  • Serial USB Port

    The [WIKI]GPS receiver[/WIKI] often requires a a driver to be installed before the computer operating system will recognize it, enabling the navigation software to communicate with the receiver. The navigation software must then be configured to specify the type of receiver and protocol to use before it will function properly.

    Some [WIKI]GPS receivers[/WIKI] on Windows machines that connect via the USB port simply route the GPS information over to the [WIKI]serial port[/WIKI] so the GPS appears to be a serial GPS. They do this by installing a small driver known as a [WIKI]USB-serial port bridge[/WIKI]. In Windows, the user can then set the com port by right clicking My Computer-->Properties-->Device Manager. Look under the serial port entry and the serial port bridge should appear (if it installed correctly). Clicking on driver and then advanced allows the user to set the number of the com port to the desired port. Then that corresponding com port is entered into the configuration of the GPS in the [WIKI]navigation software[/WIKI] and the receiver is ready to go.

    On [WIKI]Apple / Macintosh[/WIKI] machines, the Unix basis for OS X utilizes a similar GPS driver but there is no serial port. Most standard USB serial ports will work with a Mac if you have a serial GPS - follow the USB unit's instructions for installation. Or, instead, the output from the GPS unit is routed to a log file with a name such as /dev/tty/GPS12. When configuring the Mac for GPS, load the driver, plug in the GPS unit to the USB port and open the Network control panel in Preferences. If installed properly, you will be informed that a new serial port is available and that you must activate it. Select "Network Port Configurations" from the drop down menu and check the box to turn it on. Configure the GPS software using this port identification.
