Shure MXW APXD2 neXt2 Control Spec

Summary

Shure MXW neXt 2-channel access point dock supporting wireless microphone transmitters (bodypack, handheld, boundary, gooseneck). Controlled via TCP/IP on port 2202 using ASCII command strings (GET/SET/REP pattern). Acts as gateway for transmitter commands; commands sent to MXWAPX IP address are forwarded to linked transmitters.

Transport

protocols:
  - tcp
addressing:
  port: 2202
auth:
  type: none  # inferred: no auth procedure in source

Traits

- queryable       # GET commands for device state, firmware, serial, channel status
- levelable       # audio gain control (INPUT_CH_GAIN, OUTPUT_CH_GAIN, AUDIO_GAIN)
- routable        # audio routing via REMOTE_LINK, mute states

Variables

# Audio gain, mute, and routing parameters are settable via Actions.
# Battery, device ID, channel name, meter rate, operation mode, and LED status
# are all readable and settable via GET/SET/REP pairs.
# No discrete variable-only parameters identified beyond those in Actions/Feedbacks.

Macros

# No explicit multi-step macros documented in source

Safety

confirmation_required_for:
  - REBOOT  # no acknowledgement sent; device restarts immediately
interlocks: []
# UNRESOLVED: no safety warnings, interlock procedures, or power-on sequencing
# requirements stated in source

Notes

• Transmitter commands are sent to the MXWAPX IP address; the MXWAPX forwards to linked transmitter.
• MXW neXt supports MXW Legacy command strings except where noted.
• MXW neXt transmitters do not support Mic Identify (channel index on FLASH returns ERROR).
• Metering is OFF (00000) when device is offline, out of range, or first powered on.
• Setting transmitter to OFF yields UNKNOWN on subsequent status queries.
• All messages use ASCII-7 printable characters.
• LED_STATUS requires External Mute preference set in control software or command returns ERR.
• REBOOT command sends no acknowledgement.
• INPUT_CH_GAIN index 41 = analog input (APXD2 only); index 51 = USB input.
• OUTPUT_CH_GAIN index 41 = analog output (APXD2 only); index 61 = back-channel audio.
• Gain encoding: y = gain × 10 + 1100 (range 0–1400 = -110.0 dB to +30.0 dB).
• Legacy AUDIO_GAIN encoding: z = gain + 25 (range 000–040 = -25 dB to +15 dB).
