4. Make Connection
This chapter explains how to install SG-3011DCL/232. It deals with LAN and serial connection guides
for SG-3011DCL/232 to operate together with the target serial device.
Before connection
In order to connect SG-3011DCL/232 to the network, you need to use RJ45 Ethernet port. It supports
both 10Mbps and 100Mbps Ethernet connection (auto-sensing). Since LAN port in SG-3011DCL/232
supports MDIX, it automatically detects any kind of cable. (Cross or direct LAN cable) Plug one end of
a LAN cable to SG-3011DCL/232 and the other end to a hub, switch, or any other network device.
Booting for the first time
First of all, please make sure that the power input you supply to the module is corresponding with the
SG-3011DCL/232 that you have. If an appropriate power input has been successfully supplied, SG-
3011DCL/232 will power on and start booting.
Although there is no LED to check the power status, you can check it by LEDs on the RJ45 Ethernet
port. LED status operation is described in Chapter 3. Hardware Description.
An IP address is required to access web interface in SG-3011DCL/232 command-line configuration
tool. By factory default, a static IP address is assigned to SG-3011DCL/232. After the initial connection,
you can either manually assign a different IP address or set SG-3011DCL/232 to automatically get an
IP address from a DHCP server. While this depends on your network environment and policy, it is
strongly recommended that a user assigns SG-3011DCL/232 with a unique static IP.
Make connection
In order to view current settings or modify them in SG-3011DCL/232, you need to make a Web
connection to it. IP address is required information to make the connection.
18
SerialGate
If the LAN port in SG-3011DCL/232 uses assigned IP address from DHCP server or is set to a fixed IP
address, SG-3011DCL/232 supports the following options in case that a user does not know IP
address.
Default IP Address: 192.168.0.223
The default IP address set for SG-3011DCL/232 is 192.168.0.223. To connect to this address, some
changes are needed to be made from the PC. Please refer to following example.

COM Redirector
Use the serial port of SerialGate as a virtual COM port in Windows
/2000/XP/2003/Vista/7/8.
TCP Server
SerialGate works as a socket server, waiting for the client
connection on the network. Socket number for awaiting connections
can be set in ‘Local socket port’ field. After socket connection, data
between socket and serial port will be transmitted.
TCP Client
SerialGate acts as a socket client in this mode. It tries to connect to
the server IP address and the socket number assigned when a
certain server waits for connection on the network.
All data between the socket and the serial port is transferred
untouched after the socket connection is established.
UDP Server
SerialGate works as a UDP server, waiting for UDP connection
from the client on the network.
Socket number for awaiting connections can be set in ‘Local socket
port’ field.
Once a UDP packet is received to the socket that waits for the
connection, the data is transmitted to the serial port. The data input
from the serial port is put into UDP packets, which eventually are
sent to the client.
UDP Client
When the data is input to the serial port, UDP packets are sent
using the preset IP address and the socket number of the server. IP
address and port number of the server that needs to connect are
set from the ‘Target IP/Port’.

Time
0
This needs to be set when consecutive data from the given serial
port needs to be transmitted to socket at once.
For example, if 100 bytes of character string are to be transmitted
from the serial device to a server through SerialGate, bypass is set
to 0 for the latency time. Although it provides immediate sending
through SerialGate, the server could be received a lot parts of
divided packets.
If the latency time is not 0, SerialGate will wait for the time and
check new data. If there is new data, SerialGate repeatedly wait for
the time. Otherwise, SerialGate will transfer the buffered data, but it
could not run in real time.

6. Application Example
SerialGate can be used in many practical applications in various fields. Here we present some of them.
Com Port Redirector
With COM Port Redirection, a user can use serial port connected to SerialGate on the network as if it is
a serial port on PC.
Install COM Port Redirector and set the following steps. (For installation, please refer to Com Port
Redirector manual enclosed in CD.
In the picture below, IP address of SerialGate is 192.168.0.223, and the first serial port is being used. A
user can open COM 1 and use serial device connected to SerialGate

In order to correspond to the Redirector setting of PC, change the setting in the first serial port of
SerialGate as follows.

