Before geing started
The wire colours used in this quick start guide are in accordance with
the NMEA 0183 specication (v.4.10, June 2014) and are for illustration
purposes only. Please ensure you check the wiring colours in the
installation instructions for the device you wish to interface to the NDC-5.
Introduction & Features
The ve NMEA 0183 inputs can be routed to any of the two NMEA
0183 outputs, as well as the serial and Ethernet ports providing a highly
customisable network. The bi-directional serial port and Ethernet port also
allow for simple conguration and diagnostics using Actisense software.
Industry leading isolation is provided on all inputs and outputs as standard,
so that connected devices safely avoid hazardous ground loops, the number
one cause of product failure in NMEA 0183 networks. This makes the NDC-5
robust enough to handle any NMEA 0183 installation.

Mounting the NDC-5
The NDC-5 can be mounted using a DIN rail (kit sold separately) or directly on
to a at bulkhead using the screw holes in each corner of the orange base.
Powering the NDC-5
The NDC-5 can operate between 9 and 35 VDC and will typically use
110mA at 12 VDC. The power supply should be connected to the NDC-5 in
accordance with the diagram below.

Connecting to Devices
Strands of wire must not be twisted before inserting in to the connector, this
will ensure a much more secure termination than if the wires are twisted.
A small at headed screwdriver (2-3mm) is needed to loosen the screws on
the pluggable connectors for the wires to be inserted or removed.

LED Colour State Description User action
Power Blue Pulsing Indicates presence of power None required
Status LED
Red Flashing/ solid Buffer Full – Overload condition,
sentences are being dropped.
Connect device to PC browser and review conguration
as a connected device may not receive all sentences
Yellow Flashing/ solid
Warning, buffer is lling. Duplicate deletion
is managing to maintain output capacity
by deleting older copies of sentences
Review conguration to understand the required rates of
sentences which is acceptable to any connected device
Green Flashing/ solid No error No action required
-Off
No data passing through outputs. Either
no input data, or if RX LED is active it
means all data is blocked.
Check if connected Talker is sending data. If it is, review
conguration.

Green Flashing Data available on any one of the NDC-5
inputs No action required
-Off
No data available on this input or
autobaud detection in progress (up to 20
seconds)
Check if connected Talker is sending data. If it is, review
conguration.
Ethernet Green Flashing Data activity on the Ethernet port No action required
-Off No data available Check data Ethernet network
Power and status

Power = blue
Status = red Power = on, Status = on Critical HW Error Both Power & Status LEDs are solid Return to manufacturer if this persists after a power reset
Web browser configuration tool
The Conguration Tool for the NDC-5 is built-in and can be accessed via the
Ethernet connection. An internet connection is not required to access the
Conguration Tool. The factory default log-in for both username and password
is “admin”. A future rmware update will allow individual username and
password log-ins to be remembered and used.
Standard Ethernet networks
If the NDC-5 is connected to an Ethernet network containing both DHCP and
DNS servers, launch any popular web browser and enter ‘http://ndc-xxxxxx’ in
to the address bar (replacing ‘xxxxxx’ with the product’s serial number).
Direct connections or basic Ethernet networks
If the NDC-5 is connected directly to a PC (or the Ethernet network does not
have a DHCP server), the NDC-5 will communicate using auto-IP by default.
The auto-IP process can take up to 60 seconds to complete.
