A.11. Programming the Translation Table
The ID4100 has a translation table facility that allows a translation table to
be imported into the reader. This facility serves three primary functions:
h Support the use of legacy tags.
h Manage exceptions, such as the black-listing of tags.
h Serve as the list of allowed (and/or black-listed) tags for a standalone
access control system (See Standalone Reader Operation Application
Note).
Translation Table Format
The translation table uses a comma-separated variable (csv) format and will
typically have a .csv extension. The first line of the file must contain the
version number of the file format. Currently the file format version is 1.0.
Each subsequent line of the file represents a sequence of tags and has the
following format:
[StartID],[TagType],[StartXlateID],[Entries],[Handler
]<CR><LF>
where:
[StartID] is the first tag ID of a sequence of tag IDs. In most cases,
this is a hexadecimal number, preceded by 0x. If the tag protocol is
configured to display tag IDs in 6 bit ASCII format, this is the ASCII string
representing the starting tag ID. In the ASCII tag case, this is typically a
4 letter identifier followed by a 8 digit decimal number.
[TagType] is the tag protocol type. This must be one of the protocols
supported by the reader, for example, ISOC or ISOB.
[StartXlateID] is the first translated ID (in hex) of a sequence of
translated IDs. The number is preceded by 0x.
[Entries] is presented as a decimal number representing the
number of tags in the sequence.
[Handler] determines how the ID4100 should process a tag and is a
decimal number (between 0 and 255) that applies to all tags in the
sequence. Where:
Bit 7: Password Authentication Indicator
1 = Password Authenticated
0 = Not Password Authenticated
Bit 6: Blacklist Indicator
1 = Blacklisted
0 = not Blacklisted
