CONFIGURATION

The MCP2200 is configured by writing special

commands using the HID interface. Configuration can

be achieved using the configuration utility provided by

Microchip. Alternatively, a custom utility can be

developed by using the DLL available on the MCP2200

product page.

2.1

Configuration Utility

A configuration utility is provided by Microchip to allow

the user to configure the MCP2200 to custom defaults.

The Configuration Utility (Figure 2-1) connects to the

device’s HID interface where all of the configurable

features can be set.

2.2

Serial String

The MCP2200 is supplied from the factory with a

serialized USB serial string.
