2-6. Communication Rules . When sending a command from CONTROLLER, the return Data from PROJECTOR should be received first before sending the next command. Even if the next command is sent before receiving the return Data, since PROJECTOR will not be able to receive that command, it does not return a response to CONTROLLER. Consequently, no error code is also sent. The following lists the approximate waiting times for PROJECTOR to return the return Data after CONTROLLER sends the command. . When
