Command : This specifies a projector ID for the projector that sends and receives commands. (individual notification) Entering 00H or FFH becomes a common command for all the projectors. (broadcast notification) This is convenient for controlling multiple projectors at the same time. * When the controller is connected with the projector on a one-to-one basis Broadcast notification is recommended.
* Data length : (12 Bit) This is data length of data portion (unit:: byte). Command : This sets data length of data added to a command to send it. ( See each command description.) Response : This sets data length of data added to a response to send it. ( See each command description.) CAUTION : Data length is specified using total of 12 bits ( 0 - 4095) of 4 bits of the 4th byte and 8 bits of the 5th byte.* The upper ranking 4 bits of the 4th byte is model code.
DATA01 Error types 00H : Not supported 01H : Parameter error 02H : Operation mode error 03H : Gain-related error 04H : Logo transfer error DATA02 Error description * When not supported 00H : Unknown command 01H : The current model does not support this function. 02H : This model is not compatible with the Switcher. 03H : This model is not compatible with the PC Viewer. * When a parameter error occurs 00H : Unvalid values specified.
* Depending on the USB host controller in the personal computer, the USB connection may fail to operate. When using a USB hub, please use a self-powered type, not a bus-powered type. When using a USB hub, connection to the first stage of the USB hub is recommended.
