Overview

Interface Converters, Glass Fiber to Copper Interface
Model 4159 Very High Speed Ruggedized ST Fiber to RS485 / RS422 / RS232 Interface Converter, Board Configuration

  • Four popular configurations, Fiber-to-Copper Media Converters.

Model 4159 ST Fiber-to-RS485/422/232 Copper media Converter Board

The Model 4159 Board Unit Glass Fiber to Copper converter is a very high speed ruggedized, protocol independent ST Fiber to RS485/422/232 interface converter.
Typical operating speeds are as follows: 

  • Up to 1.5 Mbps for RS232 to fiber conversion,
  • Up to 5 Mbps for RS485/422 to fiber conversion.

The Model 4159 Glass Fiber to Copper Interface Converter is designed to operate from -40°C to 85°C. Model 4159 is a member of Electro Standards Laboratories' (ESL) rugged community of glass fiber-to-copper media converters. 

The Model 4159 features protection circuitry on all receivers and transmitters for both RS232 and RS485/422 interfaces.  Model 4159/4159CC with front mounted threaded brackets for rack mounting in embedded applications. Model 4159CC is a Conformal Coated Printed Circuit Board (PCB) for military and harsh environments.

The converter is available as a desktop package (Model 4149) with optional DIN rail mounting hardware (Model 4149-DIN). 

The unit's power input is protected from transients and features 3kVDC isolation to prevent system ground loops. Model 4159 can be powered from a wide input range of 10VDC-36VDC, with modules also available for other voltage ranges such as 4.5VDC-9VDC and 19VDC-72VDC. 

Other features include user-selectable fiber polarity, TX, TX and Power indicator LEDs. There are also dual DB9 power connectors (M4159/4159CC only) for convenience in bused power applications.

Three functions in one unit:
ST Fiber to RS485 Converter
ST Fiber to RS422 Converter
ST Fiber to RS232 Converter
