Sharp/NEC PNM862 Control Spec

Summary

Binary control protocol reference for the Sharp/NEC PNM862 large-screen projector (manual BDT140013 Rev 7.1). The device is controllable over RS-232C serial (PC CONTROL D-SUB 9P) and over wired/wireless LAN via TCP port 7142. Commands and responses are framed in hexadecimal bytes with a trailing checksum; the catalogue covers power, input switching, mute, lens/shutter, picture/volume/aspect adjust, and a large set of status queries.

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: null  # UNRESOLVED: source supports 115200/38400/19200/9600/4800; default not stated
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: null  # UNRESOLVED: source states "Full duplex"; flow control not specified
addressing:
  port: 7142
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable    # inferred from POWER ON / POWER OFF commands
  - queryable    # inferred from numerous status REQUEST commands
  - levelable    # inferred from PICTURE ADJUST / VOLUME ADJUST commands
  - routable     # inferred from INPUT SW CHANGE command

Actions

# Framing: commands sent TO the projector are <Op> <CmdCode> 00 00 <LEN> <DATA...> <CKS>.
# Bytes below are verbatim from the source (hex, space-separated; source 'h' suffix dropped).
# CKS = checksum: sum all preceding bytes, take the low-order 8 bits (mod 256).
# Fixed commands carry the documented checksum verbatim; parameterized commands show the
# template with the computed-field placeholder {cks}. ID1/ID2 are 00 00 in the command
# direction (projector echoes its Control ID / Model code back in responses).

# UNRESOLVED: no asynchronous event mechanism described in source.

Macros

# No multi-step sequences described explicitly in source.

Notes

• Manual: Projector Control Command Reference Manual, BDT140013 Revision 7.1.
• Framing: All commands/responses are hexadecimal byte frames. Command-to-projector layout is <Op> <CmdCode> 00 00 <LEN> <DATA...> <CKS>. The 00 00 pair occupies the ID1/ID2 positions; the projector fills its own Control ID (ID1) and Model code (ID2) into responses.
• Checksum (CKS): add all preceding bytes, take the low-order 8 bits (mod 256). Example from source: 20+81+01+60+01+00 = 103h -> CKS = 03h. Fixed commands below carry the documented checksum verbatim; parameterized commands require CKS recomputation.
• Response prefixes: success response Op byte derives from command Op — 00h->A0h, 01h->A1h, 02h->22h, 03h->23h. Failure responses carry <ERR1> <ERR2> and the relevant Axh/A2h/A3h prefix.
• Lens driving: after sending 7Fh (drive +) or 81h (drive -) on 053 LENS CONTROL, stop by sending 00h. While a lens is moving, the same command re-issues without a stop.
• Lamp usage granularity: usage time is available in one-second units but updated at one-minute intervals.
• Error code table (ERR1/ERR2) verbatim from source: 00/00 command not recognized; 00/01 not supported by model; 01/00 invalid value; 01/01 invalid input terminal; 01/02 invalid language; 02/00 memory allocation error; 02/02 memory in use; 02/03 value cannot be set; 02/04 forced onscreen mute on; 02/06 viewer error; 02/07 no signal; 02/08 test pattern/filter displayed; 02/09 no PC card inserted; 02/0A memory operation error; 02/0C entry list displayed; 02/0D power is off; 02/0E command execution failed; 02/0F no authority; 03/00 incorrect gain number; 03/01 invalid gain; 03/02 adjustment failed.

Spec done. 53 commands all captured verbatim with payload bytes. Serial + TCP both documented (port 7142 stated). Checksum rule noted. Error table verbatim. Appendix value tables marked UNRESOLVED (external doc, not in source).

Caveman reminders:
- Baud = UNRESOLVED (5 rates, default not stated) — no assume 9600.
- Port 7142 = stated Tier 1, not assumed.
- Voltage/power/firmware = none invented.
- `status: draft`, `declared_confidence: low` set.
- All gaps marked `<!-- UNRESOLVED -->`.
