In order to establish a connection between the iSMA-B-FCU controller and iC Tool, the SOX connection needs to be opened.

The SOX function allows online programming of the iSMA-B-FCU controller (real time). The controller must be connected directly via a USB cable. The SOX button is always enabled each time the USB cable is connected directly to the iSMA-B-FCU controller and opening of any project is not required.

Opening SOX protocol

The SOX button guides the user to the next window, where the SOX protocol can be started by pressing the 'Begin Communication' button. After starting the communication to the connected controller, the User can edit or build the application inside the iSMA-B-FCU controller by using the iC Tool software.

The SOX window has the following communication parameters:

  • Port: port number (usually 1876) used by SOX protocol;
  • Begin Communication button: start SOX communication. It is recommended to open SOX communication with the iSMA-B-FCU controller before running the iC Tool software;
  • Stop Communication button: stop SOX communication.

SOX protocol console

Note: Only one instance of the SOX protocol console can be opened at a time. If the SOX button in the main application window is disabled, the SOX protocol console has been already opened, and probably it is hidden somewhere under other windows on the user's screen.

If all the above actions have been performed, the communication via SOX protocol can be established with the iSMA-B-FCU controller using the iC Tool software.
