4-2. Communication

Procedure

Communication sequence is shown below. SDCP commands must be sent by CONTROLLER and PRO-
JECTOR responses to it. On the other hand, SDAP commands are sent by PROJECTOR and have no
response from CONTROLLER.

Fig. 4-1 Command Sequence

It is prohibited that CONTROLLER send another command before receiving the response to the previous
command. Since PROJECTOR executes the command before sending the return data, CONTROLLER
must wait a while before receiving the response. The waiting time depends on not only the commands but
also network traf
