Summary

Sharp/NEC Xp A175U W LCD projector. Control via RS-232C serial (D-SUB 9P PC CONTROL) and TCP/IP LAN (wired RJ-45 or optional wireless LAN unit). Binary hex protocol with frame checksum. Covers full command catalogue from "Projector Control Command Reference Manual" (BDT140013 Rev 7.1): power, input switch, mutes, picture/volume/aspect/gain adjust, lens control + memory, status/error/information queries, eco/edge-blend/PIP/PbP, remote key code, audio select.

Transport

protocols:
  - tcp
  - serial
addressing:
  port: 7142  # source: "Use TCP port number 7142 for sending and receiving commands"
serial:
  baud_rate: 115200  # source lists selectable rates 115200/38400/19200/9600/4800 bps; no single default stated
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # inferred: source does not state flow control mode (RTS/CTS pins are wired)
auth:
  type: none  # inferred: no auth procedure in source

Traits

- powerable    # inferred: 015 POWER ON / 016 POWER OFF commands
- levelable    # inferred: 030-1 PICTURE ADJUST, 030-2 VOLUME ADJUST, 030-15 OTHER ADJUST
- queryable    # inferred: extensive status/information request commands

Actions

# Binary protocol. Command frames verbatim from source. Parameters:
#   ID1 = control ID set on projector; ID2 = model code (varies by model);
#   CKS = checksum = low-order byte of sum of all preceding bytes.
# Response ack frames begin 2xh; error response frames begin Axh (carry ERR1/ERR2).

Variables

# All adjustments are issued as discrete command actions (030-1/030-2/030-12/030-15, lens cmds),
# not via a separate variable namespace. Current values are readable via 060-1 GAIN PARAMETER REQUEST 3.
# No additional settable variable namespace documented.

Events

# None documented. All responses are solicited (reply to a command). No unsolicited push notifications described.

Macros

# No multi-step sequences explicitly described in source.

Safety

confirmation_required_for:
  - power_off  # source: during power-off (incl. cooling time) no other command accepted
  - power_on   # source: during power-on no other command accepted
interlocks:
  - "DATA09 bit1 of ERROR STATUS REQUEST (009): interlock switch open → reported as error"
  - "Cover error, fan error, temperature error (bi-metallic + sensor), mirror cover error, lens-not-installed reported via error status bits"
power_sequencing:
  - "POWER ON (015) and POWER OFF (016) block all other commands for the duration of the power transition / cooling period"
notes: "Error conditions surfaced only by polling 009 ERROR STATUS REQUEST; no unsolicited fault event."

Notes

  • Protocol is binary hex frames over RS-232C (D-SUB 9P, cross cable) or TCP port 7142. Full-duplex serial.
  • Checksum = low-order byte of the sum of all preceding bytes (incl. the leading opcode byte). Example: 20h+81h+01h+60h+01h+00h = 103h → CKS = 03h.
  • Command frames shown are the literal host→projector bytes. Ack frames begin 2xh; error frames begin Axh and carry ERR1/ERR2.
  • ID1 = projector control ID (configurable on device); ID2 = model code (varies per model). Neither is given for Xp A175U W in source — must be read from the device (e.g. via 078-5 / 305-1 / 305-2).
  • Lamp/filter usage times update at 1-minute intervals though returned in 1-second units.
  • Error code pairs (ERR1/ERR2) catalogued in source §2.4 (e.g. 00h/00h unrecognized command; 02h/0Dh power off; 02h/0Fh no authority; 03h/02h adjustment failed).
