Sharp Electronics XP-A824U-W Control Spec

Summary

Installation-class DLP projector supporting HDMI1, HDMI2 and HDBaseT inputs. This spec covers the RS-232 PC Control port (D-Sub 9P), LAN/HDBaseT TCP control (port 7142), HTTP server, PJLink, CRESTRON ROOMVIEW, AMX Device Discovery, Extron XTP, and Art-Net DMX-over-Ethernet lighting control. Both binary (Command Format A) and ASCII (Command Format B) PC control code tables are documented in the source.

Transport

# Source documents RS-232 (PC CONTROL D-Sub 9P), LAN/HDBaseT TCP (port 7142),

Feedbacks

# ASCII input command responses (source: "Parameters for this device" table).
- id: input_response
  type: enum
  values: [hdmi1, hdmi2, hdbaset]
# ASCII status / error responses (source: "Status command" table).
- id: error_status
  type: enum
  values:
    - error:temp
    - error:fan
    - error:light
    - error:lens
    - error:system

Variables

# Settable parameters documented via menu (mirrored as ASCII control where applicable).
# Source explicitly enumerates "Communication speed" 4800/9600/19200/38400/115200 bps
# on the PC CONTROL port.
- name: communication_speed
  type: enum
  values: [4800, 9600, 19200, 38400, 115200]
  description: RS-232 baud rate, selectable via SETUP -> CONTROL(1) -> COMMUNICATION SPEED (default 38400 bps per menu table).

Events

# Source documents status responses only (replies to query commands). No unsolicited
# notification scheme documented.
# UNRESOLVED: populate if source describes push/asynchronous state change messages.

Macros

# Synchronous Control (per source) coordinates power on/off, AV mute, shutter, signal mute,
# dynamic contrast and auto black shutter across 2-4 projectors on LAN. Multi-step sequence
# documented at SETUP -> CONTROL(2) -> SYNCHRONOUS CONTROL.
- id: synchronous_control_setup
  label: Synchronous Control setup (MAIN projector)
  steps:
    - SETUP -> CONTROL(2) -> SYNCHRONOUS CONTROL -> MODE = MAIN
    - SETUP -> CONTROL(2) -> SYNCHRONOUS CONTROL -> UNITS = 2|3|4
    - Set SUB1, SUB2, SUB3 IP addresses
    - Confirm with OK; sub-projectors receive MODE, MAIN IP, SIGNAL MUTE

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: source contains no explicit safety warnings, interlock procedures, or
# power-on sequencing requirements related to the control interface. Mentions to
# "heat protection functions" and a "Thermometer symbol" exist in menu docs but are
# not protocol-level safety statements.

Notes

• Two command formats selectable via SETUP → CONTROL(1) → COMMAND FORMAT (A or B). Source notes "(SP) = 20H ASCII, (CR) = 0DH ASCII" for Format B.
• Source directs operator to "https://www.sharp-nec-displays.com/dl/en/pj_manual/lineup.html" for the full ASCII command list — the provided excerpt is partial.
• TCP control available via LAN (auto 10/100 Mbps) and via HDBaseT (100 Mbps), both using TCP port 7142.
• HTTP server can be set to OFF / ON / AUTH. (menu SETUP → NETWORK → NETWORK SERVICE → HTTP SERVER).
• PJLink (CLASS1 / CLASS2), CRESTRON ROOMVIEW, CRESTRON CONTROL (ENABLE / CONTROLLER IP / IP ID), AMX Device Discovery, Extron XTP, Art-Net, and PC CONTROL (with AUTH.) are independently toggleable.
• Art-Net DMX channels documented in source table (POWER, INPUT, BLANK, SHUTTER, FREEZE, LIGHT ADJUST, LENS SHIFT H/V, FOCUS, ZOOM, KEYSTONE H/V, LOCK). Default universe / subnet not stated.
• PC CONTROL connector pinout: pin 2 RxD, pin 3 TxD, pin 5 GND, pin 7 RTS, pin 8 CTS; pins 1/4/6/9 unused.

action_count: 18
confidence: medium
summary: "All 18 spec actions (9 binary Format A + 9 ASCII Format B) appear verbatim in source tables; transport (TCP 7142, baud rates) verified. (4 unresolved item(s) noted in Known Gaps.)"

Known Gaps

- "complete command list (source says \"Contact your local dealer for a full list of the PC Control Codes\"); lens/menu feedback responses; Art-Net default universe/subnet not stated"
- "populate if source describes push/asynchronous state change messages."
- "source contains no explicit safety warnings, interlock procedures, or"
- "framing bytes for Command Format A (header/trailer/checksum) not documented in excerpt; default Art-Net universe/subnet not stated; full ASCII command list behind vendor URL; feedback responses beyond input + error tables not present in excerpt"
