Notes

Serial baud rate is configurable: 115200/38400/19200/9600/4800 bps. Default baud rate not stated in source. TCP port 7142 used for LAN command communication. Projector supports both wired and wireless LAN connections. Input terminal values and aspect values are documented in the Appendix "Supplementary Information by Command" which is not included in this source document. Key code list includes power, menu navigation, source selection, and eco mode keys.
