Industrial Grade 8 Channel Serial Data Fiber Converter

The device provides 8*RS232/422/485 in the optical fiber transmission. It supports point-to-point communications, and on this basis, the networking is a more complex network topology, with a self-healing ring network protection. The device breakthroughs contradictory legacy serial interface communication distance and speed and solves electromagnetic interference, ground loop interference, and lightning damage problems, greatly improving the reliability of data communications, security, and confidentiality.

● Based on a proprietary integrated circuit;

● Provide 1-8 independent serial ports (RS232/422/485 optional) channel, physical isolation from each other;

● The electrical interface adopts an independent power module for power supply, completely isolating the ground loop between the bus and the device. At the same time, it uses opto-electric isolation technology to isolate the internal communication and bus data signals, effectively protecting the communication equipment from interference and damage caused by power ground loops and surges;

● RS232/485/422 interface, optional three data, RS232 supports 3-wire RS232 (TXD, RXD, GND), flow control support CD, DSR, CTS;

● RS232/485/422 channels can be transmitted from 0 to 115.2KBP asynchronous serial data adaptive;

● Serial port interface lightning reach IEC61000-4-5 (8/20μS) differential mode: 6KV, impedance (2Ω); Common mode: 6KV, impedance (2Ω) standard;

● Optional AC 220V, DC -48V, DC + 24V, DC power no positive and negative points.
