VI. Device Settings
To configure the Device, a text file with the configuration should be created and named YDNG.TXT
in the root folder of the MicroSD card. A sample of the configuration file is in Appendix E.
The file contents must conform to these rules:
•
parameters and their values must be entered in UPPER CASE;
•
each parameter must be on its own line;
•
commentary lines must start with the # symbol.
Insert the card with a configuration file into the Device and in a few seconds you will see three LED signals
(see Section V) indicating that the configuration file has been processed. A file named YDNGSAVE.TXT
will be created on the memory card with the current configuration of the Device. After the three
LED signals, you can remove the card and check the new YDNGSAVE.TXT file to be sure that
the configuration file has been properly interpreted.
You also can load an empty configuration file (zero length) into the Device to get the YDNGSAVE.TXT file
with the full configuration of the Device and then use it as a template to configure the Device.
1. 0183_SPEED=x
Where x – any speed from 300 to 115200 baud with increments of 300.
Factory configuration: 4800
The default speed of a NMEA 0183 port is 4800 baud, but speeds of 9600 (Navtex) and 38400 (AIS)
are also widely used. Some equipment has no speed selector, but you can switch the port type between
“NMEA”, “Navtex” and “AIS” (or something similar). Even though a port is labeled “AIS” type, usually
that only means that it works at 38400 baud and processes not only AIS, but all other NMEA 0183
messages too.
The general rule is that a slower connection is more robust. However, 4800 baud allows transferring
of about 480 symbols per second. If equipment send a lot of data (for example, depth, wind, speed,
and GPS data) it is possible that the data block will be above 1000 bytes, and that data will be updated
