216 700 Series Color Mobile Computer User’s Manual
Scanner Cabling
A null modem cable is required for the Welch Allyn 1470 Imager to com-
municate with the 700 Color Computer when using the 700 Color Serial
Cable (P/N: 226-999-001).
Sabre 1551E / 1553 Cables connect directly to the Model 700 COM Port.
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 this 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 these capabilities:
S Grid Data Editing is available.
S The source of the symbology configurations is only available via the
Easy Set command labels. You can only configure the Virtual Wedge
configurations via the Data Collection control panel applet Virtual
Wedge page. See Appendix A, “Configurable Settings,” for information.
S May transmit the data through the keyboard interface (via the Virtual
Wedge).
