Feedbacks

# Response framing (per source section 2.3): success response echoes command with high bit set on
# first byte (e.g. POWER ON -> A2h 00h <ID1> <ID2> 02h <ERR1> <ERR2> <CKS>). Data-bearing success
# prefixes first byte with 20h/22h/23h depending on command class. Failure response sets top nibble
# to Axh and carries ERR1/ERR2 per source section 2.4 error code list.
# Each query action above documents its specific return payload in `notes`.

Variables

# Settable parameters not modeled as discrete actions are covered by ADJUST-family actions
# (030-1 PICTURE, 030-2 VOLUME, 030-12 ASPECT, 030-15 OTHER, 053/053-2 LENS) and SET-family
# actions (098-8 ECO, 098-45 NAME, 098-198 PIP, 098-243-1 EDGE BLEND, 319-10 AUDIO SELECT).

Events

# Source describes no unsolicited notifications. All responses are command-driven.

Macros

# Source describes no explicit multi-step sequences.

Notes

  • Source: "Projector Control Command Reference Manual" BDT140013 Rev 7.1.
  • Frame layout: <CMD> <SUB> <ID1> <ID2> <LEN> <DATA...> <CKS>. Checksum = low byte of sum of all preceding bytes (per source section 2.2 / example on p.10).
  • Error response codes documented in source section 2.4 (ERR1/ERR2 combinations, e.g. 02h/0Dh = "command cannot be accepted because the power is off").
  • Many commands (shutter, lens family, lamp adjust, edge blending, PIP/PbP) are projector-oriented; E244F Bk is a desktop monitor. Per-command applicability not stated in source.

Known Gaps

- "source title is generic \"Projector Control Command Reference Manual\" (BDT140013 Rev 7.1). Many commands (shutter, lens, lamp, edge blending) are projector-only — not applicable to E244F Bk monitor. Model-fit per-command unverified. Firmware version not stated."
- "source does not name E244F Bk; model-fit per-command unverified."
- "firmware version compatibility not stated in source."
- "full input-terminal value list (DATA01 of 018, 319-10) referenced to \"Appendix Supplementary Information by Command\" not present in refined source."
- "full aspect value list (030-12 DATA01) referenced to appendix not present in refined source."
- "full eco mode value list (097-8 / 098-8 DATA01) referenced to appendix not present in refined source."
- "sub input setting value list (097-198 / 098-198) referenced to appendix not present in refined source."
- "base model type value list (078-1, 305-1) referenced to appendix not present in refined source."
