NOVA OPERATION 45
SHOW RESTART
If you hold the Forward push-button down for a period exceeding 2 seconds, the Show will reset to Cue 1. Since the Scenemaster
cycles back from the last cue to the first cue there will be a smooth restart to the Cue 1 state.
REMOTE INPUT SPECIFICATIONS
The remote control input requires a stereo phone jack with the following connections:
TIP Forward connection
RING Reverse connection
SLEEVE Common connection (chassis earth)
The Forward, Reverse and Restart commands are given to the Scenemaster as follows:
Forward Cue Connect tip to sleeve for a period of not less than 10 milliseconds and no greater than 1 second.
Reverse Cue Connect ring to sleeve for a period of not less than 10 milliseconds and no greater than 1 second.
Restart Show Connect tip to sleeve for a period of 3 seconds.
The sleeve is connected to the Scenemaster chassis and is at Earth potential. The Forward and Reverse inputs have an internal
pull-up resistor of 4700 ohms to 5 volts, and hence may be safely activated by any external switch such as a push-button, relay
contact, or computer logic output including TTL, LS-TTL, CMOS, NMOS, open collector transistor output, or any other device
which can sink 1 milliamp. Connection diagrams are given in the appendix at the end of this manual.
