Ashly Audio Nxe1 52Bd Control Spec

Summary

Binary control protocol for the Ashly Audio Nxe1 52Bd, a network-capable DSP audio processor in the ne/Pêma series family. The protocol uses MIDI SysEx-style framing (F0…F7) with a 6-byte fixed header (F0 00 01 2A 06 00) for standard messages and a Wall Remote variant (F0 00 01 2A 0C 00). All byte values are hexadecimal, transmitted as raw bytes (not ASCII). Commands cover preset recall/save, channel gain, mute, EQ filters, gates, compressors, auto-levelers, duckers, mixers/routing, HPF/LPF, delay, polarity, preamp, metering, and data upload/download.

Transport

protocols:
  - tcp
  - serial
addressing:
  port: null  # UNRESOLVED: TCP port not stated in source
serial:
  baud_rate: 9600  # source: "Baud rate is 9600bps for all products, except the ne24.24M"
  data_bits: 8  # source: "8 Data Bits"
  parity: none  # source: "No Parity"
  stop_bits: 1  # source: "1 Start Bit ... 1 Stop Bit"
  flow_control: null  # UNRESOLVED: flow control not stated in source
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - queryable  # inferred: data request, meter request, preset names request, WR inquiry commands
  - levelable  # inferred: gain, mixer fader, preamp gain commands
  - routable  # inferred: mixer message with routing enable/disable

Actions

# All byte values are hexadecimal. Channel encoding:
#   Inputs:  00-3B = Inputs 1-60
#   Outputs: 40-7B = Outputs 1-60
# Preset encoding: 00 = preset 1, 01 = preset 2, 02 = preset 3, ...
#
# Standard header: F0 00 01 2A 06 00 {msg_type}
# Wall Remote header: F0 00 01 2A 0C 00 {msg_type} 00 01
#
# Message types 06 thru 1A, WR-0A, WR-0B, WR-0C are always echoed back from unit to confirm reception.
# Message types 06, 08, 09 are ne24.24M only.

Notes

• All byte values in this protocol are hexadecimal, transmitted as raw hex bytes (not ASCII characters). In Crestron, use \x prefix (e.g. F0 = \xF0).
• Standard message header: bytes 1-6 = F0 00 01 2A 06 00. Wall Remote messages use F0 00 01 2A 0C 00 (byte 5 = 0C) plus 2 WR identification bytes (00 01) before payload data.
• Message types 06, 08, 09 are ne24.24M only — not supported on other ne/Pêma products including the Nxe1 52Bd.
• Message types 06 thru 1A, WR-0A, WR-0B, WR-0C are always echoed back from the unit to confirm reception.
• Message types 00, 02, 04, WR-03, WR-05, WR-07 invoke a specific response message from the unit.
• Non-applicable or invalid messages are echoed back as received with no other action.
• All products except the ne24.24M require associated DSP functions to be populated via Ashly software for each message type.
• ne24.24M power-on baud rate is 38,400 bps; it changes to 9,600 bps when ten F9 bytes at 9,600 bps are received. All other products default to 9,600 bps.
• Additional propagation delay of 1.46 ms from any input to any output due to digital converters and DSP.
• Gain Word: 14-bit integer, decimal range 7692-8312 = -50 to +12 dB in 0.1 dB steps (8192 = 0 dB). Byte N = gainWord / 128 (bits 13-7); byte N+1 = gainWord AND 127 (bits 6-0).
• Sample gain transmit for Input 7 at -50 dB: F0 00 01 2A 06 00 0C 06 3C 0C F7 (hex) or 240 0 1 42 6 0 12 6 60 12 247 (decimal).
• Meter level byte format: 0CLLLLLL — bits 5-0 = dBu level (0 = <-42 dBu, 1-3F = -42 to +20 dBu), bit 6 = clip (0 = not clipped, 1 = clipped).
