DI Polarity Negative
If DI Polarity is set to Negative and the device is in Edge triggered mode, the controller responds to
falling edges on the Start and Stop digital input pins. In Level triggered mode, the controller starts
on a falling edge and stops on a rising edge of the Start digital input. Note that changing polarity
while a channel is loaded may cause it to start depending on the state of the digital input. If a digital
input is at 5V and you polarity is changed from negative to positive, stimulation will start.

File Load Settings / File Save Settings
The settings for all channels can be saved to a user named file for future use by clicking the Save
icon or by selecting Save from the File menu. These configuration files have an extension of “.ops”.
The default values of the parameters can be restored by selecting File – Restore Factory Settings.
You can also go to Window – Layout – Reset to Default Layout to set the windows of the GUI back to
their default state.

View
When one controller is connected to the computer, there will be three choices under the View menu
bar: Controller 1, Patterns 1, and Messages. Each additional controller that is connected to the
computer will have an additional window for Controller and Patterns. The number corresponds to
the LED number that is illuminated under “Device” on the end panel of the controller.

Window
You can adjust the appearance of the Radiant GUI in the same ways that other Plexon software
packages can be adjusted. Each window can be resized, docked, undocked, or hidden completely.
Once you have setup the GUI to display how you want it to, you can save the settings under Window
– Layout – Save as Layout 1. You can then apply this layout if your GUI setup is changed. You can
also return to the default layout at any time.
