4. Check LED lights are working on the A012.Flashing green lights indicate a valid signal is coming through the A012 from GPS satellites.

Need to connect wirelessly?

On your device (phone, laptop etc.): 15 seconds after the A012 has powered up, you can scan for a WiFi network with an SSID similar to ‘QK-A012xxxx’. Connect the device to ‘QK-A012xxxx’ with the default password: ‘88888888’. Chart software: set the protocol as ‘TCP’, IP address as ‘192.168.1.100’ and the port number as ‘2000’ in the chart software.

Need to WiFi settings?
The device is set to connect wirelessly in Ad-hoc mode (with no need for a router or access point). If you want to change to Station mode (connecting through a router) or adjust other setting, see the Configuration software and configuration instructions on the CD provided.

Introduction

A012 is a compact GPS receiver which receives information from GPS satellites. The A012 was originally designed for accessing location data for use in marine technology. The A012 can be used for many different applications including automotive and recreational uses.
The A012 receives and processes GPS signals from satellites, this means that with a power supply (even a power bank) and GPS antenna, the A012 can calculate its location anywhere in the world. The antennas must have 4 out of a possible 33 satellites available in order to triangulate the data and calculate the antenna’s location.
With added WiFi functionality, the GPS data can be accessed wirelessly through peer to peer (Ad-hoc) or station mode WiFi connection.

Mounting

A012 is designed to be securely positioned in an indoor environment and needs to be placed where it is well protected from humidity and water. A012 is not supplied with GPS antenna. An active GPS antenna with a female SMA connector should be mounted and ideally spaced 0.5 metres from other antenna. Although A012 comes with an extruded aluminum 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. So generally a suitable placement of A012 is together with other navigation equipment and the PC or chart plotter that will be used to display the location data.

Connecting

The A012 is typically powered by PC, laptop, tablet or other devices with 5.0V USB micro B connector. If USB data output isn’t required (if accessing GPS data through WiFi), a power bank or other 5.0V supply (greater than 500mA current) power source can be used.
We recommend not using a cigarette lighter as they frequently provide an unstable current, which could damage the A012. Check that the power source is 5.0V volts only. Excess power or power surges/fluctuations can damage the A012.
If you have an unstable power source, we can recommend the A013; this is a dedicated

12.0V/24.0v to 5.0V power converter for marine and automotive purposes that will supply a stable power source. See link below.

QK-A013 12V to 5V Low Interference Converter

The A012 has the following electrical connections/indicators:

• USB connector. A USB micro B connector provides the 5.0V power source for the product and also outputs data.
• GPS connector. Standard SMA male 50 Ohm connector. (required a GPS antenna)
• WiFi connection: WiFi connectivity in both Ad Hoc and Station modes.

Wireless Connections
The A012 allows users to view their data through WiFi on a PC, tablet, smartphone or other WiFi enabled device. Users can access marine network data including vessel course, speed, position, wind speed, direction, water depth, AIS etc. These can be viewed in your chart software (See chapter below, ‘using openCPN-free software)

The IEEE 802.11b/g wireless standard has two basic modes of operation; Ad-hoc mode (peer to peer) and station mode (also called infrastructure mode).

The A012 supports both:-

• In Ad-hoc mode WiFi: mobile devices connect directly (peer to peer) to another device, without a router or access point. For example, your PC, tablet or smartphone can connect directly to the A012 to receiver marine data.
• In Station mode WiFi: wireless devices communicate through an access point (AP) such as a router that serves as a bridge to other networks (such as the Internet or LAN). This allows your router to handle the data and traffic from your device. This data can then be picked up through your router anywhere on your local area network. This is similar to plugging the device directly into the router by wire, but instead using wireless technology. In this way, the mobile devices receive both your marine data and other AP connections for example Internet.

The A012 is set to Ad-hoc mode as a default setting, but can be easily setup to station mode through the configuration tool (GUI).

