Extron DTP CrossPoint 84 control commands

Summary

The Extron DTP CrossPoint 84 is an 8x4 matrix switcher with integrated audio DSP, scaling output, and HDBaseT/HDMI I/O. This spec covers the Extron Simple Instruction Set (SIS) used to control the device over RS-232 (Remote captive-screw port) and TCP/IP (Ethernet, port 23). It enumerates matrix tying, EDID management, HDCP control, video/audio mute, scaler output, audio DSP, and configuration commands.

Transport

protocols:
  - serial
  - tcp
addressing:
  port: 23

  baud_rate: 9600
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none
auth:
  type: password  # source describes optional administrator and user passwords (up to 12 alphanumeric chars)

Traits

- routable  # inferred from input/output tying and audio routing commands
- levelable  # inferred from scaler brightness/contrast and DSP gain commands
- queryable  # inferred from extensive "View" / "Read" commands throughout

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: source does not document explicit safety warnings, power-on sequencing, or destructive

# confirmation in the source.

Notes

SIS commands use } (carriage return, hex 0D) as the line terminator for write commands and ] (CR/LF, hex 0D 0A) terminates responses.
For URL-encoded commands, use | in place of } (carriage return). For web/browser SIS, use W in place of E (escape, hex 1B).
The pipe character | and other special characters are rejected inside names, passwords, and file names: + ~ , @ = ' [ ] { } < > ' " ; : \ ? (space allowed in names only).
Default IP address: 192.168.254.254, subnet 255.255.0.0, gateway 0.0.0.0. IPCP Pro 350 variant uses 192.168.254.250 / 255.255.255.0.
Default TCP connection timeout: 5 minutes. Maximum 200 simultaneous TCP connections.
Configurable host RS-232 baud rates: 9600 (default), 19200, 38400, 115200. Data bits 7 or 8 (default 8). Parity odd/even/none/mark/space (default none). Stop bits 1 or 2 (default 1). Flow control hardware (RTS/CTS), none, or software (XON/XOFF).
Ethernet: 10Base-T / 100Base-T, half- and full-duplex.
Passwords (admin and user) are optional; if set, login prompt is sent on TCP connect. Up to 12 alphanumeric characters.
Verbose mode levels 0/1/2/3 control response verbosity globally; many commands have alternate verbose response forms listed in the source.
Scaler adjustment commands (BRIT, CONT, HDET, HCTR, VCTR, HSIZ, VSIZ, ASPR, OSCN, TEST, SSAV, RATE, AMEM, XIMG) apply only to TP/scaled outputs (X1( = 03 or 04) and insertion outputs; the two mirror HDMI outputs (1, 2) do not have scaler adjustments per the source variable X1( definition.
DSP object IDs are organized into named blocks (A line inputs, B mic inputs, D virtual returns, E expansion inputs, F post-matrix gains, G/H/I/J/M/N mixer blocks, K line output gains). See source for the full ID range table.
Mic input object IDs 40000-40003 support phantom power via the E Z ... AU } command family.
DSP level values use 0.1 dB increments; valid range depends on object class (e.g. line input gain -180..+240, mic gain -180..+800, line trim -120..+120, line output gain -1000..0).
System status (S) reports voltage, internal temperature (C), and two fan RPMs.
HDCP status: input response codes 0=no source, 1=HDCP-compliant, 2=non-compliant; output codes 0=no monitor, 1=HDCP-compliant, 2=non-compliant.
E ZXXX } (system reset) clears all ties and presets. E ZQQQ } also clears IP to defaults. E ZY } resets everything except IP/unit name/DHCP/port mapping (recommended after firmware update).
Front panel 1X/2X lock modes do not disable RS-232/TCP SIS control per the source description; they only restrict front panel access.

Known Gaps

- "USB Configuration port protocol is for firmware/upload only and is not covered. Web browser SIS-over-HTTP is mentioned for file directory queries but not detailed as a control surface."
- "source does not document explicit safety warnings, power-on sequencing, or destructive"
- "web browser SIS-over-HTTP is mentioned for file directory responses but not detailed as a control surface; no full HTTP path/method catalogue given."
