disc changer.
COM port 4 is to be used for connecting an Escient ETP-1500 wired touch panel, external modem or to interface with a third party control system
suchasAMXorCrestron.
If you are using both an Escient ETP-1500 touch panel and an external modem, connect the Escient ETP-1500 to COM port 3 and use COM port 4
for the external modem.
Note:YoushouldusetheEthernetcontrolsystemforcontrollingFireBallfromathirdpartycontrolsystemwheneverpossible.UsingtheEthernet
control system frees up COM port 4 for other purposes, allows much longer distances between FireBall and the control system, and provides a much
faster path for data transfer.
INTERNAL MODEM CONNECTIONS
Use of the internal modem for connecting to the Gracenote and Escient disc lookup services should only be used if a broadband connection is not
available.
