Set up Overview

This is an overview only. Familiarize yourself with the manual and the manuals of any connecting devices before installation. It is always recommended that electronic equipment be installed by an experienced installer.

Before you leave your home:
Consider whether you will need to install a driver. Drivers software is optional and only needed to access your data via USB.

• Windows PC: A driver is required if using Windows and may install automatically, if not, it is included on the FREE CD and Quark-elec.com.
• Mac / Linux: Drivers not required for Mac or Linux.

The software is included on the FREE CD and as a download from www.quark- elec.com. Consider if you have a CD reader/internet access on site if you want to use the above features.

Installation

1. Mounting: Consider your location

2. Dry, sturdy location in reach of your N2K backbone.

3. Ensure you have the correct length of cables needed for VHF and GPS antennas. If drilling holes for your cabling, seal around any holes to prevent damage to your vessel or equipment.

4. Connect your Antennas: VHF and GPS

5. Connect VHF: If you want to use one VHF antenna for both AIS and radio (or other purposes), then you will need an active splitter. An active splitter will protect the A028 and your other VHF equipment (VHF radio). If not, the two signals will significantly damage each device connected as well as reducing the signal. If using two VHF antennas, place them as far away from each other as possible (at least 3 metres).

6. Connect GPS if desired: For best results, the GPS antenna should be located outside where the sky is visible.

7. Connect to NMEA 2000 Backbone The A028 is powered through the NMEA 2000 backbone.

8. Check LED lights are working on the A028 Flashing green lights indicate a valid signal is coming through the A028 from either GPS or AIS.

9. Disconnect power and connect NMEA 0183 output if desired Connect the ‘+’ and ‘-‘ terminals of the NMEA output on the A028 to the ‘+’ and ‘-‘ terminals of the input on the instrument to be connected.
   The A028 outputs NMEA 0183 RS422. If your connecting device uses the older NMEA 0183 RS232 and you are having issues with your NMEA connection, you may find swapping these ‘+’ and ‘-
   ‘terminals works for your device. Alternatively, connect it using a Quark-elec Protocol Bridge (QK-AS03).

10. Connect via USB if required. Windows PCs may require you to install a driver (on CD and www.quark-elec.com). Once the driver is installed simply input the COM port number from your Device Manager into your chart software.

If wishing to connect to a tablet or phone, this device will have to have USB OTG technology. Not all Phones and tablets have ‘USB on the Go’ functionality.

Introduction

The marine Automatic Identification System (AIS) is a location and vessel information reporting system. It allows vessels equipped with AIS to automatically and dynamically share and regularly update their position, speed, course and other information such as vessel identity with similarly equipped vessels. Position is derived from the Global Positioning System (GPS) and communication between vessels is by Very High Frequency (VHF) digital transmissions. There are a number of types of AIS device, like Class A transceivers, Class B transceivers, AIS base stations, Aids to Navigation (AtoN) and AIS receivers. A028 is a compact dual channel, VHF AIS receiver and is able to receive information from both AIS frequencies simultaneously. It includes an integrated GPS module that can track up to 22 satellites on 66 channels. This single data stream is then transmitted synchronously via USB and NMEA 0183 RS422.This single data stream is also converted into NMEA 2000 PGNs and then output through NMEA 2000 to the NMEA 2000 network. The A028 is the perfect entry level AIS Receiver for the latest generation of chart plotters that have an NMEA2000 interface.

