data will be sent out through USB and NMEA 0183 port simultaneously. The user can use any
USB port monitor software (e.g. OpenCPN) to observe or record the data on PC or OTG (the baud
rate should be set to 115200bps for this function).
3.1. Connecting AS08 via USB for Windows configuration
3.1.1. Will you need a driver to connect via USB?
In order to enable the USB data connection of the AS08, related hardware drivers may be needed
dependent on your system requirements.
For Windows versions 7 and 8, a driver will be needed for configuration but for Windows 10, the driver
usually installs automatically. A new COM port will automatically show up in the device manager once
powered and connected via USB.
The AS08 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.
3.1.2. 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’ under ‘Ports (COM
& LPT)’. Find something similar to ‘USB-SERIAL CH340’ in the list for the USB port. If the port number
needs to be changed for some reason, double click the icon in the list
and select the ‘Port Settings’ tab.
Click the ‘Advanced’ button and change the port number to the one required.
