Sessantequattro+ with Biodex 3 Inquiry

#1 · 29 Gennaio 2025, 19:54

My team and I are trying to collect force output by connecting our biodex 3 to the sessantequattro via this set up, yet we are still not seeing any signals. If anyone can see something wrong with our setup or can provide insight on what we should try doing in Settings, please let me know!

Good morning,

the hardware configuration seems to be correct. Could you clarify what you mean when you say you don’t see any signal?
Is the track completely missing, or is it present but showing no activity?

In the first case, you can simply configure the AUX channels in the Settings. Just select the AUX channel, choose "ISO-AUX" from the adapter list, and then configure the "AUX Force" as sensor (an image of the Settings is attached)
In the second case, it could just be a display scale issue

Let us know how it goes

Hi Valentina,

Thank you so much for the reply! The channel is there and we see a line. However, when a participant is pushing against the biodex, the force does not seem to be registered on otbiolab+ (the line does not change).

We have tried changing it to ISO-AUX and this did not resolve the issue.

If it is a scaling issue, what would you suggest? We have tried the + and - button on the side of the channel during visualization but still see no change in the force line when force is applied on the biodex.

We are also working with a Biodex 3 which is an older model. Could this be contributing to the problem?

Hello,

I believe this issue might be a bit tricky to investigate this way. I think it would be better to set up a call so we can review the setup and software configuration together. Feel free to email me at v.devitis@otbioelettronica.it, and I'll be happy to schedule a meeting at a time that works best for you!
