Programming the Translation Table
The 6204 has a translation table facility that allows a translation table to be
imported into the reader. This facility serves three primary functions:
Support the use of legacy tags.
Manage exceptions, such as the black-listing of tags.
Serve as the list of allowed (and/or black-listed) tags for a standalone
access control system (See Standalone Reader Operation Application
Note).
A.11.1.
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. The second line of the file may
optionally contain a string
FC_LEN=X,SNR_LEN=Y
, where
X
and
Y
are the
facility code and serial number bit lengths respectively. If present, this line
indicates how any decimal translated IDs in the rest of the file shall be
interpreted (i.e. how many bits are represented by each field). If not
present, a facility code length of 8 bits and a serial number length of 16 bits
is assumed. Note that currently the web interface (RCT) does not generate
this optional line, so any web-entered decimal Wiegand data assumes these
default bit field lengths.
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 of a sequence of translated
IDs. The number is preceded by
0x
. This value may be in hexadecimal
format (if preceded by 0x), or in decimal format with facility code and
serial number separated by a dash (i.e. "123-4567").
[Entries]
is presented as a decimal number representing the
number of tags in the sequence.

FC and SNR Values
FC and SNR Values FC and SNR Values FC and SNR Values
When populating the
translation table, specify
only values that can be
expressed in the number of
bits used for Facility Code
(FC) and Serial Number
(SNR).
For example, if 16 bit serial
numbers are used, then
only serial numbers in the
range of 0 through 65535
should be specified in the
table.
