Technical Appendix
ASCII protocol
The ASCII protocol allows SC MASTER to be conveniently
integrated into comprehensive multimedia installations con-
trolled by media control systems.
Via the serial port (RS232-IN) and ASCII commands the IR
remote control unit can be simulated. Moreover, this feature
also allows selective control of shows played back from CF
card.
No initialization is necessary before ASCII commands can be
sent to the control unit. The communications protocol is 9600
baud, 8 data bits, no parity bit and one stop bit.
ASCII command identification "a" (= 61 Hex, 97 Dec) must be
sent as first character. Command end identification "#" (= 23
Hex, 35 Dec) must be sent as last character. No spaces are
allowed. The maximum time interval between two characters
must not exceed 20 ms, otherwise the command is ignored.
Note: If you want to control the device via Wings Platinum you
can use a driver, which does not require any protocol knowl-
edge.
