Configuration and Operation
3.1 Getting Started
The first step consists in obtaining an IP address for the SSE232-IA by any of the following
methods:
 Using the Device Locator application program (recommended method).
 Forcing an IP address entry to the ARP table.
 Locally, by accessing the command console provided by SSE232, available on COM A.
Once SSE232-IA has an IP address, the rest of the parameters can be configured:
 By accessing the configuration web page, embedded inside the equipment
(recommended method).
 Using the TCP command console.
 Locally, by accessing the command console provided by SSE232, available on COM
A.
All configuration parameters are permanently stored and will be kept even when the equipment
shuts down. Configuration parameters may be modified at any time using any of the methods
mentioned above.
3.1.1
3.1.13.1.1
3.1.1 IP Address Configuration
IP Address ConfigurationIP Address Configuration
IP Address Configuration
SSE232-IA default configuration IP is 0.0.0.0, so when turned on, it will look for a DHCP server.
SSE232-IA tries to negotiate an IP address with a DHCP server for a maximum period of 10
seconds. If the DHCP server fails to answer in that period, SSE232-IA will show an error code
using its indicator LEDs (see Appendix) and will reattempt to contact a DHCP server 60 seconds
later. This process will be repeated indefinitely until a DHCP server dynamically assigns an IP
address to the SSE232-IA or until the user assigns an IP (static IP address). During this negotiation
process, the yellow LED is steady on.
When a static addressing method is used (e.g. DHCP server is not available in the network), a new
address can be assigned by pinging the device with its new IP.

SSE232-IA User’s Manual Exemys
www.exemys.com Rev. 4 Page14
If the SSE232-IA receives an ICMP echo request packet (ping) within 7 seconds after being turned
on, it will take the destination IP of this packet, as long as it differs from the former IP configured
in the device.
In order to use this method, an entry should be added into the ARP table of any computer
connected to the network.
The Windows ARP table must have at least one IP address other than its own in order for the ARP
command to work. Be sure the ARP table has at least one entry with the command:
arp –a
If the local machine is the only entry, send a ping to another device in the network.
Then add the entry to the ARP table of the PC, entering the following command:
arp -s 192.168.0.105 00-0B-FA-XX-XX-XX
In a Unix-like OS, the command to add an entry to the ARP table is as follows:
arp -s 192.168.0.105 00:0B:FA:XX:XX:XX
Send a ping to the IP address you added to the ARP table on the previous step, by entering the
following command:
ping 192.168.0.105 -t
The –t option will cause the ping to be continuously sent.
Turn the SSE232-IA on. The equipment will respond after a few seconds. Once the SSE232-IA
responds to the ping (ICMP echo reply), you will have access to the equipment over the network.

Access to configuration Web page.
Once an SSE232-IA has a valid IP address you may access its web page to configure the other
parameters. You must use a web browser that allows the use of JavaScript.
1. If your web browser is configured to search for a Proxy server, disable that option.
2. Type the SSE232-IA IP address in the “address” field of your browser.

SSE232-IA User’s Manual Exemys

The SSE232-IA will ask for a password. Type “admin” as user name and the password to enter.
3. You will see the SSE232-IA web page. On the left frame you will find the menu, and
on the right frame you will find the configuration page.

3.1.3 TCP Configuration Command Console.
TCP Configuration Command Console.TCP Configuration Command Console.
TCP Configuration Command Console.
The SSE232-IA supplies a command console to allow configuration by TCP in the port 998.
The device will only accept one TCP connection in this port, thus preventing it from being
configured on simultaneous consoles.
To enter the console, establish a telnet connection to port 998/TCP. In Windows, run the
following command:
telnet 192.168.0.105 998
When the connection is established, a new Telnet window will open. The SSE232-IA will show the
following welcome message:
SSE232-IA - Exemys (V2.0):
-----------------------
Password:
SSE232-IA will ask for a “Password”:
You will have three opportunities to enter your password. After that, the console will be blocked
for 5 seconds before allowing you to re-enter the password.

You can access the serial port command console by locally connecting the SSE232-IA to a
computer with an RS-232 port. You must have a serial terminal program, for example Windows
HyperTerminal.
Your communication program must be set as follows: 9600 bps, Parity: None, Data bits: 8, Stop
9600 bps, Parity: None, Data bits: 8, Stop 9600 bps, Parity: None, Data bits: 8, Stop

In order to enter this configuration mode, proceed as following:
 Connect SSE232-IA to a computer and configure a terminal program as described
above.
 Turn on SSE232-IA . During the first 7 seconds SSE232-IA will wait for the CFG
command.
 Type CFG and press ENTER. The SSE232-IA will display a welcome message on
the terminal program screen.

Once you access the console, you can change the network configuration parameters with the
following commands: IP, NETMASK, and GATEWAY. If you want to change the SSE232-IA IP
address, net mask and / or Gateway, you can enter the commands to modify these parameters.
After modifying any of these parameters you must enter the END command so the changes take
effect. When the END command is executed, the SSE232-IA will actually change the configuration
and the system will be restarted. If the console is run from a Telnet session, current
communication with the equipment will be interrupted. If you need to make further changes, you
will have to open a new TCP session. Note that if you changed the IP address of the device, your
new connection should be made to these new IP number.
 To change the IP address, enter the following command:
>ip:192.168.0.110
Ok, IP Address 192.168.0.110
NOTICE, This parameter will be accepted upon execution of the END command.
At that moment, communication with the equipment will be interrupted.

3.2.1 Introduction
IntroductionIntroduction
Introduction
The SSE232-IA maps each COM (A, B, C or D) to a communication socket. Thus, once socket
connection is established, information will be transparently transferred from the corresponding
COM to the socket and vice versa, as depicted in Figure 10.

Socket/Port Scheme
Communication sockets that are in correspondence with the serial ports are flexible and
completely configurable. The manufacturer configures the SSE232-IA so that ports 1000, 1001,
1002 and 1003 are mapped to COM A, B, C and D respectively, but this may be changed for each
COM.
As it can be observed in Figure 10, the SSE232-IA has also 3 fixed TCP ports: Supervision and
Control (Port 999), Configuration Command Console (Port 998) and HTTP Server (Port 80).
Through the Supervision and Control Port (Port 999) you will be able to supervise the status of
each channel and administer the set of inputs/outputs available on the SSE232-IA.
The SSE232-IA configuration command console is available on Port 998.
Each COM–socket connection can function either in Client Mode or in Server Mode.

3.2.1.13.2.1.1
3.2.1.1 Server Mode
Server ModeServer Mode
Server Mode
If a COM–socket channel is configured to function in Server Mode, listening in a user-configurable
port, the device will wait for a client to establish a connection. That is, the client will have to
establish a connection to that SSE232-IA endpoint
(IP address and listening port). Once the connection is established, the COM-socket mapping
makes data received from the network to be transmitted to the corresponding serial port and
vice-versa.
3.2.1.2
3.2.1.23.2.1.2
3.2.1.2 Client Mode
Client ModeClient Mode
Client Mode
When operating in client mode, each COM-socket channel must know its remote server endpoint
(IP address plus listening port) in order to establish the connection. Each channel in Client Mode
will try to connect to a master socket every 10 seconds. Once connection is established, the data
received in the socket will be transmitted by the corresponding serial port and vice versa.
