====== Node low level configuration ======

The configuration tool for the Node only supports a sub set of all settings in the Node, to access the full configuration connect the Node to a computer with a USB cable. The node will be recognised as a serial port and you need a terminal program to configure it. The procedure is OS specific and some suggestions can be found below

===== Linux =====
The name of the serial port can be found with //dmesg//
<code bash>
$ dmesg
 [ .... ]
[22942.980255] usb 3-2: new full-speed USB device number 13 using xhci_hcd
[22943.109845] usb 3-2: New USB device found, idVendor=0483, idProduct=5740
[22943.109852] usb 3-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[22943.109855] usb 3-2: Product: Loco Positioning Node
[22943.109858] usb 3-2: Manufacturer: Bitcraze AB
[22943.109861] usb 3-2: SerialNumber: 1C0030000F51485336373420

The serial port can be opened with your favorite serial console, picocom: 
<code bash>
$ picocom /dev/ttyACM3
</code>


===== OSX =====
Find the serial port with //ls//
<code bash>
$ ls -a /dev/tty.usb*
/dev/tty.usbmodem1415501
</code>

To open the serial port
<code bash>
$ screen /dev/tty.usbmodem1415501
</code>

===== The menu and configuration =====

When you connect to the Node you will be presented with the current configuration

<code>
