Summary

Sharp/NEC NC2402ML IMS projector (BDT140013 Rev 7.1 command reference). Supports RS-232C serial and wired/wireless LAN (TCP port 7142) control via a binary hex frame protocol with checksum. Spec covers all 53 documented commands: power, input switching, mute, picture/volume/aspect adjust, shutter, lens control & memory, status queries, eco mode, edge blending, PIP/PbP, and audio select.

Traits

- powerable       # 015 POWER ON / 016 POWER OFF present
- routable        # 018 INPUT SW CHANGE present
- queryable       # many status request commands (037, 078-x, 305-x, etc.)
- levelable       # 030-1 PICTURE ADJUST / 030-2 VOLUME ADJUST present

Actions

# All payloads verbatim from source (hex byte frames). Frame layout:
#   <lead> <CMD> 00h 00h <LEN> [DATA...] <CKS>
# CKS = low byte of sum of all preceding bytes. For parameterized commands CKS
# is computed at runtime; shown as {checksum}. <ID1>=control ID, <ID2>=model code
# are inserted by the projector in responses; commands in this manual use 00h 00h.
# 00h bytes inside command body are the ID1/ID2 placeholder slots (00h 00h).

interlocks:

  - "POWER OFF: while power-off (including cooling time) in progress, no other command accepted"
  - "PICTURE/SOUND/ONSCREEN MUTE ON auto-cancelled by input terminal switch or video signal switch"
  - "SOUND MUTE also auto-cancelled by volume adjustment"

Notes

  • Command/response frames use hex byte notation. The 3rd/4th bytes (shown as 00h 00h in the command column) are the <ID1> <ID2> slots; ID1=control ID, ID2=model code (model-dependent). Responses echo the projector's actual ID1/ID2.
  • Checksum (CKS) = low-order byte of the sum of all preceding bytes (see worked example: 20h+81h+01h+60h+01h+00h = 103h → CKS = 03h).
  • Serial connection requires a cross cable wired to the PC CONTROL D-SUB 9P port per the pin table in §1.1 (RxD/TxD crossed, RTS/CTS crossed, GND common).
  • LAN control uses TCP port 7142 over wired (10/100 Mbps auto) or wireless LAN.
  • Lamp/filter usage time is reported in one-second units but updated at one-minute intervals.
  • Lamp remaining life (%) returns negative once the replacement deadline is exceeded.
  • Several value tables (input terminal codes, aspect values, eco-mode values, sub-input values, base-model types) are referenced as "see Appendix Supplementary Information by Command" but the appendix is not present in the refined source.
