SetCom Statement

Sets or displays parameters for RS-232C port.

Syntax
SetCom #portNumber [, baud ] [, dataBits ] [, stopBits ] [, parity ] [, terminator] [, HWFlow ] [, SWFlow ] [, timeOut ]

Parameters

portNumber

Specify the RS-232C port number as an integer value.

• Real Part: 1 to 8

• Windows Part: 1001 to 1008

baud

Optional. Specifies the baud rate. Valid values are: (Default: 9600)

110

300

600

1200

2400

4800

9600

14400

19200

38400

57600

115200

When using the Windows Part port, some data may drop in the baud rate of 19200 or higher.

dataBits

Optional. Specifies the number of data bits per character. Valid values are 7 and 8.

stopBits

Optional. Valid values are 1 and 2. Specifies the number of stop bits per character.

parity

Specify the parity. Valid values are O (Odd), E (Even), and N (None).

terminator

Optional. Specifies the line termination characters. Valid values are CR, LF, CRLF.

HWFlow

Optional. Specifies hardware control. Valid values are RTS and NONE.

SWFlow

Optional. Specifies software control. Valid values are XON and NONE.

timeOut

Specify the timeout time (positive real number, unit: seconds) as an expression or numeric value. If this value is 0, then there is no time out.

Description
When all the parameter is omitted, displays a communication port setting.

If the several ports are used in the communication at one time with more than 19200 baud rate, error 2929 or 2922 may occur. In this case, select the lower baud rate or avoid using several ports at one time.

When using the Windows Part port, some data may drop in the baud rate of 19200 or more.

If any data drops, select the lower baud rate or use the Real Part port.

Parameters are stored to the Compact Flash inside the Controller. When you execute SetCom, the data is written to the Compact Flash. If a data is written to the Compact Flash frequently, it may shorten the Compact Flash life. Using SetCom only when changing the parameter is recommended.
