Rather using USB/RS-232 for one application only, this tool will permit to connect many application to the Velbus bus.
PB_Velbus-server must be connected to the USB/RS-232 port. Then, it open a TCP port and listen to it. Each time a Velbus frame is received, it’s send out all TCP connexions. If an application send a frame via TCP, all other applications connected receive it too… and of course, PB_Velbus-server send it to Velbus bus through USB/RS-232.
The graphical interface take little ressources and show every frames (and direction). Sometime, the application is able to comment the frame (it find the function and show some parameters like temperature or module name).
