Chapter 6: Configuring the Serial Server Properties

UDP Mode

When UDP mode is chosen, the Serial timeout, TCP alive timeout, Connection mode, Connection at, Max connection, and Remote IP address fields are replaced with the following fields: Destination IP address range, Port number, and Source IP address range. In this mode, you can configure the server to broadcast data to and receive data from multiple IP addresses. Four IP address range fields are provided.

Figure 6-4. The Server UDP Configuration screen.

Serial Timeout

Default for the Timeout property is 0, or no timeout. Setting Timeout to any value between 1 and 65535 seconds activates it. If Timeout is set to 5 seconds and the Serial Server is configured as a Server, the Client makes a connection and communications starts. If communications are ideal for 5 seconds, the Serial Server will reset and make itself available for another client connection.

TCP Alive Timeout

The Serial Server monitors TCP activity. If TCP activity stops for the length of time specified in this field, the connection will be closed. This field can be set to any value between 0 and 255 minutes. If zero, or no value, is entered into this field, the server will not disconnect.

Connection Mode

The Connection Mode field has three options: Server, Client, and Client (no heartbeat). When Client or Client (no heartbeat) is selected, the Connection at field automatically becomes active (allowing the user to select Power up or Data Arrival).

•When using the Virtual COM Port feature, select Server.

•When using a TCP or UDP Socket program, select Server.

•When using Paired Mode communication between two serial servers, set up one as a Client and the other as a Server.

•When connecting to a server that does not support Heartbeat, select Client (no Heartbeat).

Delimiter HEX 1 and Delimiter HEX 2

These fields allow the user to enter two ASCII characters (in hex format) that delimit the beginning and end of a message. When a message with both these delimiters is received at the serial port, the data contained in the serial buffer is placed in an Ethernet packet and sent out the Ethernet port. If only Delimiter 1 is set (Delimiter 2 is zero or blank), upon receiving Delimiter 1 the Serial Server will put all the data in the serial buffer in an Ethernet packet and send it out the Ethernet port. If serial data greater than 1 kilobyte is received, it will automatically be placed in an Ethernet packet and sent out the Ethernet port.

LES402A, LES401A, LES404A, 1-, 2-, and 4-Port Industrial Ethernet Serial Servers specifications

The Black Box LES402A, LES404A, and LES401A are robust industrial Ethernet serial servers designed to facilitate seamless communication between serial devices and Ethernet networks. These devices come in various configurations, including 1-port, 2-port, and 4-port options, making them suitable for a wide range of applications.

One of the primary features of the Black Box LES series is their ability to convert asynchronous serial data into a TCP/IP format. This functionality allows legacy devices to be integrated into modern Ethernet networks, providing businesses with a cost-effective solution to modernizing their infrastructure without replacing existing equipment. The devices support various serial protocols, including RS-232, RS-422, and RS-485, ensuring compatibility with numerous devices.

Each server in this series is equipped with advanced features such as selectable baud rates, which range from 300 to 921,600 bps, catering to the needs of diverse serial peripherals. Additionally, the LES402A, LES404A, and LES401A include an easy-to-use web-based management interface that simplifies configuration and monitoring. Users can quickly set up parameters, manage connections, and perform diagnostics, all from a centralized interface.

Robustness and reliability are crucial for industrial applications, and the Black Box LES series does not disappoint. Built to withstand harsh environments, these devices feature a rugged metal housing that protects against dust, moisture, and other environmental factors. Additionally, they come with Ethernet port support for Auto-MDIX, simplifying cable connections by automatically detecting and adjusting the port configuration.

Security is another significant consideration. The Black Box LES servers include features such as SSL and SSH support that secure data transmission between devices, making them suitable for sensitive applications. Furthermore, the devices support SNMP for network management, allowing for remote monitoring and management.

In summary, the Black Box LES402A, LES404A, and LES401A series of Industrial Ethernet Serial Servers are designed to bridge the gap between legacy serial devices and modern Ethernet networks. With their robust construction, varied port options, and advanced features, these devices enhance connectivity and streamline operations in demanding industrial environments.
