USB HID Interface
USB HID Interface
The USB version of the EZ Match Imager operates as an HID (Human Interface Device)
on the USB bus. HID-class devices communicate via “report” packets. An HID may support
multiple report types, each of which is identified with a unique report ID. The EZ Match
supports two different report types:
•
Microscan HID Report
(ID = 1)
•
Keyboard Report
(ID = 2)
The imager always outputs the same data for both report types. The user may enable or
disable either report type.
Regardless of the report type used by the host application, the application protocol via USB
is identical to RS-232 / RS-422 ports.
HID Reports
are used as a channel for standard
Microscan imager communication, command input, and symbol data output.
Important:
No matter how the imager is configured, it is always able to receive and
respond to commands from the host application using
Microscan HID Reports
.
