USB-to-UART Interface

The USB signals of this interface are converted to UART signals using a bridge chip, e.g.,

when you connect a PC or other remote station using a USB port. The remote computer

does not need a UART port.
The interface supports:



Data rates up to 4 Mbit/s



512-byte transmit buffer



512-byte receive buffer

See the MEN website for a service cable for USB:
