Product OverviewProduct Overview
Product Overview
SSE232-LE is a serial interface RS-232 / RS-485 to Ethernet converter and vice versa. It allows the access,
through Ethernet, to devices such as alarm panels, data acquisition, PLCs or any serial interface device.
The device is the interface between the serial communication device and the Ethernet network, acting as
a transparent converter.
SSE232-LE is then, a complete solution for Ethernet connectivity of devices with serial port (RS-232 / RS-
485).

SSE232-LE configuration is done through a configuration web page connecting the device to the Ethernet
network on which it is going to work.
To access to the configuration web page, you must connect SSE232-LE to ethernet network and install
Exemys Device Locator software.
Download the Exemys Device Locator :
http://www.exemys.com/beta/software/edl_setup.exe
Once the device is connected, this will search for a DHCP server to obtain an IP address automatically. We
will search for it using the Exemys Device Locator software, which allows us to search, identify and
configure the basic network parameters. The rest of the configuration is done from the configuration web
page of the device.
In case you do not have a DHCP server, the Exemys Device Locator will find the device with IP
address 0.0.0.0, as shown in the figure below.
If you do not have a DHCP server, give it an IP address using the Exemys Device Locator button or
using the methods explained in Appendix C

SSE232-LE sends all the data received by its serial port to the established TCP or UDP connection

port before sending them to the network. For this you can use two criteria: Silence

device, you may need to
install a Serial Port Redirector on your computer. This software will create a virtual COM port on your
computer to use an existing software as if you were connected to the computer using a physical COM
port.
The redirector software currently recommended by Exemys for this application is the Serial / IP by Tactical
Software. To download a 30-day trial or purchase a license contact [email protected].
For this mode you must configure SSE232-LE in TCP server mode. In the redirector you must indicate the
IP address of the SSE232-LE and the port (usually the 10000 port).
If you use a serial port redirector with Telnet – RFC2217 support (For example Serial/IP), you can use the
automatic port parameters configuration feature. If you do it, the serial port redirector will configure the
SSE232-LE serial port (Baud rate, data bits, parity and stop bits) automatically.
To test if the connection is correct you can press the button "Configuration Wizard"
If the SSE232-LE firmware version is previous to V3.8 or if you choose manual configuration, select “Raw

In a point-to-point connection in Client-Server TCP, a permanent link is established between two SSE232.
Received data on a serial port will be output from the remote serial port and vice versa.
The configuration is simple, one SSE232-LE is configured as server and the other as client, indicating the
IP address of the first one.

In point-to-point connection in UDP Client-Client, once the link between two SSE232 is established, the
received data in a serial port will be sent by the remote serial port and vice versa. The operation is very
similar to the TCP serial tunnel.
You can also make a connection in UDP Client - Server, but this one presents a disadvantage. If the
SSE232 configured in server mode receives data on its serial port, before receiving data from the client
SSE232, the data will be lost because it will not know where to send the data. This happens because UDP
is a protocol that does not establish connections prior to the sending of data as if it happens in TCP.
The following figure shows a UDP Client-Client configuration.

This setting is used when you want to send data from a serial port to multiple destinations and all of
them remote points can respond to the central "point".
In this case the central SSE232 must be configured in UDP Broadcast Client mode and the other points in
client mode but indicating the IP address of the central SSE232. All of them must share the same Port and
Local Port number.

In this configuration, incoming data to any SSE232-LE serial port will output through all the serial ports of
the other SSE232s. That means its operation is like RS-485 network but using the Ethernet network as
transport.
Here all devices must be configured in UDP Broadcast Client mode with the same Port and Local Port
number.
