8 Output / External Supply
The device has a serial output (for interface converter USB 5100). If the output is not needed, it is strongly
recommended to deactivate it (Out oFF) to lower power consumption. This increases battery life time.
If the device is used together with interface adapter USB 5100 the device is supplied from the interface.
Pin assignment:
4: external 5V, 50mA
3: GND
2: TxD/RxD (3.3V Logic)
1: not used
Only suitable adaptor cables are
permitted (accessories)!
The device can be connected to a USB interface of a PC by the electrically isolated interface converter
USB 5100 (accessory). The data is transmitted binary-coded and protected against transmission errors by
complex safety mechanism (CRC).
The following standard software packages are available:
GSOFT3050
:
Operating and evaluation software for the integrated logger function
EBS20M / -60M
:
20-/60-channel software for measuring value display
GMHKonfig
:
Configuration Software (for free on internet)
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, can be used
by all ‘established’ programming languages, suitable for:
Windows XP™, Windows Vista™, Windows 7™
Programming examples
Visual Basic
™, Delphi 1.0™, Testpoint™ etc.
The device has 2 channels:
-
channel 1: actual-value-channel pH, mV or rH and base address
-
channel 2: temperature value
