  • Page 9: Ethernet Connection

    2.3 Ethernet Connection RJ45 connector is used for the Ethernet connection. The Ethernet connection is essential for SSE232-LE to operate. It can be connected to a Hub or Switch with an standard network cable. 2.3.1 Connection through a Hub or Switch A UTP network cable is used to connect SSE232-LE to the Ethernet through a Hub or Switch.

  • Page 10: Configuration And Operation

    Configuration and Operation 3.1 Getting Started The first step consists in obtaining an IP address for SSE232-LE , by any of the following means: Using the Device Locator application program (most recommended method). Forcing an IP address entry to the ARP table.

  • Page 11: Access To Configuration Web Page

    3.1.2 Access to configuration Web page. Once SSE232-LE has a valid IP address you may access the web page to configure the rest of the parameters. You must use a web navigator that allows the use of Java Scripts. 1. If your web navigator is configured to search for a Proxy server, disable that option.

    SSE232-LE User’s Manual Exemys SSE232-LE will ask for the password to enter to the page. Type “admin” as user name and then the password to enter. 3. You will see the SSE232-LE configuration web page. On the left side, you will find the menu, and on the right side, you will find the configuration page.

  • Page 13: Configuration Of Network Basic Parameters Through The Console

    3.2.1 Introduction In SSE232-LE, each COM (A, B, C o D) corresponds to a TCP socket. Thus, once communication with any of these sockets is established, information will be transparently transferred from the corresponding COM to the socket and vice versa.

    3.2.2.2 Configuration Password Both the TCP configuration console and the web page are protected by a password. The device administrator may assign access key for these resources, thus supplying safe access to SSE232-LE configuration. To change the password through the Web page: Select “Advanced”...

  • Page 16: Table 4 - Webcfg Command

    To reset the original manufacturer’s configuration from the SSE232-LE Web page: Select “Advanced” from the menu, you will see the advanced configuration page. Click on the “Set SSE232-LE to Factory Defaults” button. A message will appear asking you to confirm the action.

    This command must be entered twice for the SSE232-LE to reset to the manufacturer’s configuration. 3.2.2.5 SSE232-LE Reset If necessary, SSE232-LE may be reset. If SSE232-LE is reset, all connections are closed and SSE232-LE returns to its initial status. To reset SSE232-LE through the Web page: Select “Advanced”...

  • Page 19: Inactivity Timeout And Automatic Reset

    Automatic Reset: In Server Mode, it may be the case that the connection of a client shuts down if this client or another one tries to connect the server channel of the SSE232-LE that has the automatic reset option enabled. SSE232-LE will abort the previous connection, allowing the new client to connect.

  • Page 20: Server Mode Channel Configuration

    3.2.5 Server Mode Channel Configuration The SSE232-LE channel configured in Server Mode will be on hold, waiting for a connection in a specified port (configurable by the user). If the connection is closed, the device will stay on hold, waiting for a new connection in that Port.

  • Page 21: Client Mode Channel Configuration

    Select the “COM A” link from the menu. Enter the values as necessary. Click on the “Send” button, so the SSE232-LE may take the changes. You may use the configuration command console to change these parameters. In the commands that allow to change these parameters you must indicate the COM you are referring to.

  • Page 22: Multidrop Mode

    SSE232-LE User’s Manual Exemys Inactivity Timeout: Time of inactivity of the link, after which SSE232-LE will consider the connection to the server terminated if no flow of information is detected. To configure these parameters through the SSE232-LE Web Page: Select the “COM A” link from the menu.

  • Page 23: Supervision And Control Port

    3.2.8 Supervision and Control Port. SSE232-LE incorporates the possibility to administer digital inputs/outputs and to supervise the status of the connection sockets linked to every channel by simple commands. The Supervision and Control Port works through a TCP connection in the port 999. Each command must end with the CR character (ASCII 13).

  • Page 24: Udp Transport Protocol

    You may select the transport protocol for the Ethernet interface. Possible protocols are: TCP and UDP. The selection of the transport protocol affects all SSE232-LE channels. Thus, if you select the TCP protocol, all the channels will use this protocol. And the same applies to the UDP protocol.

  • Page 26: Connection Between Two Udp Clients

    When two SSE232-LE connect through an UDP Transport Protocol, one of them in Client Mode and the other in Server Mode, the SSE232-LE in Server mode will not send the information received by the serial to the Client’s IP unless the client has previously sent a packet to establish communication.
