Configuring the AP4118 Rail Tag Programmer
This chapter briefly defines permissions and instructs how to configure
the AP4118 Rail Tag Programmer using an PT5780 or PT5785
Permissions Tag.
Permissions
An AP4118 Rail Tag Programmer requires specific setup data before it can be used to
program tags. Configuration of the programmer is done using a permissions tag. The
permissions tag transfers parameters, such as permissions expiration date, program-
ming session duration, programmer control number, and application tag permissions
(read/write/authentication access rights, and ownership matching) to the rail tag pro-
grammer via a RF signal. Initial tag programmer configuration can be performed at
the factory or at the customer site using a permissions tag.
Note: Use the PT5780 tag if configuring the AP4118 programmer for 902 to 928 MHz
frequency band tags and the PT5785 tag if configuring the AP4118 programmer for
860 to 880 MHz frequency band tags.
PT5780 and PT5785 Permissions Tags
TransCore’s permissions tag (
) is designed specifically to configure the
AP4118 Rail Tag Programmer. During programmer configuration, the permissions tag
data is validated by the programmer and, if valid, stored in the AP4118 tag program-
mer’s nonvolatile memory.
