Introduction

The AS07-N2K

The AS07-N2K contains two integrated sensors within the single unit

• a multiple GNSS positioning sensor and
• a three-axis magnetic compass.

The AS07-0183 can be used out of the box and features superior sensitivity for consistent signal acquisition, reliable position accuracy, and accurate speed and course-over-ground readings. The AS07N2K is designed for marine environments and suitable for other outdoor and vehicular use, with an IPX6 waterproof housing. Additionally, from may 2021 onwards it also features heading information.
The AS07-N2K can be connect directly to the NMEA 2000 backbone. It is powered by the NMEA 2000 backbone with no need for additional configuration.

The AS07-C (optional purchase)

The AS07-N2K can be used out of the box, to provide instant positional and heading data to your NMEA 2000 bus.
Alternatively, the AS07-N2K can be used with the AS07-C Optional Output Switch. The AS07-C provides additional Configuration/Conversion, specifically:

1. Optional additional configuration using Windows PC,
   • Filtering of desired NMEA 2000 PGN messages, to eliminate unwanted data.
   • Adjusting the frequency of NMEA 2000 data (1/2/5/10 per second).
   • Calibratable to compensate for magnetic deviation(very rarely required)

2. Backward compatibility with NMEA 0183 devices.

GPS, Glonass and Galileo GNSS

The AS07-N2K receives and process messages from GPS, Galileo and Glonass positioning satellites. GPS, Galileo and Glonass are all space-satellite based navigation systems, also known as Global Navigation Satellite Systems (GNSS).

• GPS (Global Positioning System), was created by the US government and operated by the US Space Force.
• GLONASS provides a comparable alternative to GPS. It was created by Russia.
• GALILEO was created by the EU through the European GNSS Agency.

Global Navigation Satellite Systems work by triangulating data from several satellites. At least three satellites from a system must be accessible/in range to triangulate a location fix.
By accessing more than one GNSS, the AS07-N2K:

• increases location accuracy
• maximizes reliability in the event one system/satellite is out of range or inaccessible.

Compass Heading

The AS07-N2K is actually two sensors in a single unit; a multiple GNSS positioning sensor and a threeaxis magnetic compass. Simply connect it to the NMEA 2000 backbone and it will immediately start calculating the heading of the boat and outputting this data. You can filter out this message type if not required (using the Windows Configuration tool with AS07-C).

Installation

Dimensions, Mounting, and Location

Figure 1 AS07-N2K Dimensions

AS07-N2K is designed to be securely positioned in an outdoor environment. The AS07-N2K should be mounted to a strong and sturdy location. The AS07-N2K has a standard G 3/4 screw thread and can be installed using the corresponding antenna base (included) or a G ¾ Base of your choice.

Mount the AS07-N2K in a:

• Sturdy outdoor location, with `line of sight’ to the sky
• As close to the vehicle/boat’s center of gravity as possible. Avoid mounting too high up, to ensure a more accurate compass reading
• Minimum 0.3 meter from other compasses (standard and steering)
• Minimum 2 meters from a VHF antenna
• Ensure the mounting location will not disrupt moving equipment (eg. Radar)
• Do NOT install near ferrous metals or anything that can create a magnetic field such as: magnetized materials,
• electric motors, electronic equipment, engines, generators, power/ignition cables, and batteries.
• Do not install within a steel/ magnetic container , including not within the hull of a steel boat/vehicle
• With the correct orientation. AS07-N2K has two raised lines on the tube, the center point of these should be pointed straight forward, towards the front of the boat, as illustrated.
• If this is not possible, you can configure this adjustment to +90 to ­90 degrees using the Windows configuration tool. (See the Configuration chapter for more details)

Connections

The AS07-N2K sensor has the following connections.

• NMEA 2000 port. The AS07-N2K is powered by the NMEA 2000 bus and sends positional and heading data (PGN messages) through the NMEA 2000 bus, to be available to all connected devices.
• G 3/4 thread for connection to chosen base.

Figure 2: Typical system connection

NMEA 2000 – Connecting to the NMEA 2000 network

The AS07-N2K sends positional and heading PGN messages, through the NMEA 2000 bus, to be available to all connected devices.
The AS07-N2K is pre-fitted with a five-core screened cable for the NMEA 2000 connection, fitted with a male micro-fit connector. Simply connect the cable to the network backbone using a T-piece connector. It will work immediately once connected to a powered NMEA 2000 bus.

