oh i guess you are correct:
If the AquaControllerJr is purchased with the optional serial port it can be connected to PC via a standard RS-232 cable (available from Neptune Systems). The serial interface allows you to download the datalog log as well as retrieve the current status of the monitored parameters and controlled devices in the aquarium. A computer is NOT required to program or operate the AquaController Jr.
