Summary

Optoma UHZ68LV projector control via RS-232 serial. Source ("Optoma RS232 Protocol Function List") documents the full command catalogue: power/AV-state, source select, picture/color/color-matching adjustments, aspect/keystone/geometry, language/menu, standby options, 3D, network/SSI info queries, and IR remote-key simulation. Command frame ~<id><cmd> <value>CR (id 00=all projectors); write ack P/F, read ack Ok <value>/F.

Transport

protocols:
  - serial
serial:
  baud_rate: 19200        # default per source; supports 9600-115200, "lower baud may be recommended for long cable runs"
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none
  # FIFO: UART16550 Disable (documented but not a spec field)
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable    # inferred from Power On/Off command 000
  - queryable    # inferred from extensive read commands (124, 121, 127, 151, 122, 873, ...)
  - levelable    # inferred from continuous-range sets (brightness 0-100, volume 0-30, keystone ±40, color gains 1-199)

Actions

Notes

  • Baud rate flexibility: source states the projector supports 9600–115200 bps; default 19200. "A lower baud rate may be recommended for long cable runs."
  • Projector ID: frame byte <id> selects an individual projector (00–99); 00 broadcasts to all projectors on the bus.
  • & notation: several set commands document <value> & 2 (e.g. Power Off, AV Mute Off, Mute Off, Freeze Unfreeze, Speaker Off, Audio Out Off, High Altitude Off). This indicates both 0 and 2 are accepted Off/Cancel codes — semantics difference (if any) is not explained in source.
  • Code collisions preserved verbatim: source reuses code 450 for both Saturation (Picture menu, VGA/Video) and LAN (Standby) (Settings menu), and code 150 for several Information sub-queries distinguished by their trailing sub-parameter (15=Light Source Mode, 16=Standby Power Mode, 17=DHCP, 18=System Temperature). These collisions are reproduced as documented; do not collapse.
  • Note *1 — Info String format (response to ~00001 1CR): layout abbbbbccddddee:
    • a = Power state: 0=Off, 1=On
    • bbbbb = Light Source Life (hours) = nnnn
    • cc = Input Source: 00=None, 01=DVI, 02=VGA1, 03=VGA2, 04=S-Video, 05=Video, 06=BNC, 07=HDMI1, 08=HDMI2, 09=Wireless, 10=Component, 11=Flash drive, 12=Network Display (Presenter), 13=USB Display, 14=HDMI3/Dongle, 15=DisplayPort, 16=HDBaseT
    • dddd = Firmware Version
    • ee = Display Mode: 00=None, 01=Presentation, 02=Bright, 03=Movie, 04=sRGB, 05=User, 06=User2, 07=Blackboard, 08=Classroom, 09=3D, 10=DICOM SIM., 11=Film, 12=Game, 13=Cinema, 14=Vivid, 15=ISF Day, 16=ISF Night, 18=Blending
  • Model-name info query (cmd 151) additionally returns the Optoma model-series class code (1=SVGA, 2=XGA, 3=WXGA, 4=1080P, 5=WUXGA), not the literal "UHZ68LV" string — the UHZ68LV maps to one of these classes (resolution class); exact mapping not stated in source.
