Chapter 18 Control Commands - Denso QB30-SR User Manual

Chapter 18 Control Commands

The commands which are transmitted between the host unit and the scanner through the communication line are called the
control commands.
Items set by control commands from the host unit overlap those indicated in "Parameter setting by QR Code parameter
menu/Configuration software (QB Setting)". Designation by the control command prevails over that by the QR Code
parameter menu. However, unless a PW command is given, the value set with the control command will not be stored in the
internal FLASH ROM, and therefore if the power is turned OFF, all designations made with control commands will be cleared
and only the parameter setting by QR Code menu/Configuration software (QB Setting) is valid.
If commands other than ones listed below are sent to the scanner, the scanner operation is not assured.
Note: Selecting the USB keyboard interface disables the control commands.
Note: Until the completion of execution of a specified control command, the subsequent command will not be executed.
Note: After recognition of the virtual COM port when the USB-COM interface is used, the scanner requires a maximum of
one second to be ready to receive control commands.
