Added switch command description 16.12.15 M. Gäth Consumed energy added (data output sting and getter/setter) Added power commands to read single sensor value Changed OutputEnable/LogEnable to configurable intervals Changed temperature fuse characteristics (reset threshold instead of reset time) SmartPowerSwitch_A2_UserManual.docx 3/24 develogic GmbH... -
Page 4: System Description
High pressure protection Simple On/off switching using the develogic Magnet Starter plug attached to the cap of the housing Switch signaling and battery voltage blinking through a bi-color LED RS232 interface for commanding, configuring, data output and log readout Less than 3µA current consumption if switch is off... -

To assure an operating depth of 6000m, sealing compound was used to seal the opening of the plug. Chapter III describes the Magnet Starter plug usage in detail. The serial port is used for configuration of the Smart Power Switch and the log readout. Chapter IV describes the serial port usage in detail.
