RS-232 Synchronous Mode

Use synchronous mode when you need to receive a response before continuing with other computations. In synchronous mode, data is sent to an external device and the driver block waits for a response. In other words, the I/O driver blocks or stops execution of the target application until an answer is received from the external device or it reaches a time-out. This section includes the following topics:

• Notes For RS-232 Synchronous Mode -- Overview for RS-232 communication with xPC Target blocks
• Adding RS-232 Driver Blocks (Synchronous) -- Add the setup, send, and receive blocks you need to your Simulink model for RS-232 communicating.
• Creating RS-232 Message Structures (Synchronous) -- Create the initialize, send/receive, and termination message structures you need in the MATLAB workspace.
