Now 32 Channels of Electrical Stimulation
PlexStim™ Software 2.2 is now available online for the PlexStim Electrical Stimulator 2.0, Plexon’s electrically isolated, individually programmable, 16 channel, constant current stimulator system. The new release now enables up to 32 independent stimulation channels to be controlled via the PlexStim software development kit (SDK). To achieve 32 channels, researchers are now able to use two PlexStim 16 channel devices together.
PlexStim can generate arbitrary waveform patterns initiated from either the software interface or from externally triggered digital inputs with an unprecedented 30nA resolution and 1µsec temporal resolution. The graphical user interface (GUI) makes it easy to generate bi-phasic rectangular pulses and bursts of pulses repeated at specific rates. More complicated rectangular waveforms and non-rectangular arbitrary waveforms may be defined in and loaded from a simple text file.
Every stimulation pattern can be started and stopped either manually within the GUI, or with an external digital trigger (TTL). Complex stimulation patterns can be delivered in this way with precise timing based on different triggers. Each channel has a dedicated digital input that may be used in an edge triggered or level triggered (gated) mode to initiate stimulation with microsecond latency. Each channel also has a dedicated digital output signal to third party devices at the precise time when stimulation is occurring.
The actual current and voltage delivered to each electrode can be conveniently monitored on a per-channel basis with stimulation currents defined with 16-bit precision up to ±1mA and delivered with ±10V compliance.

Did you know . . . Where to Find Notes About Software Updates?
Plexon software applications include a Change Log that details new features, improvements and bug fixes included in the current and previous software releases. This Change Log is included in the installation folder of the software, and on the Plexon website as a separate link in the same location as the installer. We include as much information on software releases as we can fit into the newsletter with every release, but often the list of new features and improvements is too long to include in its entirety. For the complete list, see the corresponding Change Log.
Additionally, the installer for the OmniPlex® Neural Data Acquisition System also includes Release Notes that go into even more details about the new features and improvements in the current and previous releases of the software. It will often include screenshots and guides to using new features, and other information that has not made it into the manual yet. The Release Notes are only included in the installer for the OmniPlex System and are not found separately on the website.
For more information about software updates, change logs or release notes, contact firstname.lastname@example.org.
