Where:
• echo is a built-in command of an operating system;
• YDNU MODE 0183
is a special command sent to the Device (turn on 0183 mode);
• > (greater-than symbol) is an operator that redirects command output.
We used the same port names (specified after the output redirection sign >) above, as were used
in the examples of chapter III. The command will be confirmed by a one second green signal of the LED
and the value set will be saved to the EEPROM.
The special command YDNU SILENT ON does not actually change the operation mode, but it prohibits
sending of all outgoing messages from PC applications to the NMEA 2000 network, making the Device
“read-only”. We will call this the "silent mode" for simplicity.
echo YDNU SILENT ON > COM3
echo YDNU SILENT ON > /dev/cu.usbmodem00090001
stty -F /dev/ttyACM1 hupcl
echo YDNU SILENT ON > /dev/ttyACM1
This setting is recommended if you are not planning to control the marine systems from PC applications.
It protects the NMEA 2000 network from the threat of flooding caused by an incorrectly configured
PC application. When the “silent mode” is on, the LED signal when the Device powers on is red, otherwise
green (see chapter IV).
The command YDNU SILENT OFF returns the Device to the normal bi-directional mode. Both
(on and off) commands are confirmed by a one second green signal of the LED and the setting will be saved
to the EEPROM.
