KT MicroDAU Onboard DAS

MicroDAU Description
The Flex PLI leg can be configured to use a KT MicroDau onboard data acquisition system. This
configuration is a 12 channel system with battery backup and USB communication. The design allows
any existing leg to have a MicroDAU iDummy configuration with minimal additional parts. MicroDAU
modules are designed to replace the knee covers over each of the four knee cavities with three to six
channels in each cavity. A lithium battery is provided for approximately 30 minutes of standalone
operation.

The MicroDAU configured leg requires 5.0v input at 600mA during operation using USB communication
through the standard Kistler Crash Designer software. For detailed operation of the MicroDAU system
and Crash Designer software please refer to Kistler documentation.
The MicroDAU system consists of 4 modules. The battery module (133-5713) contains the battery,
charger, USB hub, the leg power/comm exit cable and communication to the rest of the modules. The
battery is lithium/manganese chemistry and provides power for 30 minutes of operation. Three
additional sensor modules (133-5710, 133-5711 and 133-5712) contain 3 or 6 data acquisition channels.
Each module provides connectors for single channels, such as potentiometers or three channels such as
femur or tibia moments. Modules 133-5711 and 133-5712 also provide power/comm inputs and outputs
while module 133-5710 contains only power/comm inputs.
Modules are designed to be ‘daisy chained’ as shown in Figure 43. The battery module begins the
chain, with each module connected to next module. Module 133-5710 is the last module in the chain.
Clearance is provided under each module for power/comm and sensor cables. The clearance is tight due
to space restraints so care must be taken to assure cables are not overlapping or pinched during
assembly.
