USB reader configuration
The USB interface is available for the PScan-D-1D-D2 device and is
compatible with the following Operating Systems:
Windows 98 (and later)
IBM POS for Windows
Mac OS 8.0 (and later)
4690 Operating System
USB Start-up
As with all USB devices, upon connection, the host performs several
checks by communicating with the device. During this phase, normal
operations are suspended (the LED on the PSCAN-D-1D-D2 reader
blinks). Two basic conditions must be met before the device is ready—the
correct USB driver must be loaded and sufficient power must be supplied
to the reader.
1. For all systems, the correct USB driver for the default USB-KBD
interface is included in the host operating system and will either be
loaded automatically or will be suggested by the O.S. and should
therefore be selected from the dialog box (the first time only).
Normally, the host supplies sufficient power to the device and the
start-up phase ends correctly. (The reader's LED stops blinking and
the reader emits the beep OK signal). In rare cases, if the host does
not supply sufficient power to the device, a dialog box will appear on
the host and the device will be blocked (the reader's LED continues
blinking). In this case, disconnect the USB device cable at the host
(the reader's LED stops blinking), and then try a different USB port
as indicated by the operating system message. (The device emits the
beep OK signal. You can now read codes).
2. At this point, you can read the USB interface configuration code
according to your application. Load drivers from the O.S. (if requested).
When configuring the USB-COM interface, the relevant files and drivers
must be installed from the USB Device Installation software, which can
be downloaded at http://www.scanning.datalogic.com.
The device is ready. Successive start-ups will automatically recognize the
previously loaded drivers
Changing default settings
Once your reader is set up, you can change the default parameters to
meet your application needs. Refer to the preceding paragraphs for initial
configuration in order to set the default values and select the interface
for your application. In this manual, the configuration parameters are
divided into logical groups making it easy to find the desired function
based on its reference group.
The following parameter groups are common to all interface applications:
DATA FORMAT
parameters regarding the messages sent to the host
system.
POWER SAVE
manages overall current consumption in the reading device.
READING PARAMETERS
control various operating modes and indicator
status functioning.
DECODING PARAMETERS
maintain correct barcode decoding in certain
special reading conditions.
CODE SELECTION
parameters allow configuration of a personalized mix of
codes, code families, and their options.
ADVANCED FORMATTING PARAMETER
S allow code concatenation and
advanced formatting of messages
