Chapter II Installing
2.1 Hardware Installing
2.1.1 Serial ports connections
IOLAN has 1 /2 / 4/ 8/ 16/ 32 serial ports in the form of DTE, such as RS232 /RS422
/RS485, there is an exact serial port which is the same as that of a standard PC.
According to your software, there are three ways to connect:
If you once have a line to connect the device device with PC COM port, you can directly
use the line to connect your device with the serial port in ; or you can also buy a
converter between RJ45 and DB9 to connect; in the appendix of the manual, it offers
the definition of a signal wire in . So you can design a connection line according to
your own demand.
5
2.1.2 Power Connection
Two steps to connect power:
1 Connect the DC plug of the power adapter with the DC outlet of
2 Connect the AC plug of the power adapter with your patch board in the utility power.
2.1.3 Internet Connection
IOLAN has three ways to connect Ethernet:
Generally, you can only use Internet cable or choose the HUB/SWITCH connecting line in the
“options”, one end to connect the HUB/SWITCH, the other end to connect RJ45 in .
Sometimes, the users can use , instead of HUB/SWITCH. They can use the straight-through cable
for broadcom in the , one end to connect the broadcom of the host computer, the other end to
connect RJ45 in the .
2.1.4 Indicator Light
In the front panel of , there are four indicator lights:
POWER: indicates the device connection with power
LINK/ACT: when the light is constantly on, it shows the device right connection with Ethernet;
when the light flickers, it means Ethernet is receiving and transmitting the data.
100M/10M: when the light is constantly on, it means the speed of Ethernet is 100M; when the
light is off, it shows the speed is 10M.
FULL/HALF: when the light is constantly on, it shows the full duplex mode; when the light is off,
it shows the semiduplex mode.
The Tx & Rx light in the framework represents the serial port is transmitting and receiving.
2.2 Software Installing
2.2.1 Introdction of IOLAN Working Model
An advanced serial server, it is also a converter between asynchronous serial port and Ethernet port.
It extends the serial server in computer, and makes the traditional serial device update into Internet
device. Therefore, the users control these devices by local area network, enterprise network,
metropolitan area network and even Internet.
In order to be suitable for different occasions, offers five kinds of working model: Windows
6
expended serial port mode, Socket mode, serial port PPP mode, and LPD print mode. Before you use,
you should know your own application model. And also know what kinds of applications has. Then
you can know how to connect the application environment with the application model in.
 TCP/UDP Real port (Windows extended serial ports mode)
The expended Com port driver under the Windows platform, it offers simple-to-use management
system under the Windows platform. They are no less than1024 serial ports under the Windows
NT/Windows2000/Windows XP.
In this model, each serial port of can reflect into the local COM port under the Window platform in
the host computer. This means using these serial ports is like using the local COM port in the host
computer, and it also means the current software or communication module which are used on this
serial ports can directly use without any adjustment. See details in 4.1.
 Multi screens TTY(UNIX Log-in mode)
The terminal device can use this mode to log in Linux/Unix host computer. In this mode, each serial
port can support at most six virtual screens on average. Each screen supports two ways of log in
ways: standard TELNET and RTELNET. And each screen can also log in different host computer or
the same one. By hot key command, one terminal which supports connection with different host
computer, which fully realize that one person in one terminal can undertake multitask. In the fixed
terminal mode of RTELNET, it offers Fixed TTY driver under the SCO Unix/Linux/Unix ware. The
users can log in the terminal with any names beginning with TTY, which largely eases the
management work and also easily reduce the errors. See details in 4.3.
 PPP dialout/PPP daemon（as the server or client of PPP）
Each serial port of can support PPP. By configuration, each serial port can be used as server or client
of PPP. It can support remote dial-up access service. It can be used as the dialing-in and dialing-out
server in the remote dialing-up service system. If it employs RS-232 mode from two sides, it can
also use PPP to connect, for example, the optical transmitter and receiver of RS-232. See details in
4.4.
 TCP/UDP Socket(Socket access module basis on network communication)
It provides all data and sample source code to visit basis on access Socket, which can be used to visit
and control the serial port of under the OS supporting TCP/IP. Under the TCP/UDP Socket mode,
there are tcp client, tcp server, and udp, which play a role respectively in TCP client, TCP server and
UDP function. See details in 4.2.
 Line printer daemon (Serial port work in LPD mode)
This mode focuses especially on the application of serial port printer, and also supports LPD print
queue. See details in 4.5.

Chapter III Log-in and Configuration
There are usually two ways to log in:
1. By telnet, log in under the windows platform;
2. By the first serial port or CONSOLE port (some types do not have console port) in the terminal
of serial port, log in under the UNIX / LINUX platform.
