9457 Industrial Computer
4-2
The built-in mouse consists of three basic parts:
Left Mouse Key
This key serves the same function as the left button on a conven-
tional mouse.
Mouse Dome
This dome is used to move the mouse pointer around the screen.
Press the edge of the dome that corresponds to the direction in
which you wish to move the pointer.
Right Mouse Key
This key serves the same function as the right button on a conven-
tional mouse.
System Status LEDs
The 9457 monitor module features five status LEDs on its front panel, which you can use
to monitor system operation. To use these LEDs, you must have installed the Host/LED
cable between the monitor module and the computer module.
The System Status LEDs are
Fault
Lights when an error is detected during the Power On Self-Test, as
described below.
Maint
Lights when the computer module has been used for a sufficient
number of hours to require routine maintenance.
Power
Lights when power is applied to the computer module.
Disk
Lights when the computer module accesses the hard drive.
Com
Lights when there is communication activity on one of the com-
puter module’s serial ports, including communication between the
computer module and the built-in mouse or optional touch screen
on the monitor module.
During power-up, firmware on the processor board checks the hardware configuration
against the configuration information stored in the CMOS memory. If the Power On Self-
Test (POST) is successful, the Maint and Fault LEDs will be extinguished. The Maint,
Fault and Power LEDs indicate the system’s status as follows:
