Frequently Asked Questions
What are the required RS232 communication settings?
The connection must use a Baud Rate of 19200 bps, 8 data bits, None parity, 1 stop bit, and no flow control.
How can I check the projector's current lamp hour status?
Send the Lamp-Hours command (Code: 0x2f). A successful response will have Byte0 of 0x00, with the LSB in Byte2 and MSB in Byte3.
What steps are necessary to power on the projector remotely?
The Power On command sequence is: 0xefbe, 0x10, 0x0005, 0xffc6, 0x1111, 0x0001, 0x01.
What do the response codes mean if a manual command fails?
Byte0=0x00 means Success; Byte0=0x01 indicates an Invalid Command; and Byte0=0x02 signals an Error Command (e.g., CRC error).
