We use this projector heavily.? I have had issues with hdbt but rs232 has been rock solid and we have had better success using a old sony vpl-fx51 module over sending the commands ourselves.
we? use 38400 8 data bit 1 stop bit e parity for the serial port.??? I have noticed sometimes when using a cp3n or cp4n it takes multiple upload attempts to get the processor to properly send the commands over serial but that is the only issue we see with this.
