Hi Jarek and BioEra community,
I'm using BE with my J&J C2+. 2 questions about configuring it:
1. How do I control the sample rate?
Is it simply a matter of putting a re-sample object after the source? If so what do I put for the input sample rate?
2. The J&J device comes with a notch filter - I believe it's a software thing, part of the device driver. You can set it to 50 Hz or 60 Hz. 60 is the default. As I'm in Europe I would like to set it to 50Hz. Is there a way to do that?

Many thanks and best wishes,

Glyn Blackett

Glyn,

1.C2+ has a very flexible way to control channels, it is configured in a text file: Device.ini which located is in main bioera folder. That is why there is not much to set inside the bioera object. It is possible to set Rate in there. After that you probably need to restart bioera, but it may be what you are looking for.

2. The device driver I got from J&J doesn't have option to set notch filter directly. So this question should be probably directed to J&J. Perhaps it is possible to set it somehow in the Device.ini file, but I don't know how to set 50Hz notch.

Thanks again.
I will approach J&J about the notch filter.
