Socket Server Port

Syntax:
<URL>/?socP=<value>
Parameters:
<URL>: host name or IP address to the installed EMU hardware
<value>: is the remote port number of the socket listener
Default:
By default the port number is 80

Example:
http://emu.ansari.de/?socP=8182

Description

Communication with the hardware is based on two simultaneous paths. One path is served by the local web server in the hardware to create the user interface pages on a browser using the HTTP protocol. On the other hand a second channel serves all live data, dynamically shown in the user interface, without the need to load the web page every time. The data values on the page, which magically gets updated in behind are served via a socket server in the hardware. 

In the EMU hardware the web server and the socket server are servicing from same IP address and port. Since web services generally use port 80 as default port, the socket server in EMU uses also the same default port 80, but there is no force to run the socket server on the same host as the web server is running and neither the same port. 

So, whenever the socket server ist not listening to port 80, then the port number of the remote socket listener can be set with the socP command.

The remote socket listener is the server, which provides the user interface with the live hardware monitoring data. Additionally any hardware configurations to the hardware are also communicated over this channel.
