Model 4042 Very High Speed Ruggedized ST Fiber to RS422 Interface Converter Designed for Serial Communications in Harsh Environments

January 24, 2017


Model 4042 High Speed Ruggedized ST Fiber to RS422 Interface Converter

Electro Standards Laboratories (ESL), Cranston, RI, has designed Model 4042, a very high speed, ruggedized, ST Fiber to RS422 Interface Converter. This model provides a compact, lightweight industrial solution for applications requiring a single point-to-point or a communications link over short and long distances.    

The Model 4042 converts ST Duplex Fiber to Copper RS422 DB9 (F) port and supports constructing an optically isolated high speed communication link between connected devices.  Typical operating speeds are up to 5 Mbps for RS422 to fiber conversion.  When operating in RS422 mode, the converter is configured for 4-wire full duplex operation.  Applications include: PC to PC long distance communications, factory automation, data collection devices, barcode readers, time clocks, scales, data entry terminals, ATM’s and serial communications in harsh environments.

The ruggedized design of Model 4042 allows the unit to operate from -40°C to +85°C and features ESD protection circuitry on the RS422 copper interface.  Provides full galvanic isolation (no metallic connection) between connected devices.  The power input is protected from transients, as well as, over voltage and over current.  The converter is powered from a +5V power supply or a +28V power supply via DB9 connector.  Other features include user selectable fiber polarity, TX, RX and Power Indicator LED’s.
