Connecting Serial Scanner Cradle to COM1 Connector
Figure 5-83
NOTE The connected scanner is powered from the COM1 port of the VC70.
By default, after the VC70 boots, the COM1 port remains powered off.
In the current revision (C), scanner power is enabled whenever the scan application starts (the scan
application calls Com open as in the standard CE Com port API). Power to the scanner is disabled when
the scan application is closed (when the scan application calls Com close).
The current revision (C) differs from the legacy revision (B) where the user manually enabled the scanner
power via applet or registry settings.
To enable scanner power in revision C via the applet or registry (as in revision B), refer to COM1 Power
Output to Scanner on page 11-4. When the scanner is enabled via the applet or registry, the scanner
power remains on (the Com port API is overwritten on the scanner power control and the scanner power
will not turn off when the scan application calls Com close).
