Variables
# UNRESOLVED: no additional settable parameters found in source
Events
# UNRESOLVED: no unsolicited notifications described in source
Macros
# No RS-232 macro sequence is documented. Appendix B describes physical remote-key sequences, not serial wire commands.
Safety
confirmation_required_for: []
interlocks: []
# No RS-232 command interlocks are documented. Appendix B warns to connect the microphone before remote Self-EQ; that physical remote procedure is outside this serial command set.
Notes
This spec covers Appendix A RS-232 commands. Appendix B physical remote sequences (Self-EQ, restore defaults, video mode, serial-number display, saved-volume reset and test display) are not documented as serial wire commands and are not translated into invented RS-232 Actions.
Command format: # header, 3-4 ASCII chars command + params, $ terminator. All commands case-sensitive, CAPS ONLY.
