When I hook the ActiView batterybox and turn on the amplifier the POWER / CM in range / low battery blink once, then turns off. The battery’s light glows green. The screen will read:

Error 5000 occured at No Incoming Data
Possible reason(s):
ADC-box power is off
or
Optical fiber is disconnected ...

Hi Guys,

We've been recording ERPs using Presentation. New trigger codes show up ever so often. It's puzzling.

Here is one coding system we have:

1
2
100
200
9
10

Sometimes, these codes show up:

110
91

Our programmer says that, for some reason, codes are being added together or subtracted ...

When I hook the ActiView batterybox to the amplifier the POWER / CM in range / low battery blink 3 times very quickly. The amplifier's POWER button glows for a quick moment, then the SHUTDOWN light stays on.

Then the software throws this error:

Error 5000 occured at No Incoming Data
Possible ...

I was recently approach by an institution that is designing a study in which it records a participant's voice, alters it's pitch, and then replays it back to the participant all in real-time. Each of these events ought to be coded and acquired by ActiView along with ERP data.

One line of thinking ...

I've been running pilots over the past few weeks and have run into a persistent problem.

When I record data from our 64 10-20 set up, the red line that scrolls across the screen always scrolls slower than when I don't record data. So much so that the responses a pilot participant makes is slightly ...

Thanks for the quick response.

I've also run into another problem that may have to do with Presentation + Biosemi set up, but perhaps not.

We use a mouse as our response box. Participants press the left or right mouse button depending on what they see on a screen. We use a 64 electrode set up to ...

I would like to know if there is a way to have ActiView begin saving data automatically once the stimulus in Presentation begins.

For example, if I have two computers. One computer runs Presentation. The other runs ACTIVIEW. If press the 'R' key on the keyboard to activate the stimulus on ...
