Line Commands

connection-method

Determines how a modem will work on the line. Select from the following options:

zDirect Connect—Indicates that there is not a modem on the line. This is the default.

zDial In—Specify this option when a user is remote and will be dialing in via modem or ISDN TA.

zDial Out—Specify this option when a modem is attached to the serial port and is being used to dial out.

zDial In/Out—Specify this option when the IOLAN is being used as a router (depending on which end of the link your IOLAN is situated and how you want to initiate the communication).

zMS Direct-Host—Specify this option when the serial port is connected to a Microsoft Guest device. Line Service must be set to PPP for this option.

zMS Direct-Guest—Specify this option when the serial port is connected to a Microsoft Host device. Line Service must be set to PPP for this option.

idle-timer

Enter a time period, in seconds, for which the Idle Timer will run. Use this timer to close a connection because of inactivity. When the Idle Timer expires, the IOLAN will end the connection. The maximum value is 4294967 seconds (about 49 days). The default value of 0 (zero) means the Idle Timer will not expire, so the connection is permanently open.

line-name

Provide a name for the line so it can be easily identified. The Remote Port Buffering logging feature uses the Line Name when creating a file on the remote NFS server.

modem-name

The name of the predefined modem that is used on this line.

pages

For DSLogin line service, this is the number of video pages the terminal supports. Valid values are 1-7. The default is 5 pages.

parity

Specifies if you are using Even, Odd, or No parity on the line. If you want to force a parity type, you can specify Mark for 1or Space for 0.

phone-number

The phone number to use when Connection Method is set to Dial Out.

rev-sess-security

Enables/disables login/password authentication, locally or externally, on reverse Telnet connections. The default is Off.

sess-time

Enter a time, in seconds, for which the Session Timer will run. Use this timer to forcibly close the session (connection). When the Session Timer expires, the IOLAN will end the connection. The default value is 0 seconds so the port will never timeout. The maximum value is 4294967 seconds (about 49 days).

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.
