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:

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.

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 00hsums 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.
