Extron DTP3 T 203 Control Spec

Summary

The Extron DTP3 T 203 is a three-input DTP/HDBT-capable switcher/extender with two outputs. This spec covers the SIS (Simple Instruction Set) command protocol exposed over the rear-panel RS-232 port (9600/8/N/1, no flow control) and the LAN port (TCP via SSH on port 22023; Telnet on port 23 is disabled by default and must be remapped via SIS). Authentication is required for both administrator and user accounts.

Transport

protocols:
  - serial
  - tcp
addressing:
  port: 22023  # SIS-over-SSH on LAN; default
serial:
  baud_rate: 9600
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none
auth:
  type: password  # admin + user accounts, default = device serial number
  username: ["administrator", "user"]  # inferred: two account types named in source
  default_password: "<device-serial-number>"  # factory default; "extron" after full reset

Notes on transport:

• Rear panel RS-232 (3-pole captive screw): Rx/Tx/G; 9600 baud, 8 data bits, no parity, 1 stop bit, no flow control.
• LAN: open TCP socket to port 22023; device sends a copyright banner (product name, firmware version, part number, date/time); user then enters administrator or user password.
• Telnet on port 23 is disabled by default; enable with E Z23PMAP }, disable with E Z0PMAP }.
• Idle TCP connection times out after 5 minutes (configurable); use the Q (query) command to keep alive.

Traits

- powerable       # power toggle described (RPWR, remote 48 VDC)
- routable        # input select, auto-switch modes
- queryable       # extensive status query commands
- levelable       # inferred: not applicable - no level commands in source

Safety

confirmation_required_for:
  - full_factory_reset
  - reset_network_settings
  - partial_factory_reset
interlocks: []
# UNRESOLVED: source documents no explicit safety interlock procedures; only "do not tin the wires" pin-out note

Notes

• Symbols in source: } = soft carriage return (no LF). Pressing <Enter> (CR+LF) also accepted.
• All SIS responses terminate with CR/LF (]).
• Command character pause of 10+ seconds between ASCII chars causes a silent timeout/abort.
• 5-minute idle TCP timeout (configurable). Extron recommends periodic Q queries to keep alive.
• Telnet port 23 is disabled by default; remap via SIS to enable. SSH port 22023 is the primary control channel.
• Default passwords: device serial number for both user and administrator; full factory reset reverts both to extron.
• Verbose modes 2/3 cause the device to push change-notice messages to the socket; required for unsolicited event handling.

matched_actions: 113
action_count: 113
confidence: medium
summary: "All 113 spec actions matched verbatim in source. Transport (9600 baud, 8-bit, TCP port 22023) confirmed. (3 unresolved item(s) noted in Known Gaps.)"

Known Gaps

- "firmware version not stated; verified against source revision DTP System User Guide 68-3702-01 Rev. F 12 25"
- "source documents no explicit safety interlock procedures; only \"do not tin the wires\" pin-out note"
- "firmware version range compatibility not stated; baud rate enumerations beyond Port 1 (fixed 9600) not tested by spec author."
