11 Hardware Features
11.1 Keypad
The DSVII-SC
®
comes equipped with an intuitive 4-function
keypad, shown at right. The keys are vertically aligned along the
left side of the LCD display, enabling application software to
position virtual “buttons” appropriately. These keys are
programmed as WinCE standard “F1” through “F4” keys, though
this can be changed by a registry setting.
Below the function keys is the power switch. You must depress
and hold it until a single beep is heard, then immediately release
it for an additional two beeps. Holding the button too long will
cause an “error” type beep sound and the system will not be
powered up or down, as the case may be. This procedure helps to
guard against accidental activation or shutdown of the system.
11.2 Fingerprint Sensor, LCD & Indicators
The top of the front case features the fingerprint sensor (upper left) and LCD display. The LCD is color, and comes
with white-LED backlighting that can be adjusted through a control-panel setting.
The power switch has a bi-color (red/green) backlight indicator, which identifies whether the system is on, charging,
or running low on battery power.
11.3 Serial Ports
The DSVII-SC
®
has one external serial port available for
interfacing to a host computer or other external equipment. Shown
here is the I/O connector panel, which includes the serial port,
USB ports, CF-slot (not visible) and 10/100 LAN port.

NOTE: For developers, establishing an “ActiveSync”
serial connection with a host-PC will require a Datastrip serial-port cable plus a null-modem cable. These are
available through Datastrip Inc., Datastrip Ltd, or your authorized Datastrip reseller. The serial cable and
null-modem cable is supplied free with Datastrip2D SDK.
