Interfaces
Communication interfaces such as USB port or EtherCAT or CANbus are available. The
device has 8 configurable analog outputs (±10 V and 4...20 mA among others). UART
interface serves to control the measuring amplifier via the Raspberry PI (not for versions with
EtherCat).
The interface protocol of USB and UART is identical and described in a separate
documentation (ba-gsvcom.pdf). Standardized fieldbus protocols EtherCAT and CANopen
reside in the lower protocol layers and a separate document describes the application layer
(ba-gsv8canopen.pdf and ba-gsv8ethercat_en.pdf).
Software
The Windows program BlueDAQ with graphical user interface and the console terminal
program BX8 terminal are suitable. A Windows function library (MEGSBX8w32.dll) with
commented C header is available for self-programming users and a LabVIEW library with
wrapper VIs for this DLL for programming with LabVIEW ©.
Features
There are 8 analog inputs available. They are individually configurable as:
Strain gauge input for full bridges in 4 and 6 wire technology or
Strain gauge input for half bridges or
Strain gauge input for quarter bridges 120 ohm, 350 ohm, 1k Ohm or
Single-ended input ±10 V or
Input for PT1000 temperature sensor
The strain gauge supply voltage is adjustable between 8.75 V, 5.00 V and 2.5 V, assigned to
input sensitivities 2 mV/V, 3.5 mV/V or 7 mV/V.
