Get Multiple Block Security Status
When receiving the Get Multiple Block Security Status command, the LRIS2K 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. In request, option flag must be set to
0.
Request parameters:
●
UID (optional)
●
First block number
●
Number of blocks
NOT set
Response parameters:
●
Block Locking Status (see Table 63: Block Locking status)
●
N blocks of data
