11 The serial interface
By means of the serial interface and a suitable electrically isolated interface adapter (USB 3100, USB
3100 N, GRS 3100 or GRS 3105) the device can be connected to a computer for data transfer.
To avoid transmission errors, there are several security checks implemented e.g. CRC.
The following standard software packages are available:
GMHKonfig
:
Software for a comfortable editing of the device (freeware)
EBS 20M / 60M
:
20-/60-channel software to display the measuring values
In case you want to develop your own software we offer a
GMH3000-development package
including:
a universally applicable Windows functions library ('GMH3x32e.DLL') with documentation that can be
used by the most programming languages. Suitable for Windows XP™, Windows Vista™,
Windows 7™, Windows 8 / 8.1™, Windows 10™
Programming examples Visual Basic 4.0
™, Delphi 1.0™,
