CONTROL PANEL<br />

The Mobile C-Arm contains two identical, external control panels. Each control<br />

panel consists of a 20 character Vacuum Fluorescent Display (VFD), fourteen<br />

LED's, and a twenty three position matrix keypad. Software on the Control Panel<br />

Processor PCB continuously scans the keypads to determine if any keys have<br />

been pressed. Each key is identified by a row number and a column number and<br />

is encoded as a hex value. This hex value is sent to the Technique Processor<br />

PCB when a key is pressed.<br />
