Summary

Sharp/NEC projector (As60U Pa44Ml) control spec covering the binary command protocol documented in "Projector Control Command Reference Manual" (BDT140013 Rev 7.1). The device supports RS-232C serial control (D-SUB 9P PC CONTROL port) and TCP/IP LAN control (wired RJ-45 or wireless, TCP port 7142). Commands are framed hex byte sequences with an additive low-byte checksum.

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: [115200, 38400, 19200, 9600, 4800]  # all supported by source; one selected/configured
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: null  # UNRESOLVED: flow control not stated in source
addressing:
  port: 7142  # TCP port for LAN command send/receive, stated verbatim in source
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable    # inferred: POWER ON / POWER OFF commands present
  - queryable    # inferred: numerous status request commands returning values
  - levelable    # inferred: PICTURE ADJUST, VOLUME ADJUST, LAMP ADJUST commands present
  - routable     # inferred: INPUT SW CHANGE selects input terminal

Events

events: []
# UNRESOLVED: source describes only request/response semantics; no unsolicited
# notifications documented.

Macros

macros: []
# UNRESOLVED: source documents no multi-step command sequences.

Safety

confirmation_required_for: []
interlocks: []
# Source notes operational (not safety) constraints:
#  - POWER ON / POWER OFF reject all other commands during the on/off ramp
#    (including cooling time).
#  - "02h 0Dh" error: command rejected because power is off.
#  - Error status (009) reports interlock switch open (DATA09 bit1) and
#    portrait-cover-side-up (DATA09 bit0) - treat as device health signals.
# UNRESOLVED: no explicit safety warnings, interlock procedures, or
# power-on sequencing requirements stated in this source extract.

Notes

  • Frame format: commands begin with a leading byte (00h–03h for queries/commands, 01h for FREEZE), followed by command-specific bytes, an ID1 (control ID) / ID2 (model code) pair on responses, a LEN byte, variable DATA bytes, and a trailing CKS checksum.
  • Checksum: low-order one byte of the sum of all preceding bytes. Worked example from source: 20h 81h 01h 60h 01h 00h → 103h → CKS=03h.
  • Response prefixes: 2Xh = success (no error block), A0h/A1h/A2h/A3h = carries <ERR1> <ERR2> failure block. The leading digit of the response byte matches the command's leading digit (e.g. command 02h ... → success 22h ..., error A2h ...).
  • Lamp/filter usage times update at one-minute intervals even though stored in one-second units.
  • RS-232 cable is a cross cable wired to the PC CONTROL D-SUB 9P port (pin 2↔3 RxD/TxD, pin 7↔8 RTS/CTS, pin 5 GND).
  • LAN: wired RJ-45 (10/100 Mbps auto) or optional wireless LAN unit; TCP port 7142 for command send/receive on both.
