10. Upgrading APS-8M Firmware
When new, improved versions of the APS-8M operating firmware
become available, the /UF (Upgrade Firmware) function can be
used to update the APS-8M unit to the new firmware version.
Updates can be uploaded to the unit via SetUp Ports one and two,
or via the internal modem port (Port 8). To install a firmware
update, proceed as follows:
Note: All other ports will be disabled during the
firmware upgrade procedure.
1. Obtain the update file. Firmware modifications can either
be mailed to the customer on a 3.5" diskette, or
downloaded from WTI via modem. Place the diskette in
your diskette drive and/or copy the file to your hard drive.
2. Access the APS command mode. If the password prompt is
displayed, key in the Supervisor Password. The Upgrade
Firmware feature is only available in Supervisor Mode.
3. When the APS command prompt appears, type /UF and
then press [Enter]. The APS-8M will display a screen
which offers the following options:
a) Continue Upload and Keep Current Parameters: To
proceed with the upgrade, while retaining current, user-
defined parameters, type 1 and press [Enter]. All
parameter settings will be restored when the upgrade is
complete.
b) Continue Upload and Default System: To proceed
with the upgrade, and reset parameters to default
settings, type 2 and press [Enter]. When the upgrade
is complete, all parameters will be set to default values.
Note that if the Firmware Upgrade is performed via
modem, Modem Port parameters will not be defaulted
until after you hang-up and disconnect from the unit.
c) Abort Upload: To cancel the upgrade and return to the
command prompt, type 3 and press [Enter].