3.1 Log-in
3.1.1 Log-in under the windows platform
1. Connect power and Ethernet, if the straight-through cable directly connects with hub or switch,
if the crosswire, it will directly connect with the broad com in PC;
2. Power on, watch the light;
3. Default IP address of : 192.168.0.233 ;
4. Use tool software-htutls.exe in CD(in the directory of driver in CD) to confirm the state of the
device;
5. Click the icon
to scan the device;
6. Find the online device;
7. No matter whether and you are in the same network segment, htutls.exe can always find.
However, only in the same network, you can log in and configurate it.
8.
It is probably not in your operating network, there are two ways to connect:
1. By adding routing to connect PC with :
The default IP address of is: 192.168.0.233, suppose your IP address: 168.8.0.88
11
input: route add 192.168.0.233 168.8.0.88
Then input telnet 192.168.0.233. That is all.
2. You can use the same temporary network, which is given by htutls.exe to. Then you click the
icon it will generate a
window, then you input temporary IP address the same as PC, for
example, 168.8.0.99.
Click OK, and establish a temporary IP address to the device, at this time, you can telnet
168.8.0.99
Log-in configuration.
Of course, the easiest way is to change the temporary IP address of PC into the same as
that of , then to log in configuration.
3.1.2 Installing driver under the UXIX/LINUX platform
Use the first serial port or CONSOLE port (partial types) in the terminal to log in.
When one end of the serial port connects to 1, the other end connects with PC or terminal.

Chapter IV IOLAN Work Model
4.1 TCP Real port (Windows extended serial ports mode)
4.1.1 Configuration of IOLAN
Enter the main interface, choose the serial port, and then enter the concrete configuration
interface, also choose mode:
Reselect TCP realport (i.e. the system default)
4.1.2 Installing driver
See details in 2.2.2
4.1.3 Configurating Serial ports
See details in 3.2.2
4.2 TCP/UDP Socket Mode
Enter MAIN interface, choose the serial ports, and then enter the concrete configuration interface.
Meanwhile, choose the TCP/UDP Socket in mode:
22
Enter the interface:
Under the mode of TCP/UDP Socket, there are three protocols, i.e. tcp client, tcp server, udp, which
are looked upon respectively as TCP client, TCP server and UDP function. Among configuration
options, TCP data, CR trans to, LF trans to, sessions, and strip NULL are valid to the three protocols.
The meanings of these configuration options are explained as follows:
TCP data:
It includes two parameters, i.e. raw and telnet. Raw means the transparent transmission, i.e. IOLAN
receives data from serial ports, and then transmits to other nodes by Ethernet; telnet means socket
data is accordance with the standards of TELNET and RFC2217. IOLAN adds some control codes to
the data receiving from the serial ports according to certain rules, and then transmits to other nodes
by socket.
CR trans to：
It includes four parameters, i.e. none, cr, lf and cr-lf.
None means if IOLAN receives “Enter” from the serial ports, it will not transmit to Ethernet;
Cr means, if IOLAN receives “Enter”, it still transmits to Ethernet;
Lf means IOLAN receives “Enter” from the serial port, and then it changes into “newline” in
order to transmit to Ethernet;
Cr-lf means IOLAN receives “Enter” from the serial ports, and then it changes into “Enter” and
“newline” in order to transmit to Ethernet.
LF trans to:
It includes four parameters, i.e. none, cr, lf and cr-lf.
None means, if IOLAN receives “newline” from the serial ports, and it will not transmit to
Ethernet;
23
Lf means IOLAN receives “newline” from the serial ports, and it still transmits to Ethernet;
Cr means IOLAN receives “newline” from the serial ports and it will change into “Enter” in
order to transmit to Ethernet;
Cr-lf means IOLAN receives “newline” from the serial ports, and it will change into “Enter”
and “newline” in order to transmit to Ethernet.
Sessions:
Each serial port of IOLAN can support 1-6 sessions. Sessions refer to IOLAN receives data and
then transmits to Ethernet by socket. More than one session means, IOLAN receives data from
there serial ports and then transmits to Ethernet by more than one socket. Take the following as
examples:
Suppose we set up four sessions, the following is the configuration:
We set up the protocol of “session 1” as TCP client; and the protocol of “session 2” as TCP server;
the protocol of “session 3” as UDP; the protocol of “Session 4” as TCP server. Other parameters of
every session are listed in the above picture. We also suppose that the respective IP address of
“session 2” and “session 4” are 192.168.0.1 and 192.168.0.2. If every session has right connection
with host computer, then data, which IOLAN receives from the serial ports, can be divided into four
directions. And it will transmit into the following four nodes: 192.168.0.18, 192.168.0.1,
192.168.0.99 and 192.168.0.2 according to different protocols. It means the four nodes can fast at the
same time receive the same data. Notice: in Internet we can’t see that several host computers operate
in the same serial port.
4.2.1 TCP client
As the tcp client, IOLAN connects the internet device, such as PC in TCP/IP of Ethernet. By
configuration, then IOLAN will at the right time to connect internet address and the TCP port. After
the establishment of socket, IOLAN can transmit data which is received from the relevant serial port
by socket. On the contrary, socket receives the data and transmits to the relevant serial port.
