Electro Standards: Fast Fiber to Serial Converter
Fiber to serial converter.
Cranston, RI — Electro Standards Laboratories (ESL) has introduced its new Model 4149 high-speed ruggedized Fiber-to-RS485/422/232 interface converter. Typical operating speeds are 1.5 Mbps for RS232 to fiber conversion and 20 Mbps for RS485/422 to copper conversion.

The converter is designed to operate from -40 to +85°C and provides protection circuitry on all receivers and transmitters for both RS232 and RS485/422 interfaces. The unit's power input is protected from transients and has 3kVDC isolation to prevent system ground loops. M4149 can be powered from a wide input range of 9 to 36VDC, with models also available for other voltage ranges such as 4.5 to 9VDC and 18 to 72VDC.

Other features include user-selectable fiber polarity, dual DB9 power connectors (board only) for convenience in bused power applications, TX, RX and power indicator LEDs. The converter is available as a board only, Model 4159, with front mounting threaded brackets for rack mounting in embedded applications. This unit is also available in a desktop package with DIN rail mounting hardware for applications that require an enclosure.
