The new model of YDNG-03 has appeared to replace the old model YDNG-02. In addition to all features of the old model, it is certified by NMEA, supports more message types, has routing between RX and TX lines of NMEA 0183 port and offers a fast heading option for radar.
The Gateway has one NMEA 0183 port with four data lines: two lines to transmit data (TX+ and TX-, multiple "listeners" can be connected) and two lines to receive data (RX+ and RX-, one "talker" can be connected). The port speed can be configured from 300 to 115200 baud.
The routing feature allows forwarding of selected or all NMEA 0183 sentences from RX lines to TX lines. For example, you have a depth transducer with a NMEA 0183 interface, wind sensor with NMEA 2000 interface, and the need to connect both to the NMEA 0183 port of your chart plotter. The Gateway can combine the NMEA 0183 depth sentences from RX lines with wind sentences converted from NMEA 2000 data, and send it to TX lines (see the picture above, left). This saves one NMEA 0183 input on a chart plotter.
In another case, you may decide to install a new NMEA 2000 wind sensor, but you have no free NMEA 0183 ports on your old chart plotter to connect a gateway from NMEA 2000 to NMEA 0183 and put the wind data on it. If you implement the YDNG-03 you don't need a free port; see the connection scheme on the right side of the picture above.
The Gateway supports bi-directional conversion of AIS, autopilot, waypoints and routes and other major data types of NMEA 0183 and NMEA 2000. The new YDNG-03 model also supports conversion of fluid level, battery status, engine and transmission messages of NMEA 2000, which has no corresponding sentences in NMEA 0183 (except the RPM sentence with engine revolutions and pitch, but many other engine data types like oil pressure or coolant temperature have no corresponding sentences) to $MXPGN and $PCDIN sentences with raw NMEA 2000 data. These sentences are supported in some marine software, including iNavx. They are also supported in all our NMEA 0183 products. The $PCDIN sentence can be converted in both directions.
The fast heading option (turned off by default) allows transfer of HDG sentence with 12 Hz frequency (80 milliseconds between messages) for using with radars. Note that this frequency practically consumes 4800 baud channel. Below is a part of a YDNG-03 log:
The $YDHDG and $YDMDA sentences are 77 bytes in total, and at 4800 baud speed they require 77/480=0.16 or 160 milliseconds. And in the log above you can see that the next $YDHDG was sent 161 milliseconds after.
To use the fast heading at 4800 baud, you will need to turn off all other sentences or all long sentences at least.
