Operating Modes
A limited number of settings can also be defined without using the AT command
interface by interrupting power supply to the unit several times in a row using a
defined time pattern.
The WSA has several operating modes that can in part be achieved by using
suitable AT commands, but also by targeted disruption of the power supply of the
device. The latter is then required if no RS-232 link is available or the AT
command interface is no longer accessible. That is the case when the settings of
the RS-232 interface and/or the authentication settings for the SSP service
“CONFIG” have been changed and then are no longer available.
For a detailed description about switching of operating modes, refer to the section
“Commissioning”> … >“Switching of Operating Modes.”
