||A TCP/IP Network or Internet
Options vary dependent on UDP or TCP and if TCP whether the Connection is acting as a Client or a Server.
To setup for Data Streamed over the internet use TCP Client - for an example try hd-sf.com IP 126.96.36.199 Port 9009 (see image below)
Multi-Client TCP connections are now handled. You must set the maximum concurrent connections you will allow to the same port.
||A connection made to a Windows Com
All currently enabled Serial and USB Com ports should be listed. If you do not see the Port/Device you are trying to connect to try
View > Serial Ports which will list all the Ports NmeaRouter knows about.
If you still cannot see the Port/Device, look at the windows device manager. Start > Control Panel > System > Hardware > Device Manager > Ports (Com & LPT).
Note that USB ports are allocated by the actual USB device you are using, which is set by the Device Driver supplied with the actual USB device and not by Windows. Particularly with low priced USB devices, these drivers are not always reliable and the Com port allocated to a device can change. Most USB Devices use either the FDTI chip or the Prolific chip. The FDTI appears much more reliable in particular because the Prolific chip has been extensively "cloned" and if you upgrade the driver, you may find the cloned chip stops working. For further information see Prolific and FDTI .
||Input from or Output to a File.
You cannot have the same file open for both input and output.
If Roll Over is selected (only applicable to output files), the file will be named yourname_YYYYMMDD.yourname
At Midnight a new file will be stated with the new date.
With Input files you can select the maximum rate at which the sentences will be read from the file. This allows you to slow down the output. You will also be given an option to Pause the input (re-starts from the file position when paused).

TCP Multi-Client Server (V43)
This enables you to distribute data received by one PC to multiple PC's either locally or remotely via the internet.
When you set a TCP server port (eg 11367), this port is set a a "listening" port, awaiting a TCP connection request.
If Client tries to make a connection to the Server on this port (eg 11367), the Server will "spawn" another connection.
The spawned connection inherits the routeing of the "Listening" port.
The server recommences "listening" on the port (11367) allowing it to set up another connection to a second Client, should it be requested. This will continue up to the limit of Maximum Concurrent Connection set when the Server was configured.
This enables multiple Clients to be given the same socket to connect to the Server on which to receive the data.
You you can set up another instance of NmeaRouter on the same PC to try this - set the remote host IP as 127.0.0.1 which translates to the local PC.
Routing to a Program which only accepts Serial Data - Virtual Com Ports
Some programs (note OpenCPN now accepts network data) will only accept serial data, or possibly proprietary network data such as Garmin or Json as well. These programs expect your PC to be physically connected to serial or USB port.
If you attempt to connect two programs to the same physical port (eg COM4) at the same time, your PC will prevent this, and you will receive an error message such as “port in use”.
From V46, you can overcome this problem by creating a Virtual Com Port Pair (VCP) with Connection > New > VCP > Create
You can see the created VCP with View > Serial Sockets
The Serial Socket CNCA0 is linked to COM15
A Serial Connection called OpenCPN is created using Port CNCA0
A Route is created between the incoming data (AIS Data) and OpenCPN
Data arriving on the Connection AIS Data will appear to be Output on COM15.
If the OpenCPN Chart Plotting program is started using COM15 as the Input, the AIS Data will displayed on the OpenCPN program.
For more details see Guideline on installing and connecting NmeaRouter on a Windows computer with OpenCPN or any other program only accepting Serial Data.
Remove duplicated Sentences from all Sources (V53)
The main purpose is to reduce network bandwidth when NmeaRouter is used to combine several differing Sources of data.
This filter monitors the input from all source connections. If an identical sentence is received, possibly/probably from a different source, the duplicated sentence is rejected and not passed forward to any Destination.
The previous 6 minutes of received sentences are compared with each received sentence..
Multi-part messages are subject to additional "special" handling.
To insert this filter click Configure > Filters and Tick the box.
All sentences filtered out are sent to a Demiliterized Zone (DMZ), in a similar manner to an internet router.
These sentences can be forwarded to any existing Output Connection. For example, you can set up a File Output Connection to write the duplicated sentences to a Log file.
In addition you can see the Source of the duplicated sentences by adding IEC 61162 comments to the output.
The Log File will contain the commented sentences
\c:1369230289,d:File Output,s:Home TCP*30\!AIVDM,1,1,,B,35DrjF5000Ow5M8NdHD2Mb9T0000,0*12

I intend integrating AisDecoder with NmeaRouter in the future by plugging in AisDecoder into NmeaRouter.
This requires re-writing AisDecoder as a stand alone module, with the ability to plug-in to other software.
There is a limit of 10 on most of the options. This is because I may release an unrestricted (commercial) version of NmeaRouter in the future.
