Setting Up Users

zUDP Entry 3

All hosts that have an IP Address that falls within the range of 172.16.1.75 to 172.16.1.80 and who listen to Port 33009 will receive UDP data from the serial device. No UDP data will be sent to the serial device.

zUDP Entry 4

This entry is disabled since Direction is set to None.

If Direction is set to In or Both, and Port is set to 0 (zero), the Device Server will learn a host IP Address and Port number based on the first UDP packet it receives and will then only send and/or accept UDP data from that host.

Setting Up Users

You can create up to four users, in addition to the Admin user (who cannot be deleted).

A user can even represent a device, like a barcode or a card swipe device, that you want to be authenticated.

User Accounts

When a serial device (like a dumb terminal or a barcode reader) is trying to access a host through the Device Server, you will need to configure user accounts when users:

zare authenticated by the Device Server and then connect to a host.

zwant a single or multiple session(s) on a host; here they initially login to the Device Server before starting that session. The Device Server is used to configure and start the session.

When a host is accessing a serial device (like a modem or a server), you will need to configure user accounts where users:

zare using a reverse telnet connection to manage a UNIX server or a router.

User Levels

There are four User Levels: Admin, Normal, Restricted, and Menu. Setting up users is only necessary when the users are actually connecting to the Device Server. Oftentimes, the Device Server is used as a gateway to a network and the user never actually logs into the Device Server itself. Users who do log into the Device Server (Line Service set to DSLogin and User Service set to DSPrompt) will have to navigate by either the Menu or CLI (except for users with Menu privileges, who can only use the Menu).

zAdmin—Users with Admin privileges have full administrative access to the IOLAN Device Server. This is not the same as the Admin user, but has equal authority (the Admin user is a permanent, factory-set user on the IOLAN Device Server).

zNormal—Users with Normal privileges have access to the Sessions menu and associated CLI only. They can start sessions, define and predefine sessions, and can change their own user environment.

zRestricted—Users with Restricted privileges have access to a restricted Sessions menu and associated CLI; they can only open sessions predefined for them by the Admin user, but not alter their own environment or sessions. Predefined sessions can also be configured to start automatically at login.

zMenu—Users with Menu privileges have access to predefined session. All other functionality is unavailable.

When the Admin user logs into the Device Server, the prompt ends with a #, whereas all other users’ prompts ends with a $ or £, depending on the character set.

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.
