4.6 Compact Flash card interface
4.7 Remote control interface
The remote control interface of the CT Analyzer is exclusively intended to connect the CT Analyzer to a
computer (e.g. running the CT Analyzer PC Toolset software) or to the optional CT SB2 switch box (for
multi-ratio CT measurement).
As of serial number JHxxxx or newer, the CT Analyzer is equipped with a USB interface and a RS232
interface.
Note: The user has to select the interface to be used in the CT Analyzer settings before connecting the
CT Analyzer to a computer. The CT Analyzer will only communicate via the selected interface. It will not
be recognized by the computer if the CT Analyzer settings do not match the interface used for
connection.
