Automatic Data Collection Functions; Desktop Configuration Functions; Quickwin Functions - Intermec Data Collection PC User Manual

UDP Plus protocol functions expose a minimal emulated Winsock 1.1 API as its
application-level interface on the 5020. This API provides a sockets-based method to
support UDP Plus transactions.
•
Only one socket is allowed since the UDP Plus protocol does not allow more than
one connection.
•
The UDP Plus system supports a second communication mode, the Reader
Command gateway. The Reader Command gateway allows configuration messages
(TMF Reader Commands) to be sent to the 5020 via the DCS 300. The TMF Reader
Commands are compatible with other Intermec devices such as TRAKKER Antares
and JANUS.
•
Only one UDP Plus socket client for data transmissions is allowed at a time by this
emulation layer, while concurrently providing configuration transactions. Non-
Unicode string parameters are used in UDP Plus protocol functions.

Automatic Data Collection Functions

The ADC functions are accessed through custom COM interfaces. These COM
interfaces allow the application to receive bar code data, configure the bar code reader
engine, and control the bar code reader engine. In addition, the COM interfaces allow
applications to specify the data it will receive. The COM interfaces are:
IADC Provides ADC data in an input device independent manner. On a 5020, there
may be multiple reader engines to decode different 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.
IBarCodeReaderConfig Allows the application to directly configure the bar code
reader engine and to get statistics.
IBarCodeReaderControl Allows the application to trigger the bar code laser scanner,
disable the scanner, and receive bar codes with data details such as symbology scanned,
data type (Unicode, ASCII, or other), and the time the data was received. This interface
also allows the application to specify a data grid to filter ADC data.

Desktop Configuration Functions

Desktop Configuration functions allow you to customize the 5020 desktop.

QuickWin Functions

QuickWin functions allow you to create a simple Windows CE data collection
application. You can create a VT like terminal screen that occupies the entire display on
a 5020. You can create label prompts and edit fields on the display and receive input
from the edit fields.
