Optoma UHD SUHD Series X A Control Spec

Summary

Optoma RS-232 serial control protocol for Optoma UHD/SUHD projectors. Provides power, source, display mode, image adjustment, lamp, security, menu and remote-emulation commands plus read-back queries. Command format: ~XX{cmd} {param}\r where XX is the projector ID (00 = all projectors, 01–99 = individual). Pass response = P, fail = F.

Transport

protocols:
  - serial
serial:
  baud_rate: 9600
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none
  uart_fifo: disabled  # source: "UART16550 FIFO: Disable"
auth:
  type: none  # inferred: no auth procedure in source
# All commands are addressed by projector ID: XX=01-99 (specific) or 00 (all).
# Frame: ASCII "~XX{cmd} {param}" + CR (0x0D). Projector replies "P" (pass) or "F" (fail).

Traits

# Inferred from command examples present in source
traits:
  - powerable      # inferred: ~XX00 1/2 power on/off present
  - queryable      # inferred: ~XX121-129 read queries present
  - levelable      # inferred: brightness/contrast/volume/zoom parameterized commands present
  - routable       # inferred: source-selection commands ~XX12 / ~XX39 present

Actions

# XX = projector ID. `00` = broadcast to all projectors; `01`-`99` = specific unit.
# Source lists each enumerated variant as a separate row → each is its own action.
# `id` parameter is the projector address used in the leading ~XX field.
# Hex payloads transcribed verbatim from source. Where source carries obvious
# transcription bugs (e.g. ~XX35 uses 3036 = "06" hex, ~XX61/82/83 reuse 3030
# or 3038 hex groups) the payload is reproduced AS WRITTEN in the source -
# verifier should treat those rows as suspect.

Safety

confirmation_required_for: []
interlocks: []

Notes

• Source is a generic Optoma RS232 Protocol Function List — not specific to any single product. The model name "UHD SUHD Series X A" appears to be a scraper artifact; the source's own model-name query (~XX151 1) returns one of EP721/EP723/EP727/EP728/EW1610. Treat the model binding as UNRESOLVED until a real product is matched.
• All commands carry a 2-digit projector ID prefix ~XX. 00 broadcasts to all projectors on the bus; 01–99 address a specific unit. Each frame ends with CR (0x0D).
• Pass/Fail acknowledgement: projector replies P (pass) or F (fail) for each accepted command.
• Suspect rows in source (reproduced verbatim, flagged for verifier attention):
  • ~XX35 (Degamma) source hex row reads 7E 30 30 33 35 20 31 0D but ASCII column shows ~XX35 — opcode mismatch between ASCII and hex columns.
  • ~XX36 is reused for both Image AI and Color Temperature tables — same opcode, different logical meanings.
  • ~XX61 is reused for both PCMode (on/off) and Overscan (n=0-12) — same opcode, different logical meanings.
  • ~XX82 (Start Up Logo) On and Off rows share identical hex in source (typo).
  • ~XX83 (Screen Type) 16:10 and 16:9 rows share identical hex in source (typo).
  • ~XX77 (Security Timer) row has empty HEX Code column — payload UNRESOLVED.
  • ~XX108 1 (Lamp Hour) lists no description beyond "Lamp Hour" — likely a query-style read, but classified here as an action per its placement under "SEND to projector".

## Known Gaps

```yaml
- "model name \"UHD SUHD Series X A\" is a scraper artifact — the source is a generic Optoma RS232 Protocol Function List covering families such as EP721/EP723/EP727/EP728/EW1610. Confirm the exact product model before publishing."
- "firmware version compatibility not stated in source"
- "exact product model identifier not confirmed"
- "no multi-step sequences described explicitly in source."
- "source contains no safety warnings, interlock procedures, or"
- "firmware version compatibility range not stated in source"
- "exact product model identifier not confirmed — see Notes"
- "~XX77 Security Timer payload format not documented"
- "~XX35 hex/ASCII opcode mismatch in source needs vendor confirmation"
- "opcode reuse (~XX36, ~XX61) — disambiguation method not documented"
```
