Operation
Parameter 32
(0x20)
ShowTagType
The transponder type can also be displayed. For this purpose, a number for the
transponder type is displayed in front of the actual transponder data. This
behavior can be activated or deactivated.
Values:
on - transponder type is displayed
off - transponder type is not displayed
Default: off
The transponder types are displayed by the following values:
01 - Read Only Transponder
02 - Read/Write Transponder
03 - Multipage Transponder
Parameter 33
(0x21)
ReadPage
This parameter determines the start position of a read operation on a multipage
transponder.
Values:
0x01 .. 0x11 - page 1 to 17
Default: 0x01 (standard value for scanning)
When the value is 0, the different transponder types are read as follows:
Multipage transponder - only page 1 is read (8 bytes)
Read Only - entire transponder is read (8 bytes)
Read/Write - entire transponder is read (8 bytes)
The transponder types Read Only and Read/Write can only be read when the
value is 0.
Parameter 34
(0x22)
ReadLength
This parameter defines the length of the data (intervals of 8 bytes) that are to be
read during a read operation.
The displayed value adjusts to the value of the parameter ReadPage. This means
that if the read operation starts from page 1, a maximum of 136 (= 17 pages x 8)
bytes can be read. However, if the read operation starts from page 2, then a
maximum of only 128 (16 pages x 8) bytes can be read.
Values:
0x08…0x88 - read (n*8) bytes, with n = 1..17 (page)
Default: 08 (read 8 bytes)
