Appendix 2 Control Commands
Control commands refer to commands that are exchanged between the host computer and the scanner via the communications
line.
Control commands can be used only when a connection using SPP profile is established.
Some of the control commands that the host computer issues are functionally equivalent to some parameters that can be set
with the Bar-coded parameter menu (refer to Chapter 10). Control command settings have priority over settings made with the
Bar-coded parameter menu.
Note that turning off the scanner will clear control command settings so that settings made with the Bar-coded parameter
menu will take effect unless the PW command is sent to the scanner for saving control command settings into the FLASH
ROM.
If commands other than ones listed below are sent to the scanner, the scanner operation is not assured.
