Description

/IF

com1 ...

comX

None

By default: COM1 to COM4. With some serial interface cards or adapters, it is possible to have more than COM4.

Example: "/IF=com1"

/BD

9600,

19200,

38400,

57600,

115200

57600

Baud rate in bits per second

Example: "/BD=38400"

/RS

-1, 0,

232,

422,

485

232

Sets the RS232, RS422, or RS485 protocol

Example: "/RS=485"

This parameter sets the flow control of the CTS (clear to send) and RTS (request to send) lines of the serial interface.

Possible parameter values:

= -1: PVI doesn't modify the current setting (see the interface device properties) of the CTS/RTS flow control.

= 0: Always shut off the RTS line (disables RTS flow control).

= 232: Use RTS handshake.

= 422: Always turn on the RTS line.

= 485: Turn on the RTS line at the beginning of a transfer or during the transfer.

CTS flow control is disabled whenever the parameter value >= 0.

Many USB/serial adapters (USB to serial interface) do not handle CTS/RTS flow control correctly. The parameter "/RS=0" must be specified to establish an RS232 connection using these adapters.

/PA

0 - 4

1

Parity setting

0=NOPARITY

1=ODDPARITY

2=EVENPARITY

3=MARKPARITY

4=SPACEPARITY

Default setting for NET2000 communication is "/PA=1".

/IT

0 - 60000

20

Interval timeout (msec)

Defined as the maximum time that can pass between receiving two consecutive characters. The NET2000 protocol uses this time to recognize the end of a received frame.

Example: "/IT=40"

For additional parameters, see NET2000 protocol parameters.
