4 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 GRS3100, GRS3105 or
USB3100). 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
!
EBS9M
:
9-channel software to display the measuring values
!
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)
In addition to the operation at a PC the device can be operated with the
GAM3000-device
, to use the alarm
function for simple supervision and controlling applications. Just connect a GAM3000 to the interface,
activate the alarm function of the GMH and the relays output is operating.
The device has 3 channels:
-
Channel 1: current measuring value (base address)
-
Channel 2: min peak (p.r.t. chapter 3)
-
Channel 3: max peak (p.r.t. chapter 3)
Note:
The measuring-/ alarm- and display range values read back from the interface are always
in the selected measurement unit (mbar, bar...)!
