 Step 2: Serial port settings
Baud rate:
Click “Baud rate” drop-down menu to select Baud rate 50 ~ 460800bps from the
“Baud rate” drop-down list for the serial port. The default Baud rate of the serial port is
9600bps.
Data bits:
Click “Data bits” drop-down menu to select Data bits 5, 6, 7, or 8 from the “Data bits”
drop-down list for the serial port. The default Data bits of the serial port is 8 bits.
Stop bits:
Click “Stop bits” drop-down menu to select Stop bits 1 or 2 from the “Stop bits”
drop-down list for the serial port. The default Stop bits of the serial port is 1 bit.
Parity:
Click “Parity” drop-down menu to select Parity None, Even, Odd, Mark, or Space from
the “Parity” drop-down list for the serial port. The default Parity of the serial port is None.
Flow control:
Click “Flow control” drop-down menu to select Flow control None, Hardware, or
Software from the “Flow control” drop-down list for the serial port. The default Flow control of
the serial port is None.
Mode:
Click “Mode” drop-down menu to select Mode RS232, RS422, or RS485 from the
“Mode” drop-down list for the serial port. The default Mode of the serial port is RS232.
 Step 3: Protocol timeout setting
Support protocol timeout auto-detect: Check this option to support protocol timeout
auto-detect. The Serial Device Server will automatically test the TCP connection to remote
host. If the TCP connection is idle, the TCP connection will be closed and the port will be freed
for other hosts.
Protocol timeout:
Click in “Protocol timeout” text box and type a period of Protocol timeout
assigned to the serial port on the Serial Device Server. The connection will be closed and the
port will be freed for connection with other hosts when serial port stops data transmission for a
defined period of time (Protocol timeout). The default Protocol timeout is 0ms.
 Step 4: Data Packing
Delimiter1, 2: Check this option to enable Delimiter1, 2.
Click in “Delimiter1, 2” text box and
Delimiter1, 2 assigned to the serial port on the Serial Device Server. The data will be
transmitted if the Delimiter1 is received or Delimiter1 and Delimiter2 are received.
Force transmit:
Click in “Force transmit” text box and specify Force transmit to the serial port
on the Serial Device Server. The data will be transmitted when the Force transmit is reached.
The default Force transmit of the serial port is 0 to disable Force transmit.
 Step 5: Client Network settings
Remote IP 1 ~ 8:
Click in “Remote IP 1 ~ 8” text boxes to specify IP addresses and Port
numbers of remote host computers.
Connect timeout:
Click in “Connect timeout” text box and type a period of Connect timeout
assigned to the serial port on the Serial Device Server. The connection will be closed and the
port will be freed for connection with other hosts when serial port stops data transmission for a
defined period of time (Connect timeout). The default Connect timeout is 3 seconds.
Reconnect interval:
Click in “Reconnect interval” text box and type a period of Reconnect
interval assigned to the serial port on the Serial Device Server. The connection will be
reestablished with other hosts for a defined period of time (Reconnect interval). The default
Reconnect interval is 3 seconds.
RFC2217: RFC2217 is used to establish a transparent connection between a host computer
and a serial device by mapping the serial port on the Serial Device Server to a local COM port
on the host computer. Check this option to enable RFC2217 for TCP Client Setting.
Restart Port: Check this option to restart the serial port on the Serial Device Server when you
