“hhhh” and “mm” represent hours and minutes respectively. “d” and “hh” represent days and hours respectively.

“a” and “b” represent the lamp illuminating status of the LAMP 1 and LAMP 2 respectively. “hhhh” represents the operating time.

“HHHH” and “VVVV” represent the horizontal and vertical resolutions respectively. “***.**” represents the vertical frequency (in Hz) or the horizontal frequency (in kHz).

					xb1(800): Fan error
					xb2(400): Lamp error (The lamp goes out or does not
					light.)
					xb3(200): Lamp warning 1 (The lamp life has
					expired.)
					xb4(100): Lamp warning 2 (The lamp life is expiring.)
					xb5(080): Temperature error
					xb6(040): The temperature warning is being
					indicated.
					xb7(020): Lamp cover open error
					xb8(010): Filter/filter cover open error
					xb9(008): States of other component abnormality
					When only one error occurs, value shown in
					parentheses is returned.
					When multiple errors occur at the same time, the
					bits of all the occurred error are set.
					Example)
						C00: When fan error and lamp error occur at the
						same time
						180: When lamp warning 2 and temperature error
						occur at the same time

The PC sends the command without attaching the data code to it. On the other hand, the projector attaches to the received command its current operating status as the data code and send it back to the PC.
