NeVib can cooperate with many data acquisition devices. Currently these devices are implemented:
Many Data Translation devices, i.e. DT8916, DT9834 and many more
RogaDAQ16
Dewetron DEWE50-USB2-16-Racks with DataTranslation acquisition device.
Sequoia FastTracer
VibDAQ4 VibDAQ 8
HBM MGCPlus
Acquisition device simulator (allows testing without acquisition hardware)
The acquisition can be parameterized by the file NECC.INI.
In section [TryToLoadDevice] it can be selected which devices can be used.
e.g.
DT = 1
RogaDAQ = 0
VibDAQ = 0
FastTracer = 0
HBM = 0
Simulator = 0
declares that only Data Translation devices will be chosen and all other devices are ignored.
16 analog channels, two counter-channels for frequency measurement.
3 channel USB vibration sensor with direct USB connector, power supply via USB, range of measurement 5 g (special devices also with two effective ranges of 2 g and 18 g)
Section NECC.INI: [NECC_Fasttracer]
Entry
Fullscale_g = 5
defines full scale of the FastTracer. Default: 5g
4 or 8 channel USB vibration sensor with direct USB connector.
The DataTranslation drivers are not included in the NeVib-Setup.
Some DT devices supported:
|
Name |
Number of channels |
|
DT9810 |
8 analogue channels with up to 25 kHz, one counter input for frequency measurement |
|
DT9816 |
6 analogue channels with up to 150 kHz, one counter input for frequency measurement |
|
DT9837 |
4 analogue channels with up to 105 kHz, one counter input for frequency measurement |
|
DT9834 |
16 (max 32) analogue channels with up to 500 kHz, 5 counter inputs for frequency measurement |
The DEWETRON preamplifier may be entered in NECC.INI as connector box:
[ConnectorBox]
# ConnectorBoxType = 0: No connector box
# ConnectorBoxType = 1: preamplifier DEWETRON DEWE-50-Rack
ConnectorBoxType = 1
Attention!
Because of the special handling of the USB connector of the DEWETRON devices please play attention to the following rules:
Please install all Dewetron drivers BEFORE you connect the device to the computer.
Please NEVER switch on or off a DEWETRON device while it is connected to the computer via USB.
Please disconnect the USB-connector of the DEWETRON device before shut down or restart your computer.
Please do not start NeVib after connecting your DEWETRON device to the computer before you have heard the DEWETRON start sound. This may take up to 20 seconds.
If you have further problems, please use another (better, shorter..) USB cable. There are USB-cables which do not fulfill USB 2.0 specifications and should only be used with USB 1 devices.
DAQP-CHARGE-A
DAQP-V
In addition the 5 counter inputs at the rear of the device CNT 0 .. CNT5 are supported.
The amplifier modules can be adjusted by using the DEWETRON software DEWESOFT and also by using the switches at the front of the module.
During the start of NeVib these adjustments are read from the module and will be used during measurement.
To read these adjustments the software has to have some informations about the connected Dewetron device. These informations are contained in file NECC.INI. This file has to be located in the current working directory.
If it is not possible to read the data via the COM-port defined in NECC.INI the setup data will be read from NECC.INI. Please pay attention that the definitions in NECC.INI are the same as in the DEWETRON device.
The file contains some sections.
Defines the COM-port for the software to connect to the device. This may be the COM-port in the DEWETRON device, which is provided as virtual COM-port via USB, or also a real COM-port, if the DEWETRON device is connected to the computer via RS232.
Example:
Port = 3
for COM3
Please note that the COM-port may change when the DEWETRON device is connected to another USB port. The port can be found in the device manager.
Section: Connections (COM and LPT)
entry: USB - Serial Port (COMx)
x means the number of the port ( e.g. COM3 for port 3).
The information about the slots are contained in the following sections::
defines the logic address of the slot.
