Setting communication parameters for RS232

(1) Users can type a driver name in the Driver Name box. Special marks can not be used

except _.

(2) Select RS232 in the Type drop-down list box in the Connection Setup section.

(3) Select a RS232 communication port in the COM Port drop-down list box. Each item in the

COM Port drop-down list box is composed of a device name and a communication port

number. The communication ports in the COM Port drop-down list box are the same as the

communication ports in the Device Manager window.

(4) The communication format can be ASCII or RTU.

(5) The communication protocol for exchanging data through a communication port selected

must be the same as the communication protocol for exchanging data through a

communication port on a device connected. If users click Default, all communication

parameters will return to the default values.

If users do not know the communication protocol for exchanging data through a

communication port on a device connected, the users can connect the device to a RS232

communication port selected with a RS232 cable, and click Auto-detect to automatically

detect the communication protocol. If the communication protocol is detected successfully,

the related communication parameters in the Driver Properties window are set. However,

when the communication protocol is detected automatically, the COM Port parameter and

the ASCII/RTU parameter are not detected. As a result, the users have to set the COM Port

parameter and the ASCII/RTU parameter before clicking Auto-detect.

(6) Users can select the number of times the sending of a command is retried if a connection

error occurs in the Time of Auto-retry box, and select an interval of retrying the sending of

a command in the Time Interval of Auto-retry box.

*. When the Driver Properties window is opened, the information about the communication ports in the Device

Manager window is retrieved once. However, the information in the COM Port drop-down list box will not be

updated. If a device is added to the computer system after the Driver Properties window is opened, the device

will not be displayed in the COM Port drop-down list box. Users have to close the Driver Properties window,

and open it again.
