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 ta rget 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 L AN por t 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 a ny other netw ork 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, SG­3011DCL/232 will power on and sta rt 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 i s desc ribed in Chapte r 3. Har dware De scription.

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 conne ction ,
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 u ser a ssigns 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 i nformation to make the connection.
If the LAN port in SG-3011DCL/232 uses assigned IP address from DHCP server or is set to a fixed IP

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

Operation
Mode

COM
Redirector

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’.

Set interface for serial port.

For RS-232 model, it is fixed to RS-232.

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.

Troubleshooting

This section describes procedures for troubleshooting problems you may encounter with
SerialGate.

Troubleshooting Installation Problems

If you cannot access the connected ser ial device via SG-3011DCL/232, first check the ne twork
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 correc t l y 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

29

SerialGate

User Guide

 Also verify that the host computer and SerialGate are using the same subnet masks (for

 If the wrong IP address is loaded, check your network for DHCP server, and make sure that

Troubleshooting Windows Problems

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

connectivity problems). If the IP address is not correct, then check whether the loading
procedure was properly executed.

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.

the server is not set up to load wrong IP addresses into SG-3011DCL/232.

ensure you can ping SG-3011DCL/232 using the command PING x.x.x.x, where x.x.x.x
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.
