Acquisition stops, error 5000.
 
If you get an Error 5000 when starting the aquisition, then several things can be checked:
1) Unpug and again plug in the USB cable of the BioSemi USB Receiver.
The USB Receiver will be shown in the Device Manager like this and will make this sound.
2) Check if the AD-box is at Speedmode 4.
3) Check if there is dirt in the fiber optic inputs or on the fiber optic connector.
4) Try another USB port on your PC.
5)

Check the Optic Link LED on the USB Receiver.
If this LED is off, then either the Receiver is not connected correctly to the PC, or the optical link is defect.

6) When pressing Start in ActiView, the USB Link LED should blink.
If this LED does not blinks when starting the acquisition, then this is because the USB Receiver is not detected by the PC:
- Unpug and again plug in the USB cable of the BioSemi USB Receiver
- Check the drivers
  ActiView Error codes:
5000 No incomming data (see this page)
5001 Ring Buffer Overflow (computer too slow)
5002 Sync Error (bad optical connection, critical with Daisy Chain)
5003 End of File (selected size or time limit reached)
5004 No Jazz data (check eyetracker power)
5005 Jazz Packet Loss (check eyetracker optic fibers)

 

 

The AD-box shuts down or the acquisition stops. (Power LED on AD-box turns off)
 

Inside the AD-box there are several safety circuits constantly monitoring whether all currents flowing are within the safety limits. When the AD-box detects an unsafe situation, then all powers inside the AD-box and all powers going to the active electrode sets will be shut-down. All 3 LED's on the front of the AD-box will turn off (the battery box should be working OK and the green LED on the battery box should be on)
If the gel bridge is present at the SCSI connectors on the AD-box, then the shutdown can happen even without any electrode set being inserted into the AD-box.
If the gel bridge is at the SCSI connectors of a P32 electrode set, then a shutdown will happen when this electrode set will be plugged into or is already plugged into the AD-box.

When a situation like this occurs (AD-box shuts down and all 3 LED's on the AD-box suddenly turn off) then this is because the safety circuit detected a to high leakage current going thru the guarding circuit. This is caused by gel residue inside 1 or more SCSI connectors on the AD-box or gel remains inside the SCSI connector of a P32 electrode set.
The procedure is to first visually inspect the SCSI connectors (preferable with magnifying glasses) and then try to remove the gel.
This can be done with alcohol or distilled water and a cotton cloth. Gel residue inside the SCSI connectors of the P32 electrode sets can also be removed with cotton sticks.

When a SCSI connector on the top of the AD-box is damaged or the gel can not be removes successfully, then we can replace the TOP PCB of the AD-box. The costs for replacing the TOP PCB is 350 Euro (excluding shipping costs). Replacing the TOP PCB takes 1-2 working days.
