RS-232 MATLAB Structure Reference

You do not use all message fields in all messages. For example, a message to send data would not use the message field.RecData, but would use the field .SendData. However, knowing the possible message fields will be helpful when you are creating any of the message structures. This section contains the following topics:

• RS-232 Send/Receive Message Structure (Synchronous) -- Description of the message fields for the send/receive structure associated with RS-232 asynchronous mode and the RS-232 Send/Receive block.
• RS-232 Send Message Structure (Asynchronous) -- Description of the message fields for the send structure associated with RS-232 synchronous mode and the RS-232 Send block.
• RS-232 Receive Message Structure (Asynchronous) -- Description of the message fields for the receive structure associated with RS-232 synchronous mode and the RS-232 Receive block.
• Supported Data Types for Message Fields -- List of supported data types and the format you use to indicate those types in message fields.
