The Serial Interface

All measuring and setting data of the unit can be read and/or changed by means of the serial interface and a suitable
electrically isolated interface adapter (GRS3100 or GRS3105). In order to avoid transmission errors, there are several
security checks implemented.
The following standard software packages are available for data transfer:
-EBS9M
-EASYCONTROL:
In case you want to develop your own software we offer aGMH3000-development package including
- a universally applicable 32bit Windows functions library ('GMH3000.DLL') with documentation that can be used by all
'serious' programming languages.
- Programming examples Visual Basic 4.0, Testpoint (Keithley Windows measuring software)
The following interface functions will be supported:
