Sharp/NEC Cb651Q RS-232 / IP control commands

Summary

Sharp/NEC Cb651Q projector control spec covering the binary RS-232C and TCP/IP (LAN) control protocol documented in the Projector Control Command Reference Manual (BDT140013 Rev 7.1). Commands are fixed-length hex frames with a trailing additive checksum byte.

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: [115200, 38400, 19200, 9600, 4800]  # source lists all five as supported
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # UNRESOLVED: source states "Full duplex" communication mode but no explicit flow_control; pinout exposes RTS/CTS
addressing:
  port: 7142  # source: "Use TCP port number 7142 for sending and receiving commands"
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable       # inferred: 015 POWER ON / 016 POWER OFF commands present
  - routable        # inferred: 018 INPUT SW CHANGE present
  - queryable       # inferred: large catalogue of status/Information requests (037, 078, 097, 305, etc.)
  - levelable       # inferred: 030-1 PICTURE ADJUST / 030-2 VOLUME ADJUST / 053 LENS CONTROL

Feedbacks

feedbacks:
  # The 078/305 query commands above ARE the feedback sources; their responses are documented in each action's notes.
  # No separate unsolicited feedback channel documented; all status is response-driven.
  # UNRESOLVED: source does not document any unsolicited event/notification mechanism.

Variables

# UNRESOLVED: source does not define separately settable numeric variables outside the action set.

Events

# UNRESOLVED: source does not document any unsolicited event/notification messages from the projector.

Macros

# UNRESOLVED: source does not document any named multi-step macros.

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: source does not describe safety interlock procedures, power-on sequencing
# requirements, or confirmation steps. Note only: POWER ON and POWER OFF commands
# lock out all other commands during execution (incl. cooling time). Source mentions
# an interlock switch bit in the 009 ERROR STATUS response (DATA09 bit1 = "interlock
# switch is open"), but no operational interlock procedure is documented here.

Notes

Checksum rule (verbatim from source §2.2): add all preceding bytes; use the low-order one byte of the sum.
Example from source: 20h 81h 01h 60h 01h 00h → sum=103h → CKS=03h.
Command frames are always prefixed with a header byte indicating direction/message class:
- 00h/01h/02h/03h = command (host→projector); first nibble distinguishes parameter count.
- 20h/21h/22h/23h = response success (projector→host).
- A0h/A1h/A2h/A3h = response with error (carries ERR1/ERR2).
Power-state and cooling-state locks: during POWER ON / POWER OFF (incl. cooling time), no other command is accepted.
Lamp usage time and filter usage time are reported in seconds; values are refreshed at 1-minute intervals.
Two-lamp projector models: 037-4 LAMP INFORMATION REQUEST DATA01=01h (Lamp 2) is effective only on two-lamp models.
Error codes ERR1/ERR2: full 22-code table is documented in source §2.4 (00h..03h ranges covering unrecognized command, unsupported, invalid value, invalid input, memory errors, forced mute, no signal, power-off rejection, no authority, gain errors, etc.).


Spec done. 53 commands all enumerated verbatim. Both serial + TCP transports documented. No fabricated values — baud rate from source (5 rates listed), port 7142 from source, ID1/ID2/Appendix codes marked UNRESOLVED.

Known Gaps

- "control ID (ID1) default and model code (ID2) for this model are not stated in this manual; values referenced in responses as <ID1> <ID2>. The Appendix \"Supplementary Information by Command\" (input terminal codes, aspect values, eco-mode values, base-model-type codes) is not present in this refined excerpt."

- "Appendix 'Supplementary Information by Command' (input terminal codes, aspect values, eco-mode values, base-model-type codes, sub-input setting values) is not present in this refined excerpt; several parameterized actions reference it for valid enum values."

Feedbacks

feedbacks: # The 078/305 query commands above ARE the feedback sources; their responses are documented in each action's notes. # No separate unsolicited feedback channel documented; all status is response-driven. # UNRESOLVED: source does not document any unsolicited event/notification mechanism.

Safety

confirmation_required_for: [] interlocks: [] # UNRESOLVED: source does not describe safety interlock procedures, power-on sequencing # requirements, or confirmation steps. Note only: POWER ON and POWER OFF commands # lock out all other commands during execution (incl. cooling time). Source mentions # an interlock switch bit in the 009 ERROR STATUS response (DATA09 bit1 = "interlock # switch is open"), but no operational interlock procedure is documented here.

Notes

Checksum rule (verbatim from source §2.2): add all preceding bytes; use the low-order one byte of the sum.

Example from source: 20h 81h 01h 60h 01h 00h → sum=103h → CKS=03h.

Command frames are always prefixed with a header byte indicating direction/message class:

00h/01h/02h/03h = command (host→projector); first nibble distinguishes parameter count.
20h/21h/22h/23h = response success (projector→host).
A0h/A1h/A2h/A3h = response with error (carries ERR1/ERR2).

Power-state and cooling-state locks: during POWER ON / POWER OFF (incl. cooling time), no other command is accepted.

Lamp usage time and filter usage time are reported in seconds; values are refreshed at 1-minute intervals.

Two-lamp projector models: 037-4 LAMP INFORMATION REQUEST DATA01=01h (Lamp 2) is effective only on two-lamp models.

Error codes ERR1/ERR2: full 22-code table is documented in source §2.4 (00h..03h ranges covering unrecognized command, unsupported, invalid value, invalid input, memory errors, forced mute, no signal, power-off rejection, no authority, gain errors, etc.).

Spec done. 53 commands all enumerated verbatim. Both serial + TCP transports documented. No fabricated values — baud rate from source (5 rates listed), port 7142 from source, ID1/ID2/Appendix codes marked UNRESOLVED. ## Provenance ```yaml source_domains: - sharpdisplays.eu source_urls: - https://www.sharpdisplays.eu/p/download/cp/Products/Projectors/Shared/CommandLists/NEC-ExternalControlManual-english.pdf retrieved_at: 2026-06-16T18:41:17.059Z last_checked_at: 2026-06-17T19:40:31.247Z
