Chapter 4. How to Connect

This chapter explains how to install SerialGate. It deals with LAN and serial connection guides for
SerialGate to operate together with the target serial device.

Connection Guide

In order to connect SerialGate to network, you need to use RJ45 Ethernet port. It supports both
10Mbps and 100Mbps Ethernet connection (auto-sensing). Since WAN/LAN port supports MDIX,
it automatically detects any kind of cable. (Cross or direct LAN cable) Plug one end of a LAN
cable to SerialGate and the other end to a hub, switch, or any other network device.

Powering On for the First Time

First of all, please make sure that the power input you supply to the module is corresponding with the
SerialGate model that you have. If an appropriate power input has been successfully supplied,
SerialGate will power on and start booting.
Although there is no power LED to check the status, you can check 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 SerialGate or telnet command-line configuration
tool. By factory default, a static IP address is assigned to SerialGate. After the initial connection, you can
either manually assign a different IP address or set SerialGate 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 SerialGate with a unique static IP.

18

SerialGate User Guide

Connecting to SerialGate

In order to view current settings or modify them, you need to make a Web or Telnet connection to
SerialGate. IP address is required information to make a connection.
There are two ways you can know the current IP address of SerialGate.

If WAN port in SerialGate uses assigned IP address from DHCP server or is set to a fixed IP address,
SerialGate supports the following options in case that a user does not know IP address.

1. A user can connect to the default LAN port with IP address: 10.10.1.1

2. A user can search IP address pre-set to SerialGate using “Detector” application enclosed in Utility and
Documents CD and connect to SerialGate.

WAN Default IP address: 192.168.0.223

The default IP address of SerialGate is set to 192.168.0.223. In order
to connect with this address, you need to change network
configurations so that your PC can connect to the IP 192.168.0.223.
Please refer to an example to the right side, and note that values do
not necessarily have to be identical to the example below.

LAN Default IP address: 10.10.1.1

The default IP address in SerialGate is 10.10.1.1. In order to connect
to this address, the users need to configure network settings so that
their PC can connect to the IP 10.10.1.1. Please refer to an example
to the right side, and note that values don’t necessarily have to be
identical to the example.

19

SerialGate User Guide

Serial Console Port

The SG-1160 supports console port. Connect
to the console port from the PC with a serial
cable. Run a utility such as HyperTerminal,
with following settings: 115200 bps, None
Parity, 8 Data bits, 1 Stop Bit. This will allow
the users to connect to a device.

Connection using the PortView

By running the PortView program in the Utility
and Documents CD included in the SerialGate
package, you can dynamically search all
SerialGates on the network and connect to
any of them. (For more information on
PortView, please refer to the PortView manual
in the Utility and Documents CD included in
the SerialGate package)
After running PortView, click Search button. You can view the list that is running in your network. Select
the module that you would make a connection to, and click Telnet or Web to connect to the device via
Telnet or Web, respectively.
You can modify and apply the IP address of SerialGate using this program.

Now, you are ready to connect to SerialGate! There are three options to configure SerialGate.

1) Configuration via Web Browser

The users can easily configure SerialGate with web interface, accessible from most web browser. For
more information, please refer to Chapter 5. Configuration from Web Browser.

Speed: 460.8 Kbps)

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.

TCP Broadcast

SerialGate works as a server, accepting up to 5 simultaneous
connections from socket clients. Data transmitted from SerialGate is
broadcast to each socket client.

TCP Multiplex

SerialGate works as a server, accepting up to 5 simultaneous
connections from socket clients. The difference between TCP
Broadcast and TCP Multiplex is that Multiplex allows each socket to
communicate exclusively. That is, serial data in response are only
transferred to the sender socket.

UDP Server

SerialGate User Guide

Serial settings for SerialGate are as follows.

29

Menu

Default

Descriptions

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.

Pair_Master/ Pair_Slave

It extends a serial cable between DTE and DCE to network, and
enables communication not limited to distance. Two devices are
required for this feature and set one to Pair_Master and another to
Pair_Slave. It can be used for serial communication tunneling.

