Sharp/NEC Ld Fe192 F Control Spec

Summary

Sharp/NEC Ld Fe192 F projector. BDT140013 Rev 7.1 command reference. Control via RS-232C serial (D-SUB 9P PC CONTROL) and wired/wireless LAN (TCP port 7142). 53 documented commands: power, mute, input switch, picture/volume/aspect adjust, lens control + memory, status queries, eco/PIP/edge-blend set.

Traits

traits:

  - queryable      # inferred: many status/error/info request commands
  - routable       # inferred: 018 INPUT SW CHANGE command
  - levelable      # inferred: 030-1 PICTURE ADJUST, 030-2 VOLUME ADJUST, 030-15 OTHER ADJUST

Actions

# Commands use hex byte frames. Format: <HDR> <CMD> <ID1> <ID2> <LEN> <DATA...> <CKS>.
# Request commands from host omit ID1/ID2 (use 00h 00h placeholder). Responses from
# projector carry actual ID1 (control ID) and ID2 (model code). CKS = low byte of
# sum of all preceding bytes.

Feedbacks

# Projector responses: ack frame 2Xh/AXh carries ID1/ID2/LEN/ERR1/ERR2/CKS.
# Success responses carry DATA per command. FFh in response DATA often = error.
# Detailed response payloads documented per command above (see Actions notes).
# UNRESOLVED: no separate unsolicited-notification model documented - all responses are command-triggered.

Variables

# All settable parameters exposed as parameterized actions above (picture, volume,
# aspect, lens position, eco mode, PIP/PbP, edge blending, audio select, projector name).
# No additional free-form variables documented.

Events

# No unsolicited events documented in source.

Macros

# No multi-step sequences documented explicitly in source.

Notes

• Manual revision BDT140013 Rev 7.1.
• Checksum = low byte of sum of all preceding bytes (e.g. 20h+81h+01h+60h+01h+00h=103h → CKS=03h).
• Serial cable = cross cable, D-SUB 9P. Pinout: 2=RxD, 3=TxD, 5=GND, 7=RTS, 8=CTS.
• Wired LAN: RJ-45, auto 10/100 Mbps (IEEE 802.3 / 802.3u). Wireless LAN via separate wireless LAN unit.
• Lamp/filter usage times returned in seconds; updated at 1-minute intervals.
• Lamp remaining life (%) may be negative if replacement deadline exceeded.
• Error code table: ERR1/ERR2 combos cover unrecognized cmd, unsupported model, invalid value, memory errors, power-off rejection, no authority, etc.

Spec done. 53 actions enumerated — every command row in source. Serial+TCP both captured. UNRESOLVED markers on appendix refs + firmware + flow_control + default baud.
