Installation Warnings

All warnings and notices must be followed to ensure the correct operation of the NDC-5. Incorrect installation may invalidate the guarantee. It is highly recommended that all of the installation instructions are read before commencing the installation. There are important warnings and notes throughout the manual that should be considered before the installation is attempted.

Warning 1: Accuracy

The Actisense NDC-5 is designed to accurately transfer data from input to output. When the NDC-5 is in a Basic Mode no data integrity checking is performed, therefore any incomplete, inaccurate or corrupt data received on a NDC-5 input will be duplicated to the NDC-5 outputs. In contrast, NDC-5 Smart Modes do use the sentence checksum (if available) to remove incomplete and corrupted data, however, the accuracy of the data fields in a valid sentence still remains the responsibility of the NMEA Talker that generated the data.

Warning 2: Installation and Operation
This product must be installed and operated in accordance with the instructions provided. Failure to do so could result in personal injury, damage to your boat and/or poor product performance.

Warning 3: Installation Code of Practice
When wiring the power supply to the NDC-5 ensure the isolation switch is off. Wiring the NDC-5 while the connection is live may damage the NDC-5 and is in breach of the guarantee. Any connection to a battery or power supply must meet the mandatory essential safety requirements that may be imposed by local regulatory agencies. All wiring should be in accordance with the  requirements of the NMEA 0400 installation specification.

Warning 4: Mounting Requirements
Select a flat location to mount the NDC-5. Mounting on a contoured surface may cause damage to the case. Do not mount the NDC-5 while the device is powered, or the cable harness is connected. Note that the connectors are pluggable for easy disconnection when mounting or removing the NDC-5.

Software Updates
The NDC-5 units have built-in firmware which is held in flash memory, allowing quick and easy upgrades using the latest Actisense Toolkit. It is highly recommended that the firmware is kept up to date in the NDC-5. The firmware version installed in the NDC-5 can be viewed on the web based Configuration Tool ‘Home’ page, in the ‘Main Application’ section. Details of the latest NDC-5 firmware version released can be viewed on the Actisense website.

NDC-5 Intro & Features

The NDC-5 is more than just an NMEA 0183 Combiner/Multiplexer; it provides an installer with a highly flexible platform that can be used to solve many NMEA 0183 interconnectivity headaches.
The five 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 configuration and diagnostics using Actisense software. The configuration tool is accessible via any popular web browser (using the Ethernet port) so there are no
PC operating system compatibility issues to contend with. Using the web based configuration tool will allow the user to finely tune the exact data available on each output. The default setup is for all data to go to all outputs.

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. Pluggable connectors allow new devices to be easily installed without the need to remove the NDC-5 from its mounted location. A professional DIN rail mounting mechanism keeps the NDC-5 secure in high vibration environments. Helpful LEDs indicate power, data in, and status conditions to aid diagnostics.

• Ethernet port – for configuration, diagnostics and sharing NMEA 0183 data (future update)
• 5 OPTO-Isolated NMEA 0183 inputs
• 2 ISO-Drive NMEA 0183 outputs
• Advanced Data Filtering/Routing
• Configurable Input and output baud rates
• Autoswitch mode* available to offer system redundancy
• Serial port – for configuration, diagnostics or as an additional NMEA 0183 input/output.
• Free firmware updates make the device future-proof
• Power LED to indicate operational state
• Rx LED to indicate data on inputs
• Status LED (bi-colour) to indicate output Data Overload or a range of other states
• DIN rail or Panel mountable
• Pluggable screw terminal connectors for quick and easy installation.

*Available with future firmware update.

Before getting started

The wire colours used in this manual are in accordance with the NMEA 0183 specification (v.4.10, June 2014) and are for illustration purposes only. Please ensure you check the wiring colours in the installation instructions for the devices you wish to interface to the NDC-5.

Terminals
NDC-5 connectors are pluggable, meaning they can be easily removed for quick and simple wire installation without the need to unmount the NDC-5 from its installed location.

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.

NMEA 0183 Talker and Listener Designations
The NMEA have updated the NMEA 0183 specification to ensure a consistent naming convention is used for labelling ports. The designation follows the same rules as used for Rx and Tx labelling but uses Talker and Listener instead. The input / receiving (Rx) port will be labelled as a ‘Listener’ port. The output / transmitting (Tx) port will be labelled as a ‘Talker’ port. When a port is labelled ‘Listener’ it is an input and when it is labelled ‘Talker’ it is an output.

