Function Command Meaning
Checking of data MD-K By adding a check code to the Data Carrier’s data, it is possible to detect a data
error due to the battery of the Data Carrier that incorporates SRAM, or
excessive overwriting operations of the Data Carrier that incorporates
EEPROM. Use the MD-K command to calculate and write the check code to the
Data Carrier. Use the MD-C command to collate the check code. The MD-K
command and MD-C command must be always used together.
MD-C
Checking of the number
of overwriting operations MD-L Check the life of the Data Carrier’s EEPROM by counting the number of
overwriting operations. The Data Carrier’s EEPROM allows a total of 100,000
overwriting operations.
MD-S Use this command to specify the number of overwriting operations in the life of
the EEPROM in advance. Every time a write operation is performed, 1 is
subtracted and the Data Carrier will detect when the life has expired. This com-
mand is only available with models of lot number
@@ 55 (May 1995) or later.
