Panel
The system control panel at the top front of the cart is a replaceable, self-contained module. See
“Replacing the System Control Panel” on page 159. The panel interfaces with the imaging system
through a USB cable that connects to the internal PC. Power for the trackball is provided via the
USB cable. All the other control-panel functions are powered by a cable from the system power
supply.
The system control panel contains a backlit alphanumeric keyboard, slide controls, rotary
controls, hard-coded and software-driven keys, and a trackball.
