OCENS Mail Feature – GPS
OCENS Mail includes a powerful GPS repeater
With the GPS repeater functionality of OCENS Mail, GPS informaton can be imbedded in your email headers, sent into tracking services such as OTrak, and be used to supply data to your other navigation software or connected devices.
“Enable GPS input” must be checked before any options in this dialog can be configured. Once enabled Wireless Email Gateway must be configured to read GPS data from either a physical COM port or from a network TCP/IP socket or port.
To read GPS data from a physical port select the “GPS on physical port” box, this will enable the Port and Baud pull down lists. The Port pull down list contains a list of all the physical COM ports on the system, select the COM port which corresponds to your GPS. Next, from the Baud pull down list, select the baud rate at which the GPS has been configured. By default most NMEA 183 devices (i.e. your GPS) use 4800 baud for this setting.
The Wireless Email Gateway should now be configured to read GPS data, to confirm that GPS data is streaming into your system hit OK to return to the main screen. Then observe the state of the GPS icon on the Toolbar, if all is well you should see a green status icon. See the GPS section under toolbars for a description of the different states of the GPS icon.
Alternately, to read GPS data over the local area network, select “GPS on TCP port”. This selection enables the entry of a host by either name or IP address and a TCP port number. The host and port number must be entered as hostname:port where hostname is the name or the IP address of the computer hosting the GPS and port number is the TCP port used to repeat the data.
Using at TCP port for GPS data allows one to configure a GPS on a remote computer interconnected to the Wireless Email Gateway machine via a LAN. The remote computer could, for example, be running the Wireless Email Gateway configured to read GPS data from a local COM port and repeat it to a TCP port (see below). As long as the remote Wireless Email Gateway is repeating data to the same TCP port that is being used by the local Wireless Email Gateway, the local Wireless Email Gateway will read the data and optionally repeat it to local COM ports.
Repeat GPS output
The GPS repeater is a very powerful tool which allows multiple applications running on a local computer to access one GPS. This allows you to repeat the GPS data stream out to two additional virtual com ports as well as another network port. For example, the repeater can be used to configure Wireless Email Gateway not only to read the GPS from a physical serial port for vessel tracking but to also configure an electronic plotting program such as MaxSea, Nobeltec, or others.
Both “Repeat GPS output…” check boxes are used to enable the repeating of physical GPS data to virtual COM ports or to a network TCP port.
When enabled, Repeat GPS output to COM port, will create a new COM port on the local machine and repeat GPS data to it. To enable this feature place a check mark next to the option and then assign a COM port to the new (to be created) device.
Repeat GPS to network port creates a socket or TCP port on the local machine which can be used by network aware applications (such as the Wireless Email Gateway) to read GPS data over a network.
The enable logging functions are used to debug your GPS connection. Enable logging will create debugging information in the main status window. The Wireless Email Gateway will inform you of failed COM port creation as well as other errors which might help isolate a GPS problem.
The “Dump NMEA data…” option configures the Wireless Email Gateway to dump raw NMEA sentences to the status window. Enabling this feature results in a large amount of text being displayed in the primary status window. You should only use this function if you want to see the raw data being generated by the GPS.
