Shows and sequences saved on CF card and played back via an SC Master can be remotely controlled in a variety of ways.
Via IR remote control. More information can be found in the manual for your device.
Via RS 232 command and the serial port RS 232 IN, e.g. if you want to remote-control an SC Master via a superordinated media control system. See Remote control of SC Master via serial commands
Via key or switching contact and the REMOTE socket, DATA IN/OUT socket or via SC Net REMOTE Module. This way you can use keyboards, light barriers, motion detectors, etc. for show start. See Starting shows via keyboards or switches.
Autostart after starting up the system. See Example of Automatic start from CF card
Which way you choose depends on your application and the SC Master or SD Event Control units used.
