Sharp/NEC NC603L Control Spec

Summary

The Sharp/NEC NC603L is a projector controllable via RS-232C serial or TCP/IP LAN (port 7142) using a binary hex command protocol. This spec covers the full command catalogue from the Projector Control Command Reference Manual (BDT140013 Rev 7.1): power, input switching, mute, picture/volume/aspect adjust, lens control and memory, shutter, freeze, eco mode, edge blending, PIP/PbP, and a broad set of status/information queries.

Transport

protocols:
  - tcp
  - serial
addressing:
  port: 7142
serial:
  baud_rate: 115200  # source: 115200/38400/19200/9600/4800 bps supported
  data_bits: 8

Traits

# - powerable       (015 POWER ON / 016 POWER OFF present)
# - queryable       (many status/information request commands present)
# - levelable       (030-1 PICTURE ADJUST, 030-2 VOLUME ADJUST, 030-15 LAMP ADJUST)
# - routable        (018 INPUT SW CHANGE present)
traits:
  - powerable
  - queryable
  - levelable
  - routable

Actions

# Notes on protocol framing (from source sec 2.1-2.2):
#  - Commands/responses are binary hex byte sequences.
#  - <ID1> = Control ID set on projector; <ID2> = model code (per-device).
#  - <CKS> = checksum = low-order byte of sum of all preceding bytes.
#  - Command opcodes listed below are the fixed leading bytes (e.g. "02h 00h ...").
#    Parameterized fields shown as {var}; checksum computed over full frame.
#  - All payloads below are verbatim from the source unless marked parameterized.

# UNRESOLVED: valid integer ranges for picture/volume/lamp adjust are device-reported at runtime via 060-1 GAIN PARAMETER REQUEST 3; fixed min/max not stated in this manual.

Events

# No unsolicited notifications documented in source. Device responds only to commands.
# UNRESOLVED: no event/notification section in source.

Macros

# No multi-step sequences described explicitly in source.
# UNRESOLVED: no macros documented.

Safety

confirmation_required_for: []
interlocks: []
notes:
  - "015 POWER ON: while powering on, no other command accepted."
  - "016 POWER OFF: while powering off (incl. cooling time), no other command accepted."
  - "009 ERROR STATUS REQUEST exposes an interlock-switch-open bit (DATA09 Bit1) and system error bits (DATA09 Bit2/Bit3) that indicate fault conditions."
# UNRESOLVED: source contains no explicit safety interlock procedures, power-on sequencing requirements, or confirmation-required operations beyond the command-acceptance notes above.

Notes

• Protocol is binary hex; all commands/responses are byte sequences, not ASCII.
• Framing: first byte is a message-type/opcode prefix (00h/01h/02h/03h = command classes; 20h/21h/22h/23h = successful-response counterparts; A0h-A3h = error-response counterparts). <ID1> = control ID set on projector, <ID2> = model code; both per-device values not fixed in source.
• Checksum <CKS> = low-order byte of the sum of all preceding bytes (see source sec 2.2 example).
• Serial: RS-232C cross cable on PC CONTROL port (D-SUB 9P). LAN: RJ-45, TCP port 7142. Wireless LAN also supported via separate wireless LAN unit (see operation manual).
• Baud rate is selectable among 4800/9600/19200/38400/115200 bps; spec lists 115200 as the default value field but device configuration determines the active rate.
• Many input-terminal, aspect, eco-mode, and sub-input value tables are referenced to an "Appendix: Supplementary Information by Command" not included in this refined source; those enums are marked as Appendix-referenced in the relevant params.
• Error responses use <ERR1> <ERR2> code pairs (see source sec 2.4); e.g. 02h 0Dh = "command cannot be accepted because the power is off".

Known Gaps

- "firmware version compatibility not stated in source. Control ID (ID1) and model code (ID2) are per-device values not fixed in source."
- "flow control not stated in source (source states \"Full duplex\" communication mode only)"
- "valid integer ranges for picture/volume/lamp adjust are device-reported at runtime via 060-1 GAIN PARAMETER REQUEST 3; fixed min/max not stated in this manual."
- "no event/notification section in source."
- "no macros documented."
- "source contains no explicit safety interlock procedures, power-on sequencing requirements, or confirmation-required operations beyond the command-acceptance notes above."
- "firmware version compatibility not stated."
- "control ID (ID1) default and model code (ID2) value not stated."
- "serial flow control not stated (only \"Full duplex\" mode documented)."
- "full enumerated value lists for input terminal, aspect, eco mode, and sub-input are in an Appendix not present in this source."
- "picture/volume/lamp adjust min/max/default ranges — device-reported at runtime via 060-1, not fixed in manual."
