up to 34 seven-bit ASCII characters.
Tag Data Formats
Tags are programmed at the TransCore factory with the tag model number, date of
manufacture, and data format. Contact TransCore for special order entry procedures
for the format that applies to your system. The following four tag data formats can be
used:
• 10-character alphanumeric ASCII — Four alphanumeric characters are fixed and
can be used to identify either the dealer or the user. The remaining six positions
are numeric and should be unique for each tag issued. For example, the entry
ACME000001 might be specified as the first tag on the order entry form from
ACME Parking Garage.
• 20-character alphanumeric ASCII — Four alphanumeric characters are typically
fixed and the remaining 16 positions are numbered sequentially.
• Wiegand — Tags can be programmed in Wiegand formats with 26 to 54 bits. If
you choose this format, complete a Wiegand format worksheet — attached to the
order entry form — indicating the data to be programmed into the tags.
Note: Security access control tag models can be Wiegand-formatted. SeeTable E-1
through Table E-3 for Wiegand-compatible tag models.
