Using TSP
Do not turn off power or remove the USB flash drive until the upgrade process is complete.
Using TSP over a remote interface:
1. Copy the firmware upgrade file to a USB flash drive.
2. Verify that the upgrade file is in the root subdirectory of the flash drive and that it is the only
firmware file in that location.
3. Disconnect the input and output terminals that are attached to the instrument.
4. Turn the instrument power off. Wait a few seconds.
5. Turn the instrument power on.
6. Insert the flash drive into the USB port on the front panel of the instrument.
7. To upgrade to a newer version of firmware, send:
upgrade.unit()
8. To return to a previous version of firmware, send:
upgrade.previous()
9. After completion of the upgrade, reboot the instrument.
A message is displayed on the front panel of the instrument while the upgrade is in progress. In
addition, the LEDs in the upper right of the front panel blink while the upgrade is in process.
