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.
Chapter
3.1.1
3.1.1 IP Address Configuration
3.1.13.1.1 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.

IP Address Configuration
IP Address ConfigurationIP Address Configuration
Page 14
SSE232-IA User’s Manual Exemys
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.
Access to configuration Web page.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.

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.

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 bits: 1, Flow control: none (9600,N,8,1)
bits: 1, Flow control: none (9600,N,8,1).

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. If you are not sure, close communication without typing the END command. >_

SSE232 IA
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.

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.

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.

Having control on this parameter, you can improve network efficiency, as long as you can send many bytes encapsulated into one Ethernet frame. However, this technique incorporates a delay, which should be carefully treated according to the serial protocol in use. If the protocol you run on the serial side does not allow any delay, time window should be configured to 0. Possible values for the time window range from 0 to 2000 milliseconds.

In the Supervision and Control port, SSE232-IA provides a way to handle inputs events. SSE232-IA can report the status of all inputs when detecting a change in one of them. If the automatic digital input report option is enabled, SSE232-IA will inform the status of all the inputs when a client connects to the TCP Port 999 and every time a change in any of the available inputs is detected. This option can be enabled or disabled according to your needs.
To enable or disable the automatic digital input report through the configuration Web page:
Select “Network” from the menu, you will see the Network configuration page. Select the Digital Input Report Enabling from the combo box. Click on the “Send” button, so the SSE232-IA may take the changes.

Server Channel with UDP Protocol Server Channel with UDP Protocol
For a channel in Server Mode, you must only configure that channel’s Port. When the transport protocol is UDP, the server channel will be “linked” to the first IP address and Port that sends a packet. The Inactivity Timeout
Inactivity Timeout parameter must also be configured, and it will work similarly as in TCP
Inactivity TimeoutInactivity Timeout mode. It will terminate the link with a specified IP address (the first to send a packet) once the predefined time lapses, thus allowing another IP address to establish communication with the UDP server channel.

When two SSE232-IA connect through an UDP Transport Protocol, one of them in Client Mode and the other in Server Mode, the SSE232-IA device running in Server mode will not send any serial data to the Client’s IP unless the client has previously sent a packet to establish communication. In other words, the SSE232-IA Server will have to receive a UDP packet from the client to be linked to that IP. After that, the data available at the serial port will be transmitted to the client’s IP. If the client fails to send a packet to the server, the server will not be able to establish a link and the data received by the corresponding serial will be lost.

The UDP mode, as different from TCP mode, allows communication between two devices configured on Client Mode. This mode shows an advantage over client-server topology, since connection can be established in both ways, disregarding which devices starts sending data. In this case, both devices must be configured in Client Mode and the IPSERV and PORTSERV of the other device must be also configured.

A.1. Device Locator Application
The Exemys Device Locator Application Program is intended to use for the basic configuration of any Exemys device over your Ethernet network. It allows to search, identify and configure the basic network parameters. This simple application program is distributed with any Exemys product in the provided CD. You can also download the latest version of this program from the Exemys Web Site (www.exemys.com). The Device Locator application must be run on a PC connected to the same network where any Exemys device is to be configured.

When the Device Locator is run for the first time it will search any Exemys device within the network. If there is an Exemys device in the network it will be shown in the Device Locator Grid:
Device: Device name, such as SSE232-IA or KIBe. Version: Firmware version running in the device. MAC Address: Hardware Ethernet Address of the device. IP: IP Address configured in the device Netmask: Subnet mask configured in the device

To refresh the grid, click on the “Query Network” button. This action will make the device Locator to search any Exemys device in the network again. You may change any of these basic network parameters within the Device Locator program. To configure any Exemys device founded by the Device Locator:
Select the device in the grid and click on the
“Properties” button, or open the “Actions” menu and select the “Properties” command. You will see the Properties dialog box.
All Exemys devices provide a Remote
Configuration Password. This password is used for the Web configuration page and remote command Console in the device. Enter this password in the “Enter current password” box if the device has a configured password.
You can type an IP Address, Netmask and
Gateway IP Address or you can click on the “Use DHCP” check box to make the device search a DHCP Server.
Click on the “Ok” button so the Device
Locator sends the updated configuration to the device.
If the password is not correct, the Device Locator will show a “Error Response from MAC
