I/O Channel Control Commands

Show IO

Description

Shows global I/O information (for example, UDP, TruePort, Modbus). Temperature I/O

User Level

is Analog.

Admin

Syntax

show iochannel <i/o_channel>

 

show iochannel rtsctsdtrdsrdcd

Options

i/o_channel

 

Specify the channel number, for example, d2 or a4. Temperature models use Analog

 

input, so the channel numbers are a1-a4.

 

rtsctsdtrdsrdcd

 

Specify the Digital output pins (RTS or DTR) or Digital input pins (CTS, DSR, or

 

DCD).

Show IOChannel

Description

Shows I/O channel information. Temperature I/O is Analog.

User Level

Admin

Syntax

show iochannel <i/o_channel>

 

show iochannel line <number> rtsctsdtrdsrdcd

Options

i/o_channel

 

Specify the channel number, for example, d2 or a4. Temperature models use Analog

 

input, so the channel numbers are a1-a4.

 

rtsctsdtrdsrdcd

 

Specify the Digital output pins (RTS or DTR) or Digital input pins (CTS, DSR, or

 

DCD).

I/O Channel Control Commands

The I/O commands in this section are used to manually manage the I/O channels.

Digital Output

Description

Manages the Digital output channel status. Not all models have four Digital channels,

User Level

most have just two.

Admin

Syntax

iochannel d1d2d3d4ctsdsrdcd clear alarminput-latch

Options

alarm

 

Clears the alarm. Note that if the condition that tripped the alarm still exists, the alarm

 

will not look like it’s cleared, but will reflect the appropriate alarm level severity. Alarm

 

Level 0 means that the alarm has not been triggered.

 

latch-input

 

Clears the latch value.

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.
