Sharp/NEC PA243W BK Control Spec

Summary

Sharp/NEC projector controlled via RS-232C serial or wired/wireless LAN (TCP port 7142). Binary command protocol using hex-byte frames with checksum. Covers power, input switching, mute (picture/sound/onscreen), picture/volume/aspect/gain adjustment, lens control and memory, shutter, freeze, eco mode, PIP/PbP, edge blending, and extensive status queries including error status, lamp/filter usage, model info, and MAC address. Source document: Projector Control Command Reference Manual (BDT140013 Revision 7.1).

Transport

protocols:
  - tcp
  - serial
addressing:
  port: 7142
serial:
  baud_rate: [4800, 9600, 19200, 38400, 115200]  # all supported per source; default not stated
  data_bits: 8
  parity: none
  stop_bits: 1
  # UNRESOLVED: flow_control not stated in source (RTS/CTS pins present on D-SUB 9P but no setting documented)
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable  # inferred from POWER ON (015) / POWER OFF (016) commands
  - queryable  # inferred from extensive status query commands (009, 037, 078, 305, etc.)
  - levelable  # inferred from PICTURE ADJUST, VOLUME ADJUST, OTHER ADJUST commands

Actions

# Binary protocol: commands are hex-byte frames. Format:
#   [type] [code] 00h 00h [LEN] [DATA...] [CKS]
# Response (success):  [type+20h] [code] <ID1> <ID2> [LEN] [DATA...] <CKS>
# Response (error):    [type+80h] [code] <ID1> <ID2> 02h <ERR1> <ERR2> <CKS>
# CKS = low-order byte of sum of all preceding bytes.
# ID1 = control ID set on projector; ID2 = model code (varies by model).
# All command payloads are verbatim from the source document.

Notes

• Binary protocol with hex-byte framing. Command frame: [type] [code] 00h 00h [LEN] [DATA...] [CKS]. Success response prepends type+20h and includes <ID1> <ID2>. Error response prepends type+80h with 02h <ERR1> <ERR2>.
• Checksum (CKS): sum all preceding bytes, take low-order byte (8 bits).
• ID1 = control ID set on projector. ID2 = model code, varies by model. Neither value is documented in this source.
• Serial cable: D-SUB 9P cross cable. Pin assignment: 2=RxD, 3=TxD, 5=GND, 7=RTS, 8=CTS.
• LAN: RJ-45 connector, 10/100 Mbps auto-switchable (IEEE 802.3 / 802.3u). TCP port 7142.
• Wireless LAN: requires separate wireless LAN unit (see operation manual).
• Several commands reference an "Appendix: Supplementary Information by Command" for input terminal values, aspect values, eco mode values, base model type values, and sub input setting values. This appendix is not included in the source text.
• Information query data (lamp/filter usage) is updated at 1-minute intervals despite being available in 1-second units.
