RS-232 CONNECTIONS
External disc changers are controlled via two-way serial protocols using RS-232 serial cables. You should use COM ports 1,2, and 3 for each external
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.
IR CONNECTIONS
The direct IR input jack on the back panel of the FireBall is for controlling FireBall from a wired IR distribution system such as a Xantech system.
This connection must be an IR signal with a 36kHz carrier using an 1/8” mono or stereo connector.
The IR input jack provides 12V power. This means that you can directly connect a 12V IR receiver (like the Xantech series 291 units) to the FireBall
using a 1/8” stereo connector.
