Summary
Sharp/NEC Dd E244F is a projector controllable via RS-232C serial and wired/wireless LAN (TCP). This spec covers the binary command set documented in the Projector Control Command Reference Manual (BDT140013 Rev 7.1), including power, input switching, mutes, picture/volume/lens adjust, lens memory, and status queries.

Actions
# All command frames verbatim from source. Parameters shown as <DATA??>. Checksum
# byte (CKS) shown where the source documents it as part of the frame; for
# parameterized frames the CKS placeholder is shown since it is computed at runtime
# per the documented algorithm (sum of all preceding bytes, low-order 8 bits).

- Command framing: request header byte encodes class (
00h/01h/02h/03h), success-response headers are20h/21h/22h/23h, error-response headers areA0h/A1h/A2h/A3h. The<ID1>/<ID2>(Control ID, Model code) and trailing<CKS>bytes are runtime values per the documented checksum rule: sum of all preceding bytes, low-order 8 bits. - Checksum example from source:
20h 81h 01h 60h 01h 00h→ sum103h→ CKS03h. - Serial port uses D-SUB 9P cross cable; pin assignment documented (2↔3, 7↔8 crossed, 5=GND).
- LAN port is RJ-45; TCP port 7142 for command send/receive.
- Error responses carry ERR1/ERR2 codes (full table in source §2.4), including
02h 0Dh"command cannot be accepted because the power is off". - Multiple command sub-tables (aspect values, eco-mode values, input-terminal values, base-model-type values, sub-input values) are deferred to a source Appendix not present in the refined text; values left UNRESOLVED.

Known Gaps
- "actual marketing model name not stated in the source manual (titled generically \"Projector Control Command Reference Manual\"); model name taken from operator-provided device name. Firmware version range and exact display/light-source specs not stated."
- "flow control not stated; \"Communication mode: Full duplex\" only given"
- "response framing for variable-length fields uses <ID1> <ID2> <CKS>"
- "enum values deferred to source Appendix.\""
- "numeric ranges/default values for these variables are returned"
- "source documents no unsolicited notifications. All responses are"
- "source documents no multi-step macro sequences."
- "source documents no power-on sequencing requirements, voltage"
- "(1) precise model name (operator-supplied), (2) firmware compatibility, (3) power/voltage specs, (4) flow_control, (5) enum values for aspect/eco-mode/input-terminal/sub-input/base-model-type, (6) Control ID and Model code default values."
