Ring Network Type 2-Port Serial to Fiber Converter (RS-232/422/485 All Available)

View : 47
Type : Serial to Fiber Converter
Description :

This device provides 2 ports RS232/422/485 transmission over fiber optic.

Overview

This device provides 2 ports RS232/422/485 transmission over fiber optic. Each serial port supports all three interfaces: RS232, RS422, and RS485. It supports multiple fiber optic network topologies, including point-to-point communication, linear networks, star networks, and redundant ring networks with self-healing protection. It can also create more complex network topologies based on these basic structures.

Features

The device provides 1-2 serial ports, with each port simultaneously offering RS232/422/485 interfaces (interface type can be set via DIP switches) for easy on-site service activation.

It can automatically detect and control RS-485 data flow without handshake signals to control data direction. Additionally, it can automatically detect the baud rate of the serial port signal.

It has two fiber optic lines, and in the event of a line failure, it can automatically switch between them to ensure uninterrupted communication.

The optical interfaces support three fiber optic transmission modes: multi-mode dual fiber, single-mode dual fiber, and single-mode single fiber. Optional SC/ST/FC/LC interfaces are available.

It supports multiple fiber optic network structures, including point-to-point, star, linear, and redundant ring networks. These structures can be combined to create more complex network topologies.

The serial channels can transmit asynchronous serial data with adaptive baud rates ranging from 300 to 115200bps.

The serial port interfaces provide lightning protection according to the IEC61000-4-5 standard (10/700μS): 6KV for differential mode with an impedance of 40Ω, and 6KV for common mode with an impedance of 40Ω.

The device supports a wide range of AC/DC input, it features internal isolation and redundant dual power inputs. It supports overload protection and reverse connection protection for the power supply.

It complies with industrial-grade electromagnetic compatibility requirements.

The device offers strong lightning protection, capable of withstanding lightning strikes, high voltage induction, surges, and other disturbances.

With an IP40-rated enclosure, the device can withstand harsh environmental conditions.

It can be mounted on a DIN rail or a wall.

Operating temperature from -40°C to +85°C.

It has passed the 100% burn-in testing.

5-year warranty.
