Frequently Asked Questions
What physical pins are used for transmitting (TXD) and receiving (RXD) data on the projector?
TXD connects to Pin 2, and RXD connects to Pin 3 using the RS232 port.
What required communication settings must I use when connecting the projector via serial cable?
The settings require a Baud Rate of 19200 bps, Data Bits of 8 bits, Parity None, and Stop Bits of 1 bit.
If a command is executed incorrectly, what error response code should I look for?
A Projector Response message with Byte0 having the value `0x02` indicates an Error Command, potentially due to CRC issues or unknown commands.
