6 The Serial Interface
By means of the serial interface and a suitable electrically isolated interface adapter (GRS3100, GRS3105 or
USB3100) the device can be connected to a computer for data transfer.
With the GRS3105 up to 5 devices of the GMH3xxx- series can be connected to one interface (see also
manual of GRS3105).
To avoid transmission errors, there are several security checks implemented e.g. CRC.
The following standard software packages are available:
ƒ
EBS9M : 9-channel software to display the measuring values
ƒ EASYCONTROL : Universal multi channel software (EASYBUS-, RS485-, or GMH3000- operation
possible) for real-time recording and presentation of measuring data of one GMH3xxx
device in the ACCESS®-data base format
In case you want to develop your own software we offer a GMH3000-development package including:
•
a universally applicable Windows functions library ('GMH3000.DLL') with documentation that can be used
by the most programming languages.
•
Programming examples Visual Basic 4.0, Testpoint (Keithley Windows measuring software)
Note: The measuring and display range values read back from the interface are always in the
selected measurement unit (mbar, bar...)!
