Sharp/NEC NP-UM351W Control Spec

Summary

Short-throw LCD projector controlled via RS-232C serial (PC CONTROL port, D-SUB 9P) or wired/wireless LAN (TCP port 7142). Spec covers the binary control protocol from the Sharp/NEC Projector Control Command Reference Manual: power, input switching, mutes, picture/volume/aspect adjust, lens control and memory, lamp/filter/carbon info queries, status requests, and set commands.

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: "115200/38400/19200/9600/4800"  # selectable per source
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # UNRESOLVED: flow control not explicitly stated; RTS/CTS pins wired in pin assignment table
addressing:
  port: 7142
auth:
  type: none  # inferred: no auth procedure in source

Traits

# - powerable    (015 POWER ON / 016 POWER OFF)
# - routable     (018 INPUT SW CHANGE)
# - queryable    (009/037/078/097/305 request commands)
# - levelable    (030-1 PICTURE ADJUST, 030-2 VOLUME ADJUST, 030-15 OTHER ADJUST)
traits:
  - powerable    # inferred from power command examples
  - routable     # inferred from routing command examples
  - queryable    # inferred from query command examples
  - levelable    # inferred from level control examples

Actions

# Protocol frame: command bytes in hex. Responses: 20h-23h prefix = success,
# A0h-A3h prefix = error with <ERR1> <ERR2> <CKS>.
# CKS = low-order byte of sum of all preceding bytes.

Variables

# Settable parameters are represented as parameterized Actions (030-1, 030-2,
# 030-12, 030-15, 098-8, 098-45, 098-198, 098-243-1, 319-10).
# No additional variables beyond those actions.

Events

# No unsolicited notifications documented in source.

Macros

# No multi-step sequences documented in source.

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: source contains no explicit safety warnings or interlock
# procedures. Interlock switch appears only as an error-status bit (009 DATA09 Bit1).

Notes

• Binary protocol. Command first byte by type: 00h/01h/02h/03h. Success responses prefix 20h/21h/22h/23h; error responses prefix A0h/A1h/A2h/A3h with <ERR1> <ERR2>.
• Checksum (CKS): sum all preceding bytes, take low-order byte. Example: 20h 81h 01h 60h 01h 00h → 103h → CKS 03h.
• Command bytes 3-4 are <ID1> <ID2>: ID1 = control ID set on projector, ID2 = model code. Example command frames show 00h 00h.
• Serial cable must be cross (null-modem) wired to PC CONTROL port (D-SUB 9P): pin2 RxD↔TxD, pin3 TxD↔RxD, pin5 GND, pin7 RTS↔CTS, pin8 CTS↔RTS.
• LAN: TCP port 7142 for send/receive. Some models cannot receive commands in standby mode (see manual Appendix "Standby Mode setting for receiving commands").
• POWER ON/OFF: no other command accepted during power-on, power-off, or cooling.
• Picture/onscreen mute auto-cancel on input or video signal switch; sound mute also cancels on volume adjustment.
• Lamp/filter usage times obtainable in one-second units but updated at one-minute intervals.
• Multi-byte numeric values little-endian (low byte first).
• Wireless LAN control possible via optional wireless LAN unit (see unit's operation manual).

summary: "All 53 spec actions have verbatim hex command matches in the source's section 3 command catalogue; transport values (baud, parity, port) are sourced directly. (12 unresolved item(s) noted in Known Gaps.)"

Known Gaps

- "input terminal value table, aspect value table, eco mode value table, base model type values, and PIP sub-input values are referenced to a manual Appendix (\"Supplementary Information by Command\") not present in the refined source"
- "flow control not explicitly stated; RTS/CTS pins wired in pin assignment table"
- "appendix table not in source\""
- "value list in manual Appendix not present in source\""
- "target values not enumerated in source section\""
- "sub input value table not in source\""
- "value meanings in manual Appendix not in source\""
- "source contains no explicit safety warnings or interlock"
- "appendix tables (input terminal values, aspect values, eco mode values, base model type values, PIP sub-input values, standby-mode command reception per model) referenced by source but not included in it"
- "flow control setting not explicitly stated (only pin wiring shown)"
- "default baud rate not stated (115200/38400/19200/9600/4800 all supported)"
- "ID2 model code values per model not stated"
- "source applicability inferred: the manufacturer protocol document names no model; commands verified against it but not confirmed for this exact model"
