7 Input and Output Connectors
7.1 Power In
This information is provided for reference only. Use the recommended Plexon power supply and
cable to power the stimulator. The power input connector is a standard 9-pin circular mini DIN
connector. The stimulator operates from ±5V and ±15V power supplies.
7.2 Digital In
Each channel in the stimulator has a dedicated digital input (DI) that can initiate stimulation on that
channel. See sections 5.11 and 6.8. The inputs are TTL compatible.
7.3 USB 2.0
The stimulator has a mini type B USB 2.0 receptacle for communications with the host computer.
The USB receptacle on the stimulator is connected to digital IO ground. The USB connector on the
host computer is typically connected to the AC wall outlet ground. Therefore, the USB cable
typically connects the digital IO ground on the stimulator to the AC wall outlet ground.
