External Control Interface Specifications
All FireBall products with external control capabilities can be controlled using either an RS232
or Ethernet connection. If the control system has an Ethernet connection then it is highly
recommended to use Ethernet because of the much higher transfer rate of the data. It is also
possible to control multiple FireBall units with a single Ethernet port on the control system.
The FireBall command and control protocol is identical when used with either RS232 or
Ethernet.
RS232 Control Setup
Any of the four RS232 ports on the back of the FireBall can be configured as the external
control port but it is standard to use the highest number port. By default, no RS232 port is
configured for external control. Use the FireBall TV user interface to select which RS232 port
will be used for control. With the FireBall TV interface displayed, press the Setup button on the
remote and then navigate to and select External Control, IR and Serial, and then Serial Control
COM port. Use the spin control to select which COM port to use and then select save. The
FireBall RS232 port selected for external control is set to 9600, N, 8, 1 and these parameters
cannot be changed.
A female-to-female DB9 null modem cable is then used between the FireBall RS232 port and
the control system.
DB-9 Pin Configuration:
Pin 2 to 3
Pin 3 to 2
Pin 5 to 5
Serial Parameters: 9600, N, 8, 1
Baud Rate: 9600
Parity: None
Databits: 8
Stop Bits: 1
Flow Control: None
Ethernet Control Setup
The Ethernet port on the FireBall is automatically configured for external control using the
FireBall’s IP address and port 251 (0xFB ;) on the same subnet. The FireBall uses a Dynamic
IP address by default. The Dynamic IP address can be found using the
Setup / Utilities/
System Information menu on the TV UI. However, it is highly recommended to set the
FireBall to a Static IP address when using Ethernet for external control because the IP address
of the FireBall must be hard coded in the control system program and could change if set to
Dynamic.
Use the FireBall TV user interface to set the FireBall Ethernet port to a Static IP address. With
the TV user interface displayed, press the Setup button on the remote, navigate to and select
