| In Linux on the device, ''ttyGS0'' and ''ttyGS2'' are symlinked to ''tty.usb0'' and ''tty.usb2'', respectively. ''tty.usb0'' is available as I/O for the GNSS software, and can be used the same as the two UARTs which are physically available as the serial ports accessible through the M12 connectors on the front of the unit. By default, the GNSS firmware uses ''usb0'' as SBP in/out, but it can be used for NMEA out, RTCM in, or RTCM out as well. ''ttyGS2''/''tty.usb2'' is in use, but I don't believe its use is configurable from the Swift Console. | In Linux on the device, ''ttyGS0'' and ''ttyGS2'' are symlinked to ''tty.usb0'' and ''tty.usb2'', respectively.

| | Note about this port: it does deliver power to the Piksi Multi, but I'm not sure if the rest of the Duro will work correctly. Usually in cases like this the Vcc line of the USB port is left disconnected, requiring the user to operate the device from a dedicated supply. I don't know if this was intentional or a mistake made when designing the Duro board. In my own testing, the Duro does work when powered from MicroUSB alone, pulling just shy of 5w in normal use. Ethernet and microSD work, I have not tested the RS-232 interfaces. I don't see any warnings or complaints in the logs, and performance appears unchanged. |

Usually in cases like this the Vcc line of the USB port is left disconnected, requiring the user to operate the device from a separate and more powerful supply.
