Configuring Communication Settings

Before you can write or read data, both the serial port object and the device 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 10-4: 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

**Table 10-4: 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 device communication settings are not identical, then you cannot successfully read or write data.

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