TCP_Server (TCP/IP connection from PC to SerialGate)
In socket program from the PC, connect the first serial port of SerialGate.
Since socket number for the first port of SerialGate is default 4001, try to connect to IP address and
socket number 4001 in Serial Gate when connecting from the PC to the SerialGate. As shown below,
change the Operation Mode to TCP_Server and confirm the socket number waiting for connection.
Check the communication speed of a serial device to be connected to serial port, and set it to Com
Specification.
28
SerialGate
User Guide
TCP_Client (TCP/IP connection from SerialGate to PC)
SerialGate connects to TCP/IP through the socket program in PC.
Since it is a connection from SerialGate to a PC, change the Operation Mode to TCP_Client and
register PC’s IP address and socket number to be connected. Check the communication speed of a
serial device to be connected to serial port, and set it to Com Specification.

User Guide
Troubleshooting
This section describes procedures for troubleshooting problems you may encounter with
SerialGate.
Troubleshooting Installation Problems
If you cannot access the connected serial device via SG-3011DCL/232, first check the network
connection and cabling.
Check the physical cabling to ensure all cables are plugged in (Ethernet and DB-9 serial
cable)
If the appropriate LEDs are not illuminated, then there is probably a bad 10baseT or
100baseTX cable, or the hub port is bad. If possible, try a different cable and hub port, or
try connecting a different device to the cable.
Verify that you are using the correct values for both IP Address and Port Number.
If you are using a hub, verify that the hub port is operating correctly by trying SG-3011DCL/232
on a different port.
Troubleshooting Network Configuration Problems
If you are using TCP/IP, make sure that your computer and SG-3011DCL/232 are on the
same IP segment or can reach each other with a PING command from the host. The IP
address you assign to SG-3011DCL/232 must be on the same logical network as your host
computers (e.g., if your computer has an IP address of 192.189.207.3 and the subnet mask
of 255.255.255.0, SG-3011DCL/232 should have an IP address of 192.189.207.x, where x
is an integer between 1 and 254), or you must properly configure your router address to
work with SG-3011DCL/232.
If your SG-3011DCL/232 is set to auto or DHCP for obtaining an IP address, it is possible
that IP address in SG-3011DCL/232 can be changed. Either configure your DHCP server
to give SG-3011DCL/232 a permanent lease, or configure SG-3011DCL/232 to be on a
STATIC IP address outside the scope of the DHCP addresses.
The problem may be the result of mismatched or duplicate IP addresses. Verify that the IP
address is correctly loaded into SG-3011DCL/232 (via the displayed or printed configuration
information or through the remote console), and make sure that no other nodes on the
network have this address (duplicate addresses are the biggest cause of TCP/IP
30
SerialGate
connectivity problems). If the IP address is not correct, then check whether the loading
procedure was properly executed.
Also verify that the host computer and SerialGate are using the same subnet masks (for
example, if SG-3011DCL/232 has a subnet mask of 255.255.255.0, the host must have the
same subnet mask) or that the router is properly configured to pass data between the two
devices.
If the wrong IP address is loaded, check your network for DHCP server, and make sure that
the server is not set up to load wrong IP addresses into SG-3011DCL/232.
Troubleshooting Windows Problems
If you are having trouble accessing the connected serial device through Windows,
ensure you can ping SG-3011DCL/232 using the command PING x.x.x.x, where x.x.x.x
User Guide
is the IP address of SG-3011DCL/232. If you cannot ping SG-3011DCL/232, you will not
be able to access the serial device.
If you are running COM port redirector and the software reports an error, verify that the
correct virtual COM port is being used when the application runs. Verify that your
application’s COM port settings have been changed to use the virtual COM ports.
