TMT250 User interface

Indication is configurable in User Interface tab of configurator or via SMS/GPRS parameter ID. Each 100 ms device checks if any indication is enabled in response to triggered scenarios. If two scenarios need to indicate on the same indication source (LED or Vibration) then the active indicating scenario needs to be finished first (with exception of Alarm and Device Off scenarios, which can override the control of indication sources). Period setting is indicative of Periodic scenarios and if Period is set to 0 the indication will take place immediately. When indication is periodic and On parameter value is set to 0, the indication source will stay on until the scenario is finished. Triggered scenarios will turn on LED and/or Vibration for a configured On duration and then keep them off for a configured Off period of time. In case the configured Repeat value is higher than 0 the device continues a periodic on/off cycle. Enable In Sleep parameter will let the indication work while device is sleeping.
