Not Connected in software
It is normal behavior that as long as the Neurobit settings window is open, the software 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 (or unpack Runtime files to software manually).
- If unable to change device, run Neurobit setup file again.
- Make sure at least channel A is enabled.
- Turn off Optima.
- Turn on again.
- Press panic button.
Try the following steps:
- Try a different USB cable
- Unpack Runtime files files to the C:\Program Files (x86)\BioExplorer or C:\Brain-Trainer for BioEra 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)
- (for BioExplorer- Be sure you are using the current version.)
- If using a USB hub or extender, connect directly to computer's USB port instead.
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).
Device turns off right after attempting to turn it on
- Has anything happened since the last use that could be related to the problem? For example the device fell or change of computer?
- Does the situation look the same for another USB port of the computer?
Could you please try update of the device firmware, as described below?
- Download the latest firmware file from the website http://www.neurobitsystems.com/download/Neurobit_Optima_Plus-firmware.htm to any convenient folder.
- Run software (BioExplorer/BioEra), open the device settings window and click the "Device services" button on the General Tab.
- Click the Browse button and select the downloaded nop2_4.bin file (in the folder, where you has stored it).
- Press the on/off button of the device and do not release it until the signal lamp lights red (it takes about 10 sec.)
- Click the Upload button in the loader window and wait until the process ends. If there is a message confirming successful firmware update, click OK.
- If the device remains on, turn it off, and than try to turn it on in a while.
- 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 Microsoft USB View 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. If using a USB hub or extender, connect directly to the computer instead.
- Try another USB cable.
- Try another Optima device
"The file includes configuration for inadequate device model."
The causes we see for this are:
User did not select correct device (Optima+ 4 USB)
User cannot select correct device because BioExplorer's installation wrote over the most current driver files from the Neurobit setup. Run the Neurobit setup again.
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.
