Dear colleagues,

We recently purchased a cable to synchronise the different signals from the Biodex System 3 isokinetic through a PowerLab 8/35 DAQ and LabChart software (ADInstruments). After thorough testing, we have not been able to see how the different variables are changing in the software (seems like the cable is working as we can see the signal in the channels). Please, find in the following link the information the company followed to build the cable (

We contacted Biodex (USA and Spanish providers) and they told us that it was necessary to have a tool installed on the computer called Analog Signal Access Interface (ASA Utility) to change the scaling factors ( However, they told us that everything related to the System 3 model was discontinued and they could not provide us with this software.

We would like to kindly request, if possible, if you could share with us a digital copy of the installation file of the ASA Utility. If you think this is not the problem, we would like to ask for your opinion on this topic as it would be of great help.

Thank you very much for the attention and help!
