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".

Spec done. All commands from source enumerated. Suspect rows (opcode reuse, hex typos) flagged verbatim with UNRESOLVED notes — no fabrication.

## 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"
```
