When the OS download is complete, the terminal restarts automatically.
The file authentication module on the receiving terminal then checks for
new certificate (*.crt) and signature (*.p7s) files included in the download.
It processes these special files one at a time; certificates are processed
first, then signature files.
When the file authentication module is invoked, the progress of the file
authentication process displays. If file authentication succeeds for a
specific certificate, the “
AUTHENTIC” message displays directly below the
certificate filename. If file authentication fails for a specific certificate, the
“
FAILED” message displays 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 checked.

**AUTHENTIC**
or else
--- FAILED ---
The file authentication module proceeds to authenticate new signature
files downloaded with the OS files. When the signature file authentication
routine begins, the progress of the authentication process displays. If file
authentication succeeds for a specific signature file, the “
AUTHENTIC”
message displays directly below the filename of the signature file. If file
authentication fails for a specific signature file, the “
FAILED” message
displays for five seconds below the filename and the terminal beeps three
times, allowing you to note which signature file failed to authenticate.
The authentication process proceeds to the next signature file until all
signature files are validated. When file authentication is complete, the
terminal either restarts automatically and begins processing the new OS
(full download) or it returns control to system mode (partial download).
If you are performing a partial download, the terminal does not restart until
manually initiated by pressing F4 in
SYS MODE MENU 1. If an application
resides on the terminal following the OS download, it executes and starts
running on restart.
Note: Because a full OS download clears the RAM, all terminal
applications and related certificate and signature files must
download to the terminal when performing this type of download.
8 (Application Prompt)
or
DOWNLOAD NEEDED
If you performed a full OS download, the DOWNLOAD NEEDED prompt
displays.
At this point, you can perform a direct application download on the
receiving terminal.
If you performed a partial OS download and manually restarted the
terminal, the application residing in the terminal (if any) executes. The
application prompt displays on terminal restart, after OS processing, and
the application starts running.
