Overview

Interface Converters, Glass Fiber to Copper
Very High Speed Ruggedized ST Fiber-to-RS422 Interface Converter

  • Field proven, highly reliable performance!
  • High quality manufacturing consistency maintained via established design documentation control.

Model 4042 ST Glass Fiber to Copper DB9 RS422 Interface Converter. 

 The Model 4042 is a high speed ruggedized ST Fiber to RS422 interface converter.  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: The converter provides an industrial solution for applications requiring a single point-to-point or a communications link over short and long distances.  

  • PC to PC Long Distance Communications
  • Factory Automation
  • Data Collection Devices
  • Barcode Readers
  • Time Clocks, Scales
  • Data Entry Terminals, ATM's
  • Serial Communications in Harsh Environments 

The Model 4042 is designed to operate from -40°C to 85°C.  The unit features ESD protection circuitry on the RS422 copper interface.  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 the DB9 connector.  Other features include user selectable fiber polarity, TX, RX and Power indicator LEDs.

FEATURES:

  • Model 4042 converts ST Duplex Fiber to Copper RS422 DB9 (F) port.
  • 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.
  • Provides full galvanic isolation (no metallic connection) between connected devices.
  • LED Status indicators display Fiber RX, TX activity and power indication.
  • Circuit boards conformal coated in accordance with IPC-CC 830 suing the type of UR Class B using HumiSeal A133 Urethane conformal coating.
  • The circuit board is fabricated to Class 2 standards.
