Sharp/NEC NC2041L IMS Control Spec

Summary

Binary hex control protocol for Sharp/NEC projectors (source: "Projector Control Command Reference Manual" BDT140013 Rev 7.1), applicable to the NC2041L. Supports RS-232C serial (PC CONTROL port) and wired/wireless LAN (TCP port 7142). Covers power, input switching, mutes, picture/volume adjust, lens control/memory, status and information queries.

Transport

protocols:
  - serial
  - tcp
addressing:
  port: 7142
serial:
  baud_rate: 115200/38400/19200/9600/4800  # supported set as stated in source
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: null  # UNRESOLVED: RTS/CTS pins wired per pinout but flow control setting not stated in source
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable    # inferred from POWER ON/OFF commands (015/016)
  - routable     # inferred from INPUT SW CHANGE command (018)
  - queryable    # inferred from extensive request commands (009, 037 series, 078 series, etc.)
  - levelable    # inferred from PICTURE ADJUST / VOLUME ADJUST commands (030-1, 030-2)

Actions

# Frame format: <cmd bytes> <ID1> <ID2> <LEN> <DATA..> <CKS> (responses); commands carry fixed payload.
# CKS = low-order byte of sum of all preceding bytes.

Variables

# Settable parameters (volume, picture levels, eco mode, edge blending, PIP/PbP, lens memory
# options, projector name) are represented as parameterized Actions per source command structure.
# No additional variables beyond those actions. <!-- UNRESOLVED: numeric adjustment ranges for
# picture/volume/lamp adjust not stated in source (query 060-1 returns ranges from device) -->

Events

# Source documents no unsolicited notifications; all responses are solicited command replies.

Macros

# Source documents no multi-step sequences.

Safety

confirmation_required_for: []
interlocks: []
# Source states no explicit interlock procedures. Error status bitmap (009) reports
# "interlock switch is open" (DATA09 bit1) as an observable error condition only.

Notes

• Checksum: CKS = low-order one byte of the sum of all preceding bytes. Example: 20h+81h+01h+60h+01h+00h=103h → CKS=03h.
• Command frame: fixed 6-byte prefix for most commands; responses echo ID1 (control ID set on projector), ID2 (model code, varies by model), LEN, data, CKS. Error responses: Ah 02h .
• POWER ON (015) and POWER OFF (016) accept no other command while power transition (including cooling) is in progress.
• Picture/onscreen mute auto-cancel on input terminal switch or video signal switch; sound mute also cancels on volume adjustment.
• Some models cannot receive LAN commands in standby mode ("Standby Mode setting for receiving commands" — model-specific, not detailed in source).
• Signal list number returned by 078-3 is actual value minus 1; add 1 for practical number.
• Lamp/filter usage times obtainable in 1-second units but updated at 1-minute intervals.

Known Gaps

- "source is a generic multi-model command reference; model-specific support (input terminal values, aspect values, eco mode values, base model types, key code availability) is deferred to an Appendix (\"Supplementary Information by Command\") not included in the source text"
- "ID2 model code values not stated in source"
- "standby command reception capability for this model not stated in source"
- "RTS/CTS pins wired per pinout but flow control setting not stated in source"
- "eco mode values deferred to Appendix, not in source"
- "numeric adjustment ranges for"
- "input terminal value table, aspect value table, eco mode value table, base model type table, sub-input value table not in source (deferred to Appendix)"
- "default/serial baud rate selection mechanism not stated"
- "053-1 lens axis selector values not enumerated in source"
