For example:-
H1 type selected, MESSAGE command reply =
“ b IDE RWD H1 (SEC_COM V1.xx) DD/MM/YY) IB Technology accepts no liability for
the use of this product in any end application” 0x00
H2 type selected, MESSAGE command reply =
“ a IDE RWD H2 (SEC_COM V1.xx) DD/MM/YY) IB Technology accepts no liability for
the use of this product in any end application” 0x00
H400X/MC200 type selected, MESSAGE command reply =
“ c IDE RD H400X/MC200 (SEC_COM V1.xx) DD/MM/YY) IB Technology accepts no
liability for the use of this product in any end application” 0x00
Program EEPROM
The Micro RWD has some internal EEPROM for storing system parameters such as
passwords and authorised identity codes. This command sequence allows individual bytes of
the EEPROM to be programmed with new data. Note that due to the fundamental nature of
these system parameters, incorrect data may render the system temporarily inoperable.
