6.4 Internal Data Transfer
The communication between the PC and the measuring probe takes place serially by means of COM port emulation.
Therefore, it is easy to link the measurement to your own software. (Programming knowledge presupposed). For the
USB UART FTDI 232 used, drivers are available for Linux, MAC or PDAs. Further information is available on www.
ftdichip.com.
The interface works on a data rate of 4800 Baud, 8 data bits, no parity and one stop-bit.
6.5 Software PCLOG
6.5.1 Visualisation and Documentation
The most important feature of the software is the
graphic visualisation of all measured and recorded
channels as a y/t chart (online scriber function). By
means of Click & Drag, the window section can be
enlarged and the time or temperature axis can be
scaled as required. Multiple recording windows can be
opened simultaneously. Moreover, multiple physical
parameters can be presented in each window in which
the axis denition, colour scheme, channel description,
icons and many other options can be congured. The
clipboard serves as the export function for transfer of the
measured data series into a spreadsheet calculation with
the help of user friendly wizards. All tables and graphic
presentations can be plotted or printed in colour.
