Summary

Sharp/NEC NC1202L is a projector controllable via an RS-232C serial port (PC CONTROL, D-SUB 9P) or a wired/wireless LAN connection using TCP port 7142. Commands are binary frames using a fixed header, model/control IDs, a length byte, a data payload, and a single-byte additive checksum (low-order 8 bits of the sum of all preceding bytes).

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: null  # source lists supported rates 115200/38400/19200/9600/4800 bps; no single default stated
  supported_baud_rates: [115200, 38400, 19200, 9600, 4800]
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # full-duplex communication stated; hardware flow pins (RTS/CTS) wired in the cable pinout
addressing:
  port: 7142
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable    # inferred: POWER ON / POWER OFF commands present
  - queryable    # inferred: many status/information request commands present
  - routable     # inferred: INPUT SW CHANGE / AUDIO SELECT SET present
  - levelable    # inferred: PICTURE/VOLUME/LAMP ADJUST commands present

Actions

# All frames use the source's general command/response structure:
#   <HDR> <MT> 00h 00h <LEN> <DATA...> <CKS>
# HDR/MT identify the command; LEN is the data length following LEN; CKS is the
# low-order 8 bits of the sum of all preceding bytes.
# <ID1> = control ID set on projector; <ID2> = model code. Neither value is
# stated for the NC1202L in the source - see UNRESOLVED markers above.

Variables

# Settable parameters are represented as Actions above (PICTURE ADJUST,
# VOLUME ADJUST, ASPECT ADJUST, OTHER ADJUST, ECO MODE SET, LENS CONTROL,
# FREEZE CONTROL, etc.). No additional standalone variables documented.

Events

# Source describes no unsolicited notifications. All output is in response to a command.
# UNRESOLVED: no async event/notification mechanism documented.

Macros

# Source documents no explicit multi-step command sequences.
# UNRESOLVED: no macros described.

Safety

confirmation_required_for: []
interlocks:
  - "While POWER ON command is executing, no other command can be accepted."
  - "While POWER OFF is executing (incl. cooling time), no other command can be accepted."
# UNRESOLVED: source contains no explicit safety interlock procedures, voltage/current
# specs, or power-on sequencing requirements beyond the command-blocking notes above.

Notes

  • Command/response framing is binary hex. General request structure: <HDR> <MT> 00h 00h <LEN> <DATA...> <CKS> where HDR selects class (00h/01h/02h/03h) and MT is the message-type byte. General response structure: <RESP_HDR> <MT> <ID1> <ID2> <LEN> <DATA...> <CKS> (RESP_HDR = 20h-23h success, A0h-A3h error).
  • Checksum (CKS) = low-order 8 bits of the sum of all preceding bytes. Worked example from source: 20h + 81h + 01h + 60h + 01h + 00h = 103h => CKS = 03h.
  • <ID1> is the projector's configured control ID; <ID2> is the model code (varies by model). Neither is stated for the NC1202L in this source — must be obtained from the device.
  • Serial cable is a cross cable; RTS/CTS pins are cross-wired between PC CONTROL (D-SUB 9P) and the external device.
  • Many enum values (input terminals, aspect values, eco-mode values, base model types, sub-input values) are deferred to an "Appendix: Supplementary Information by Command" that is not present in the refined source excerpt.

Spec ready. 53 actions, all hex payloads verbatim. Both `serial` + `tcp` (port 7142). Many `<!-- UNRESOLVED -->` gaps (ID1/ID2, baud default, appendix enums, firmware).

Known Gaps

- "firmware version compatibility not stated in source"
- "model code (ID2) value for the NC1202L not stated in source; ID2 varies by model"
- "control ID (ID1) default not stated in source"
- "no async event/notification mechanism documented."
- "no macros described."
- "source contains no explicit safety interlock procedures, voltage/current"
- "control ID (ID1) default value not stated in source"
- "model code (ID2) for the NC1202L not stated in source"
- "default/fixed serial baud rate not stated (source lists 5 selectable rates; no single default)"
- "flow_control setting not explicitly stated (full-duplex stated; RTS/CTS cross-wired in cable pinout but software flow control not described)"
- "input terminal / aspect / eco-mode / base-model-type enum tables live in an Appendix not included in the source excerpt"
