KiDAU Classic
Type K3881C...
On-Board Adapter
The KiDAU Classic Type K3881C... is a modular designed
on-board adapter for the nxt32 data acquisition module
Type K3870A. It consists of three mechanically independent
modules:
• Sensor Distribution (SD) Panel
• nxt32 data acquisition module Type K3870A
• KiDAU Classic casing

Description
A KiDAU Classic System has 32 analog and 16 digital
inputs. The application of different connectors as well as pin
assignments for the 32 analog inputs will be mapped by means
of different SD-panels.
K3881C_003-115e-06.16
Each analog channel comprises a programmable input
amplifier, bridge excitation circuit, low pass filter and 16 Bits
A/D converter. The amplifier precision is better than 0,1 %
and the input impedance above 10 MΩ. The gain values can
be programmed from 0,5 ... 10 000. An internal reference
voltage is used for precise control of the amplifier setting,
which is achieved via software loop.
The bridge excitation voltage is programmable separately
for each channel. Bridge completion for half bridges can be
switched internally. All current sensors may be supplied, a short
circuit limitation is provided. In contrast to former designs,
the input low-pass filter is designed only as an adaptive antialiasing filter. All necessary filtering according to SAE filter
classes has to be done in the evaluation and analysis software
or the ChrashDesigner. Each channel of the KiDAU has its
own A/D converter with a 16 Bits resolution. Thus all channels

are sampled simultaneously, ensuring that no time lack occurs
between different channels. The maximum sampling rate
is 100 kHz for the KiDAU. Each channel of the KiDAU has
a dedicated D/A converter of its own for compensation of
the offset voltage. Neither potentiometers nor trimmers nor
mechanical switches are used inside the device. All adjustments
are implemented by software, automatically or by command.
Application
The KiDAU Classic Type K3881C... is a very reliable data
acquisition system designed for daily crash testing under harsh
conditions.
The KiDAU can store data for a 100 s cycle at a sampling
rate of 100 kHz which allows the user to start recording data
before the vehicle or sled is actually started. This ensures that
the measuring system works correctly and prevents data loss.
The trigger point is registered and recorded as in previous
systems. Once a valid trigger point is stored in the KiDAU data
memory, the user can only select the actual measured data
for transfer to a PC, and it is no longer necessary to read out
the complete system memory. The KiDAU is designed with a
trigger input and output for synchronization with other units.
The first analog channel, two digital channels and a remote
signal (software trigger) can be selected for triggering.
The trigger threshold and trigger criterion can be freely
selected for the first analog channel. Batteries are no longer
needed to retain the data because flash-EEPROMs are used
for the memory. The data remain available for many years!
The KiDAU system uses an internal Lion battery designed to
run the complete system, including all connected sensors, for
up to 10 minutes. External power supply using trailing cables
is of course still possible. The size of the memory available
in the KiDAU demands fast interfaces for data transfer. The
standard interface for data transfer is 100BaseTx Ethernet with
TCP/IP protocol. This interface supports high transfer rates
and ensures perfect operation even when long umbilical cables
are used. Both commands and data are transferred via this
interface.
