Sharp-NEC Ec091 162 Control Spec

Summary

Sharp-NEC Ec091 162 projector, controlled via RS-232C serial (PC CONTROL D-SUB 9P) or wired/wireless LAN (TCP port 7142). Covers binary framed command protocol from vendor "Projector Control Command Reference Manual" (BDT140013 Revision 7.1): power, input switching, mutes, picture/volume/aspect adjust, lens control and memory, status/information queries, eco mode, edge blending, PIP/PbP, audio select.

Events

# UNRESOLVED: source documents no unsolicited notifications; protocol is request/response only

Macros

# UNRESOLVED: no multi-step sequences documented in source

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: no explicit safety warnings or interlock procedures in source.
# Note: interlock switch state exists as error feedback bit (009 ERROR STATUS DATA09 Bit1) but no operator interlock procedure documented.

Notes

• Command frame format: <Destination> <Command code> 00h 00h <LEN> <DATA...> <CKS>. Response frames echo command code with high bit set (e.g. 02h→22h ack, A2h error; 03h→23h ack, A3h error).
• Checksum: add all preceding bytes, use low-order byte. Example: 20h+81h+01h+60h+01h+00h=103h → CKS=03h.
• ID1 = control ID set on projector; ID2 = model code, varies by model.
• POWER ON/OFF: no other command accepted while power transitioning on/off (including cooling time).
• Picture mute, onscreen mute auto-cancel on input terminal switch or video signal switch; sound mute also cancels on volume adjustment.
• Lamp/filter usage times updated at one-minute intervals though obtainable in one-second units.
• Serial cable must be cross (null-modem) wired: RxD↔TxD, RTS↔CTS, GND straight.
• LAN: TCP port 7142 for command send/receive; 10/100 Mbps auto-switchable wired, IEEE802.3/802.3u.
