Configuring Communication Settings

Before you can write or read data, both the serial port object and the instrument must have identical communication settings. Configuring serial port communications involves specifying values for properties that control the baud rate and the serial data format. These properties are given below.

Table 5-4: Serial Port Communication Properties 

Property Name	Description
BaudRate	Specify the rate at which bits are transmitted.
DataBits	Specify the number of data bits to transmit.
Parity	Specify the type of parity checking.
StopBits	Specify the number of bits used to indicate the end of a byte.
Terminator	Specify the terminator character.

Note    If the serial port object and the instrument communication settings are not identical, then you cannot successfully read or write data.

Refer to your instrument documentation for an explanation of its supported communication settings.

You can display the communication property values for the serial port object s created in Creating a Serial Port Object with the get function.

• get(s,{'BaudRate','DataBits','Parity','StopBits','Terminator'})
  ans = 
  [9600]    [8]    'none'    [1]    'LF'
