D-2/16 - Mobile mini DAT recorder
A small device for extremely hard applications Smallest 16 channel DAT recorder of the world for record and playback of analog signals up to 16 kHz per channel!

The D-2/16 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-2/16 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 20 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-2/16. For more information contact our sales office
