These objects use proprietary tags. The use of these tags should be restricted to the serial
interface. After the reader has returned an OK response frame, the terminal application should
dispose of the tags to avoid conflicts with other proprietary TLVs. .
IMPORTANT NOTE:
Many
two-bytes tags that begin 'FF' have been superseded with BER-legal three-byte tags. See
4.3.2.
Discover Group Configuration TLVs
Discover uses Group B0 as default Group. The
Set Configurable Group
command should be
used to set the TLVs in this section. The following table in this section shows TLVs in Discover
Configuration Group.
Vendi rule
for Discover Configuration Group:
If a TLV value is absent in Discover Group, reader will use the value in Group 0, except 3 TLVs
below:
For transaction limit (DFEE34), CVM limit (DFEE36), floor limit (9F1B): if user-defined TLV
Group is used, user should set these above TLVs in the user-defined Group. If not set, these
above TLVs will be regard as not present.
Vendi rule for Discover Configuration Group:
The following Discover Group TLVs should not be configured for Group 0. The default
Discover group is Group B0. That is, when the reader is configured from the factory, the
Discover System AIDs will be associated with Group B0.
If there are tags in a Discover group that should be set, they must all be set explicitly,
because the absent values
are not
filled in with Group 0 defaults.
Discover Group tags are instantiated differently than other groups. Group 0 is never used as a
default. Refer to the section on
for an explanation of how the tag
database is instantiated for Discover
.
