MCP2200
2.0 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
The configuration utility provided by Microchip allows
the user to configure the MCP2200 to custom defaults.
The configuration utility (shown in 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.
TABLE 2-1: CONFIGURATION DESCRIPTIONS
Configuration Name Description
Vendor ID (0x04D8) The USB vendor identification assigned to Microchip by the USB consortium.
Product ID (0x00DF) Device ID assigned by Microchip. The device can be used “as-is”, or Microchip
can assign a custom PID by request.
Baud Rate Sets the UART baud rate using a list of primary baud rates. See the UART
section for details on setting non-primary baud rates.
IO Config Individually configures the I/O to inputs or outputs.
IO Default Individually configures the output default state for pins configured as outputs.
Tx/Rx LEDs Enables/disables the GP6 and GP7 pins to function as USB traffic indicators.
Pins are active low when configured as traffic indicators.
Hardware Flow Control Enables/disables CTS
and RTS flow control.
USBCFG Pin Enables/disables the GP1 pin as a USB configuration status indicator.
Suspend Pin Enables/disables the GP0 pin as a USB suspend status pin.
Invert Sense Enables/disables the UART lines states:
- Normal – Tx/Rx idle high; CTS
/RTS active low
- Inverted – Tx/Rx idle low; CTS/RTS active high
Manufacturer String USB manufacturer string.
Product String USB product string.