MODBUS ASCII

Connect MODBUS/ASCII SLAVE using serial port and make user of
MODBUS/TCP MASTER feature using LAN port in PC. This feature
enables MODBUS media converter function. (Available for SG­1010/ALL).

User Application

A user can run own customized program. In order to run it, a user
needs to ask for application development environment to
SystemBase.

Check
Time

0

After a certain amount of time passes without any communication
after the socket connection between the given serial port and the
server is established, automatically disconnect the socket
connection. Valid from 0 to 32767 sec.

For example, if the operation mode is set to TCP Server and Alive
Check Time is configured to 10, TCP Server will listen for the client’s
connection and eventually establish a connection. Since the check
time is 10 seconds, the server will wait for 10 seconds until the client
connected to it sends any packet. If there is no data for 10 seconds,

server will quit the connection and return to the listening state. This
option is helpful in preventing communication obstacles that occur
when either SerialGate or the client quits unexpectedly (i.e. Sudden
black out, reboot, LAN cable cut, etc.). In these cases, the other part
of communication might not recognize the failure of its partner. Such
misunderstanding can cause communication errors.
If the value is set to 0, this function is disabled. Once connected
socket will be retained until explicitly disconnected.

(Only applies to TCP Client, TCP Server, TCP Broadcast, and TCP
Multiplex operation modes.)

Latency
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.

Chapter 8. Application

SerialGate can be used in many practical applications in various fields.

Serial IP Redirector

With Serial IP Redirector, a user can use a serial port connected to SerialGate on the network as
if it is a serial port in the PC. Maximum speed: 460.8Kbps

Install Serial IP Redirector and set the following steps. (For installation, please refer to Serial IP 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 Com1 and use serial device connected to SerialGate.

57

SerialGate User Guide

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

58

SerialGate User Guide

TCP_Server (TCP/IP connection from PC to SerialGate)

From the socket program in the PC, connect the first serial port of SerialGate with a socket.

Since socket number for the first port of SerialGate is 4001 by default, try to connect to SerialGate IP
address and 4001 socket number when connecting from a PC.
As shown below, change the operation mode to TCP_Server and check the socket number waiting for

connection.

Check the communication speed of a serial device to be connected to the serial port, and set it to Com

Specification.

59

SerialGate User Guide

TCP_Client (TCP/IP Connection: SerialGate to PC)

Since it is a connection from SerialGate to a PC, change the operation mode to TCP_Client and register
IP address and socket number of the PC that you want to connect.
Check the communication speed of the serial device connected to the serial port in the SerialGate, and
set it in the “Com Options”.

60

SerialGate User Guide

Pairing (Serial Line to Serial Line)

This is mainly used when the cable length between the PC and a serial device is short so a user needs
to extend the communication distance. This approach consists of two SerialGates connected in pair.

Setting for SerialGate 1

In order to perform master features, change operation mode to Pari_Master. Check the communication
speed of a PC and set it in “Com Options”, and also register the target SerialGate IP address and port
number in Remote IP/Port.

61

Setting for SerialGate 2

In order to wait for master connection, set the operation mode to Pari_Slave and register the socket
number to be connected in local socket port.

SerialGate User Guide

Chapter 9. Appendix

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 SerialGate, 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 SerialGate on

a different port.

Troubleshooting Network Configuration Problems

 If you are using TCP/IP, make sure that your computer and SerialGate are on the same IP

segment or can reach each other with a PING command from the host. The IP address you
assign to SerialGate 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,
SerialGate 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 SerialGate.

 If your Device Server is set to Auto or DHCP for obtaining an IP Address, it is possible that

the IP address of SerialGate can change. Either configure your DHCP server to give
SerialGate a permanent lease, or configure SerialGate to be on a STATIC IP address outside
the scope of the DHCP addresses.

63

SerialGate User Guide

 The problem may be the result of mismatched or duplicate IP addresses. Verify that the IP

address is correctly loaded into SerialGate (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 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 SerialGate 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 SerialGate.

Troubleshooting Windows Problems

 If you are having trouble accessing the connected serial device through Windows, ensure
