The Device works with a system CDC ACM driver. After connection of the Device, type the following 

command in the terminal:

dmesg

The output’s tail contains the Device’s properties and port name:

[98.454005] usb 2-2.1: Product: NMEA 2000 USB Gateway

[98.454009] usb 2-2.1: Manufacturer: Yacht Devices Ltd.

[98.454013] usb 2-2.1: SerialNumber: 00090001

[98.461125] cdc_acm 2-2.1:1.0: ttyACM1: USB ACM device

The port name for use in applications is /dev/ttyACM1 (printed in the last line of the output). You can type 

the following command in the terminal to check the port name:

ls /dev/ttyA*

Note that after connection, the modem manager can open a Device for a minute and the Device  

will not be available for use in other applications at this time. In this case, you can instruct the modem 

manager to ignore the Device using the USB identifiers of the product (VID and PID):

echo ATTRS{idVendor}==\"0483\" ATTRS{idProduct}==\"a217\",

ENV{ID_MM_DEVICE_IGNORE}=\"1\" > /etc/udev/rules.d/ydnu.rules

sudo udevadm control –reload
