Sharp Electronics XP-A175U Projector Control Spec

Summary

Sharp XP-A175U projector controlled via binary hex command protocol over RS-232C serial (PC CONTROL D-SUB 9P) or wired LAN (TCP). Commands are framed byte sequences with a control ID, model code, length, data payload, and additive low-byte checksum. Covers power, input switching, mutes, picture/volume/aspect/light adjustment, lens control & memory, shutter, freeze, status queries, and LAN/PIP/edge-blend configuration.

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: null  # UNRESOLVED: source states multiple supported (4800/9600/19200/38400/115200 bps); no default specified
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: null  # UNRESOLVED: flow control not stated; "Full duplex" communication mode stated
addressing:
  port: 7142
auth:
  type: UNRESOLVED  # source does not describe any authentication procedure; type is unsupported

Traits

traits:
  - powerable    # inferred from 015 POWER ON / 016 POWER OFF commands
  - routable     # inferred from 018 INPUT SW CHANGE command
  - queryable    # inferred from extensive *REQUEST commands returning state
  - levelable    # inferred from 030-1 PICTURE ADJUST, 030-2 VOLUME ADJUST, 030-15 LIGHT ADJUST

Actions

# All command payloads are hex byte sequences verbatim from source.
# Framing: bytes use <ID1>=control ID, <ID2>=model code, <CKS>=checksum.
# Checksum (CKS) = low-order 8 bits of sum of all preceding bytes (incl. header & data).
# While power-on/off or cooling is in progress, no other command is accepted (see Safety).

# UNRESOLVED: no explicit safety warnings, power-on sequencing procedures, or
# confirmation-required operations beyond the command-acceptance lockout above.

Notes

• Command/response framing: every frame is a hex byte sequence. Header byte indicates direction/type (00h-03h = host command groups; 20h-23h = success response; A0h-A3h = error response). Each command group prefixes a distinct command category.
• Parameters <ID1> (control ID set on projector), <ID2> (model code), <LEN> (data length in bytes following LEN), and <CKS> (checksum) are common to all commands. Checksum = low-order 8 bits of the sum of all preceding bytes.
• Example checksum from source: 20h+81h+01h+60h+01h+00h = 103h → CKS=03h.
• Mute states (picture/sound/onscreen) auto-clear on input terminal switch, video signal switch, or (sound mute only) volume adjustment.
• Lens drive: after sending continuous-drive (7Fh/81h) in 053 LENS CONTROL, send 00h to stop. While lens is being driven, the same command may be reissued to update position without an intermediate stop.
• Error codes (ERR1/ERR2): 00h/00h=unrecognized command; 01h/00h=invalid value; 01h/01h=invalid input terminal; 02h/03h=value cannot be set; 02h/0Dh=power off; 02h/0Eh=execution failed; 03h/00h=wrong gain number; 03h/02h=adjustment failed (see source §2.4 for full list).
• Standby-mode command reception: XP-A175U receives POWER ON over both serial and wired LAN with Standby Mode set to OFF or ON (appendix A.2).
• Signal list number returned by INPUT STATUS is 1 less than the practical value; add 1 to recover.
• Transport authentication: source does not describe an authentication procedure; transport.auth.type is UNRESOLVED.

Verification Summary

verdict: verified
checked_at: 2026-10-01T08:05:20.064Z
matched_actions: 50
action_count: 50
confidence: medium
summary: "All 50 spec actions match the source's 50 documented command hex bytes one-to-one; transport values are honest (UNRESOLVED where source omits). (10 unresolved item(s) noted in Known Gaps.)"

Known Gaps

- "default baud rate not specified (source lists five supported rates). ID2 model code value for XP-A175U not given numerically. Appendix \"Supplementary Information by Command\" referenced for some enums but not all values present in this excerpt."
- "source states multiple supported (4800/9600/19200/38400/115200 bps); no default specified"
- "flow control not stated; \"Full duplex\" communication mode stated"
- "no explicit safety warnings, power-on sequencing procedures, or"
- "default baud rate among the five supported not specified."
- "flow_control not stated (only \"Full duplex\" comm mode)."
- "ID2 model code numeric for XP-A175U not stated in this excerpt (base-model table gives type bytes FFh/47H/00H/10H but not the wire ID2 value)."
- "firmware version compatibility not stated."
- "voltage/current/power specs not in this command-reference excerpt."
- "response timeouts / inter-command spacing not stated."
