Summary

Sharp Aquos LCD monitor supporting dual-control interfaces: RS-232C (9-pin D-Sub, 9600bps ASCII) and LAN (TCP port 7142). Protocol stack uses VCP (Variable Content Protocol) for standard parameters and CTL (Control) commands for special operations. Command packet structure: SOH header + STX message block + BCC check code + CR delimiter. Minimum packet interval: 600ms.

Events

# UNRESOLVED: monitor does not send unsolicited events. NULL message (CTL-C2xx BE) is returned on timeout/error only.

Macros

# UNRESOLVED: no explicit multi-step macros in source. Typical procedure (Section 6) demonstrates:
#   1. Get current value (VCP Get)
#   2. Set new value (VCP Set)
#   3. Confirm (VCP Set reply)
#   4. Save (CTL-0C Save Current Settings)
# This 4-step pattern is a de facto macro.

Safety

confirmation_required_for: []
interlocks:
  - "Power ON/OFF, Auto Setup, Input, PIP Input, Auto Setup, and Factory reset require time to execute - monitor returns NULL message if another command arrives during execution."
  - "Monitor disconnects TCP connection after 15 minutes of no packet data. Controller must re-connect."
  - "Packet interval must be longer than 600ms for both RS-232C and LAN."
# UNRESOLVED: no explicit safety interlocks for power sequencing, voltage, or current stated in source.

Notes

Command encoding: All byte data encoded as ASCII character pairs. Example: 02h → '0'(30h) + '2'(32h). All commands end with CR (0Dh) delimiter.

BCC calculation: Block Check Code = D1 xor D2 xor ... xor D16 (xor from Reserved byte through ETX). Example: 30h xor 41h xor 30h xor 45h xor 30h xor 41h xor 02h xor 30h xor 30h xor 31h xor 30h xor 30h xor 30h xor 36h xor 34h xor 03h = 77h.

Monitor ID addressing: Single monitor: ID 1→'A'(41h), ID 2→'B'(42h), ..., ID 100→'A4h'. Broadcast: '＊'(2Ah). Group addressing: '1'(31h) through '9'(39h) for groups A-I.

VCP vs CTL: VCP (Variable Content Protocol) covers standard parameters (backlight, contrast, input, etc.) via page+code. CTL (Control) covers special operations (power, serial number, firmware, remote codes, etc.).

NULL message (CTL-C2xx BE): Returned on timeout (default 10s), unsupported message, BCC error, or when monitor is busy executing a long operation (Power ON/OFF, Auto Setup, Input, PIP, Factory reset).

Verification Summary

verdict: verified
checked_at: 2026-06-10T00:44:56.677Z
matched_actions: 81
action_count: 81
confidence: medium
summary: "All 81 spec actions match documented CTL/VCP wire tokens verbatim; transport baud 9600 and TCP port 7142 confirmed; source S=84 at spec granularity yields 81/84=0.96 coverage ratio above 0.9 threshold, remaining 3 source commands (CTL-CA04-03, VCP-10-3E, VCP-02-3E) represented in spec Variables section. (6 unresolved item(s) noted in Known Gaps.)"

Known Gaps

- "exact model variants (LC-60E77UM vs LC-52E77U) share the same protocol; family-wide applicability confirmed by shared doc title. UNRESOLVED: TV tuner commands (*1 models) not verified for all variants."
- "flow control not stated in source"
- "monitor does not send unsolicited events. NULL message (CTL-C2xx BE) is returned on timeout/error only."
- "no explicit multi-step macros in source. Typical procedure (Section 6) demonstrates:"
- "no explicit safety interlocks for power sequencing, voltage, or current stated in source."
- "IP address assignment method (DHCP vs static) not documented beyond \"DHCP:On\". UNRESOLVED: flow control (RTS/CTS or XON/XOFF) not stated. UNRESOLVED: TV tuner models (*1) channel commands not verified for all E77UM variants. UNRESOLVED: video input resolution via VCP-02-50/51 readout values not fully specified."
