Beyerdynamic MIX 10 NG2 RS-232 / IP control commands

Summary

Stereo/mic line mixer with RS-232 control. Two-byte commands wrapped in DLE-framed packets with XOR checksum. 9600 baud, 8N1, no handshake. Sub-D 9 (Pin 2=Rx, Pin 3=Tx, Pin 5=GND). DevNo=0x01 for PC→Device, 0x00 for Device→PC.

Transport

protocols:
  - serial
serial:
  baud_rate: 9600
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none
  connector: "Sub-D 9 (Pin 2=Rx, Pin 3=Tx, Pin 5=GND)"
auth:
  type: none  # inferred: no auth procedure in source

Traits

- routable  # inferred: input source selection (A1, C1)
- levelable  # inferred: volume commands (A2/A3/A6/A7)
- queryable  # inferred: inquiry commands (AF, BF)
- powerable  # inferred: switch-on status preset (B7, D7)

Actions

PC→Device frame: 10 02 01 {Len} {Cmd} {Data0} {Data1?} 10 03 {CS}. {CS} = XOR of bytes STX(02) through ETX(03) inclusive. {Len} = byte count of Cmd+Data (0x01 / 0x02 / 0x03).

  # UNRESOLVED: data byte format for D8 not detailed in source beyond "V 1.0" example

Safety

# UNRESOLVED: source contains no explicit safety warnings or interlock procedures

Notes

Frame format: DLE STX DevNo Len Cmd Data[0..1] DLE ETX CS. DLE=0x10, STX=0x02, ETX=0x03.
Checksum: XOR of bytes STX(02) through ETX(03) inclusive, excluding the leading DLE(10) and the CS byte itself.
Length: byte count of Cmd + Data (typically 0x02 or 0x03).
Volume scale (hex): 00..20 → N × (-0.5 dB); 21..40 → N × (-1.0 dB) + 16.0 dB; 41..4E → N × (-2.0 dB) + 80.0 dB; 4F..7F → -104 dB (mute).
Channel codes: 00..04 = LINE, SUB-L, SUB-R, MASTER-L, MASTER-R; 10..15 = MIC1..MIC6.
A6/A7 step direction: bit 6 of Data0 — 0=higher, 1=lower.
C8 bit fields: bit 0 = auto ducking, bit 1 = manual ducking.
Acknowledgement: device sends an ack immediately after each request.
Worked example (select CD line input = line 3): 10 02 01 02 A1 03 10 03 A0 (XOR of 02⊕01⊕02⊕A1⊕03⊕10⊕03 = A0).
