SSE232-LE
Remote Configuration Console
Figure 6 - Socket-Port Scheme
The communication sockets that are in correspondence with the serial ports are flexible and
completely configurable. The SSE232-LE configured by the manufacturer so that TCP ports 1000,
1001, 1002 and 1003 are correspondent to COM A, B C y D respectively, but this may be changed
in each COM’s configuration.
As it can observed in figure 14, SSE232-LE 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 SSE232-LE inputs/outputs.
SSE232-LE configuration command console is available on Port 998.
Each of the COM–socket TCP channels can function either in Client Mode or in Server Mode.
3.2.1.1 Server
Mode
If a COM–socket channel is configured to function in server mode in a port configured by the user,
SSE232-LE will be on hold on that TCP port, waiting for a client to establish the connection (each
client will have to connect to the IP address and port of the server). Once the connection is
established, all the information received in the socket will be transmitted to the corresponding
serial port and vice-versa.
3.2.1.2 Client
Mode
When operating in client mode, each COM-socket channel will have the IP address and port of the
server they have to connect to. Thus, that channel will try to establish communication with the
server every 10 seconds and, once established, the data received in the socket will be transmitted
by the corresponding serial port and vice versa.
3.2.1.3 DTR Client Mode
DTR client mode is similar to Client Mode but in this case the SSE232-LE will way the DTR signal
to go on before trying to stablish the connection. The SSE232-LE will finish the connection if the
DTR signal goes off.