WiFi Ad-hoc

ON YOUR DEVICE (phone, laptop etc.):
15 seconds after the A012 has powered up, you will be able to scan for a WiFi network with an (SSID) similar to ‘QK-A012xxxx’.
Connect the device to ‘QK-A012xxxx’ with the default password: ‘88888888’.

IN YOUR CHART SOFTWARE:
Set the protocol as ‘TCP’, IP address as ‘192.168.1.100’ and the port number as ‘2000’ in the chart software.

With the above settings, a wireless connection should be established and the user will be able to receive the data through the chart software.
Note: In Ad-hoc mode, the IP address should not be changed. SSID and password can be changed; the password should be between 8 to 12 characters.
You can always check the wireless connection with TCP/IP port monitoring software as shown below:

WiFi Station mode

This allows your router to handle the data and traffic from your device. This data can then be picked up through your router anywhere on your local area network. Similar to plugging the device directly into the router by wire, but instead using wireless technology.
This allows your main mobile device to still receive internet and for you to be able to view the data.
To begin using station mode the Quark-elec instrument should be attached to a computer running windows (for Mac user’s windows boot camp) via USB.

1. Connect A012 to computer via Micro USB B connection.
2.  Run the Configuration tool and check connection to A012 at the bottom of configuration tool.
3. Change working mode to ‘Station mode’
4. Enter your router’s SSID.
5. Enter the password for your network.
6.  Enter the IP address you want to assign to the A012. Start with 192.168. The third group of digits depends on your router’s configuration (Commonly 1 or 0). The fourth group must be a unique number between 0 and 255. This number must not be used by any other equipment connected to your router.
7. Enter your router’s IP address in the Gateway section. This can usually be found under the router. Leave the other settings as they are.
8. Click ‘Config’ in the bottom right hand corner and wait 60 seconds. After 60 seconds Click ‘Disconnect’.
9. Repower your A012. The A012 will now attempt to connect to your router.
10.  In your chart software set the protocol as ‘TCP’ Insert the IP address you assigned the A012 Enter the Port number as ‘2000’ in the chart software.

You should now be connected and see A GPS targets on your chart software.

If not then check your router’s IP address list and check the IP address that your router has given your A012. Occasionally, a router assign a different IP address to a device than the one you chose to assign it during Configuration. If this is the case, copy the IP address from the router into your chart software. If the IP address in your router’s IP address list is the same as the one you input into your chart software then everything will work in station mode. If you are unable to see any data repeat the steps, and check all the data has been input correctly.

If you are not able to view your data in Station mode, the likely cause is either the data has been input incorrectly, or the IP address is different in your chart software to that of your router.

Connecting via USB port
A012 is supplied with a USB connector. This connector provides power supply for GPS data output as standard This USB connector can be linked directly to a USB port on the PC. It can also be connected to other mobile devices via an USB OTG(On the Go) connection using the supplied cable.

Windows: To enable the USB data connection of A012 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 or be downloaded from https://www.quark-elec.com
The A012 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 A012 will be recognized and shown as a USB modem. The ID can be checked with the following steps:

1.  Plug the A012 into a USB port and launch Terminal.app.
2.  Type: less /dev/sub
3. The Mac system will return a list of USB devices. A012 will display as – “/dev/tty.usbmodemXYZ” where XYZ is a number. Nothing further needs to be done if it is listed.

Linux: No driver is required for Linux. When plugged into the computer, A012 will show up as a USB CDC device on /dev/ttyACM0.

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 A012 can be found in Windows ‘Control Panel->System->Device Manager’ under ‘Ports
(COM & LPT)’. Find the A012 in the list for the USB variant. To change this number, double click the A012 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 as shown below using HyperTerminal on Windows as an example

Status LED’S
The A012 features two LEDs which indicate power and GPS status. The two LED’s turn on and then off after initialization. When operating, these LED’s flash as below:

Power LED: left LED flashes at 3 second intervals.
GPS LED : right LED Flashes every second while receiving a valid message

Chart software

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