  QB30 2D

Compact housing suitable for embedded architecture

Strictly pursues "installation space saving" and "high Internal environment performance" required for built-on scanners.

  • QB30-SR (RS-232C model)
  • QB30-SU (USB model)

Scanning performance

Utilizing the technology developed as a manufacturer of QR code, ideal scanning performance has been achieved.

  • Scanning ON/OFF
  • Scanning codes
  • Shutter timing
  • Gain switching
  • Lighting LED controlling, etc.

Buzzer, LED, Magic Key

setting 2

  • Power LED: Orange color shows power status
  • Scanning Confirmation LED & Buzzer: Three colors of LED lights (blue, green, red) can be used to check the status of scans or notify operator of scanning completion or scanning error
  • Magic key: Controls "Scanning ON/OFF" and "USB keyboard I/F" and "USB-COM I/F"(1)
  1. I/F switching is available only for USB model.

Other Functions

Data Edit

Data edit

Corresponds to simplified programming language "ADF script." You can edit the data freely and the load on the host device can be reduced.

Data Collation

Data collation

By the registration of the master data, collation with the scanned data is available.

Collation Mode Description
1.Scanning Input Mode After receiving the "master registration command" from the host device, the first scanned data is registered as a master data for comparison and verification.
2.File Input Mode Master data (up to 50 codes) must be transmitted from the host device to the QB30 in advance, allowing comparison and verification among multiple scanned items.

QB30-SR (RS-232C model)

I/O model (QB30-SR)

QB30 has I/O function through a mini Dsub-15 pin connector. When supplied with +5V power, I/O can be controlled from the host device, so an additional AC adapter is not required.

  Abbreviation Purpose I/O QB30   Abbreviation Purpose I/O QB30
1 No Connection No connection (1) - 9 TRIGGER Trigger input Input
2 TXD Transmitted data Output 10 RESET Reset Input
3 RXD Received data Input 11 OUT1 Output terminal 1 Output
4 CTS Clear to send Input 12 No Connection No connection (1) -
5 RTS Request to send Output 13 OUT2 Output terminal 2 Output
6 GND Common ground - 14 COM OUT Common output (2) Output
7 No Connection No connection (1) - 15 +5V Power -
8 COM IN Common input (2) Input/Output

Example:Production line and Specimen device

Example:Production line and Specimen device

If a trigger signal is transmitted to the QB30 with precise timing, the codes on the specimens are scanned according to the signals. If a read error occurs, an NG signal is transmitted from the output terminal (i.e. Patlite).

  1. Please don't connect to pin 1, 7, 12.
  2. Isolated from the ground of QB30.
