Machine To Machine Connections

Serial Connection

You also need to know the serial interface specifications as follows:

zEIA-232 and its speed

zEIA-422 and its speed

zEIA-485 and

its speed

half duplex with/without echo suppression or full duplex

TX driver control is automatic or RTS

Other

The most important thing to keep in mind when configuring the hardware parameters is to make sure that they are consistent with the serial device you have connected to the port. So, if you are connecting to a modem that sends out a DSR signal, you probably want to turn the Monitor DSR option on. Following is a list of just some of the other hardware configuration options:

zData Bits—5 to 8

zStop Bits—1, 1.5, 2

zMonitor DSR—on, off

zMonitor DCD—on, off

zParity—None, Odd, Even, Space, Mark

zFlow—Software, Hardware, or None

Machine To Machine Connections

If you are using the Device Server to connect two hosts, allowing data to flow freely between them, you just need to configure the Server and the Line (no User required). In the following example, the serial device is a security Card Reader that needs to transmit and receive information to/from a host on the network that maintains the Card Reader’s application every time an employee uses an access card to attempt to gain entry to the company.

After configuring the Server parameters (Server Name, IP Address, Ethernet and Serial interfaces, etc.), the Line Service is set to Sil Raw, which creates an automatic, continuous connection between the Card Reader and its associated application on the Security host (though the Device Server), by specifying the Security host name (which must already be configured in the Device Server’s Host Table) and TCP/IP port number. Therefore, the Card Reader can make a request to the Security host card reader application for employee verification, also logging access time, employee name, etc., and the Security host application can send back a code that does or does not unlock the door.

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.
