Acroname's USB to serial adapter uses the industry leading FTDI chipset to bridge from USB to UART. It also provides a 5V output rail and signal level. It is compatible with slave devices which use 3.3V signal levels, as long as they are 5V tolerant. The device is fully powered from the USB bus. Driver support is available for Windows, Mac OS X and Linux at baudrates from 300bps to 3Mbps.
UART Tx/Rx pins are clearly labeled with direction arrows to eliminate confusion of data direction.
Old versions of the S27 are labeled with STX and SRX. These refer to the direction of the slave device serial direction. I.e. STX is for bits going from the slave device to the USB host; SRX is for bits going from the USB host to the slave device.

The USBHub2x4 is a 4-port software-programmable 480Mbps (USB 2.0) hub that is designed for demanding industrial environments where advanced control and monitoring of USB ports is required. This is very useful in testing or development environments where standard “always-on” behavior of a consumer-grade USB hub is not desirable.
