Configuring Users

level

The access that a user is allowed:

zAdmin—The admin level user has total access to the IOLAN. You can create more than one admin user account but we recommend that you only have one. They can monitor and configure the IOLAN.

zNormal—The Normal level user has limited access to the IOLAN. Limited CLI commands and Menu access are available with the ability to configure the user’s own configuration settings.

zRestricted—The Restricted level user can only access predefined sessions or access the Easy Port Access menu.

zMenu—The menu level user will only be able to access predefined session or access the Easy Port Access menu. The Easy Port Access allows the user to connect to the accessible line without disconnecting their initial connection to the IOLAN. Does not have any access to CLI commands.

netmask

This is used for the PPP or SLIP Service types. Only used for IPv4. If the remote user is on a subnet, enter the network’s subnet mask. For example, a subnet mask of 255.255.0.0.

line-access

Specifies the user access rights to each IOLAN device line. Options are:

zRead/Write—Users are given read and write access to the line.

zRead In—Users are given access to read only outbound data, data that is going from the IOLAN to the device.

zRead Out—Users are given access to read only inbound data, data that is going from the device to the IOLAN.

Users can read data going in both directions by selecting both the Read In and Read Out options. The onoff option is only for 1-port models. You can disable line access in 2-port + models by specifying 0 (zero).

phone-number

The phone number the IOLAN will dial to callback the user (you must have set Callback to On). Enter the number without spaces. To change the phone number, overwrite the previous entry; to clear the phone number, set it to "" (double quotes without a space).

routing

Determines the routing mode used for RIP packets on the PPP and SLIP interfaces for this user. Values are:

zNone—RIP packets are neither received nor sent by the IOLAN.

zSend—RIP packets can only be sent by the IOLAN.

zListen—RIP packets can only be received by the IOLAN.

zSend and Listen—RIP packets are sent and received by the IOLAN.

service

The type of service that the user will use.

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.
