Summary

The Extron DA2 HD 8K AE and DA2 HD 8K AI are 1-input / 2-output HDMI distribution amplifiers supporting 8K signals up to 40.1 Gbps. This spec covers SIS (Simple Instruction Set) commands over the front panel USB-C configuration port, including signal/HDCP status queries, video mute, output HDCP mode, TMDS format, color bit depth, 5V hot-plug mode, HDCP notification, audio mute, analog audio gain, audio input format, and unit identity.

Notes

SIS commands sent over front panel USB-C configuration port. Responses terminate with CR/LF (↵). Command characters can be upper or lower case. 10-second inter-character timeout aborts command. Device power-up message: © Copyright 2024, Extron, DA2 HD 8K AE (AI), V.xx, 60-xxxx-01↵. Error codes: E10 (invalid command), E13 (invalid parameter), E14 (invalid for this configuration), E17 (invalid command for signal type). DA2 HD 8K AE differs from AI: AE extracts analog audio from HDMI; AI embeds analog audio onto HDMI. Some commands (analog gain, audio input format) are AI-only; some (audio output mode) are AE-only.

summary: "All 51 spec actions matched literal SIS commands in source; transport parameters are Extron SIS standard; full command catalogue represented. (3 unresolved item(s) noted in Known Gaps.)"

Known Gaps

- "no IP/TCP transport documented in source. Spec covers USB-C SIS only."
- "no safety warnings or interlock procedures documented in source."
- "no IP/Ethernet control protocol documented in source. Known protocol field \"TCP/IP\" in input likely incorrect — source covers USB-C SIS only. Firmware version not stated. Port number, baud rate, parity inferred from Extron SIS convention (not stated in this excerpt)."
