Options

accm

 

Specifies the ACCM (Asynchronous Control Character Map) characters that should be

 

escaped from the data stream. This is entered as a 32-bit hexadecimal number with each

 

bit specifying whether or not the corresponding character should be escaped. The bits

 

are specified as the most significant bit first and are numbered 31-0. Thus if bit 17 is

 

set, the 17th character should be escaped, that is, 0x11 (XON). So entering the value

 

000a0000 will cause the control characters 0x11 (XON) and 0x13 (XOFF) to be

 

escaped on the link, thus allowing the use of XON/XOFF (software) flow control. If

 

you have selected Soft Flow Control on the Line, you must enter a value of at least

 

000a0000 for the ACCM. The default value is 00000000, which means no characters

 

will be escaped.

 

address-comp

 

This determines whether compression of the PPP Address and Control fields take

 

place on the link. The default is On. For most applications this should be enabled.

 

auth-tmout

 

The timeout, in minutes, during which successful PAP or CHAP authentication must

 

take place (when PAP or CHAP is turned On). If the timer expires before the remote

 

end has been authenticated successfully, the link will be terminated.

 

challenge-interval

 

The interval, in minutes, for which the IOLAN will issue a CHAP re-challenge to the

 

remote end. During CHAP authentication, an initial CHAP challenge takes place, and is

 

unrelated to CHAP re-challenges. The initial challenge takes place even if re-challenges

 

are disabled. Some PPP client software does not work with CHAP re-challenges, so you

 

might want to leave the parameter disabled in the IOLAN. The default value is 0 (zero),

 

meaning CHAP re-challenge is disabled.

 

cr-retry

 

The maximum number of times a configure request packet will be re-sent before

 

the link is terminated.

 

cr-timeout

 

The maximum time, in seconds, that LCP (Link Control Protocol) will wait before it

 

considers a configure request packet to have been lost.

Perle Systems MDC, SDS manual Set PPP

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.
