or by activating a weighing input;
the indicator then behaves as follows:
sends the data 3 times consecutively, if the indicator receives the ACK
character (06H) it waits for a new request;
If it receives the NAK character (15H) it retransmits the string because the
previous transmission failed;
After receiving the NAK character 3 times consecutively, the indicator inserts
the message "NO ACK" (transmission error) in the MF_error_LOG file
Remote commands, i.e. the dialogue between the devices takes place only
through specific commands transmitted by the external device (available only
in extended string format); to check which remote commands are available,
refer to the transmission manual
