Installation Warnings

All warnings and notices must be followed to ensure the correct operation of the NGT-1. 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 NGT-1 is designed to reliably transfer NMEA 2000 PGNs between the PC and the NMEA 2000 bus; the accuracy of data contained in each PGN is the responsibility of the generating device or software application. Furthermore for each installation requirement the NGT-1 must be congured correctly by the software application. Therefore, the NGT-1 should only be used as an aid to vessel monitoring, control or navigation and should not be used as a replacement for traditional aids and techniques.

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

All wiring should be in accordance with the regional code of practice for installations and meet the NMEA 0400

specication.

Warning 4: Firmware Updates

It is highly recommended that the Firmware is kept up to date in the NGT-1. The latest rmware version number and

details of supporting software such as NMEA Reader can be found on the NGT-1 downloads web page. You can check

the rmware version currently installed in your NGT-1 by locating the manufacturers software ID on the network list

found in most NMEA 2000 MFDs or NMEA Reader.

Warning 5: Mounting Requirements

Select a at location to mount the NGT-1. Mounting on a contoured surface may cause damage to the case. Do not mount the NGT-1 while the device is powered. Do not mount the NGT-1 while the NMEA 2000 cable is connected. Do not mount the NGT-1 while the PC cable is connected.

Warning 6: Mounting Locations

Do not mount the NGT-1 in the same plane as transmitting or receiving antennas. Do not mount the NGT-1 close to an electronic compass.

Page 8

Mounting the NGT-1

• Use the NGT-1 as a template to locate and mark the drill holes for mounting. Do not attempt to drill the holes while the NGT-1 is in position. A mounting guide is provided and can be used to mark the mounting holes if preferred.

• Refer to “Warning 5: Mounting Requirements” on page 7.

• Secure directly to a bulkhead using the two M3.5 stainless steel pan-head screws provided. If these screws are lost, suitable alternatives may be used instead. Note: Using larger screws can damage the housing and invalidate the guarantee.

• Secure directly to a bulkhead using the mounting screws provided with the unit.

Powering the NGT-1

The NGT-1 does not need external power. Power is taken from the NMEA 2000 network (for ISO variant) or from the USB port (USB variant).

Connecting to a USB Port

For USB variants of the NGT-1, simply plug the USB cable on the NGT-1 in to a PC USB port and the USB driver installation will begin. For ISO variants of the NGT-1, a USB to serial converter cable can be used to connect to a PC USB port. For wiring the converter cable refer to “Connecting the ISO cable” on page 10.

Note: Refer to “Status LEDs” on page 13 for LED behaviour.

USB Driver Installation

Windows 7, 8 and 10 will automatically install the drivers from Windows Update if there is an active Internet connection the rst time the NGT-1 is plugged in.

If the PC is not connected to the Internet or if the USB

driver does not install automatically on the rst installation

of the NGT-1, the ‘Update Driver Software’ option in Device Manager will need to be used to install the USB drivers manually.

Windows versions that use the ‘Found New Hardware Wizard’ should be directed to automatically search for the

best driver. Include ‘Search Windows Update’ or ensure the Actisense CD is inserted.

For other operating systems and step-by-step guides refer to the ‘USB Install Manual’.

Windows Port Number Conguration

The port number for the NGT-1 can be found in Windows

‘Control Panel->System->Device Manager’ under ‘Ports

(COM & LPT)’. Find the NGT-1 in the list for the USB variant. When using a USB to serial converter cable you will see the name of the converter cable with no reference to the NGT-1. If you have connected to an RS232 port on

the PC this will be listed as a ‘Communications Port’, again

with no reference to the NGT-1.

To change this number, double click the NGT-1 and select

the ‘Port Settings’ tab. Click the ‘Advanced’ button and

change the port number to the one required.

Page 9

NMEA 2000 to PC Interface - NGT-1

Connecting to an NMEA 2000 Network

The NGT-1 has a male Micro connector as specied by the NMEA 2000 standard. This allows the NGT-1 to be connected directly to an NMEA 2000 bus without complication. If you are using an alternative proprietary CAN bus network, a suitable adapter cable will be required. It is recommended that the manual for any proprietary CAN bus network devices be consulted to determine the suitability of connecting an NMEA 2000 device such as the NGT-1. The NMEA 2000 drop cable on the NGT-1 is 1.5 meters long, which can be extended as required up to a maximum of 6 meters (from the NMEA 2000 backbone), see “Table 1 - NMEA 2000 Cable Length Rules”. Any drop cable extension should be securely connected to ensure reliable operation. Please refer to, “Status LEDs” on page 13

NMEA 2000 Networks

NMEA 2000 devices will only communicate with each other when connected to a powered and correctly terminated NMEA 2000 network. It is not enough to simply connect two NMEA 2000 devices directly together.

All networks need to be powered and terminated correctly to allow data to be transmitted reliably on the network. T-Pieces are needed to connect each device to the network. Additional cable lengths can be used between any of the connectors to extend the length of the network. Ensure the NMEA 2000 rules for cable length are adhered to, see “Table 1 - NMEA 2000 Cable Length Rules”.

