EXTERNAL CONTROL
COMMANDS
Within this chapter, there are two types of external control
commands that are described: Visual Circuits Corporation (VCC)
control commands and Laserdisc emulation (LDV) control
commands. Please note that the VCC control commands are
proprietary in nature, and therefore are not designed to be mixed
with LDV control commands. Doing so, could cause inconsistent
results and is not recommended.
The following list of commands may be sent via RS232 or TCP/IP
to Firefly to direct playback. Any standard show control system or
ASCII generating control program may be used. For RS232 it is
recommended to use a null modem cable. For TCP/IP connections
consult the control device specification to see if a cross over
network patch cable is required.
Connecting via RS232
❏ The RS232 9-pin D-sub connector is located on the back of
the Firefly between the audio connectors and the USB
connectors.
❏ Configure the Firefly Control Settings (see Control Settings
on page 75) to be compatible with your show controller.
Connecting via TCP/IP
❏ Set “Accept TCP/IP” to “Yes” within the Firefly Control
Settings screen. This allows anyone on the network to send
commands to the Firefly if they know its network address.
❏ The TCP/IP (ethernet) connector is located on the back of
the Firefly under the Video In connector, to the right of the
RS232 connector.
❏ Configure the network settings (see the section on Network
Settings on page 77 for details on how to do this).
❏ Connect to port 2180.
