When mounting on a bulkhead up to 7 mm, a hole only 25 mm in diameter is required to install
the connector. In case of wider bulkheads, a groove of 33 mm diameter at least is required. The groove
(and the hole) can be made with an inexpensive wood drill available world-wide (see Figure 2).

YDNU-02RM and YDNU-02NM USB connectors must be used inside. These models are equipped
with USB Type A Male connectors and designed for direct connection with a PC USB port (not waterproof).
The Device is directly connected to the NMEA 2000 network backbone without a drop cable. 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 it is water resistant and firmly
secured.
The Device is powered from USB, the power supply from the NMEA 2000 network is used for the
isolated part of the network transceiver only. If you have no laptop or PC, you can power the Device with
any USB power adapter (not supplied with a Device) for test purposes.
When the USB cable is plugged in, the Device LED will signal with one flash with a duration of one half
second (see chapter IV for details) and the Device should appear in the list of NMEA 2000 (SeaTalk NG,
SimNet, Furuno CAN) devices or in the common list of external devices on the chart plotter (see Figure 1.
in chapter IX). Usually, access to this list is in the Diagnostics, External Interfaces or External devices menu
of the chart plotter.
