Configuring and Updating the SP-II TPU

The SP-II TPU is configured at the factory. However, should changes be required,
configuring and updating the SP-II TPU can be performed using Linux Updater.
This program is automatically installed when installing SonarPro 12.1 and can be
used to perform the following tasks:
• Query or change the IP address of the SP-II TPU.
• Edit the startup file of the SP-II TPU.
• Download and install software updates to the SP-II TPU.
