Summary

Sharp/NEC Xp A201U B projector control spec. Supports RS-232C serial and wired/wireless LAN (TCP) control via binary command protocol. Source covers power, input switch, mutes, picture/volume/aspect adjust, lens/shutter, freeze, eco mode, edge blending, PiP/PbP, and numerous status-request queries.

Events

# UNRESOLVED: source documents no unsolicited notifications. Projector returns responses only after commands.

Macros

# UNRESOLVED: source documents no multi-step macro sequences.

Safety

confirmation_required_for: []
interlocks:
  - command: power_on
    notes: "No other command accepted while power-on in progress."
  - command: power_off
    notes: "No other command accepted during power-off (including cooling time)."
  - command: lens_control
    notes: "Send 00h (stop) after 7Fh/81h continuous drive to halt lens."
# UNRESOLVED: no voltage/current/power specs in source. No explicit power-on sequencing interlock beyond single-command lockout noted above.

Notes

  • Command format: {20h..3Fh} {opcode} {ID1} {ID2} {LEN} {DATA...} {CKS}. First byte encodes direction/type (02h/03h = set command, 22h/23h = success ack, A2h/A3h = error ack, 20h = get response).
  • ID1 = control ID set on projector (runtime, not fixed). ID2 = model code (varies by model, UNRESOLVED for this model).
  • Checksum (CKS): sum of all preceding bytes, low-order 8 bits.
  • Serial baud rate configurable: 115200/38400/19200/9600/4800 bps. Source does not state default; 115200 used as placeholder above (UNRESOLVED: which is factory default).
  • TCP port 7142 stated for LAN command send/receive.
  • Response errors carried in ERR1/ERR2 (see §2.4 error code list, 24 entries documented in source).
  • Lamp/filter usage time returned in seconds, updated at 1-minute intervals.
