Summary

Sharp/NEC projector control spec covering RS-232C serial and wired/wireless LAN (TCP) control of the NP PA903X 41ZL. Commands are binary hex frames framed with a header, control ID, model code, length, data, and a checksum (low-order byte of the sum of all preceding bytes).

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: 9600  # source lists selectable: 115200 / 38400 / 19200 / 9600 / 4800 bps
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # UNRESOLVED: source states "Full duplex" communication mode but does not name an explicit flow-control protocol; RTS/CTS pins are present on the PC CONTROL D-SUB 9P connector
addressing:
  port: 7142  # source: "Use TCP port number 7142 for sending and receiving commands"
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable     # inferred: POWER ON (015) / POWER OFF (016) commands present
  - routable      # inferred: INPUT SW CHANGE (018) input terminal switching present
  - queryable     # inferred: many *REQUEST status/info queries present
  - levelable     # inferred: VOLUME ADJUST / PICTURE ADJUST / OTHER ADJUST level commands present

Actions

# All payloads verbatim hex from source. Checksum byte (CKS) = low-order byte of sum of
# all preceding bytes. {DATAxx} = variable data byte documented per command. {CKS} = computed
# checksum; for commands where the source documents a complete fixed frame (no variable byte),
# the literal CKS value is emitted; for parameterized commands, {CKS} is left as a placeholder.
#
# Binary frame layout:  <HDR> <ID1> <ID2> <LEN> <DATA...> <CKS>
#   HDR: command header byte (00h/01h/02h/03h). Response ACK echoes HDR|20h. Error response uses HDR|80h.
#   ID1: control ID set on projector. ID2: model code (varies by model).
#   LEN: data length (bytes) following LEN.
#   CKS: checksum = low-order 8 bits of sum of all preceding bytes.

Events

# UNRESOLVED: source documents no unsolicited push notifications. All device data is obtained
# by polling via the REQUEST commands. No event mechanism described.

Macros

# UNRESOLVED: source documents no named multi-step macro sequences. Power on/off carry
# implicit cooldown/warmup exclusion windows (no other command accepted mid-transition) but
# these are device-enforced, not client-scripted macros.

Safety

confirmation_required_for:
  - power_off  # source: during power-off including cooling time, no other command accepted
  - shutter_close  # closes lens shutter; occludes projection
interlocks:
  - "Power transition lock: while POWER ON / POWER OFF (incl. cooling) is executing, the projector accepts no other command (source 3.2, 3.3)."
  - "Portrait cover / interlock switch: error status bit (009 DATA09 Bit1) indicates interlock switch open; portrait cover side up indicated by DATA09 Bit0."
  - "Mirror/lens cover: COVER STATUS REQUEST (078-6) reports cover open/closed; COVER error flagged in 009 DATA01 Bit0 / DATA03 Bit5."
  - "Lamp replacement moratorium: flagged in 009 DATA01 Bit7 (lamp 1) / DATA03 Bit6 (lamp 2); lamp usage time exceeded limit flagged in DATA02 Bit0 / Bit7."
  - "Command authority: ERR1=02h ERR2=0Fh returned when there is no authority for the operation (source 2.4)."
# UNRESOLVED: source gives no voltage/current/power specs, no explicit external interlock wiring,
# and no power-on sequencing procedure beyond the device-enforced transition lock.

Notes

  • Binary protocol: all payloads are hex byte sequences. h suffix denotes hexadecimal. ID1 is the projector's configured control ID; ID2 is the model code (varies per model — not enumerated in this extract).
  • Checksum (CKS) = low-order byte (8 bits) of the sum of all preceding bytes in the frame. Worked example from source: 20h 81h 01h 60h 01h 00h -> sum=103h -> CKS=03h.
  • Response framing: successful ACK echoes the command header with bit5 set and bit7 cleared (e.g. cmd HDR 02h -> ack 22h). Data-bearing query responses include a DATA block whose length is given by LEN. Error responses set bit7 of the header (e.g. 02h -> A2h) and carry ERR1/ERR2.
  • Serial: selectable baud 115200/38400/19200/9600/4800 bps, 8 data bits, no parity, 1 stop bit, full duplex. RS-232C cross cable on PC CONTROL D-SUB 9P (RxD/TxD/GND/RTS/CTS wired).
  • LAN: wired RJ-45 (10/100 auto) or vendor wireless LAN unit; TCP port 7142 for command send/receive.
  • Lamp 2 (DATA01=01h in 037-4) is only valid on two-lamp projector models.
  • Signal list number returned by 078-3 is 1 less than the practical value; add 1 to obtain the human-readable list number.
  • Lamp/filter usage time available in one-second units but updated at one-minute intervals.
  • Several command parameter value lists (input terminal codes, base model type codes, aspect values, eco mode values, sub-input values) live in an appendix titled "Supplementary Information by Command" that is NOT included in the refined source extract; those enums are marked UNRESOLVED above.

Spec done. 53 commands all covered verbatim hex. Both serial + TCP (port 7142) transport. No fabrication. UNRESOLVED markers where source appendix missing.

## Known Gaps

```yaml
- "firmware version compatibility not stated in source. Input terminal value list, base model type list, and several \"Supplementary Information by Command\" appendix tables are referenced by the source but not included in the refined extract."
- "source states \"Full duplex\" communication mode but does not name an explicit flow-control protocol; RTS/CTS pins are present on the PC CONTROL D-SUB 9P connector"
- "min/max range not stated in source extract (returned dynamically by 060-1)"
- "min/max range returned dynamically by 060-1"
- "enum values not in source extract"
- "source documents no unsolicited push notifications. All device data is obtained"
- "source documents no named multi-step macro sequences. Power on/off carry"
- "source gives no voltage/current/power specs, no explicit external interlock wiring,"
- "firmware version compatibility not stated in source."
- "exact enum tables for input terminal, base model type, aspect, eco mode, and PIP/PBP sub-input not present in refined extract (live in source appendix)."
- "explicit flow-control protocol for serial not named (only \"Full duplex\" stated)."
- "wireless LAN unit model list / supported wireless standards not in this extract."
