4.Use your communication program’s (e.g. HyperTerminal’s) upload function to transfer the upgrade firmware to the unit. Select ASCII file format, and then specify the filename and directory location where the firmware upgrade file resides.
Note: The Upload function will time-out after one minute of inactivity. If the function times out, type 1 and press [Enter] to continue, or press [Esc] to abort.
5.If the upload is successful, the APS-8/16M will prompt the user to continue the upgrade or abort.
a)Upgrade: To continue with the upgrade, type 1 and press [Enter]. APS-8/16M will erase the previous firmware, move new firmware from data flash to program flash memory, calculate and store the new checksum, and reboot. Do not attempt to reconnect to the APS-8/16M until the RDY indicator blinks to indicate the process is complete.
Note: Do not turn off power to the APS-8/16M unit while the upgrade is in process.
b)Abort: To abort the procedure, type 2 and press [Enter].
6.Incomplete Upload: If the upload is interrupted, times-out, or if the file is corrupted during transfer, the APS-8/16M will display a screen which asks for user confirmation before proceeding. To proceed, type 1 and press [Enter], then return to Step 4 above.
7.Emergency Recovery: In the rare event that the APS-8/16M operating system becomes corrupted during installation, front panel indicators will blink five times and the unit will automatically switch to Emergency Recovery Mode. Please contact WTI Customer Service for further instructions.
When firmware upgrades are available, WTI will provide the necessary files via modem or mailed diskette. At that time, an updated Users Guide or addendum will also be available.
