TransCore AP4119 - Security Characters and Regulatory Region Settings

Chapter 3 Operating the Programmer
TransCore Proprietary

If the tag is placed during the 10-second period, the programmer reads the tag data, checks for
data integrity, and sends the tag data and a #Done response to the host system. If the tag is not slid
into the holder during the 10-second period, the programmer aborts the command and sends the
#Error<cr> response to the host.
If the verification process is not successful, repeat this sequence beginning at Step 1. Refer to
Table 7 for troubleshooting remedies.
Security Characters
The tag security character function prevents the use of unauthorized tags in TransCore electronic
identification systems. All AP4119 Rail Tag Programmers have the capability, when enabled by settings in
the PT5780 Permissions Tag, to program specific, predefined security characters into a tag. This capability
must be specified in an authorized TransCore order administration requisition. Security characters are
available for American Trucking Associations and International Standards Organization tag data formats.
When enabled, the security characters, which are specific 6-bit patterns designated for security coding
purposes, will be two specific characters from the list of security characters in Appendix F or one
character each from Appendix C and Appendix F.
When a tag programmer has tag security enabled, all tags programmed with secure characters will contain
the assigned security characters in the designated positions of the tag data. Security characters comprise
the second half of the 26th character through the first half of the 29th character when data is in the 4-bit
hex format. The security characters are the 18th and 19th of the 20 six-bit ASCII characters in the tag ATA
frame.
The programmer places security characters into their associated tag data locations, via the permissions
tag, when security characters in the tag data match the internal security characters stored in the
programmer.
The programmer will not store any security codes in a tag that dier from those stored in the programmer’s
internal memory. If you attempt to program the tag with security characters that do not match the internal
security characters of the programmer (i.e., incorrect or improperly obtained codes), the programmer
automatically programs the space character into both security character locations.
Regulatory Region
Warning: This equipment can be set to use frequency ranges NOT authorized for use within the
US/Canada and thus will NOT comply with FCC/IC frequency allocation requirements at those
frequencies.
Note: Users in countries other than US/Canada should check with the appropriate local authorities
for regulatory requirements.
The AP4119 Rail Tag Programmer contains a Frequency Hopping Spread Spectrum (FHSS) transceiver
module. The transceiver is pre-configured for dierent regulatory regions throughout the world. The
region code is set with command #642XX. The XX setting is defined inTable 5.
