QUARK-ELEC QK-AS07 NMEA 2000 GPS and Heading Sensor

Introduction

The AS07
The QK-AS07 is a high-accuracy, GPS, Glonass and Galileo GNSS positioning receiver. AS07 features superior sensitivity for consistent signal acquisition, reliable position accuracy, and accurate speed and course-over- ground readings. The AS07 is designed for marine environments and suitable for other outdoor and vehicular use, with an IPX6 waterproof housing. The AS07 can be connected 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 can be used out of the box, to provide instant positional data to your NMEA 2000 bus. Alternatively, the AS07 can be used with the AS07-C Optional Output Switch. The AS07-C provides additional Configuration/Conversion, specifically:

•  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).

•  Backward compatibility with NMEA 0183 devices.
  GPS, Glonass and Galileo GNSS

• The AS07 receives and processes 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 accesses more than one GNSS, the AS07:

•  increases location accuracy and

•  maximizes reliability in case one system is out of range or inaccessible.

Installation and Operation

Dimensions, Mounting and Location

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

Connections

The AS07 sensor has the following connections.

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

NMEA 2000 – Connecting to the NMEA 2000 network
The AS07 sends positional data PGN messages, through the NMEA 2000 bus, to be available to al connected devices. The AS07 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.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 becaus multiple devices can transmit data, a comprehensive set of rules dictates the behavior of the networkdevices. The CAN automatically provides some of these rules for control of access to the network, packet transmission, and for error detection. This product is designed to be used in NMEA 0183 is a serial data interface operating at 4800bps utilizing standard asynchronous communications. The key difference, apart from the obvious one of operating speed, is that NMEA 0183 is an interface while NMEA 2000 is a network. 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, sendingcommands 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 (AS07-C)
The AS07 is designed to be used out of the box, for instant positional data to your NMEA 2000 bus. Alternatively, the AS07 can be used with the AS07-C (optional purchase) for, 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.
•  Backward compatibility with NMEA 0183 devices.

AS07-C Connections

When used with the AS07-C, instead of an NMEA 2000 connection, the AS07 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 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
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 AS07, related hardware drivers may be needed dependent on your system requirements.
Mac:
No driver required. For Mac OS X, the AS07 will be recognized and shown as a USB modem. The ID can be checked with the following steps:

1.  Plug the AS07 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 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 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.

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 ‘ControlPanel>System>Device Manager’ under ‘Ports (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 and select the ‘Port Settings’ tab. Click the ‘Advanced’ button and change the port number to the one required.

The Configuration tool (Windows PC)

NMEA 0183 wiring – RS422 or RS232?
AS07 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 labeling. 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 is needed.
