White Rabbit Switch - WRS
3.5 USB Connections
The WRS has three different USB ports used to communicate/monitorize through a PC.
• Management Mini-USB (B) port - #4
• FPGA Mini-USB (B) UART - #17
• ARM Mini-USB (B) UART - #18
Once the device has been correctly started up (Status LED is green), it is recommended
to use the USB management port to connect to the device instead of the ARM-UART. The
ARM-UART is usually employed during development and monitoring because the kernel and
daemons messages are sent to this console.
3.6 RS232 Management Port
RS232 is used as receiver port for GPS receiver.
