Ch. 4 Installation
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 SerialGate’s 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.
First-Time Bootup
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 SerialGate’s web interface 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.
Connecting to SerialGate
In order to view current SerialGate’s 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 Eddy.
33
SerialGate User Guide
If SerialGate’s WAN port 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.
For SerialGate-1010/1020, SerialGate-1010(W)/ALL, SerialGate-1020(W)/All
1. A user can connect to SerialGate LAN port’s virtual IP address; “10.10.1.1”
2. A user can search IP address pre-set to SerialGate using “Detector” application enclosed in Utility &
Documents CD and connect to SerialGate.
For SerialGate-1040/1080/1160
1. A user can connect to SerialGate LAN port’s default IP address; “10.10.1.1”.
2. Connecting a serial console port to a PC’s serial port, a user can set 115,200bps and connect to a
SerialGate.
3. A user can search IP address pre-set to SerialGate using “Detector” application enclosed in Utility &
Documents CD and connect to SerialGate.
WAN Default IP address: 192.168.0.223
SerialGate’s default IP address 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 below, and note that values don’t necessarily have to be
identical to the example below.
LAN Sub IP address: 10.10.1.1
For SerialGate-1010/1020, LAN port’s virtual IP address is 10.10.1.1
while LAN port’s default IP address for SeroalGate-1040/1080/1160 is
10.10.1.1. In order to connect with this address, you need to change
network configurations so that your PC can connect to the IP
10.10.1.1. Please refer to an example below, and note that values
don’t necessarily have to be identical to the example below.
34
SerialGate User Guide
Serial Console Port

COM Redirector
Use the serial port of SerialGate as a virtual COM port in Windows
2000/XP/2003/Vista.
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
Operation
Mode
COM
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 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

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,
Keepalive
Check
Time
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.)
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
Latency
Time
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.

Ch. 8 Application
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 192.168.0.247, and the first serial port is being used. A
user can open Com 21 and use serial device connected to SerialGate.
77
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.
TCP_Server (TCP/IP connection from PC to SerialGate)
In PC’s socket program, connect the first serial port of SerialGate.
Since socket number for the first port of SerialGate is default 4001, try to connect to SerialGate’s IP
address and socket number 4001 when connecting from a PC to 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.
78
SerialGate User Guide
TCP_Client (TCP/IP Connection: SerialGate  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.
79
SerialGate User Guide
Pair (Serial Line To Serial Line)
This structure is mainly used when the cable length between PC and 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 Specification, and also register Slave SerialGate’s IP
address and port number in Remort IP/Port.
80
SerialGate User Guide
Setting for SerialGate 2 In order to wait for Master connection, set Operation Mode to Pari_Slave and
register the socket number to be connected in Local Socket Port.

SerialGate User Guide
Ch. 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 se
rial 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 p
ort, 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 Serial
Gate on a different port.
Troubleshooting Network Configuration Problems

If you are using TCP/IP, make sure that your computer and SerialGate are on the sa
me IP segment or can reach each other with a PING command from the host. The I
P address you assign to SerialGate must be on the same logical network as your ho
st computers (e.g., if your computer has an IP address of 192.189.207.3 and the sub
net 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 route
r address to work with SerialGate.

If your Device Server is set to Auto or DHCP for obtaining an IP Address, it is possi
ble that SerialGate’s IP address can change. Either configure your DHCP server to
give SerialGate a permanent lease, or configure SerialGate to be on a STATIC IP ad
dress outside the scope of the DHCP addresses.
82
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 configu
ration 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 lo
ading procedure was properly executed.

Also verify that the host computer and SerialGate are using the same subnet masks(f
or example, if SerialGate has a subnet mask of 255.255.255.0, the host must have th
e 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 s
ure 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, ens
ure you can ping SerialGate using the command PING x.x.x.x, where x.x.x.x is the IP
address of SerialGate. If you cannot ping SerialGate, 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 t
he 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.
Firmware Update using FTP
A user can upload firmware using web browser, FTP, and etc.
1) Connect to SerialGate with FTP, using correct username and password. (Default: serialgate,
99999999)
2) Issue a command ‘bi’ for binary file transfer mode. Optionally use ‘hash’ to see the data
transfer mark.
3) Issue ‘put’ command to upload the firmware file.
4) After getting a ‘Transfer complete’ message, issue a command ‘bye’ to disconnect. Now we
are ready to update the firmware.
83
SerialGate User Guide
5) Connect to SerialGate via Telnet, using correct username and password. (Default: eddy,
99999999)
6) After the login, you are already at the default directory where the firmware resides. Update
can start right away.
7) Issue a command ‘ls’ to make sure firmware files are both successfully uploaded.
8) Use ‘upgrade’ command to write this file into SerialGate’s Flash memory. Upgrade application
automatically detects whether the given firmware is kernel or file system.
9) Usage: Upgrade  (Filename is case-sensitive.)
10) Make sure ‘Flash Write OK’ and ‘Flash Verify OK’ messages are displayed.
11) Enter ‘reboot’ to restart SerialGate. Now SerialGate will run with the new firmware.
