Summary

Control spec for the Sharp/NEC Xp A155U B projector (BDT140013 Rev 7.1 command reference). The device supports both RS-232C serial control and TCP/IP LAN control (port 7142). Commands are binary hex frames; each frame carries a checksum computed as the low-order byte of the sum of all preceding bytes.

Transport

protocols:
  - tcp
  - serial
addressing:
  port: 7142
serial:
  baud_rate: 4800  # source lists supported set: 4800/9600/19200/38400/115200 bps; default UNRESOLVED
  supported_baud_rates: [4800, 9600, 19200, 38400, 115200]
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # UNRESOLVED: source states full-duplex communication mode but no explicit flow-control setting
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable      # inferred: POWER ON (015) / POWER OFF (016) commands present
  - routable       # inferred: INPUT SW CHANGE (018) input switching present
  - queryable      # inferred: many status/information request commands present
  - levelable      # inferred: VOLUME ADJUST (030-2), PICTURE ADJUST (030-1), LENS CONTROL present

Actions

# Command frame: <CMD> ... <CKS>. CKS = low-order byte of sum of all preceding bytes.
# Responses: success uses 2xh/A-prefix bytes; error uses Axh with ERR1/ERR2/CKS.
# <ID1> = control ID; <ID2> = model code (varies by model).

Variables

# Query responses return dynamic values (lamp usage time, filter usage time, gain ranges,
# model name, serial number, MAC address, etc.). These are read via the query Actions above.
# No standalone settable parameter variables beyond those expressed as Actions.

Events

# Source describes only command/response. No unsolicited notification events documented.
# UNRESOLVED: no events present in source

Macros

# No multi-step sequences described explicitly in source.
# UNRESOLVED: no macros present in source

Safety

confirmation_required_for: []
interlocks:
  - "POWER ON (015): while turning on power, no other command can be accepted."
  - "POWER OFF (016): while turning off power (including cooling time), no other command can be accepted."
  - "PICTURE/SOUND/ONSCREEN mute turned off automatically on input terminal switch or video signal switch."
  - "Sound mute turned off on sound volume adjustment."
# UNRESOLVED: no explicit power-on sequencing requirements or safety interlock procedures
# beyond command-acceptance locks stated in source.

Notes

  • Command reference manual revision: BDT140013 Rev 7.1.
  • Serial cable must be a cross cable; connect to PC CONTROL port (D-SUB 9P). Pinout: 2(RxD)/3(TxD)/5(GND)/7(RTS)/8(CTS).
  • LAN wired: 10/100 Mbps auto-switchable (IEEE802.3, IEEE802.3u). Wireless LAN via optional wireless LAN unit (see separate manual).
  • Checksum (CKS): low-order one byte of the sum of all preceding bytes. Example: 20h+81h+01h+60h+01h+00h=103h → CKS=03h.
  • Success response opcode prefix is 2xh (e.g. 22h/23h); error response opcode prefix is Axh (e.g. A2h/A3h) with ERR1/ERR2.
  • = control ID set on projector; = model code (varies by model, not fixed in this source).
  • Lamp usage time and filter usage time update at one-minute intervals though returned in one-second units.
  • Lamp remaining life (%) returns negative if lamp replacement deadline is exceeded.
  • Edge blending SET response in source lists DATA02 return values as 00h/01h (likely mirrors setting 00h/01h).
