Flow control Flow control is used in two data transmission speed of different
devices in the control of data flow technology to ensure that
two devices communicate with each other to avoid data loss.
Click the "flow control" drop-
down list box, select the flow
control parameters, the options are:
No
RTS/CTS
XON/XOFF
DTR/DSR
Working mode
It’s jointly determined by software and hardware, 3IN1
products RS232 and RS485/RS422 optional, RS485/RS422
and RS232 can be automatically identified by the hardware.
Note:
There are differences in the mode selected by different products.
FIFO Enable Enable or disable the FIFO function, if the serial device does
not support data transceiver cache FIFO, FIFO function can
be disabled to avoid data transmission errors.
RTS Ctrl RTS pin can be controlled, the options are:
Auto
Force ON
Force OFF
DTR Ctrl DTR pin can be controlled, the options are:
Auto
Force ON
Force OFF
Packing length The frame length of serial data to Ethernet data. In the set time
range, the data forwards when it is greater than or equals to
the set frame length. The value range is 0~1460. It means no

limit on data transmission length when it’ set to 0.
Note:
There are some slight deviations between the actual package length
value and the set value.
Delimiter If the packaging length or the forced transfer time is 0 and the
number of delimited characters is greater than 0, the system
would detect and process the delimiter after receiving serial
data. Every time it receives matched delimiter (or combination
of characters), the system would send out all cached serial
data via network.
Character Handing Select the method of delimiter processing. Options:
Retain: the system would send out the received delimiter
and other data via network.
Delete: the matched delimiter (or combination of
delimiter) would be deleted. The system only transmits
data except delimiter.
Transmit time If the forced transmission time is greater than 0, the system
sends the serial data received within the specified time
through a packet, in the range of 0 to 65535 ms. When the
transfer time is 0, it means that the data transmission interval
is not restricted.
Apply to all Port Check the “Apply to all port” check box to apply the current
settings to all serial ports.
"Work mode" is corresponding to the model, there are RS232, RS485, RS422 options.
If there are no matching characters, the data will be sent when the serial data cache is
full of 1460 bytes.
