D-2/4 - mobile mini DAT recorder
Smallest 4 channel DAT recorder of world
for record and playback form analog signals up to 16 kHz per channel in 2 channel mode. |
|
- Record and reproduce of 4 analog data
channels, voice, date, time and digital signals.
- Extremely small and ruggedized design and
therefore multiple application areas
- Usable in each position and therefore
especially suitable for extreme mobile applications
- Very resistant against shock and vibrations
- Extremely adaptable to various measuring
requests due to switchable number of channels and signal bandwidth
- Robust remote control box with bargraph
display
- Computer interface for on- and off-line Data
analysis (OPT.)
- Telemetry connection for computer interface
for on-line data analysis during mobile use (OPTION)
- Event-driven record commands
- Record commands by Remote Control
- Automatic test number recording
- Fast search run in both directions
- Power supply DC 10 ... 18 V or 18 ... 32V,
battery (OPTION), mains 220 V AC (OPTION)

The D-2/4 DAT Recorder is small and
powerful. The physical size has a major advantage over larger units. Due to the small
mechanical dimension it can be. This becomes apparent, whenever space or critical
positioning is the issue. Good examples are the cramped quarters of building and
earth-moving machines, cars and planes. The surveillance's and analysis is done On-line.
A telemetry output, connected to our RF telemetry TS/TE 2.5, transmits the data to a
computer. Concurrently, high redundancy recording of raw data takes place within the DAT.
With the aid of our REMUS Software all or single channels can be selected and/or
presented. The computer freed from the ''Data Logging" task can now be utilized for
analysis and presentation.
The ''Record Commands" can be controlled remotely. The "Record Procedure"
is started and terminated with the +5 V and 0 V levels respectively.
Sometimes, especially during long term measurements, continuous recording would be
impractical. In this case the ''Event-Driven" record control is a powerful tool.
Supporting this feature is one "Event Channel". Once an ."Event
Channel" is activated, a ''Record Procedure'' of approximately 1 minute is started.
This procedure includes the recording of the active event, time and test number.
The D-2/4 DAT can convert data from analog to digital and feed them into computer directly
without recording. For this operation the "Tape Bypass" function is used. Just
as in recording mode the analog data are filtered and digitized. The data are transferred
directly to the computer instead to tape.
This is independent upon the tape runs and records data or stays without recording.
In this mode the DAT recorder is used as PCM encoder for telemetry transmission.
Another feature is the pulse input DIG In/Out. With that feature any pulses with any
sampling relationship from 0 to 40 kHz can be recorded and reproduced. This input is very
suitable for PCM signals transmitted via RF telemetry. Data from PCM encoders, input
pulses from sensors for revolution or speed, or the recording of simple events are just a
few. Optionally an event multiplexer for 16 events is available.
These are some examples of the flexible use of our Data Recorder D-2/4. For more
