VPort 254 User’s Manual System Configuration

4-39

Port Settings (only available in Serial Device Control)

Setting Description Default

Operation Mode

Select the serial device control operation

modes via the TCP/IP network: Real COM

Mode, TCP Server Mode, TCP Client Mode

Real COM Mode

Inactivity time

(Only available in

TCP Server Mode,

TCP Client Mode)

The VPort automatically closes the TCP

connection if there is no serial data activity for

the given time (0 to 65535 milliseconds). After

the connection is closed, the VPort starts

listening for another host’s TCP connection.

Data Packing (only available in Serial Device Control)

Setting Description Default

Delimiter 1

Delimiter 2

Once the VPort receives both delimiters

through its serial port, it immediately packs all

data currently in its buffer and sends it to the

VPort’s Ethernet port.

The setting value of the delimiter is from 00 to

FF. In addition, both delimiters can be enabled

or disabled.

Disable

Force Transmit

This parameter defines the time interval during

which the VPort fetches the serial data from its

internal buffer. If data is incoming through the

serial port, the VPort stores the data in the

internal buffer. The VPort transmits data stored

in the buffer via TCP/IP, but only if the internal

buffer is full or if the force transmit time

interval reaches the time specified under Force

Transmit timeout.

The time interval can be set from 0 to 65535

milliseconds. Set the time interval to 0 to

disable force transmit timeout.

NOTE

Delimiter 2 is optional. If left blank, then Delimiter 1 alone trips clearing of the buffer. If the size

of the serial data received is greater than 1 KB, the VPort will automatically pack the data and

send it to the Ethernet. However, to use the delimiter function, you must at least enable Delimiter

1. If Delimiter 1 is left blank and Delimiter 2 is enabled, the delimiter function will not work

properly.

TCP Server Mode (only available in Serial Device Control andTCP Server Mode)

Setting Description Default

Local TCP port

The TCP port that the VPort uses to

listen to connections, and that other

devices must use to contact VPort. The

settings should be from 1 to 65535.
