RS485 Modem Description

Presently, many users make use of RS-232/RS-485/RS-422 serial port fiber optic Modem to solve the electromagnetic interference in engineers and to extend the RS-232/RS-485/RS-422 serial port transmission distance to several or even tens of kilometers.Since signals are transmitted over fibers and these optical signals are free of electrical conductivity, they have strong anti-interference capacity and are immune to high-voltage power or thunders.

RS485 Modem Features

* Zero-Delay automatic forwarding * Supporting three types of interfaces: RS232/485/422 * Automatic detection of serial port rate, judgment and control of data transmission direction * Working wavelength: 850 nm/1310 nm * Maximum communication rate: 500 Kbps * Optional optical interfaces: ST/SC/FC * Up to 2 kilometers in multi-mode transmission and up to 40 kilometers in single mode transmission * Broad voltage inputs: AC 100V~260V, DC -36V~72V * The interface supports 1500W surge protection and 15KV ESD protection * External power supply
