  • Page 22: Chapter 6 Reading Control

    Chapter 6 Reading Control Two types of reading controls are available--Trigger switch control and Software control. Trigger switch control: Pressing the trigger switch readies the scanner for reading. (Refer to Section 6.1.) Software control: Instead of pressing the trigger switch, you send control commands from the host computer via the RS-232C or USB-COM interface to ready the scanner for reading or put the scanner on standby.

  • Page 23: Software Control

    6.2 Software Control You can control the scanner by sending reading control commands from the host computer via the RS-232C or USB-COM interface, instead of pressing the trigger switch. Reading control commands include R, READON, LON, Z, READOFF and LOFF and are restricted by the trigger switch operating modes, as listed below.
  • Page 24 Note: Even if you do not bring a barcode label within the scan range, the illumination LEDs may come on when the ambient level of light changes or any shadows move within the scan range. Note: To enable the scanner to work properly in auto sensing mode, an ambient illuminance of at least 500 lx is required.

  • Page 25: Chapter 7 Reading Functions

    Chapter 7 Reading Functions 7.1 Data Verification Mode The data verification mode verifies the barcode data read against the master data stored in the scanner and reports the match status with data output. Data verification read is available in two types--“n-point verification” and “2-point verification,” which can be selected with the configuration software (Scanner Setting).
  • Page 26  2-point verification Scan master registration 1) Switch the scanner to the data verification mode and select the RS-232C or USB-COM interface. The indicator LED lights in green. 2) Use the scanner to scan a master code to be registered. (The scanner operates in the trigger switch operating mode currently set.) After the registration of master data, the indicator LED turns blue and then goes OFF.
