6 Scanner Support—Chapter
233700 Series Color Mobile Computer User’s Manual
Limitations and Capabilities
The Tethered Scanner has the following limitations:
S No auto detection of a scanner’ s physical connection to COM1 port.
User needs to ensure the communication settings of COM1 port
matched the settings of the device.
S The Pocket PC Pocket Office applications misbehave when control
characters such as carriage return are wedged. This is a known Pocket
PC problem, which is being worked with Microsoft and for which a
work around is being developed.
S Communications port is COM1 and cannot be changed.
S A complete bar code label is detected when the time between bytes (the
inter-byte gap) exceeds 100 ms. This allows that data could be concate-
nated if two labels were received while the Comm Port Wedge or the
1551/1553 Tethered Scanner was not performing a read. That is, it
could be wedging data just read or the read thread could be preempted.
Also, the labels could appear concatenated if the scanner itself were to
buffer the labels before transmitting them.
When enabled, the Comm Port Wedge menu option has the following
limitation:
S There is no bar code API to get bar code data from the bar code scan-
ner. The Comm Port Wedge transmits the data through the keyboard
interface only.
When enabled, the 1551/1553 menu option has the following capabilities:
S Grid Data Editing is available.
S The source of the symbology configurations is only available via the
Easy Set command labels. Only the Virtual Wedge configurations can be
configured via the Data Collection Control Panel Applet Virtual Wedge
page. See Appendix A, “Control Panel Applets,” for more information.
S May transmit the data through the keyboard interface (via the Virtual
Wedge).
