XPort Pro Block Diagram

The following drawing is a block diagram of the XPort Pro showing the relationships
of the components.

PCB Interface

The XPort Pro has a serial port compatible with data rates up to 921600 bps. The
serial signals (pins 4–8) are 3.3V CMOS logic level. The serial interface pins include
+3.3V, ground, and reset. The serial signals connect to an internal UART driven at
3.3V. For applications requiring an external cable running with RS-232 or RS422/485
voltage levels, the XPort Pro must interface to a serial transceiver chip. We supply an
RS-232 transceiver on the XPort Universal Demo Board for this purpose.
Note: The standard baud rate of 460800 bps is not supported.
