2 Hardware

The CereStim R96 hardware is composed of one main board and at least one current generator

module. Currently, the system can hold up to 16 current modules. Each current module is

connected to each output channel (96), so that the number of channels is independent of the

number of modules. Systems containing multiple modules (2 or more) are capable of generating

simultaneous stimuli, where N modules allow N stimuli at the same precise time. This allows the

CereStim R96 to produce up to 16 simultaneous stimuli.

2.1 CereStim R96 Front Panel

The CereStim R96 Front Panel interfaces the PC with the CereStim R96 main board and its attached

current modules. CereStim R96 configuration is accomplished using the Stim Manager program

described in Section 3.

Power Supply Connector (1): The CereStim R96 is capable of being powered through an external,

medical grade power supply that is included as part of the CereStim R96 packaging. The green LED

labelled ‘Power’ will light up when the external power supply is connected to the unit. The power

cord is to be used for mains disconnection.

On/Off Switch (2): Use the on/off switch to turn on the CereStim R96. The green LED labelled ‘On’

will illuminate when the unit is turned on.

LED Indicators (3): The green LEDs labelled ‘On’ and ‘Power’ illuminate when the CereStim R96 unit

is turned on and powered through the external power supply. The ‘Low’ and ‘Charged’ LEDs are

non-functional in the current version of the CereStim R96. The ‘Status’ LED illuminates during

activity on the USB port to indicate communication between the CereStim R96 and PC.

USB Port (4): The CereStim R96 is programmed through commands sent via a USB A-B cable

connected between the USB port on the CereStim R96 and a USB port on the PC. The ‘Status’ LED

illuminates during activity on the USB port.

RS-232 Isolated Port (5): This feature has not been implemented in the current version of the

CereStim R96. The RS-232 isolated port is intended to provide hardware-hardware communication

in future firmware updates of the device.
