The command is designed to switch on periodic data output. After processing the command the sensor performs periodic data output in the text-based form (ASCII codes) of the following data: relative level, temperature, frequency.

The data are being output periodically with an interval set up when cofiguring the sensor (Omnicomm Configurator software). In case the data output interval is set to zero, the data output won't be performed.

Switching on of the periodic data output is done by sending of the “DP” symbols in line. After processing of the command the symbols line will be received. For example, F=0AF9 t=1A N=03FF.0 <CR><LF>, where F is the current frequency value, t is the current value of temperature in Celcius degrees, N is the level value. Turning off of the periodic data output is performed after receipt of any true command, reset of the processor or disconnection of power supply.
