Get Multiple Block Security Status
When receiving the Get Multiple Block Security Status command, the LRI2K sends back the
block security status. The blocks are numbered from '00 to '3F' in the request and the value
is minus one (–1) in the field. For example, a value of '06' in the "Number of blocks" field
requests to return the security status of 7 Blocks.
Request parameters:
●
UID (Optional)
●
First block number
●
Number of blocks
Response parameters:
●
Block Locking Status (see Table 61: Block Locking status)
●
N block of data
Response parameter:
●
Error code as Error_flag is set:
–
03h: Option not supported
–
0Fh: other error
