DEWE-NET
High-speed data acquisition for laptops or workstations via Ethernet
General facts:
- 1 GBit Ethernet connectivity to laptops and workstations
- Online data transfer or local storing
- Reliability
Data storage on instrument and remote computer
If LAN fails, data are stored locally and retrieved as soon as the network connection is back. - Up to 100 metres connection without hub
- Fast sampling rates up to 1 MS/s per channel
- Various models with up to 64 channels available
- Fully isolated or differential signal conditioning modules
- No software licence required for customers' computer, use different computers without any troubles
- No device driver installation needed on customers' computer
Single DEWE-NET instrument attached to a single computer
The instrument usually is fully remote controlled by YOUR computer. That means that the remote computer 100 % controls the DEWE-NET instrument and e.g. starts storing. For live data view all or a selection of activated channels are transferred to the remote computer. Data can be stored on the NET instrument and on the remote computer. The instrument keeps acquiring and storing data if the remote computer is disconnected. Of course the remote computer can be reconnected at any time and take full control of the instrument.
Multiple DEWE-NET instruments attached to a single computer
Mainly this mode is used in case of distributed systems, e.g. in long trains or on huge bridges.
A second good reason to use this mode is when the data rates are too high for a single instrument. The disk storing rate of different instruments ranges from 40 MS/s to 80 MS/s.
Example: To store 64 channels, 16 bit resolution at 1 MS/s per channel results in 128 MB of data per second which is too much of a single instrument. The solution is using two 32 channel DEWE-NET instruments and store 64 MB/s in each.
In such configuration all instruments must be synchronized to each other. There are multiple choices:
Of course multiple computers can connect to the network in a "view" mode.

- Synchronization cable (limited length, depending on sampling rate and A/D technology)
- IRIG time
- GPS time
- NTP (Network Time Protocol)
