The drive software version consists of three numbers xx.yy.zz. Pr 11.29 displays xx.yy and zz is displayed in Pr 11.34. Where xx specifies a change
that affects hardware compatibility, yy specifies a change that affects product documentation, and zz specifies a change that does not affect the
product documentation.

This parameter is not used on Digitax ST and its value is fixed at 0.
11.36 SMARTCARD parameter data previously loaded
Bit SP

Range 0 to 999
Default 0
Update rate Background write
This parameter shows the number of the data block last parameter or difference from default data block transferred from a SMARTCARD to the drive.
11.37 SMARTCARD data number
Bit SP
Coding
Range 0 to 1003
Default 0
Update rate Background read
Data blocks are stored on a SMARTCARD with header information including a number to identify the block .The header information also includes the
type of data stored in the block (i.e. the file type), the drive mode if this is parameter or difference from default data, the version number and a
checksum. This data can be viewed through Pr 11.38 to Pr 11.40 by increasing or decreasing Pr 11.37. This parameter jumps between the data
numbers of the data blocks present on the card. If this parameter is increased above the highest data block on the card it can have the special values
given below:
1000 - shows the space left on the card for data blocks in 16 byte pages
1001 - shows the total space available on the card for data blocks in 16 byte pages
1002 - shows the state of the read-only (bit 0) and warning suppression flags (bit 1)
1003 - shows the product identifier
It should be noted that 16 bytes are reserved at the beginning and the end of the card that cannot be used to hold data. Therefore a 4096 byte card
has 4064 bytes (254 x 16 byte pages) available to hold data. Compatible cards from 4Kbytes to 512Kbytes may be used with the drive. The first 16
bytes on the card hold the card header information including the read-only flag, which can be set to make the whole card read-only, and the warning
suppression flag, which can be set to prevent C.rtg and C.Optn trips when data is transferred to the drive from a card. The card header also contains
the product identifier which is described later.
The actions of erasing a card, erasing a file, creating a new file, changing a menu 0 parameter, or inserting a new card will set Pr 11.37 to 0.
Various SMARTCARD actions can be initiated via Pr x.00 or the copying (Pr 11.42) and resetting the drive as given in the table below:
