Summary

Control spec for the Sharp/NEC NP Um361X projector (manual BDT140013 Rev 7.1). Covers RS-232C serial control and wired/wireless LAN control over TCP port 7142. Binary command protocol framed with hex bytes; each command carries a 1-byte checksum equal to the low byte of the sum of all preceding bytes.

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: 9600        # source lists 115200/38400/19200/9600/4800; 9600 chosen as common default - UNRESOLVED: device's actual configured rate not fixed in source
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none     # source states Full duplex; RTS/CTS pins present but hardware flow control mode not specified - UNRESOLVED
addressing:
  port: 7142             # TCP port for LAN command send/receive (stated)
auth:
  type: none             # inferred: no auth procedure in source

Traits

traits:
  - powerable      # inferred from 015 POWER ON / 016 POWER OFF
  - queryable      # inferred from many status/error/info request commands
  - routable       # inferred from 018 INPUT SW CHANGE
  - levelable      # inferred from 030-1 PICTURE ADJUST / 030-2 VOLUME ADJUST

Actions

# All commands framed in hex. <CKS> = checksum = low byte of sum of all
# preceding bytes. <ID1> = control ID, <ID2> = model code (filled by device).
# Fixed commands show verbatim payload incl. checksum; parameterized commands
# show template with variable DATA and <CKS> placeholder.

Events

# UNRESOLVED: source describes no unsolicited notifications. All responses are

Macros

# UNRESOLVED: source documents no explicit multi-step sequences.

Safety

Notes

  • Command frame: <cmd> <ID1> <ID2> <LEN> <DATA...> <CKS>. Response prefixes: 20h/22h/23h = success ack (with/without data), A0h/A2h/A3h = error (carry ERR1/ERR2). = control ID set on projector; = model code.
  • Checksum: low byte of sum of all preceding bytes. Example given: 20h 81h 01h 60h 01h 00h sums to 103h → CKS = 03h.
  • No login/auth procedure described anywhere → auth.type inferred none.
  • While power on/off in progress, projector rejects all other commands.
  • Lamp usage time granularity: 1-second units, updated at 1-minute intervals.

Spec emitted above. 53 commands, all hex payloads verbatim, checksum rule noted. Gaps marked UNRESOLVED: appendix value tables (input terminal, eco mode, sub-input, base-model type), flow_control, active baud, firmware.
