Details

The Model 4149, desktop version, media converter is a very high speed ruggedized 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 4149 Fibre to RS Converter is designed to operate from -40°C to +85°C. It is a member of Electro Standards Laboratories' rugged community of fiber-to-copper media converters.

The Model 4149 features protection circuitry on all receivers and transmitters for both RS232 and RS485/422 interfaces. The unit's power input is protected from transients and features 3kVDC isolation to prevent system ground loops. It 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, dual DB9 power connectors (board only) for convenience in bused power applications, TX, RX and Power indicator LEDs.

This Fiber to RS converter is available as a board only, Model 4159, Cat. No. 304159, with front mounting threaded brackets for rack mounting in embedded applications. For applications that require an enclosure, it is available in a desk top package, Model 4149, Cat. No. 304149, with optional DIN rail mounting hardware. These Fiber Converters are ruggedized for commercial and military applications.
