Description

This command is used to inquire about the current image signal input status.

(1) For SX50: Inquiry can be made when the projector is in both the remote mode and power-on status at the

same time.
For models other than SX50: Inquiry can be made whenever the projector is in the power-on status.

(2) A “busy” response is given while the zoom or focus lens is being driven.

(Refer to the ZCONTDRV command and FCONTDRV command.)
For the "SX50," the remote mode must be established.

(3) This returns the signal status of the selected input. Use INPUT command for the input selection.
(4) Even if the status is "DISPLAYING" (image now shown), the image is not displayed during blanking.

Check the status using GET BLANK. To clear the blank status, use BLANK=OFF.

(5) Similarly, the image is not displayed during "no show".

Check the status using GET NOSHOWSTATUS.
To clear no show, execute RC NOSHOW.
