Glossary

This chapter provides definitions for IOLAN terms.

BOOTP (BOOTstrap An Internet protocol that enables a diskless workstation to discover its own IP address, the IP

Protocol)address of a BOOTP server on the network, and a file to be loaded into memory to boot the machine. This enables the workstation to boot without requiring a hard or floppy disk drive.

Community (SNMP)

An SNMP community is the group that devices and management stations running SNMP belong

 

to. It helps define where information is sent.

DHCP (Dynamic Host

A TCP/IP protocol that provides static and dynamic address allocation and management.

Configuration

 

Protocol)

 

Direct Connection

Connections that bypass the IOLAN enabling the user to log straight into a specific host. A

 

direct connection is recommended where a user logging into the IOLAN is not required.

Ethernet

A high-speed (10Mbps,100Mbps) cable technology that connects devices to a LAN, using one

 

or more sets of communication protocols.

Local Authentication

Uses the user ID and password stored within the IOLAN User database.

Modem Initialization

A series of commands sent to the modem by a communications program at start up. These

String

commands tell a modem how to set itself up in order to communicate easily with another

 

modem.

MOTD

Message of the day. This is defined by a file whose contents display when users log into the

 

IOLAN.

Multicast

The broadcasting of messages to a specified group of workstations on a LAN, WAN, or internet.

NAK (Negative

A communication control character sent by the receiving destination indicating that the last

Acknowledgment)

message was not received correctly.

Reverse Connection

Connections that originate from a host that go directly to a serial device through the IOLAN.

Silent Connection

Silent connections are the same as direct connections except that they are permanently

 

established. The host login prompt is displayed on the screen. Logging out redisplays this

 

prompt. Silent connections, unlike direct connections, however, make permanent use of pseudo

 

tty resources and therefore consume host resources even when not in use.

SNMP (Simple

A protocol for managing network devices.

Network Management

 

Protocol)

 

Subnet/Prefix Bits

Identifies the devices IP address, which portion constitutes the network address and which

 

portion constitutes the host address.

Perle Systems TS2, DS1 manual Glossary

DS1, TS2 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.