NMEA 2000 Minimum Network Requirements

All NMEA 2000 networks require a 12V DC supply.

In addition, a correctly functioning network will require the following components :

• 1 x Power-T

• 2 x Terminating Resistors

• 2 x T-Pieces (one per connected device)

• 2 x NMEA 2000 Devices (such as the NGT-1)

All the required network parts can be supplied by the Actisense A2K range.

Refer to “Figure 2 - NMEA 2000 Minimum Network

Requirements Diagram” for an example network. Note

that the diagram should not be used as an installation guide. NMEA 2000 networks should only be installed

following the NMEA 0400 specication and all wiring

should be in accordance with the regional code of practice for installations.

Connecting the ISO cable

On the ISO variants of the NGT-1, a pre-tted four-core screened cable for connecting to a variety of devices. Actisense

ISO-Drive output circuitry and OPTO input circuitry allows many different types of device to be connected without the

need for conguration. Voltage levels are managed automatically as well as accepting both differential and ground referenced connections safely. This allows connection to a standard RS232 PC port and the exibility to connect to an

RS422 system if required for an embedded application. “Table 2 - ISO Cable Connections” shows the cable assignments used.

Table 2 - ISO Cable Connections

Red Opto In A / + IN A / + OUT positive

Blue ISO Out B / - OUT B / - RS232 ground or RS422 IN negative

White ISO Out A / + OUT A / + IN positive

Bare/Silver Ground ISO GND Not Connected

Connecting to an RS232 (PC) port

When connecting to a standard 9-pin RS232 serial PC port, the cable and a connector must meet the following

specication:

4. Connect the IN -/B and OUT -/B together and connect to the PC’s serial port ground (standard 9 pin D-type, pin 5).

1. A minimum of 3-cores are required in a shielded cable.

Higher quality cable will naturally yield higher performance/ higher Signal-to-Noise Ratio (SNR). Most typical cables have two twisted pairs inside. In this case, use one pair for the TX line and one for the RX line. Use the spare wire in each pair as ground, and connect the cable shield to ground only at the computer end.

2. A DB9 (9 pin D-type) type female (socket) connector for

the PC end of the cable.

3. The OUT +/A of the NGT-1 should be connected to the

RX of the computer (standard 9 pin D-type, pin 2) and the NGT-1 IN +/A should be connected to the TX of the computer (standard 9 pin D-type, pin 3).

Connecting a Custom Cable

The ISO/PC cable is connected inside the NGT-1 case to screw terminals. It is possible to replace the supplied cable

with a custom cable for different applications. A spare cable gland is supplied for strain relief and splash proong. The NMEA 2000 cable is also connected using screw terminals. It is recommended that certied NMEA 2000 drop

cables are used to extend the existing cable rather than replacing it. The supplied grommet is not suitable for correctly

specied NMEA 2000 micro cable.

Opening the NGT-1 Case

To open a NGT-1 case, remove the two screws in the base of the unit, then carefully lift off the top of the case. The cable glands must be slid out from the top of the case in order to access the internal connections. Pulling the lid off too roughly without sliding the glands out may damage to the cable connections. The NGT-1 circuitry will be left attached to the base of the unit and the two supplied cables attached to their connectors.

Custom ISO/PC Cable

The cable should have two shielded twisted pairs: one pair for the input and one pair for the output. The maximum

length of the cable is dependent on the input/output specications of the connected device and the cable quality. Using an unsuitable cable may result in data loss. A spare cable grommet is supplied for strain relief and splash proong a

replacement ISO/PC cable.

Note: When opening an NGT-1 case, be aware that the circuitry inside is not 100% protected against static electricity. Please ensure that you use precautions against static damage by only touching the connector block and by holding the unit by its plastic base.

Note: Any damage caused to the unit while the case is open is not covered by the guarantee.

Custom NMEA 2000 Cable

Replacement NMEA 2000 cable is required to conform in

full to the NMEA 2000 specication and be no longer than

6 metres (maximum drop length).

Refer to “Figure 4 - NMEA 2000 PCB Connections” and

“Table 3 - NMEA 2000 Connection Table”.

Conguring the NGT-1

Conguration Requirements

It is the responsibility of the software application to congure the NGT-1 being used in order to meet its NMEA 2000 requirements. This means that the NGT-1’s conguration will be dependant on the software application’s last used settings. It is possible to manually congure the NGT-1 using Actisense NMEA Reader, as long as it is understood that any such modications could be lost when using the NGT-1 with another software application.

Connecting the NGT-1 to NMEA Reader

Connect the NGT-1 to the PC (by USB cable or RS232 cable depending on variant) and run the NMEA Reader program. Select the port number for the NGT-1 and select the Baud rate. The default Baud rate for the NGT-1 is

115200. NMEA Reader will attempt to communicate with

the NGT-1. Once successful the ‘Hardware Cong’ tab will become available and the green LED indicator next to the

Baud selection will ash.

