To check the overall configuration, a checksum can be called up on the LED
display.
Successful programming is indicated by a "PROG“ in the LED display.
If you want to call up the content of a program number (e.g. 61), you can do so with the
command
"61
¥
"
The display sends the corresponding value back in ASCII format.
e.g. "5000
¥
"
Should a program number also contain subsidiary parameters – like the corresponding binary
value in case of a calibration point – it can be called up via the extension "B".
e.g.
"1B3433
¥
"
If the scaled value needs to be changed, the extension "=" is used.
e.g.
"1=12000
¥
"
Any entry that cannot be interpreted is acknowledged with an "
Err
" in the display.
If a non-existent program number or an unknown command is sent, the display will acknowledge
this with an "
?
" via the interface.
Under normal conditions, the display does not send an acknowledgement back. Only when the
value is called up or the acknowledgement mode is activated by the “>“ command, the display
sends a response from then on. This mode is exited after restarting the unit or 15 seconds after
receiving the last command.
Serial special commands
In addition to the program number control, special commands are also possible. In the following
table we have dispensed with giving the
¥
at the end of the command.
