Notes

• SIS commands are not case-sensitive unless explicitly stated (audio gain/attenuation: uppercase G for gain, lowercase g for attenuation).
• Responses terminate with CR/LF (represented as ] in command tables).
• The } character represents a bare carriage return (hex 0D) in commands.
• The • character represents a space character in command/response examples.
• Executive mode 1 locks all front panel functions; mode 2 locks mic mute and mic volume only.
• Video breakaway to HDMI/DTP inputs (3-6) only available when input is configured for analog audio.
• Program audio breakaway to HDMI/DTP inputs (3-6) only available when audio input format is set to analog.
• EDID slots 1-56 are factory presets, 57 is VGA auto-detect, 58 is HDMI/DTP auto-detect, 59-64 are user-loaded.
• Default EDID for RGB inputs: 1280x720 @ 60 Hz (slot 3). Default EDID for HDMI/DTP inputs: 720p @ 60 Hz (slot 50).
• Error codes: E01=invalid channel, E10=invalid command, E13=invalid value (out of range).
• Talk-over ducking range: 0-30 dB (default 6 dB). Threshold range: 0-30 dB (default 8 dB).
