Action
Initiate the download by executing the proper
command(s) in the download tool running on
the host computer. The data transfer operation
starts, and the status messages are displayed
on the terminal screen.
The progress of the download is indicated by
a series of ten asterisks (each asterisk
indicates that 10% of the download is
complete). When the last asterisk is displayed,
the download is complete.
To stop the download operation, press the
CANCEL key. The terminal restarts
automatically.
When the download is complete, the terminal
restarts automatically. The file authentication
module on the receiving terminal begins to
check for new certificate (*.crt) and
signature (*.p7s) files included in the
download. These special files then process
one at a time; certificates process first, then
signature files.
When the file authentication module is
invoked, the status display informs you of the
progress of the file authentication process. If
file authentication succeeds for a specific
certificate, the "
AUTHENTIC
displayed directly below the certificate
filename. If file authentication fails for a
specific certificate, the "
FAILED
displayed for five seconds below the filename
and the terminal beeps three times, allowing
you to note which certificate failed to
authenticate.
The authentication process then continues to
the next certificate until all new certificates are
authenticated.
