· N° 1 digit for check-digit
4.9 M-FISC: Reading and Printing Fiscal Memory
This option is enabled only if an optional memory thanks to which each weigh is stored in non-
volatile memory accessible only upon explicit request.
The capacity of this memory allows you to store up to 160000 weighed.
4.9.1 REG-F Reading Memory Register
By setting the address of the desired location, (0 to 960000) will display the weight data it
contains.
If the lease is still empty the message "NOCODE" And if there are a weighted value is
displayed alternately weight saved on the record date.

ON REQUEST COMMUNICATION PROTOCOL
These are the structures of a request from host to SW22 :
structure 1
ADDR CMD EOT
structure 2
ADDR CMD PARAM ETX CHK EOT
where:
ADDR start transmission character : STX (02 Hex) when the
address of SW22 is 0 ; when the address is not 0 it is the
sum between character 80 Hex and the value of the
address.
CMD sequence of characters that identify the operation
requested to SW22.
PARAM sequence of characters that gives to SW22 the necessary
information for the execution of an operation.
ETX end character ETX ( 03 Hex ).
CHK checksum value used by SW22 to verify the correct
reception ; this value is the operation XOR between
characters ADDR and ETX.
EOT end transmission character EOT ( 04 Hex ).
