Introduction
Lantech LSC-1102B is a full set serial device within two serial ports as one is a
RS-232 port and other one is a 422/ 485 (Auto-Detective) and it provides one
socket connection port.
Lantech provides new ways of connecting legacy serial devices to a Local Area
Network (LAN) or Wide Area Network (WAN). TCP/IP serial devices are
designed to operate serial ports over 100Mbit/s Ethernet networks. The data is
transmitted via TCP/IP protocol. Therefore control is available via Ethernet,
Intranet and Internet. LSC-1102B serial device is packaged in a PVC material
case well suited for industrial environments. All serial ports operate in common
industrial configuration. The serial device can be configured as network server or
network client. In the client mode, it can be installed in network which is
protected by NAT router or firewall, without the need of a real IP address. The
firmware of LSC-1102B can be reprogrammed directly via Ethernet network to
keep up with latest network standards. Lantech LSC-1102B is one of the best
serial devices for industrial applications.

Lantech TCP/IP converters)Connect the data wires between the Lantech TCP/IP
converters and the RS-485/RS-422 device. Follow the parameter setup procedures to
configure the converter (see the following chapters).
Power Supply
LSC-1102B TCP/IP converter device is powered by a single 9Vdc (inner
positive/outer negative) power supply and 500mA of current. A suitable power supply
adapter is part of the packaging. Connect the power line to the power jack at the left
side of LSC-1102B TCP/IP converter device and put the adapter into the socket. If the
power is properly supplied, the “PWR” red color LED will be on..
Ethernet LAN Port
The connector for network is the usual RJ45. Simply connect it to your network
switch or Hub. When the connection is made, the LAN LED indicator will light.
When data traffic occurs on the network, red DATA LED indicator will blink during
data transferring and receiving.
Reset Button
If by any chance, you forget the setup password, or have incorrect settings making
Lantech TCP/IP converter inoperable. First, turn off the power. Second, use any point
tip to push this button and hold it to turn on the power at the same time for 5 second.
All the parameters will be reset to the factory default.
LED Indicators
PWR (Red):
It is a power indicator (When the power is on, the LED will be on.)
Tx (Green):
Data sent indicator (When data are sending to the network, the LED will blink.)
Rx (Red):
Data received indicator (When data are receiving to the network, the LED will blink.)
SYS (Green):
It is a device statues indicator (When Lantech TCP/IP converter is operated in normal
statues, the LED will blink once per second.)

When you finish the steps mentioned above and the LED indicators are as shown, the
converter is installed correctly. You can use the Setup Tool “CVBrowser.exe” to setup the
IP Address.
To proceed the advanced parameter setup, please use a web browser (IE or Netscape) to
continue the detailed settings.

Setting Verification
After completing the wiring and parameter setting, we should verify if the setting is
correct. This chapter will introduce how to use a single computer to test if the
converter behaves well.
The operating system can be Windows 95, 98, ME, XP, 2000. The “Hyper
Terminal” utility should be installed on your PC (see Figure 6.1). It can be found
in your Windows installation CD.
The wiring architecture is similar to “RS-232 Wiring” in chapter 3, and the “Serial
Device” is replaced by the PC’s COM 1. The same PC also plays the roll of the
Remote Host.
The following topics are covered in this chapter:

Data Transmission
Hyper Terminal for TCP/IP WinSock
Initiate a Hyper Terminal from the Start Menu in Windows (see Figure 6.1), give a
terminal name, choose an icon, and press “OK” button (see Figure 6.2).
(Figure 6.1)
(Figure 6.2)
Select “TCP/IP(Winsock)” option at the “Connect using:” field (see Figure 6.3).
(Figure 6.3)
After “OK” button is pressed, Figure 6.4 appears. Enter the converter’s IP address (e.g.
192.168.123.10) at the “Host address:” field, and the Socket port number set for the
Serial Port 1 at the “Port number:” field (e.g 4660). (The Socket type of the Serial Port
1 should be “TCP Server”.)
(Figure 6.4)
After “OK” button is pressed, Figure 6.5 appears. If the Hyper Terminal connects with
the converter successfully, the time clock at the left lower corner “Connected hh:mm:ss”
will start counting.
(Figure 6.5)
Hyper Terminal for COM Port
Initiate another Hyper Terminal as a COM Port Terminal (in Figure 6.3, select COM 1 or
other COM port instead of “TCP/IP (Winsock)”). Set the COM port Properties to be
the same as those set for the Serial Port 1 of the converter.
(Figure 6.3)
Data Transmission
When all steps described above are finished, type any characters on the COM Port
Terminal and check if the typed characters are also displayed on the TCP/IP Winsock
Terminal. Alternatively, check if the characters typed on the TCP/IP Winsock
Terminal are also displayed on the COM Port Terminal. If yes, then all settings are
correct and the converter can operate properly.

FAQ
Q. Why can’t the CVBROWSER.exe detect the converter on the network?
A. Please check
□
□
□
if the power is properly plugged to the converter.
□
□
□
if the network cable is properly connected between the converter and the Hub.
Refer to the “Hardware Installation” steps in Chapter 3.
Q. Why can’t I use IE to setup the converter?
A. Please check if the network domain of your PC is the same as that of the converter.

Firmware Upgrade
As the firmware of the converter always keeps on enhancing with latest
technologies and network standards, if your applications need the latest
release of firmware, you will receive a Win32 executable utility and a ROM
binary file to upgrade the converter firmware through network:
1. Set the target converter to have IP address in the same subnet as your
host computer.
2. In the DOS Prompt environment of Windows, execute the upgrade
utility eUpg32.exe, with the ROM file name you received as the first
parameter and the target converter IP address as the optional second
parameter. For example:
eUpg32 ROM. bin 10.0.0.123
If you omit the target IP address, the upgrade software will try to find
one automatically.
3. The upgrade will start immediately with percent finished displayed on
screen. Wait until 100% complete. Please note during upgrade, do not
stop the software or remove the power of the converter, or it will cause
permanent damage of firmware and can not be recovered.
