Quadrus MINI Imager User’s Manual
USB HID Interface
USB HID Configuration Options
The user has the following options for configuring and defaulting a USB version of the
Quadrus MINI:
Configuration Symbols (Data Matrix with “Configure Reader” Flag)
Symbol configuration can be performed “out-of-the-box”, as the Quadrus MINI is configured
for Continuous Read Mode, and Data Matrix is enabled by default. Data Matrix symbols
are used to encode configuration commands when the symbology’s “configure reader” flag
is set.
If the read cycle is changed, or if Data Matrix is disabled, another configuration/default
method must be used. This is because the USB Quadrus MINI has no external trigger,
unless the user has configured the EZ button as a trigger.
EZ Button Configuration
By default, basic calibration can be initiated from the EZ button (3 beeps). Note that this
only changes the camera, image processing, and symbology settings of the imager. To
default the USB Quadrus MINI, hold down the EZ button during power-on.
Note: This only overwrites Power-On settings with Custom Default settings, as when the
<Zrc> command is received. It does
not
overwrite Power-On settings with Factory
Defaults, as when the <Zrd> command is received. If Custom Defaults are misconfigured,
another method must be used to default the imager.
Implementing the Host Operating System API and Establishing a
Connection with the Microscan HID Interface
When a connection is made, the host can send serial configuration/default commands. The
imager will always be able to receive configuration commands from the host application and
send responses to those commands. However, the imager can be configured to stop producing
IN Reports to the host from symbol data output and diagnostics (service messages).
