Automatic Data Collection COM Interfaces

Multiple ADC COM Object Support

700 Series Monochrome Mobile Computer User's Manual
Data collection configuration and functionality cannot be accessed by any
means (including control panel applets or remote management applications)
until after the 700 Series Computer has completed initialization, which
occurs during a warm- or cold-boot or after a firmware upgrade.
When initialization is complete, the green LED on the 700 Series Com-
puter stops flashing. Changes made to configuration settings remain after a
warm boot. After a cold-boot, all configuration settings are reset to their
defaults with the exception of scanner configurations, which remain except
for the Symbology Identifier transmission option or the Preamble and
Postamble strings. To reset all configuration settings to the factory de-
faults, the S9C scanner firmware must be reloaded.
The Automatic Data Collection (ADC) functions are accessed through
custom COM interfaces. These interfaces allow the application to receive
bar code data and configure and control the bar code reader engine. The
COM interfaces include the following functions:
S IADC (starting on page 156)
S IBarCodeReaderControl (starting on page 164)
S IS9CConfig (starting on page 176)
S IS9CConfig2 (starting on page 218)
S IS9CConfig3 (starting on page 235)
A 700 Series Computer may have multiple reader engines to decode differ-
ent types of ADC data. For example, a bar code reader engine decodes raw
bar code data and passes it to a bar code reader COM object. An RFID
reader engine decodes raw RFID tag data and passes it to an RFID tag
reader COM object.
ADC COM interfaces are implemented as in-process COM objects. An
instance of the ADC COM object creates a logical connection to access or
control the reader engine. Specifically, the IBarCodeReadConfig or IBar-
CodeReaderControl COM objects can manage the bar code scanner con-
figuration while the ADC COM object can gather data simultaneously.
These ADC COM objects or connections can be created in a single ap-
plication or multiple applications. Up to seven instances of a COM object
can be created for a reader engine. For more information, see "How to
Create and Use the ADC COM Interfaces" on the next page.
For data collection features, ADC COM objects also provide for read
ahead data access and grid data editing.
