If none of both is needed, we suggest to switch the output off, because battery life then is extended.
8.1 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.
With the GRS 3105 up to 5 devices of the GMH3xxx- series can be connected to one interface (see also
manual of GRS 3105). As a precondition the base addresses of all devices must not be identical, make sure
to configure the base addresses accordingly (refer menu point “Adr.” in chapter 1 “Configuration“).
To avoid transmission errors, there are several security checks implemented e.g. CRC.
The following standard software packages are available:
GSOFT3050
:
Operation and read out of logger function, data display in diagrams and tables
GMHKonfig
:
Software for a comfortable editing of the device (e.g. Material selection…)
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 ('GMH3000.DLL') with documentation that can be used
by the most programming languages. Suitable for Windows XP™, Windows Vista™, Windows 7™
Programming examples Visual Basic 4.0™, Delphi 1.0™, Testpoint™
