Parameters
Details
#
= number to be
assigned to the field
Accepted values: 0 to 9999
Default value: 0
b
= starting block
number
Accepted values: 0 to n, where n is the maximum number of
blocks for the tag.
blocks for the tag.
Default value: 0
n
= number of
blocks/bytes to read
For R4Mplus printers with firmware version SP994X
(European version):
This parameter applies only when the starting block number
(parameter b) is 1.
(European version):

bytes for the tag. For UCODE EPC 1.19, n is 32.
Default value: 1
For all other supported printers:
Accepted values: 1 to n, where n is the maximum number of
blocks for the tag type minus the starting block number. For
example, if the tag has 8 blocks (starting with block 0) and
you start with block 6, n can be 2. This would return block 6
and block 7 information.
