RS232 SERIAL INTERFACE
The calibrator may send data logging information to an IBM PC or compatible
computer by connecting the unit and the PC via an RS232 cable, and installing
the "Calsoft" software. Contact your supplier for details.
Ensure that there is a connection made before the calibrator is switched
on.
The RS232 cable must be fitted to both the unit and the PC before either unit is
powered up, otherwise, data integrity cannot be guaranteed. Once the cable is
fitted, it does not matter which unit is powered up first.