Note: The COM port must be opened at the baud rate the

NGT-1 is congured to use as there is no auto baud

feature in NMEA Reader. This will typically be 115200 or 230400 baud.

The ‘Hardware Cong’ tab shows the ‘Tx PGN Enable List’, ‘Rx PGN Enable List’, ‘Serial Baud Rate’ and ‘ARL

P-Codes’ options”.

Selecting PGNs for transfer

The NGT-1 has two modes of operation: ‘Transfer: Normal’ and ‘Transfer: Receive All’. In the NGT-1 default ‘Transfer:

Normal’ mode, the PGNs that are received from the NMEA 2000 bus and transferred to the PC software application

are specied in the ‘Rx PGN Enable List’. Disabling a PGN

in the Rx list will stop its transfer to the PC.

Changing the Baud rate

The top ‘Serial Baud Rate’ drop down menu is used to

change the NGT-1 ISO/PC connection baud rate. The bottom drop down menu is disabled as it is currently not required. Select the new NGT-1 baud rate and click the

‘Apply’ button. The new conguration will be sent to the

NGT-1, forcing a reboot so the new baud rate can be enabled. NMEA Reader will re-open its COM port to the new baud rate to continue communication with the NGT-1.

Refer to the log tab to conrm the reboot and reconnect

process has completed before attempting to edit any

further conguration options.

Note: Do not make any other conguration changes when

setting the Baud rate. Some changes may be lost when setting the new Baud rate.

Note: Only USB variants of the NGT-1 are capable of operating at baud rates above 115200. Do not change the baud rate of ISO variants above 115200, as doing so will prevent the NGT-1 from communicating and may require

the device be ‘returned to base’ for reconguration.

Note: Changing the baud rate to less than 115200 Baud may result in some NMEA 2000 PGN messages being lost due to overloading.

However, by default many software applications (including

NMEA Reader) will put the NGT-1 in to ‘Transfer: Receive

All’ so that all NMEA 2000 PGNs can be transferred to the

PC software application. In this mode, the ‘Rx PGN Enable List’ is not used and any user modications to it will not

result in any change of the NGT-1’s behaviour.

The PGN Enable Lists can be refreshed with the NGT-1’s

current values using the ‘Update from hardware” button and reset back to the factory defaults using the ‘Apply defaults to hardware’ (there is no need to press the ‘Apply’

button to complete this operation).

Special ARL P-codes

The ‘ARL (Active Research Ltd.) P-codes’ option enables/

disables transmission of special proprietary messages from the NGT-1 to the PC. There should not be any reason to disable this in an NGT-1, however if required to select

the new behaviour and click the ‘Apply’ button.

NMEA 2000 to PC Interface - NGT-1

Troubleshooting Guide

This guide will concentrate on all relevant troubleshooting issues, that may arise on your NGT-1. Therefore, the cables between the NGT-1 hardware and any other devices should be checked as a matter of course, before continuing with this guide.

Status LEDs

The NGT-1 hardware has two bright LEDs that can be seen through the case to indicate when data is received from either the serial device or NMEA 2000 network connection. It is an important point to note that these two LEDs can only

show when their respective data is RECEIVED; it is not possible to show both transmit and receive simultaneously on a

single colour LED.

These LEDs can be used to debug potential problems using the ‘Behaviour’ and ‘Solution’ details in Table 4 using

NMEA Reader as a diagnostics tool.

Check that the NGT-1 is connected to the NMEA 2000 network and that the NMEA 2000 network is operational refer to “Connecting to an NMEA 2000 Network” on

page 9.

Conrm that at least one periodic PGN message is being sent on the NMEA 2000

network and there are at least two NMEA 2000 devices on the network. If another NGT-1 is available, NMEA Reader can be used to prove the status of the NMEA 2000 network.

Check that the NGT-1 is connected correctly to the PC (via USB or RS232 port) and the software application has opened the COM port connected to the NGT-1 at the matching baud rate. Refer to the relevant connection option from those described on page 8 onwards.

Indicates that the NGT-1 is powered but no data is received from either connection. If valid data should be present and transferred by the NGT-1 on one or both inputs, refer to the two rows above.

Indicates that the NGT-1 has lost its Firmware, please connect the unit to the latest NGT-1 Actipatch and re-install the Firmware. The latest Firmware can be found on the NGT-1 downloads web page.

NMEA 2000 to PC Interface - NGT-1

Minimum NMEA 2000 PGN List

The NGT-1 is capable of transferring any PGN in the NMEA 2000 specication to or from the NMEA 2000 bus depending on the conguration of the NGT-1. Optionally, the NGT-1 can be put in “Transfer: Receive All” mode, which allows the

NGT-1 to transfer any and all PGN messages from the NMEA 2000 bus without limitation. It is impractical to publish the entire NMEA 2000 PGN list, “Table 5 - Minimum NMEA 2000 PGN List” shows the PGN messages that cannot be

disabled by software conguring.
