Chapter 11 Communication
The scanner is compliant with USB 1.1 (Universal Serial Bus Specification, Revision 1.1).
11.1 USB Keyboard Interface
The USB keyboard interface requires no dedicated device driver. Data read by the scanner can be entered to the cursor
position in your application.
The USB keyboard interface operates in conformity with the following:
- Universal Serial Bus (USB) Device Class Definition for Human Interface Devices (HID) Version 1.11
- Universal Serial Bus (USB) HID Usage Tables Version 1.11 keyboard
(1) CAPS Lock state
Select the CAPS Lock ON or OFF to match the state of the connected keyboard. (Default: CAPS Lock OFF)
(2) Keyboard type
Select the type of the connected keyboard. (Default: Type 101, US English)
(3) Data transmission interval
You can select the data transmission interval to be applied when the scanner sends data read to the host computer. There
are seven choices from 3 ms to 100 ms (default: 10 ms).
11.2 USB-COM Interface
Installing our virtual COM port driver "USB-COM device driver" to the host computer enables the scanner to operate with
communications software that uses a conventional RS-232C serial port.
The virtual COM port on the computer and the scanner are connected with each other as shown below.
It is not necessary to make settings such as transmission speed, data bits, parity, and stop bits (which are required for
communications software using a conventional serial port) since the USB interface ignores those settings.
The flow control should be set to "Hardware (RTS/CTS)" or "None."
The RTS signal at the scanner is always enabled.
The communications parameters can be set with the bar-coded parameter menu or configuration software (ScannerSetting).
Bar code data scanned will be transferred in the format shown in Section 10.3.
