II. Installation and Connection to NMEA 2000 or CAN Networks
Never connect both connectors of the Device to the same NMEA 2000 or CAN network.
This can flood the network with infinite forwarding of messages and cause a temporary
inoperability of the network.
The Device requires no maintenance. When deciding where to install the Device, choose a dry mounting
location. Avoid places where the Device can be flooded with water; this can damage it.
Device can be directly plugged into to the network backbone connector. YDNG-07N model can also be
connected via standard "DeviceNet NMEA 2000 Micro" drop cable. If you have a CAN bus with a non-
standard physical layer, connect CAN bus rails and power rails according to Device pinout given in
Appendix C. Before connecting the Device, turn off the bus power supply. Refer to the manufacturer’s
documentation if you have any questions regarding the use of connectors:
• SeaTalk NG Reference Manual (81300-1) for Raymarine networks
• Technical Reference for Garmin NMEA 2000 Products (190-00891-00) for Garmin networks
After connecting the Device, close the lock on the connection to ensure water resistance and reliability.
The microcontroller of the Device is powered by the CAN1 interface. The Device will not work until the
CAN1 interface is powered up. If you want to start up the Device for familiarization purposes or you
implement a custom data processing device which does not need to send data between CAN1 and CAN2
interfaces by design, CAN2 interface can be left unconnected.
The Device has a LED which flashes red or green. When Device CAN1 interface is powered, LED will
produce a series of 2 flashes 5 seconds apart. If this does not happen, see Appendix A.
