User LED Indications
Audio Sound
An audio signal (default ON) provides a quick indication if a scan passes or fails
the current test. After a scan, one short, high pitch beep indicates that the
symbol passes an appropriate group of tests, while one long, low pitch beep
indicates that it fails.
Special Features
Reflectometer Mode
In the Reflectometer mode, the QC890 operates as a free-running reflectometer.
See "Reflectometer Mode" on page 3-6 for additional information.
Unrecognized Symbology Mode
The QC890 analyzes bar/space patterns that are not decodable or are not
among the unit’s available symbologies. This technical feature is useful for
making contrast measurements, for which decoding is not necessary, on
damaged or partial symbols, printer test patterns, and new or developing
symbologies. We recommend this feature only be enabled for these purposes.
Physical Connections
A DC power barrel on the back of the unit connects to a power supply for external
power and battery charging.
The DB9 port on the unit connects to the pen wand, mouse wand, or linear
imager. Refer to "Scanning Properly Using the QC3800VE Linear Imager:" on
page 3-5 . If you are using any of these devices, refer to "Scanning Properly
Using a Pen/Mouse Wand" on page 3-3 for additional information.
The RJ45 ten pin connector provides the USB or RS-232 serial interface to the
host. Refer to "USB Communication Interface" on page 2-2 and "RS-232 Serial
Communication Interface" on page 2-3 for details on connecting your unit.
