Users Connecting to Serial Devices

For a user to connect to the serial device connected to the Device Server from the LAN, the Line Service must be set to Rev Telnet. The user will either access the serial device directly or go through the Easy Port Access Menu, depending on the User Level setting.

Users who are Level Admin or Normal will access the serial device directly; the user must connect to the Device Server’s IP address and port number (the DS Port parameter). The user will be asked to login with a user name and password; if this is successful, the user is automatically connected to the serial device.

Users who are Level Restricted or Menu can access the serial device through the Easy Port Access Menu, which displays the line number and name and a logout option; the user just needs to connect to the Device Server’s IP address. The user will be asked to login with a user name and password; if this is successful, the Easy Port Access Menu is displayed. Note: if the Line Service is Rev Telnet and the user uses SSH to connect to the Device Server, nothing but Logout will be displayed on the Easy Port Access Menu; the connection protocol and the Line protocol must match.

Users Connecting to the LAN

For a user to connect to the LAN through the Device Server from a serial device, the Line Service can be set to any Direct or Silent setting, plus Bidir or DSLogin.

User accounts should be created when:

zauthentication is being done locally by the Device Server.

zyou want to create predefined sessions for a user to limit that user’s access to the network.

Connecting To the Device Server

When a user connects to the Device Server, that user is authenticated and is usually set up with predefined sessions or given the opportunity to configure a Free Session to access any host using any protocol (must have a Level of at least Normal to configure a Free Session). In this example, the user must have a Line and User Service of DSLogin and DSPrompt, respectively. So, user Dennis is authenticated by the Device Server and then chooses to configure a Free Session to the HR_Server using the Telnet protocol (Dennis could have attempted to access any host on the network).

DS1 specifications

Perle Systems TS2 and DS1 are advanced serial-to-Ethernet devices designed to facilitate seamless integration of serial devices with modern IP networks. These devices serve as crucial tools for businesses looking to enhance their communication capabilities while leveraging existing infrastructure.

One of the standout features of the Perle TS2 and DS1 is their ability to support multiple serial protocols including RS232, RS422, and RS485. This versatile support allows businesses to connect various legacy devices to their networks, ensuring that critical equipment can still communicate effectively in an increasingly digital landscape.

The TS2 model is particularly noted for its dual serial ports, enabling simultaneous communication with multiple devices. This capability is invaluable for applications requiring real-time data transmission, such as remote monitoring and automated control systems. The DS1 model, on the other hand, is designed for single-port use, making it an ideal solution for smaller-scale operations or specific single-device connections.

Both the TS2 and DS1 incorporate advanced features such as configuration through a web interface, which simplifies setup and management. Users can easily access device settings and monitor performance metrics remotely, enhancing operational efficiency. These devices also support various network protocols such as TCP/IP, UDP, and ICMP, ensuring compatibility with a wide range of network architectures.

In terms of security, Perle Systems prioritize user data protection. The TS2 and DS1 offer features including SSL encryption and SSH protection, providing an added layer of security for sensitive information transmitted over the network. This is particularly important for industries where data integrity and security are paramount, such as healthcare and finance.

Additionally, the rugged design of both devices ensures reliable performance even in harsh environments. With extended temperature ratings and robust housing, the TS2 and DS1 can operate in diverse conditions without compromising functionality.

To summarize, the Perle Systems TS2 and DS1 provide a reliable and flexible solution for connecting legacy serial devices to modern networks. With their support for multiple serial protocols, web-based management, robust security features, and rugged design, these devices cater to a variety of industries looking to modernize their communication infrastructure while maintaining existing equipment. Whether for large-scale operations or smaller implementations, the TS2 and DS1 equip businesses with the tools needed for effective serial communication in an IP-driven world.