Connecting to NMEA Devices

The ‘A/+’ and ‘B/-’ of the NMEA 0183 device should be matched to the ‘A’ and ‘B’ on the NDC-5. If the NMEA 0183 device has a ground (GND) wire (and no ‘B/-’ wire), simply connect this to ‘B’ on the NDC-5.

OPTO Inputs
Connect the NMEA 0183 Talker to the NDC-5 Listener terminals as shown in the diagram.

ISO-Drive Outputs
Connect the NMEA 0183 Listener to the NDC-5 Talker terminals as shown in the diagram.

Serial
The connections for a standard RS232 cable are:

Ethernet

Either a standard Ethernet patch or crossover cable with an RJ45 plug can be used for a direct connection to a PC/laptop, or the NDC-5 can be connected to an Ethernet network switch. Insert the RJ45 plug in to the NDC-5 ‘Ethernet’ terminal until a click is heard. To remove the RJ45 plug, push down on the locking clip and pull the cable away from the ‘Ethernet’ terminal.

Mounting the NDC-5

DIN Rail Mounting
Install the DIN rail in the desired location. Fully retract the black securing latch in to the down position. Attach the NDC-5 to the DIN rail as shown in the diagrams below. Ensure the NDC-5 sits flush against the DIN rail, then push the securing latch back in to position to hold the NDC-5 in place.

Bulkhead Mounting
Actisense recommends the NDC-5 is installed using the DIN rail supplied for the most secure installation. However, the NDC-5 can be secured to a bulkhead using the two screw catches on the reverse of the NDC- 5 shown in the diagram below. Two screws must be used 89.4mm apart and horizontally aligned.

Web Browser Configuration Tool
The Configuration Tool for the NDC-5 is built-in and can be accessed via the Ethernet connection. As the Configuration Tool is web based it is compatible with all popular web browsers and Operating Systems. An internet connection is not required to access the Configuration Tool. The default page displayed is the NDC-5 Configuration Tool ‘Home’ page. We strongly suggest bookmarking the ‘Home’ page in your web browser to allow quick and easy future access. To access any of the NDC-5 setup pages, the user is required to log-in. This prevents unauthorised user access from modifying the NDC-5 configuration. The factory default log-in is “admin” for username and “admin” for password. All modifications to the NDC-5 settings, including any user defined ‘User Modes’ are automatically saved inside the NDC-5.

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’ into the address bar (replacing ‘xxxxxx’ with the actual product’s serial number). It is important to include the ‘http://’ section of this address. If it is missing, the browser will conduct a web search.

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. The PC’s “Local Area Connection” must also be setup to use auto-IP in order to communicate on this network most PCs are set to do this by default. If needed, instructions for how to do this using Windows 7 are detailed below (other Windows Operating Systems will be similar). Administrator privileges are required to carry out these instructions in full:

1. Launch the ‘Start’ menu and type ‘Network and Sharing Center’ in the search bar. Select ‘Network and Sharing Center’.
2. In the ‘Network and Sharing Center’ window, select ‘Change adapter settings’.
3. Right click on ‘Local Area Connection’ and select ‘Properties’.
4. Select ‘Internet Protocol Version 4 (TCP/ IPv4)’ but DO NOT untick the box. Then Select ‘Properties’.
5. Under the ‘General’ tab heading, ensure ‘Obtain an IP address automatically’ and ‘Obtain DNS server address automatically’ are selected.
6. Under the ‘Alternate Configuration’ tab heading, ensure ‘Automatic private IP address’ is selected.
7. Accept these changes by selecting ‘OK’.
8. Close the ‘Local Area Connection Properties’ window.

Now that the PC and NDC-5 are using the same IP address range, launch any popular web browser and enter ‘http://ndc-xxxxxx’ in to the address bar (replacing ‘xxxxxx’ with the product’s serial number).

Troubleshooting Guide

First level NDC-5 diagnostics / fault finding can be performed by observing the LED behavior. The normal behavior of the NDC-5 LEDs is described in the table below. If the LEDs are not behaving as expected, this will indicate a fault in either the device connected to the NDC-5, the wiring/connections, or the NDC-5 itself.
Some common check to perform on all terminals of the NDC-5 if the correct LED behaviour is not displayed:

• Connectors are fully inserted
• All pins of the connector are in the correct location (not half in the neighboring connection)
• Wires are terminated firmly and correctly (check polarity)
