Refer to the TLA7UP Mainframe Field Upgrade Instruction Manual for instructions for
updating module firmware.
Updating or Restoring the Logic Analyzer Firmware
You may have to update the firmware on the logic analyzer module if the module
does not appear in the TLA System window after you have serviced the module
or after you have updated the TLA application software on the mainframe. You
can update multiple modules and module types during a single firmware update
session. The most current firmware resides on a file on the hard disk of the logic
analyzer mainframe.
1. Note which of the modules that may require new firmware.
If any modules are missing from the System window, you can verify the
status of the modules by doing the following steps:
a. Select System Properties from the System menu.
b. Click the Modules tab.
c. Note the information under the Messages column for any installed
modules. If any modules indicate invalid or similar messages, you must
update the firmware for those modules.
2. Disconnect any probes connected to the modules that you want to update.
3.
Exit the logic analyzer application.
