Data stream manager 

The data stream manager provides you with the ability to create mappings between two endpoints on the router. These endpoints 
may be physical or virtual, for example, a serial port connected to the router

’s USB port could be configured as an endpoint or you 

could configure a TCP Server as an endpoint. You can then configure a virtual data tunnel or “stream” between the endpoints.

 

The data stream manager provides a wide range of possibilities and expands upon simple PAD functionality to include the 
forwarding and translation of data between any of the endpoints. In each case, the logical flow of the stream is from Endpoint A to 
Endpoint B. 
 
Customers interested in developing their own applications to create custom endpoints and streams can contact NetComm Wireless 
about our Software Development Kit. 
 

Endpoints 

The first thing to be done in order to create a data stream is to define the endpoints. There are 6 types of endpoint that may be 
configured: 

 

Serial port (generic) 

 

TCP Server 

 

TCP Client 

 

UDP Server 

 

UDP Client 

 

User defined executable 

 

Circuit switched data (CSD) 

 

TCP connect-on-demand 

 
To access the Endpoints page, click on the Services menu at the top of the screen, click on the Data stream manager menu then 
click on the Endpoint menu item on the left.
