The D360 is a computer-controlled 8-channel patient-isolated AC-coupled biological amplifier and analogue filter system, CE marked according to the European Medical Device Directive. The system comprises a main amplifier unit, a remote active head-box and dedicated Windows compatible control software.
Multiple D360 systems can be connected to a single computer (via a single serial port) to allow multiples of 8 channels to be controlled through a single software interface.
The D360 is ideally suited to research or diagnostic use, as an electroencephalography amplifier (EEG), electromyography amplifier (EMG) or evoked potential amplifier (EP).
Analogue signal outputs mean that the D360 can be used with the majority of commercially available data acquisition systems, so you aren’t restricted to any particular data acquisition and analysis software.
- Individual or grouped control of the gain and filtering characteristics of amplifier channels.
- Impedance checking feature allows tri-colour LEDs to indicate problems with any electrodes.
- Notch filter (factory set to 50Hz or 60Hz). Large range of low-cut and high-cut band-pass filter settings.
- Overall gain of x100 to x3,000,000 with outputs at the front (BNC) or rear (D-type) of the main unit.
- Includes software control of amplifier settings.
- Typically used as an multi-channel EEG amplifier or multi-channel EMG amplifier.
- Compatible with our D175 Electrode resistance meter.
- Support for control by CED Signal and Spike2 software (32bit CED installations only).
- Windows XP (SP2), Vista, Win7 and Win8.1 (32 bit and 64 bit) compatible control software included.
1. I am using the D360 Amplifier but I do not have a users manual for it – Is it possible to obtain a copy from Digitimer?
Yes, the users manual is available as a PDF embedded in the D360 Control Software. Just click on “Help” within the menu bar and you can open a copy and save it for future reference..
2. I want to obtain the latest version of the D360 control software, where can I download it?
The latest version of the software can be downloaded from the D360 Software page of this website.
3. I have recently started using a mixture of recording electrode types and now I am having difficulty seeing the resultant EEG activity. It appears as if the amplifier is blocked, as the de-block function momentarily brings the signal back. What is happening?
It is possible that the problem is due to the difference in materials that the electrodes are constructed from. The D360 circuitry is designed for electrodes which are at similar potentials (i.e an input offset different by no more than 100mV). If you use a mixture of electrodes types it is possible that the input offset would exceed 100mV and the amplifier would not be able to compensate for this difference in potential. We would recommend that you determine the potentials the electrodes are at to see if that could be an explanation and consider reverting back to electrodes constructed from the same materials.
4. I want to upgrade to the most recent D360 Control Software, but I am not sure it is compatible with my amplifier, how do I tell?
The most up to date version of the software is available here, however, it must not be used with D360 amplifiers of serial numbers lower than 51, unless they have been specifically modified by Digitimer to accept this version. Please note that the current version of the D360 software is NOT Windows 95 or 98 compatible.
5. I want to use my D360 with a laptop computer, but the computer does not have a serial port, what can I do?
Digitimer have successfully tested and can supply a type of USB to serial port adaptor which allows the D360 to be run via a USB port. However, not all USB to serial port adaptors are compatible, so please contact us further information.
6. I have installed a USB/Serial adaptor supplied by Digitimer, but my computer is failing to communicate with the D360. Can you help?
Typically this problem is due to the USB/serial adaptor not being recognized by Windows or the assigned COM port being to high. Please check within the Device Manager that it is installed correctly and if not, reinstall it using the VCP driver software from the FTDI website. It should also be noted that the Digitimer D360 Control software needed to be installed using an administrator account.
If the installation of the software and adaptor has completed successfully, but the D360 is still not recognised by the computer, check that the COM port assigned to the USB Serial adaptor is lower than 10. COM port values higher than 10 are not visible to the D360. Changes to the COM port assignment can be made within the “USB Serial Adaptor” section of the Windows Device Manager.
7. I have enabled the “D360 signal conditioner” feature in the CED software, but should I also run the D360 Client Software?
The latest versions of CED Spike2 and Signal software packages now have the ability to control the gain and filter settings of the D360 amplifier as well as check the D360 channel impedance values. This means that gain and filter settings are stored alongside the recorded data and changes can be made without having to leave the acquisition software. However, it should be noted that if you run the D360 Client software simultaneously, both it and the CED software will have access to make changes to amplifier settings and this could become confusing. We therefore suggest that Signal and Spike2 users do not run the D360 Client Software and make all changes to D360 settings within the CED software.
