MS-4X Imager User Manual
3-23
Communications
USB HID Interface
The USB version of the MS-4X 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 MS-4X 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.
