The D360 8 Channel Patient Amplifier 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 and intended for electroencephalography (EEG), electromyography (EMG) and evoked-potential (EP) applications in a research or clinical environment. The D360 features versatile high and low pass filter options as well as a maximum gain of x3,000,000. The system comprises a main amplifier unit, a remote active head-box and dedicated Windows-compatible control software, the latest version of which can be downloaded below.
Multiple D360 amplifier systems may be connected to a single PC allowing multiples of 8 channels to be controlled by one PC system. Electrode connection is via touch-proof 1.5mm (DIN 42 802) sockets on the headbox and signal output to your chosen acquisition device is possible either through the eight BNC connectors on the front panel or a pair of “D” connectors at the rear of the main unit. Because the Windows compatible D360 Control Software can run in parallel with your data acquisition program, adjustments to the amplifier settings or tasks such as impedance checking and de-blocking can be made while still monitoring data collection.
Among the features included in the D360 are electrode impedance checking and de-block. Impedance checking can be activated from the headstage or control software and impedances levels are indicated in the software or via LEDs conveniently located on the headstage. Thresholds for the impedance levels are fully customisable by the user. The de-block facility can also be accessed via the software or headstage and allows the input circuitry to be stabilised more quickly following electrode placement or movement. D360 Amplifiers now include an external de-block BNC input, which allows the operator to remotely “gate” the de-block function of the amplifier with a TTL-high command. This can be useful for D360 operators who need the amplifier to detect responses with short latency, following a magnetic stimulus pulse. De-blocking while the stimulus is delivered can enhance the recovery time of the amplifier circuitry.
Importantly, the D360 has analogue signal outputs making it compatible with the majority of commercially available data acquisition systems, so users are not restricted to any particular acquisition and analysis software.

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.
The latest version of the software can be downloaded from the D360 Software page of this website.
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.
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.
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.
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.
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.
