Configuration

Configuring the Communication Port

Select Communication Port from the Management and Communication menu to display or change the communication port configuration options (see Table 3-16).

Main Menu → Configuration → Management and Communication →

Communication Port

Table 3-16. Communication Port Options (1 of 4)

Port Use

Possible Settings: Terminal, Net Link

Default Setting: Terminal

Assigns a specific use to the COM port.

NOTE: If the Default IP Destination is set to COM (see Table 3-9,Node IP Options) and you change Port Use to Terminal, the Default IP Destination is forced to None.

Terminal ± The COM port is used for the asynchronous terminal connection.

Net Link ± The COM port is the network communications link to the IP network or

IP device port.

Data Rate (Kbps)

Possible Settings: 9.6, 14.4, 19.2, 28.8, 38.4, 57.6, 115.2

Default Setting: 19.2

Specifies the rate for the COM port in kilobits per second.

9.6± 115.2 kbps ± Sets the communication port speed.

Character Length

Possible Settings: 7, 8

Default Setting: 8

Specifies the number of bits needed to represent one character.

NOTE: Character length defaults to 8 and cannot be changed if Port Use is set to

Net Link.

7 ± Sets the character length to seven bits.

8 ± Sets the character length to eight bits. Use this setting if using the COM port as the network communication link.

Parity

Possible Settings: None, Even, Odd

Default Setting: None

Provides a method of checking the accuracy of binary numbers for the COM port. A parity bit is added to the data to make the ª1º bits of each character add up to either an odd or even number. Each character of transmitted data is approved as error-free if the ª1º bits add up to an odd or even number as specified by this configuration option.

None ± Provides no parity.

Even ± Makes the sum of all 1 bits and its corresponding parity bit always even.

Odd ± Makes the sum of all 1 bits and its corresponding parity bit always odd.
