Variables

# No discrete variable parameters outside action params - all settable via commands above.
# UNRESOLVED: appendix "Supplementary Information by Command" values not included (input terminal codes, aspect values, eco mode values, key codes referenced but full tables not in source)

Events

# UNRESOLVED: no unsolicited notifications described; all responses are synchronous to commands.

Macros

# No explicit macros described in source.

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: no explicit safety interlock procedure in source. Command notes warn against issuing commands during power on/off transitions ("While this command is turning on the power, no other command can be accepted." / "While this command is turning off the power (including the cooling time), no other command can be accepted.")

Notes

Command packet format: 20h/02h/03h/01h <ID1> <ID2> <LEN/DATA...> <CKS] — first byte indicates protocol class. All commands include ID1 (control ID set on projector), ID2 (model code), and CKS (checksum = low-order byte of sum of all preceding bytes).

Serial: 9-pin D-SUB RS-232C, full duplex. TCP: port 7142. No login/auth described.
