Symetrix Jupiter 4 RS-232 / IP control commands

Summary

Symetrix Jupiter series DSP processors (Jupiter 4, 8, 12) controlled via UDP text protocol on port 48630. Human-readable ASCII commands with CR terminators. Controller-number-based addressing for faders, buttons, selectors, meters, and presets. Supports unsolicited push notifications for parameter changes.

interlocks: []
# UNRESOLVED: no safety warnings or interlock procedures found in source

Notes

All commands terminated with <CR> (ASCII 13 / hex $0D). Responses also CR-terminated.
Commands must not be split across multiple UDP packets.
Zero-termination character optional in commands; never present in responses.
Responses sent to IP and source port of last received packet; saved in non-volatile memory across power cycles.
Push data not sent until first command received (device needs return address).
Controller values are 16-bit (0–65535). Fader mapping: 0 = min, 65535 = max, linear in dB. Volume faders typically -72dB to +12dB.
Buttons use 0 = off, 65535 = on (some use inverse logic, noted per-product in Appendix).
Meters are read-only. Level mapping: 65535 = +24dBu (0dBFS), 0 = -48dBu (-72dBFS) or less.
Preset range 1–50 per control application definition.
Push interval default 100ms, adjustable 20–30000ms. Shorter intervals may degrade system performance.
Quiet mode ON and echo OFF are defaults and recommended for normal operation.
Default push state: globally enabled at power-on, but individual controllers disabled for Jupiter devices.
Source document title references "Jupiter 4, Jupiter 8, Jupiter 12" — no mention of "322 DSP Engine" in source text.