24
Other configuration options which are related with tcp client are as follows: remote host、port、
connect、disconnect and free time. The meanings of these configuration options are listed in the
following:
Remote host:
IOLAN connects IP address
Port:
IOLAN connects TCP port.
Connect:
IOLAN connects in the following situation including always, char, dcdon and dsron:
Always means IOLAN connects immediately when power is on. And even when power is off, will
reconnect soon;
Char means the moment IOLAN receives data from the relevant serial port, the IOLAN will connect;
Dcdon means when DCD for the relevant serial port of RS-232 in IOLAN is asserted high, IOLAN
will connect;
Dsron shows when DSR for the relevant serial port of RS-232in IOLAN is asserted high, IOLAN
will connect.
Disconnection conditions
After IOLAN set up the connection with socket, the disconnection will always happen in the
following situations, including none, dcdoff, sroff and break:
None, IOLAN never disconnect actively;
Dcdoff, when DCD for the relevant serial port of RS-232 in IOLAN changes from high to low,
IOLAN will disconnect;
Dsroff, when DSR for the relevant serial port of RS-232 in IOLAN changes from high to low,
IOLAN will disconnect;
Break, when the relevant serial port of RS-232 in IOLAN receives break, IOLAN will disconnect.
25
Freetime :
Set up the freetime for disconnection automatically. If during the free time, there is no transmission
of data, IOLAN will disconnect.
Unit is second. The setup of “0” means, no matter how long the freetime is, IOLAN will never
disconnect actively. The range of this option is from 0 to 10000 seconds.
4.2.2 TCP server
IOLAN is used as Tcp server and is connected passively. An important parameter is local port. There
are also some assistant options, such as, auth and auth prompt, which are related with other options
and need other options to configurate.
Local port:
IOLAN offers TCP port which can be connected by other nodes in TCP/IP. The TCP port interrelates
with the relevant serial port in IOLAN.
Auth:
When it is connected, IOLAN needs authentication of the users. If the users and the password can’t
match, the connection will stop. In this configuration options, there are two parameters, none and
local.
None, does not need authentication;
Local, needs authentication.
Notice: when choose local, user should add the relevant user and the right to read and write the serial
ports. If there is no added user, the configuration of auth will be invalid. When you input the
nonexistent user and password, you may even connect.
Auth prompt:
26
If the option is set up yes, it will show log-in message (Login: and Password) during connecting
IOLAN.
4.2.3 UDP
Under the mode of UDP, IOLAN is not only server but also client. The relevant configuration
options are local port, remote host, and port. IOLAN not only supports point-to-point but also
multicase way to transmit like UDP.
For multicase transmission, directly input the multicast address in remote host.
4.2.4 TCP/UDP socket Sample—pair connect
Two IOLAN set up connection by means of respectively TCP server and TCP client in TCP/UDP
socket. It supports Pair Connection, i.e. paired employing, to connect the two IOLAN with Ethernet
TCP/IP, to connect the two ports with RS-232. I n this way, the two IOLAN can be connected
automatically by internet instead of PC.
Suppose there are two PLC, it will need two IOLAN to pair connect by Internet. We assert the IP
address of one IOLAN is 192.168.0.233, which can be used as tcp server, the IP address of the other
is 192.168.0.232, which can be used as tcp client.
Configuration IOLAN
1. Enter the server configuration of the first IOLAN, with the IP address of 192.168.0.233
2. Press ESC and return to main, choose serial port 1 to enter
27
Set up the mode of TCP/UDP socket
3. Set TCP server as protocol
4. Enter the server configuration of the second IOLAN, with IP address of 192.168.0.232
5. Press ESC then return main, and choose serial port 1 and enter, set the mode of TCP/UDP socket
6. Set TCP client as protocol, set IP address of remote host as192.168.0.233, and set port as 10001
7. set the serial ports parameters
Set up the serial ports parameter of the two terminals of the device, such as baud rate, data bit, and
stop bit. Make sure the parameter of IOLAN is the same as that of the device.
After the configuration, the two IOLAN can be used in the mode of pair connection.
When one server is solely used as server or client, just set up according to the above.
Notice: Pair connects can generate many sessions, so one IOLAN can have many serial ports, one of
them can be used as server, the left can be used as client, can realize the one-to-many mode.
Chapter VII Linear order of
IOLAN
It is important to use the linear order of serial port. It is related with whether the data communication
can be connected. Therefore, be careful to examine the linear order required by the purchased
device.

7.2 Make the straight-through cable for broadcom
During test or configuration, IOLAN needs to connect PC directly. You can exchange pin 1 and 3,
pin 2 and 6 in the two RJ45 plugs of the Internet cable, the other lines can be connected in a straight
line.

7.4 Basic connection of the cable of serial port 2/4/8/16/32
We usually do not need to connect all the pins of RJ45and DBX, only need three straight lines（RJ45
to receive, transmit and connect ground）, i.e.normal communication. Therefore, we recommend for
you to use in this way.
