Safety

confirmation_required_for: []
interlocks: []
notes: |
  Warm Up and Cool Down phases: do not send other commands during these states.
  Factory reset requires projector reboot to clear parameters.
  Power Off requires LAN control settings / Standby LAN Control set to ON for LAN reboot.
  Response 0x00 0x14 0x00 0x00 0x00 0x14 at first byte indicates function is disabled (greyed out).

Notes

• Connector: DSUB 9-Pin male, pins 2(RXD), 3(TXD), 5(GND). Crossover (null modem) cable required if needed.
• LAN format: replace hex "0x" prefix with "" for TCP commands on port 4661. Exception: Pro9 series uses RS232 codes and port 23.
• Baud rates supported: 4800, 9600, 19200 (default), 38400.
• Write command acknowledgment: 03 14 00 00 00 14
• Read command response: 05 14 00 03 00 00 00 {value_byte} {checksum}
• Functions greyed out in OSD respond with 00 14 00 00 00 14 indicating disabled state.
• Mute only active when input source is applied.
• Source entries 60-61 and 81-83 in original table are duplicates of Freeze and Volume commands respectively.
