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.
