It is normal behavior that as long as the Neurobit settings window is open, BioExplorer is not connected to the Optima.
Check that you connected the Optima cable and turned it on.
Check Neurobit Optima settings.
Device Model (e.g. Neurobit Optima+ 4 USB)
- If correct device is not shown in Device model, select correct one.
- If unable to change device, run Neurobit setup file again.
Try the following steps:
- Unpack Runtime files files to the BioExplorer folder manually.
- Run the CDM21228_Setup (D2XX Driver Windows 64-bit setup executable) Right-click and run as administrator (may be found in Brain-Trainer\Help folder)
- Be sure you are using the current version of BioExplorer.
Notes: Just as the device is turned on there should be a sound from the computer confirming that the device has been detected (and if necessary, driver should install automatically in most systems). After that there should be "USB Serial Converter" device in "Universal Serial Bus Controllers" section in Windows Device Manager.
- If under "Other devices" the Optima is listed with a yellow warning symbol, do a manual installation of the FTDI chip driver (CDM21228_Setup).
- Is the device's power indicator green?
- Is the link indicator green?
- What Windows version do you use?
For further testing please install the USB View tool from the FTDI website:
https://www.ftdichip.com/Support/Utilities.htm#MicrosoftUSBView With the turned on Optima run this tool and see if there is USB Serial Converter in the left column. If so, select it and see the right column. Especially, under the "iProduct" line there should be the string "Neurobit Optima*", as shown in the attachment.
If there is no such string, the device is not detected in the system, probably due to some hardware problem.
In this case please:
- Check if the micro USB plug is inserted into full depth of the ISOL USB socket?
- Try another USB port of the computer.
- Try another USB cable.
- Try another Optima device
No EEG signal with Electro-Cap and independent references (No internal connection).
The Electro-Cap, when enabled in the Cap tab, has only internal (linked) connection for references on the Optima. In the case that you want independent references you will need to keep the cap ear wires unused and use tin ear clip electrodes that connect to the Optima's reference (-) ports to override the cap. If you do not have ear clip electrodes, you can try quick insert electrodes connected to the hole in the ear clips to see if this gives a stable connection that can be used for training.