NMEA 2000 and NMEA 0183

NMEA 0183 is a serial data interface operating at 4800 bit/second utilizing standard asynchronous communications. NMEA 2000 is a serial data network operating at 250 Kbit/second utilizing the Controller Area Network (CAN). The CAN bus was originally developed for the automotive industry but is now used in numerous industrial applications. The key difference, apart from the obvious one of operating speed, is that NMEA 0183 is an interface while NMEA 2000 is a network. The NMEA 2000 network allows multiple electronic devices to be connected together on a common channel for the purpose of easily sharing information. Because it is a network, and because multiple devices can transmit data, a more comprehensive set of rules is required that dictate the behaviour of the members of the network. The CAN automatically provides some of these rules – mostly for control of access to the network, packet transmission, and for error detection.
Similar to NMEA 0183, NMEA 2000 defines standard data formats and definitions, but in addition provides more extensive network management rules for identifying nodes on the network, sending commands to devices, and for requesting data. Besides the greater amount of control and integration provided, NMEA 2000 replaces with a single cable the wiring of up to 50 NMEA 0183 interconnections and can handle the data content of 50 to100 NMEA 0183 data streams.

Mounting

A028 is designed to be securely mounted to a suitable bulkhead or shelf in an indoor environment and needs to be placed where it is well protected from humidity and water. Although A028 comes with an extruded aluminium enclosure to shield it from external RF interference, it should not be fitted close to generators or compressors (e.g. refrigerators) as they can generate substantial RF noise. It is designed to be installed in a protected indoor environment. Generally, a suitable placement of A028 is together with other types of navigation equipment and the PC or chart plotter that will be used to display the output data. The following Figureure shows an overview of the QK-A028.

Connecting

A028 has the following electrical connections/indicators and outputs:

• AIS antenna connector. Standard BNC female 50 Ohm connector. An active VHF antenna splitter is required if one VHF antenna is shared by A028 and VHF voice radio.
• GPS antenna connector. Standard powered SMA female 50 Ohm connector to connect with an active GPS antenna.
• NMEA 2000 output BUS connectors. A028 can be connected to the standard NMEA 2000 network through NMEA 2000 output connector.
• NMEA 0183 output connectors. A028 can be connected to other AIS compatible equipment, like chatter plotter, via the NMEA 0183 RS422 output. The A028 outputs NMEA 0183-RS422. If your connecting device uses the older NMEA 0183-RS232 and you are having issues with your NMEA connection, you may find swapping these ‘+’ and ‘-‘ terminals works for your device. Alternatively, connect it using a Quark-elec Protocol Bridge (QK-AS03 https://www.quark-elec.com/product/qk-as03-nmea0183-to-garmin-bridge-board/).

USB connector
A micro USB connector outputs the NMEA messages. A028 sends out NMEA 0183 messages via USB. Windows PCs may require you to install a driver (on CD and www.quark-elec.com). Once the driver is installed simply input the COM port number from your Device Manager into your chart software (see chapter Connection via USB port). If wishing to connect to a tablet or phone, this device will have to have USB OTG technology. Not all Phones and tablets have ‘USB on the Go’ functionality. A028 is not supplied with a VHF or GPS antenna as the type of antenna and cable requirements differ from vessel to vessel. A suitable VHF or GPS antenna will need to be connected before the receiver will operate fully.

Power up
A028 runs on 12.0V DC and is powered through the NMEA 2000 network, this allows a much cleaner supply and an improvement in signal reception.

Antennas

AIS communication systems use frequencies in the maritime VHF band, which is considered to be ‘line of sight’ radio. This means that if the A028 antenna cannot ‘see’ the antennas of other vessels, the AIS signals from vessels will not reach A028. In practice, this is not a strict requirement, a few buildings and trees between them will be fine. Large obstacles such as hills and mountains, on the other hand, will significantly degrade the AIS signal
To have the best possible receiving range, the AIS antenna should be placed as high as possible with a relatively clear view of the horizon. Large obstructions might shade the AIS radio communication from certain directions, giving uneven coverage. AIS communication system frequencies are close to the duplex channels used for marine communication, so the antenna should be separated as much as possible (ideally at least 3.0 meters) from the voice communication VHF antenna to avoid unnecessary adjacent channel interference. If you want to use one VHF antenna for both AIS and radio (or other purposes), then you will need an active splitter. An active splitter will protect the A028 and your other VHF equipment (VHF radio). If not, the two signals will significantly damage each device connected as well as reducing the signal. If using two VHF antennas, place them as far away from each other as possible (at least 3 metres).

