Enabling "Wake-up on USB" functionality
When you connect the Mk3 Operating Panel to the HT20470 Processor Unit, you can choose to turn on the sonar system by simply touching one of the buttons or controllers on the panel. The computer BIOS (Basic Input/Output System) must be modified to support this functionality.
Prerequisites
It is assumed that you are familiar with common BIOS (Basic Input/Output System) functionality. Neither tools nor instruments are required. We suggest that you use a computer keyboard and mouse for this task.
Note
This procedure only applies to the HT20470 Processor Unit.
Context
The Processor Unit offers several USB interface sockets. The USB sockets can be used to interface peripheral devices such as USB flash drives, portable hard disks, mouse and keyboard.
Dedicated USB ports are provided for the "Wake-up on USB" functionality. "Wake-up on USB" means that you can turn on the sonar system by activating any USB device connected to a compatible USB port. The computer BIOS (Basic Input/Output System) must be modified to support this functionality.

Tip
If you choose to enable the "Wake-up on USB" functionality, it may not be appropriate for the entire sonar system to start up when you accidentally touch the operating panel. You can prevent the sonar program from starting when the Processor Unit is turned on.
To start the program - and turn on the entire sonar system - you must then double-click the sonar icon on the Processor Unit desktop.
Procedure
1 Restart the Processor Unit.
2 During the boot sequence, when prompted, press DEL to run the setup program.
Observe that the program starts.
Use the arrow keys on the keyboard to move the cursor.
Press Escape on the keyboard to go one step "back". In some situations, Escape will attempt to close the BIOS setup program.
3 Select Advanced on the Main menu.
4 Select USB Configuration.
5 Set USB S5 Wake-up support to Enabled.
6 Press Escape to return to the Main menu.
7 Save the chosen parameters, and exit.
a Select Save & Exit on the Main menu.
b Select Save Changes and Exit.
c When asked if you wish to save the configuration and exit, select Yes.
d Allow the Processor Unit to restart.
