class SummitConnect():
    """ This class provides an interface to Extron Unified Communications solutions.

    Note: 
        - System limits 15 SummitConnect clients per system.

    ---

    Arguments:
        - Hostname (string) - Hostname of the host computer. Can be IP Address.
        - IPPort (int) - IP Port the software is listening on (default is 5000)
    
    Note: 
        - Only one object can be instantiated for a given Hostname or IP Address.
    
    ---

    Parameters:
        - Hostname - Returns (string) - Hostname of the host computer `Note: If unavailable, returns the IP Address.`
        - IPAddress - Returns (string) - IP Address of the host computer
        - IPPort - Returns (int) - IP Port the software is listening on (default is 5000)
        - ListeningPort - Returns (int) - IP Port this SummitConnect instance is listening on for received data
    
    ---

    Events:
        - Connected (Event) Triggers when communication is established. The callback takes two arguments. The first one is the SummitConnect instance triggering the event and the second one is a string ('Connected').
        - Disconnected (Event) Triggers when the communication is broken. The callback takes two arguments. The first one is the SummitConnect instance triggering the event and the second one is a string ('Disconnected').
        - ReceiveData (Event) Receive Data event handler used for asynchronous transactions. The callback takes two arguments. The first one is the SummitConnect instance triggering the event and the second one is a bytes string.

    ```
    from extronlib.software import SummitConnect
    ConferencePC = SummitConnect('192.168.1.110')
