What About CAD Systems?
If the dispatch center is already using a CAD system, then it is likely that the control
functions for the FSA system will be integrated into the CAD system rather than setting up
two console systems at each operator position.
The computer that acts as the core of the CAD system will communicate with the FSA
Server in one of two ways, depending on the protocol used.
If the CAD computer will connect with the FSA system by means of a dedicated serial
port, then the Model 26 Serial CAD protocol is used. This port will be one of the first four
COM ports on the FSA Translator PC.
If the two servers will communicate with each other over the Ethernet network used to
connect the servers with the rest of the FSA system, then the XML CAD Interface
protocol is used.
