Sharp/NEC P555 Pc5 Control Spec

Summary

Sharp/NEC P555 Pc5 large-venue projector. Binary control protocol over RS-232C serial (D-SUB 9P, PC CONTROL port) and wired/wireless LAN (TCP). Commands are hex-framed with a trailing checksum byte. This spec enumerates all commands documented in the Projector Control Command Reference Manual (BDT140013 Rev 7.1).

Notes

• Commands use binary hex framing. Each frame ends with a checksum byte (CKS) computed as the low-order 8 bits of the sum of all preceding bytes.
• ID1 = control ID set on projector; ID2 = model code (varies by model).
• Success responses begin with 2xh (where x = command group); error responses begin with Axh carrying ERR1/ERR2.
• Power and mute commands accept no other command during their execution window.
• Full duplex communication mode over serial; TCP port 7142 for LAN.
