Notes

• Command format: 20h 88h 0Ch -
• ID1 = Control ID set for projector; ID2 = Model code (varies by model)
• Checksum (CKS): low-order byte of sum of all preceding bytes
• Response format: A0h/22h/23h or A2h/A3h 02h
• Power on/off commands block other commands during execution (including cooling time)
• Picture/Sound/Onscreen mute auto-cleared on input switch, video signal switch, or volume adjustment
• Lens drive commands can be issued continuously without stop; send Stop (00h/FFh) to halt
• Lamp usage time updated at 1-minute intervals despite 1-second resolution
• Serial cable: cross cable required (PC CONTROL port D-SUB 9P)
• LAN: IEEE802.3 (10BASE-T) / IEEE802.3u (100BASE-TX, Auto-Negotiation)
• Data rate: Auto switchable 10/100 Mbps
