Appendix 2 Control Commands - Denso GT10Q-SR User Manual

Appendix 2 Control Commands

Control commands refer to commands that are exchanged between the host PC and the scanner via the communications
line.
Some of the control commands that the host PC 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.
