Events

# UNRESOLVED: source describes no unsolicited notifications; projector only
# responds to commands. Device-initiated events not documented.

Macros

# UNRESOLVED: no multi-step sequences described in source.

Safety

confirmation_required_for: []
interlocks: []
# Source notes interlock-related bits in error status (DATA09 Bit1 = interlock
# switch open; DATA04 Bit7 = lens not installed properly) but documents no
# safety procedure, power-on sequencing requirement, or confirmation rule.
# <!-- UNRESOLVED: no safety warnings or interlock procedures stated in source -->

Notes

  • Manual revision: BDT140013 Rev 7.1.
  • Communication mode: full duplex. RS-232C-compliant serial (cross cable, D-SUB 9P PC CONTROL port). Baud selectable: 115200 / 38400 / 19200 / 9600 / 4800 bps.
  • LAN: wired RJ-45 (10/100 Mbps auto) or wireless LAN unit. TCP port 7142.
  • Command frame format: <prefix> <ID1> <ID2> <LEN> <DATA??...> <CKS>. Prefix 00h/01h/02h/03h = command (varies), 20h/21h/22h/23h = success response, A0h/A1h/A2h/A3h = error response.
  • Checksum: sum all preceding bytes, take low-order 8 bits.
  • During power-on ramp and power-off cooling, no other command accepted.
  • Picture/onscreen mute cleared by input/video switch. Sound mute also cleared by volume adjust.
