CHAPTER 10: Upgrading Serial Port Manager Firmware

4. Use your communication program’s (for example, HyperTerminal’s) upload

function to transfer the upgrade firmware to the Serial Port Manager. Select
ASCII file format, then specify the filename and directory location where the
firmware upgrade file resides.

NOTE

The upload function times 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 Serial Port Manager prompts you to continue

the upgrade or abort.

a) Upgrade: To continue with the upgrade, type 

1

and press 

Enter

. The

Serial Port Manager erases the previous firmware, moves new firmware
from data flash to program flash memory, calculates and store the new
checksum, and reboots. Do not attempt to reconnect to the Serial Port
Manager until the RDY indicator blinks to indicate that the process is
complete.

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 Serial Port Manager displays a screen that 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 Serial Port Manager operating

system becomes corrupted during installation, front-panel indicators blink
five times and the unit automatically switches to emergency recovery mode.
Please contact Black Box Technical Support at 724-746-5500 for further
instructions.
