NEC MultiSync Series Control Spec

Summary

NEC MultiSync series projector control spec derived from the "Projector Control Command Reference Manual" (BDT140013 Revision 7.1). Covers RS-232C serial control (PC CONTROL port, D-SUB 9P) and LAN control (wired/wireless, TCP port 7142) using binary hexadecimal command frames with a checksum byte. Includes power, input switching, mute, picture/volume/aspect adjustment, lens control and memory, lamp/filter/carbon usage queries, and status/information requests.

Transport

protocols:
  - tcp
  - serial
addressing:
  port: 7142
serial:
  baud_rate: 9600  # one of 4800 / 9600 / 19200 / 38400 / 115200 bps (all listed as supported in source)
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: null  # UNRESOLVED: flow control not stated in source (RTS/CTS pins wired on PC CONTROL connector; communication mode is full duplex)
auth:
  type: none  # inferred: no auth procedure in source

Traits

# - powerable    (inferred from POWER ON / POWER OFF commands 015/016)
# - routable     (inferred from INPUT SW CHANGE command 018)
# - queryable    (inferred from extensive query command set: 009, 037, 078, 097, 305, etc.)
# - levelable    (inferred from VOLUME ADJUST 030-2 and PICTURE ADJUST 030-1)
traits:
  - powerable  # inferred from power command examples
  - routable   # inferred from routing command examples
  - queryable  # inferred from query command examples
  - levelable  # inferred from volume/gain command examples

Actions

# All command payloads are verbatim hex byte strings from the source.
# {CKS} = checksum byte: sum of all preceding bytes, low-order one byte (see Notes).
# Responses carry <ID1> (control ID) and <ID2> (model code); error responses use
# A0h-A3h prefix with <ERR1> <ERR2> (see Feedbacks: command_error).

Notes

• Command/response frames are hexadecimal byte strings. Common parameters: <ID1> control ID set on projector, <ID2> model code (varies by model), <CKS> checksum, <LEN> data length in bytes following LEN, <ERR1>/<ERR2> response error codes.
• Checksum: add all preceding bytes, use the low-order one byte of the result. Source example: 20h + 81h + 01h + 60h + 01h + 00h = 103h → CKS = 03h.
• Successful responses are returned prefixed 20h/21h/22h/23h (matching the 00h/01h/02h/03h command class) with no data part when the command does not request data, or with data added when it does. Failed responses are prefixed A0h/A1h/A2h/A3h with <ERR1> <ERR2> <CKS>.
• POWER ON (015): no other command accepted while turning on. POWER OFF (016): no other command accepted while turning off, including the cooling time.
• Picture mute (020) and onscreen mute (024) are cleared by input terminal switch or video signal switch. Sound mute (022) is additionally cleared by volume adjustment.
• Lamp usage time (037, 037-4) and filter usage time are obtainable in one-second units but updated at one-minute intervals.
• Lamp remaining life (%) is negative if the lamp replacement deadline is exceeded (037-4).
• Serial cable is a cross cable to the PC CONTROL port (D-SUB 9P; pin 2 RxD, pin 3 TxD, pin 5 GND, pin 7 RTS, pin 8 CTS). LAN: wired RJ-45 (10/100 Mbps auto-switchable, IEEE802.3/802.3u) or optional wireless LAN unit; TCP port 7142 for command send/receive.
• Remote key codes (050) are WORD values; see action params for the full 24-key list.
