Here you can enter connection information regarding your GPS receiver. Select the correct device and baud rate for your GPS if necessary. Please refer to your GPS manual for these values.
Cumulus can provide you some status information concerning your GPS reception. If you want to know what satellites are in view, where they are, how strong their signal is, or if you want to take a look at the raw NMEA stream of your GPS, use the G key or click on the GPS status indicator in the status bar. This will open a status dialog for the GPS. The dialog can be closed with the Escape key or with the close button.
Note that Cumulus will only accept GPS data sentences with a valid checksum. It is also able to process the proprietary sentences emitted by a Cambridge, Volkslogger, Flarm or LX device and to process this these data. Wind, variometer and MacCready data from such devices will be taken over automatically, if they are available. MSL and STD altitude, derived from the pressure sensor are only taken on demand.
If you use a Nokia Internet Tablet N800/N810/N900 the entry GPS Location should be your first selection unless you want to connect via your USB interface adapter to the GPS. In such a case select the device /dev/ttyUSB0. Another possibility is to select the entry BT Adapter. In this case Cumulus will scan automatically your environment for reachable GPS Bluetooth devices. If devices have been found, a combo box dialog is opened and you can select one device from the list. Cumulus tries then to open a connection to this device. If your device selection was wrong, you have to restart Cumulus.
If your device is not contained in the selection list, you can change one of the predefined entries to your need.
Some logger devices can deliver altitude values derived from a pressure
sensor. If you want to use pressure data, you have to select in the Altitude
Reference combo box the entry Pressure.
Please note! If you have selected the pressure item Cumulus
expects special NMEA records from the connected logger devices.
Otherwise you will not get displayed any altitude and variometer data!
