Variables

# Volume/Fader: 0-65535 maps to dB range (e.g., -72dB to +12dB for standard faders)
# Formula: Volume dB = MIN + (MAX - MIN)*(POSITION/65535)
# Button: 0=off, 65535=on (some buttons use negative logic, noted in controller appendix)
# Input Selector: 0=first input, 65535=last input; linear mapping via (INPUT-1)*65535/(N-1)
# Meter: Read-only, 0=-48dBu to 65535=+24dBu for main meters
# UNRESOLVED: Controller numbers vary by product model - see appendix tables (Deuce 722, Zone Mix 760/761)

Events

# Push data events emitted when parameters change (if push enabled):
# Format: #<CONTROLLER NUMBER>=<CONTROLLER POSITION><CR>
# - Emitted when control's underlying parameter changes
# - Emitted on PUR (Push Refresh) command
# - Default interval: 100ms (configurable via PUI, 20-30000ms)
# - Threshold-based: only pushes when value differs by threshold amount (default 1)
# UNRESOLVED: No explicit event names/types defined - push data is raw controller format

Macros

# UNRESOLVED: No explicit multi-step macros documented in source

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: No safety warnings, interlock procedures, or power sequencing documented in source

Notes

Protocol format: Text-based (ASCII), commands completed with carriage return (ASCII 13, hex $0D). Hex values prefixed with $. Optional parameters in [square brackets].

Controller number ranges:

Deuce 722: Controllers 1-10000
Zone Mix 760/761: Controllers 1-10000 for input processing; 2000+ for output processing; 6000+ for zone processing

Serial vs Ethernet behavior:

RS-232 and Ethernet maintain separate quiet/echo/deaf mode settings
Commands sent to one port are NOT echoed to the other
Responses sent only to the port from which command was received
Push data sent out BOTH ports in parallel
If no valid packets received, pushed data not sent until first command received

Volume dB conversion (standard -72dB to +12dB faders): Volume dB = -72 + 84*(CONTROLLER POSITION/65535) CONTROLLER POSITION = 0 → OFF (mute)

Meter dB conversion (main input/output meters): Level dBu = 72*(CONTROLLER VALUE/65535) - 48 CONTROLLER VALUE = 0 → Level dBu <= -48 dBu

RS-232 default settings: Baud 57600, Quiet Mode ON, Echo OFF

Ethernet default settings: Quiet Mode ON, Echo OFF

RS-485 control: Described as via Symetrix ARC devices, not directly via this protocol.
