USB-PIO

The Universal Serial Bus – Parallel Input Output (USB-PIO) has been designed specifically for use with the  M470. The USB-PIO allows external devices, such as a low voltage lamp or LED, to be switched directly from the M470 software.

The USB-PIO can be used to control up to 4 different channels individually or collectively in a standalone experiment, in a sequenced experiment, or in the Modular Map Experiment (MME). The MME is an SECM based experiment designed specifically for use with the USB-PIO, and is available with the M470 scanning electrochemical workstation. Using the MME researchers can switch or read from external devices at each individual x-y point, and apply multiple biases at a single point in the area scan.

The USB-PIO can interface directly to user supplied cables using the DB25 pin female connector, or through the supplied breakout PCB. The USB-PIO interfaces to the user’s PC through USB connection, which also acts as the power supply.

The USB-PIO for the M470 Scanning Electrochemical Workstation can be used for a variety of practical applications including:

• The investigation of the effect of light on a living plant
• The investigation of the effect of light on dye sensitized solar cells

The USB-PIO is supplied with the USB-PIO, a breakout PCB, and the necessary parallel and USB cables.