Figure 3: 5 Pin NMEA 2000 male micro-fit connection

NMEA 2000 is a serial data network operating at 250 Kbit/second utilizing the Controller Area Network (CAN). 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 comprehensive set of rules dictates the behavior of the network devices. The CAN automatically provides some of these rules 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 to 100 NMEA 0183 data streams.

AS07-C: Using the Optional Output Switch

The AS07-N2K is designed to be used out of the box, for instant positional data to your NMEA 2000 bus.

Alternatively, the AS07-N2K can be used with the AS07-C (optional purchase) for,

1. Additional configuration using Windows PC,
   • Filtering of NMEA 2000 PGN messages, to eliminate unwanted data.
   • Adjusting the frequency of NMEA 2000 data. The default setting is 1 Hz (data transferred once per second) The frequency can be set to 1/2/5/10 per second. 1Hz is the default setting and is generally recommended. Please note: 10 Hz may cause data overflow on the NMEA 2000 system.
   • Calibratable to compensate for magnetic deviation (very rarely required)

2. Backward compatibility with NMEA 0183 devices.

AS07-C Connections

Figure 5: AS07-C Connections

When used with the AS07-C, instead of a NMEA 2000 connection, the AS07-N2K with the AS07-C can have the following connections:

• Power: 12V and GND terminals need to be connected.
• USB: A type B micro-USB connection allows for connection to a PC. This connection is used to adjust optional additional settings (see Configuration section).
• NMEA 0183 output: AS07-N2K sends out the GNSS messages via the NMEA 0183-RS422 output at a baud rate of 4800bps as default (Baud rates can be adjusted, see configuration section).

Connecting AS07-C via USB for Windows Configuration

The AS07-C is supplied with a USB connector. The USB cable can be linked directly to a USB port on a PC.

Will you need a driver to connect via USB?

To enable the USB data connection of the AS07-N2K, related hardware drivers may be needed dependent on your system requirements.

Mac:
No driver required. For Mac OS X, the AS07-N2K will be recognized and shown as a USB modem. The ID can be checked with the following steps:

1. Plug the AS07-N2K into a USB port and launch Terminal.app
2. Type: Is /dev/sub
3. The Mac system will return a list of USB devices. AS07-N2K will display as – “/dev/tty.usbmodemXYZ” where XYZ is a number. Nothing further needs to be done if it is listed.

Windows 7,8,10:
The drivers usually install automatically if your device is running an original Windows 10 version. A new COM port will automatically show up in the device manager once powered and connected via USB.
The AS07-N2K registers itself to the computer as a virtual serial com port. If the driver does not install automatically, it can be found on the included CD and downloaded from www.quark-elec.com.

Checking the USB COM Port (Windows)

After the driver is installed (if needed), run the Device Manager and check the COM (port) number. The port number is the number assigned to an input device. These can be generated randomly by your computer). The Configuration software will require a COM port number in order to access the data.
The port number can be found in Windows Control Panel>System>Device Manager’ underPorts (COM & LPT)’. Find something similar to STMicroelectronics Virtual Com Port’ in the list for the USB port. If the port number need to be changed for some reason, double click the AS07-N2K and select the Port Settings’ tab. Click theAdvanced’ button and change the port number to the one required.

NMEA 0183 wiring – RS422 or RS232?

AS07-N2K uses the NMEA 0183-RS422 protocol (differential signal), however some chart plotters or devices may use the older NMEA 0183-RS232 protocol (single- ended signal). Check which protocol your connecting NMEA devices (e.g. Chart plotter) uses. If you are unsure whether your connecting NMEA 0183 device uses NMEA 0183 RS422 or RS232, the input/output connections on the device will give you some indication. Unfortunately, manufacturers who use the older RS232 protocol are not consistent in their product labelling. The following table may help you identify which protocol your product uses, however always check the manual to be certain. If your connecting device uses the older RS232 protocol, use a QK-AS03 Protocol Bridge. The QK-AS03 connects and converts RS422 to the older RS232 and visa-versa, through a simple connection, no configuration needed.

TX+ and TX- / RX+ and RX-
• Swap two wires if not work.| TX+ and TX- (GND) / RX+ and RX- (GND)
TXa+ and TXa- (GND) / RXa+ and RXa- (GND)
