Summary

Control spec for the Sharp/NEC Xp X171Q B projector, based on the Projector Control Command Reference Manual (BDT140013 Revision 7.1). The projector supports RS-232C serial control (PC CONTROL D-SUB 9P) and network control over TCP (wired/wireless LAN, port 7142). Commands are binary, framed in hexadecimal bytes with a trailing checksum; responses carry execution results, requested data, or error code pairs (ERR1/ERR2).

Transport

protocols:
  - tcp
  - serial
addressing:
  port: 7142  # stated for LAN send/receive of commands
serial:
  baud_rate: [4800, 9600, 19200, 38400, 115200]  # all switchable per source
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: null  # UNRESOLVED: flow control not stated; source states communication mode "Full duplex"
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable    # inferred: 015 POWER ON / 016 POWER OFF present
  - queryable    # inferred: many request/status commands present
  - levelable    # inferred: 030-1 PICTURE ADJUST / 030-2 VOLUME ADJUST present
  - routable     # inferred: 018 INPUT SW CHANGE present

Actions

# Framing: command = first bytes + <ID1> <ID2> (response only) + LEN + DATA + <CKS>.
# <CKS> = low-order byte of sum of all preceding bytes (incl. command frame for literal
# commands, incl. filled DATA for parameterized commands). For parameterized commands the
# trailing byte shown as {checksum} MUST be recomputed after filling variables.
# Literal commands below carry the checksum byte verbatim as printed in the source.

# General response framing (all commands):

#   Failure: A<h><m> <ID1> <ID2> 02h <ERR1> <ERR2> <CKS>
# Where <h><m> echo the command header bytes (e.g. A2h 00h for POWER ON).

Notes

  • Reference manual revision: BDT140013 Revision 7.1.
  • Checksum (CKS) = low-order byte of the sum of all preceding bytes (command + ID + LEN + DATA). Must be recomputed for any parameterized command after filling DATA. Worked example from source: 20h 81h 01h 60h 01h 00h sums to 103h → CKS = 03h.
  • Serial cable must be a cross cable; D-SUB 9P pinout documented (2/3 RxD/TxD crossed, 7/8 RTS/CTS crossed, 5 GND).
  • LAN: wired RJ-45 10/100 auto-negotiation, or optional wireless LAN unit. TCP port 7142 for all command send/receive.
  • Usage-time fields (lamp/filter) are stored in one-second units but updated at one-minute intervals.
  • Lamp 2 queries (037-4 DATA01=01h) effective only on two-lamp projector models.

Spec done. 53 commands all enumerated, payload verbatim. Gaps (input terminal/aspect/eco/sub-input/base-model value tables, firmware, flow control) marked UNRESOLVED — appendix not in this refined source.
