4.2 Datalogger Initiated Communications
The datalogger can call the computer to initiate data collection, sometimes
termed "call back." Instruction 97, Initiate Telecommunications, is used for
this purpose. Call back is commonly used to initiate data collection under
emergency situations (e.g., water level falls below lower limit). Call back is not
the preferred method for routine data collection.
The computer must be left on and dedicated to RF communication to
implement the call back option. Call back instructions are explained in the
datalogger manual. The PC208W Manual explains the use of call back in a
telecommunications network.