Connection to Output Devices

A028 provides two NMEA message output types using 3 different connections

Connection via NMEA 2000
The NMEA 2000 outputs converted AIS messages in NMEA 2000 PGNs. Many modern on board electronic system now utilize the NMEA2000 interfacing standard to allow inter-connectivity and interfacing between systems. This is an easy plug ‘n play solution that allows reliable on board data sharing with simple common connectors. NMEA 2000 devices connect on a cabled “backbone” with a “T-connector” used to spur off to each device. A028 comes with an integrated NMEA 2000 cable which can be connected directly to the N2K backbone.

Connection via NMEA 0183
The NMEA0183 connector provides the links to a chart plotter and other instruments. It consists of two differential output wires. NMEA 0183 output operates at a baud rate of 38400bps. The connected chart plotter should be conFigureured at this rate to receive accurate data.

Connection via USB Port
A028 is supplied with a USB connector. This connector provides AIS and GPS data output as standard (multiplexed information from other instruments will also be sent via these connections). This USB connector can be linked directly to a USB port on the PC. It can also be connected to other mobile devices if they have a USB OTG (On the Go) connection using the supplied cable.

Will your device need a driver?
Windows: To enable the USB data connection of A028 to other devices, related hardware drivers may be needed dependent on your system requirements. Windows 7,8,10 the driver can be found on the CD in the packing box . The A028 registers itself to the computer as a virtual serial com port. The drivers usually install automatically to your device if it is running an original Windows 10 version. A new COM port will automatically show up in the device manager after plug in. Mac: For Mac OS X, the A028 will be recognized and shown as a USB modem. The ID can be checked with the following steps:

1. Plug the A028 into a USB port and launch Terminal.app.
2. Type: less /dev/sub
3. The Mac system will return a list of USB devices. A028 will display as – “/dev/tty.usbmodemXYZ” where XYZ is a number. Nothing further needs to be done if it is listed.

Checking the USB connection (Windows

After the driver is installed, run the Device Manager and check the COM number (this is the number associated with the USB port you are using. The port number is the number that Windows assigns as an input device. These can be generated randomly by your computer). Your chart software may require your COM number in order to access the data. The port number for the A028 can be found in Windows ‘Control Panel- System->Device Manager’ under ‘Ports (COM & LPT)’. Find the A028 in the list for the USB variant. To change this number, double click the A028 and select the ‘Port Settings’ tab. Click the ‘Advanced’ button and change the port number to the one required. Checking the USB data flow: If desired, the USB data can always be checked with a terminal monitor application, like Putty or HyperTerminal. To do this, enter the following into the COM port settings: Bits per second: 38400bps, Data bits: 8, Parity: None, and Stop bits: 1.

Status LED’S

LED lights. A028 features three LEDs which indicate power, AIS and GPS status respectively. Three LEDs turn on and then off after initialization. When operating, these LEDs flash as below:

• Power: Top LED flashes at 3 second intervals.
• AIS: Middle LED Flashes for each valid AIS message received.
• GPS: Bottom LED Flashes every second while receiving a valid GPS message

Chart software

There is a wide range of chart software is available such as Imray, PolarView and OpenCPN.

ttps://opencpn.org/ OpenCPN (Open Chart Plotter Navigator) is a free software project to create concise chart plotter and navigation software, for use underway or as a planning tool.

OpenCPN interface comes with a basic map view. You can easily download more detailed maps. There is a wide range of free and licensed charts available in different formats via the OpenCPN website at https://opencpn.org/OpenCPN/info/chartsource.html. A worldwide directory of free nautical charts can also be found on openseachart.org. The collection and the updates are community driven.

Support AIS message

A028 receives all class A/B messages transmitted on two AIS channels. The following messages (above 95% of all AIS messages) will be converted to NMEA 2000 PGNs and send to NMEA 2000 network. However the operator can still monitor and receive the rest in NMEA 0183 format through USB and NMEA 0183 port.
