Extron DTP2 T 212 RS-232 / IP control commands

Summary

The Extron DTP2 T 212 is a 2-input HDMI switcher with DTP and HDMI outputs. This spec covers RS-232C serial control via Extron SIS (Simple Instruction Set) commands. SIS commands can also be issued via USB from the front panel Config port.

Notes

The source document consistently refers to the model as DTP2 T 212 (part number 60-1587-52). The entity in this spec is extron_dtp2_t_204. Verify the correct model designation before deploying.
SIS commands are not case-sensitive unless otherwise indicated.
Command terminator for Escape-prefixed (E/W) commands is } (soft CR, hex varies) or |; the device executes on receipt of the terminator.
Responses end with CR/LF (] = hex 0D 0A).
A pause of 10 seconds or longer between command ASCII characters causes a timeout; the command is silently aborted.
Verbose mode controls response format: mode 0 = minimal, mode 1 = verbose labels, modes 2/3 = tagged query responses (constant string + value).
CEC Communications on the HDMI output always pass through. On the DTP2 output, CEC pass-through only works when connected to a DTP2 or DTP standalone receiver; it does not pass through to IN1804, IN1808, or similar devices.
Sending a CEC command to a disabled input or output returns E14.
SIS commands can be issued via RS-232 (rear panel Remote port) or USB (front panel Config port). The Over TP RS-232 port uses a 5-pole captive screw connector; RS-232 and IR share the ground pole.

Known Gaps

- "The refined source document references the DTP2 T 212 model throughout; the device in the entity_id is DTP2 T 204. Commands and protocol parameters are sourced from the DTP2 T 212 SIS reference."
- "flow control not stated in source"
- "no persistent variable-state model documented beyond per-command query responses"
- "no multi-step macro sequences described in source"
- "no safety warnings or interlock procedures documented in source."
- "The 5V output hot plug mode documentation in the source lists values \"0 = Auto\" and \"1 = 5V always enabled (default)\" in the Symbol Definitions section, but the Command Table KEY states \"1 = Auto (5V enabled when source present with 5V), 2 = 5V always enabled (default)\" — the command table values are used here as they appear more complete."
- "Flow control (hardware/software) not specified in source."
- "USB connection parameters (e.g., virtual COM port settings) not specified in source."

Notes

The source document consistently refers to the model as DTP2 T 212 (part number 60-1587-52). The entity in this spec is extron_dtp2_t_204. Verify the correct model designation before deploying.

SIS commands are not case-sensitive unless otherwise indicated.

Command terminator for Escape-prefixed (E/W) commands is } (soft CR, hex varies) or |; the device executes on receipt of the terminator.

Responses end with CR/LF (] = hex 0D 0A).

A pause of 10 seconds or longer between command ASCII characters causes a timeout; the command is silently aborted.

Verbose mode controls response format: mode 0 = minimal, mode 1 = verbose labels, modes 2/3 = tagged query responses (constant string + value).

CEC Communications on the HDMI output always pass through. On the DTP2 output, CEC pass-through only works when connected to a DTP2 or DTP standalone receiver; it does not pass through to IN1804, IN1808, or similar devices.

Sending a CEC command to a disabled input or output returns E14.

SIS commands can be issued via RS-232 (rear panel Remote port) or USB (front panel Config port). The Over TP RS-232 port uses a 5-pole captive screw connector; RS-232 and IR share the ground pole.

Known Gaps

- "The refined source document references the DTP2 T 212 model throughout; the device in the entity_id is DTP2 T 204. Commands and protocol parameters are sourced from the DTP2 T 212 SIS reference." - "flow control not stated in source" - "no persistent variable-state model documented beyond per-command query responses" - "no multi-step macro sequences described in source" - "no safety warnings or interlock procedures documented in source." - "The 5V output hot plug mode documentation in the source lists values \"0 = Auto\" and \"1 = 5V always enabled (default)\" in the Symbol Definitions section, but the Command Table KEY states \"1 = Auto (5V enabled when source present with 5V), 2 = 5V always enabled (default)\" — the command table values are used here as they appear more complete." - "Flow control (hardware/software) not specified in source." - "USB connection parameters (e.g., virtual COM port settings) not specified in source."
