Sharp PN-LC862 RS-232 / IP control commands

Summary

Sharp Big Pad touch display (xxLWxxxH / PN-LW H series). External control via Sharp "N-Format" binary protocol over RS-232C (9600 8N1) and LAN (TCP, port 7142 fixed). Source document is the PN-LC862/LC752/LC652 N-Format command manual (Rev.1.0) used as the closest available protocol proxy; the PN-LW H series shares the same N-Format control family.

Transport

# Uniform packet framing for ALL commands (applies to every action below):
#   Header: SOH(01h) '0'(30h,reserved) Destination(41h='A' for Monitor ID 1, or 2Ah='*' broadcast) Source(30h='0') MessageType(1 ASCII) MsgLength(2 ASCII hex chars)
#   Message: STX(02h) <body> ETX(03h)
#   Check code: BCC = XOR of all bytes from reserved(30h) through ETX(03h) inclusive, encoded as 2 ASCII hex chars
#   Delimiter: CR(0Dh)
# Monitor ID fixed = 1 on this device (Destination byte = 41h 'A'). Byte values in the message body are ASCII-encoded hex char pairs (e.g. byte 3Ah -> '3''A').
# MessageType codes: 'A'=Command, 'B'=Command reply, 'C'=Get parameter, 'D'=Get parameter reply, 'E'=Set parameter, 'F'=Set parameter reply.
# Timing (sec 3.3): controller MUST wait for reply before next command; after Power On/Off reply wait 15s, after Input Change reply wait 10s.
protocols:
  - tcp
  - serial

Traits

# - powerable    (power control + power status read present, sec 7)
# - queryable    (Get parameter + power status + serial/model name read present)
# - levelable    (audio speaker volume adjust present, op 00h/62h)

Actions

# command: field holds the message BODY (STX ... ETX) verbatim from source.
# Wrap each body with the uniform header/BCC/CR framing documented in Transport.
# Monitor ID = 'A' (ID 1, fixed). MsgLength: Get-param body=6 bytes -> '06'; Set-param body=10 bytes -> '0A'.

Notes

Source = Sharp "External Control" N-Format manual Rev.1.0 for PN-LC862/LC752/LC652 (dated 2023-02-27). Used as protocol proxy for xxLWxxxH (PN-LW H Big Pad series); PN-LW H shares the Sharp N-Format control family but no PN-LW H-specific manual was located (see recovery notes).
Monitor ID is fixed at 1 on PN-LC862/LC752/LC652; device accepts Destination byte 41h ('A', ID 1) or 2Ah ('*' broadcast) only.
BCC (Block Check Code) = XOR of all packet bytes from the Reserved byte (30h) through ETX (03h) inclusive, rendered as 2 ASCII hex chars. Example in sec 4.3: body STX-'0'-'0'-'1'-'0'-'0'-'0'-'6'-'4'-ETX with header 30 41 30 45 30 41 yields BCC 77h.
All numeric fields in message bodies are ASCII-encoded hex char pairs (e.g. byte 0Bh transmitted as ASCII '0','B' = 30h,42h). Max single write/read data length = 32 bytes (sec 7.2/8.1 notes).
Serial-number and model-name reply payloads are double-encoded: ASCII-hex char pairs decode to hex byte values, which themselves are ASCII characters of the final string (sec 8.1/8.2 step examples).
OP code 00h/8Dh (TV Audio Mute): value 00h is "unmute (Set only)"; 01h mute; 02h unmute; >02h ignored.
Internal PC commands (10h/C2h START UP PC, 10h/C3h FORCE QUIT) imply an integrated PC option; presence on PN-LW H variants UNRESOLVED.

(5 unresolved item(s) noted in Known Gaps.)" ``` ## Known Gaps ```yaml - "source manual covers PN-LC862/LC752/LC652 (direct predecessor). PN-LW H series (PN-LW861H/LW751H/LW651H/LW551H/LW501H/LW431H) not named in source; N-Format compatibility inferred from shared Sharp display family. No PN-LW H-specific manual located." - "flow control not stated in source" - "source documents no multi-step macro sequences. Sec 6 shows a typical Get->Set->confirm procedure" - "no hardware interlock / power-sequencing warnings beyond communication timing stated in source." - "(1) PN-LW H series not explicitly named in source — N-Format compatibility inferred from shared Sharp display family. (2) Flow control line not specified. (3) Firmware version compatibility not stated. (4) Whether all OP codes (esp. internal-PC START UP PC / FORCE QUIT, HDMI3 82h, HOME 87h, USB-C 89h) apply to every PN-LW H model variant unconfirmed. (5) No PN-LW H-specific protocol additions/removals documented." ``` --- From the AI4AV catalog (https://ai4av.net) · ODbL-1.0
