Overview

Interface Converters, ST Duplex Fiber, Multi-Point RS485/422
Fiber485® Model 4172 Very High Speed Ruggedized ST Duplex Fiber-to-Multi-Point RS485/422 Interface Converter

  • Ideal for RS485 Multi-Point Applications and Communications to Remote Sites

 The Model 4172 is a high speed ruggedized ST Duplex Fiber to RS485 / RS422 interface converter from Electro Standards Laboratories.  Typical operating speeds are up to 5 Mbps for RS485/422 to fiber conversion.  When operating in RS485/422 mode, the converter can be configured for 2-wire half duplex or 4-wire full duplex operation.

This Fiber to RS converter provides an industrial solution for applications requiring a single point-to-point or a multi-point communications link over short and long distances.  Typical applications include PC to PC long distance communications, factory automation, multi-drop data collection devices, barcode readers, time clocks, scales, data entry terminals, ATMs, toll booths and serial communications in harsh environments.

The Model 4172 Fiber to Multi-Point Converter is designed to operate from -40°C to 85°C and is a member of Electro Standards Laboratories rugged community of media converters.  This Fiber to RS converter features ESD protection circuitry on all receivers and transmitters for RS485/422 interfaces.  The unit's power input is protected from transients and features 3kVDC isolation to prevent system ground loops.  The Model 4172 media converter can be powered from a wide input range of 10VDC-36VDC, with models also available for other voltage ranges such as 4.5VDC-9VDC and 19VDC-72VDC.

Other features include user selectable fiber polarity and, also TX, RX and Power indicator LEDs.  Accessories include various AC input voltage power supplies.
