Extron DMS Series Control Spec

Summary

Extron DMS Series matrix switchers (DMS 1600, DMS 2000, DMS 3200, DMS 3600) are configurable crosspoint matrices supporting up to 36x36 audio/video routing. Control via SIS (Simple Instruction Set) commands over RS-232/RS-422 serial or TCP/IP (Telnet). Supports ties, presets, rooms, EDID management, I/O grouping, and front panel executive mode lockout.

Transport

protocols:
  - serial
  - tcp  # inferred from Telnet/IP control mention
serial:
  baud_rate: 9600
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none
addressing:
  port: null  # UNRESOLVED: TCP port number not explicitly stated in source (Telnet implied but not confirmed)
auth:
  type: password  # optional: device accepts commands without password unless password-protected

Traits

- routable    # inferred from tie/routing commands
- queryable   # inferred from query/read commands
- levelable   # output mute/unmute control

Notes

• SIS commands are not case-sensitive. Responses end with CR/LF.
• Tie commands !, &, % are interchangeable for tie operations (!=all, &=RGB, %=video).
• Commands can be chained back-to-back with no spaces (e.g. 1*1!02*02&).
• Default serial config: 9600 baud, 8N1, no flow control. Extron recommends keeping 9600 baud.
• Default IP: 192.168.254.254, subnet 255.255.0.0, gateway 0.0.0.0.
• Up to 200 simultaneous TCP connections (including HTTP and Telnet).
• Verbose mode 1 or 3 required for Telnet session to receive switcher-initiated change notices.
• Default connection timeout: 5 minutes. Extron recommends periodic Q command to keep connection alive.
• Rooms: up to 10 rooms, each with up to 16 outputs. An output belongs to only one room.
• Direct write of global presets should always be preceded by a clear ties command for that preset number.
• RS-422 mode available via pin 7 (RX+) and pin 8 (TX+) on the 9-pin D connector.

Verification Summary

verdict: verified

matched_actions: 101
action_count: 101
confidence: medium
summary: "All 101 action units map to SIS commands in the source, and the serial and auth transport values are supported; the TCP port is left unresolved. (8 unresolved item(s) noted in Known Gaps.)"
