Appendix 2 Control Commands - Denso AT10Q-SM User Manual

Appendix 2 Control Commands

Control commands refer to commands that are exchanged between the host computer and the scanner via the
communications line.
Some of the control commands that the host computer issues are functionally equivalent to some parameters that can
be set with the QR-coded parameter menu (refer to Chapter 11). Control command settings have priority over settings
made with the QR-coded parameter menu.
Note that turning off the scanner will clear control command settings so that settings made with the QR-coded
parameter menu will take effect unless the PW command is sent to the scanner for saving control command settings
into the EEPROM.
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.
