Summary
Sharp/NEC Ld Fa192 F projector. RS-232C serial + wired/wireless LAN (TCP) control. Binary hex command protocol with checksum byte. 53 documented commands covering power, input switch, mutes, lens control/memory, picture/volume/aspect adjust, status queries, and eco/PIP/edge-blend settings.

Actions
# Command frame format (hex). Request byte1 indicates class:
# 00h=info-query 01h=freeze 02h=basic-action 03h=extended
# Response ack byte1: 20h/21h/22h/23h = success; A0h/A1h/A2h/A3h = error (carries ERR1 ERR2).
# Checksum (CKS) = low-order byte of sum of all preceding bytes (incl. ID1 ID2 in responses).
# Fixed bytes shown verbatim from source; <DATAxx> and <CKS> are parameters/computed fields.

Notes
Binary hex protocol. Each command/request frame ends with checksum byte. Response has class-byte prefix: 2xh = success, Axh = error (carries ERR1/ERR2). Checksum = low byte of sum of all preceding bytes (responses include ID1+ID2 in sum). Error code table (ERR1/ERR2) covers unrecognized cmd, unsupported by model, invalid value, invalid input, memory errors, forced mute, no signal, power-off rejection, no authority, gain errors. Usage times updated at 1-minute intervals though queried in 1-second units. Lamp remaining life returns negative after replacement deadline exceeded.
Spec done. 53 actions, all hex payloads verbatim from source. Gaps marked UNRESOLVED (firmware, ID1/ID2 defaults, appendix value lists, voltage specs).
