Line Service Commands

bothinoutnone

The direction in which information is received or relayed:

zNone—UDP service not enabled.

zIn—LAN to serial. The IOLAN will listen on port value configured in the DS Port parameter for messages coming from the learned or configured port.

zOut—Serial to LAN. The IOLAN will forward data received on the serial port to the IP address range, UDP port configured for this entry.

zBoth—Messages are relayed in both directions. For messages coming from the LAN to the serial device, IOLAN will listen on the port value configured in the DS Port parameter for messages coming from the learned or configured port. For messages going from the serial device to the LAN, the IOLAN will forward the data to the IP address range and UDP port configured for this entry. If auto-learnis enabled, the IOLAN must receive a UDP message before it can send one, since the UDP port number is learned from the received message.

auto-learn

The IOLAN will only listen to the first port that it receives a UDP packet from.

Applicable when set to In or Both.

any-port

The IOLAN will receive messages from any port sending UDP packets. Applicable when set to In.

specific

The port that the IOLAN will use to relay messages to servers/hosts or the port from which the IOLAN will receive messages to be forwarded to the serial port.. This option works with any setting except None. The IOLAN will listen for UDP packets on the port configured by the DS Port parameter.

<start_IP_address>

The first host IP address in the range of IP addresses (for IPV4 or IPV6) that the

IOLAN will listen for messages from and/or send messages to.

<end_IP_address>

The last host IP address in the range of IP addresses (for IPV4, not required for IPV6) that the IOLAN will listen for messages from and/or send messages to.

Set Vmodem

Description Configures the vmodem settings for the serial line. SSL/TLS can be enabled and configured for this Line Service.

SDS, MDC specifications

Perle Systems is a leading provider of connectivity solutions, renowned for its robustness and reliability in networking hardware. Among its expansive product offerings, the MDC (Multiport Device Converter) and SDS (Serial Device Server) stand out as pivotal solutions for industries requiring seamless data communication and device management.

The Perle MDC serves as a powerful multi-port device converter, providing the ability to connect multiple serial devices to a computer network without needing a separate connection for each device. This is particularly useful in environments with limited computing resources or high device density, such as railways, manufacturing plants, or remote field operations. It is designed to convert serial communication, which is commonly used in legacy devices, into Ethernet/IP or TCP/IP protocols, ensuring that older devices can integrate into modern networks.

Main features of the MDC include its robust design for industrial environments, support for a variety of serial protocols, and multiple device connections. It supports data rates of up to 115200 bps and provides easy monitoring and configuration via a web-based interface. Additionally, the MDC incorporates advanced security features including SSL and SSH encryption, ensuring data integrity and protection against unauthorized access.

On the other hand, the Perle SDS model exemplifies advanced serial device hosting capabilities, allowing users to connect Ethernet networks to serial devices. It acts as a bridge, enabling remote devices to be configured and managed over IP networks. The SDS series is known for its versatility, supporting a range of serial communication protocols, including RS-232, RS-422, and RS-485, making it suitable for various applications such as point-of-sale systems, industrial automation, and remote monitoring.

The SDS boasts several characteristics that enhance its functionality, such as automatic device discovery, real-time monitoring, and local or cloud-based management options. Its feature set also includes traffic management capabilities, allowing the optimization of device communication by controlling the flow of data, which is critical for applications requiring high reliability and low latency.

Both the MDC and SDS benefit from a strong emphasis on ease of deployment and management. They support a range of network topologies, facilitating seamless integration into existing infrastructures. Furthermore, these devices are backed by Perle Systems' reputation for customer support and a commitment to ongoing innovation, ensuring that organizations can rely on these solutions for future growth and technological advancement.
