Point to point/Multi-drop Bus/Self-healing Ring Fiber Links
The RS-485/422 Fiber Optic Converter data series uses the most advanced digital technologies to provide excellent repeatable performance for today's data systems. It supports transmission of one bi-directional data channel over one multimode or single mode optical fiber. RS232, RS422 and RS485 (2 wire & 4 wire) standards are fully supported. The plug-and-play design ensures ease of installation with no electrical or optical adjustment needed. LED indicators are provided to show the operational status of the unit clearly.
The series is available in compact wall mount or 3U chassis card.
The RS-485/422 Series converter is equipped with a multiple interface circuit that can handle RS-485/422 serial interfaces and multi-mode or single- mode fiber. RS-485/422 converters are used to extend serial transmission distance up to 2 km (multi-mode fiber) or up to 20-100km (single- mode fiber).Auto Baud Rate Detection The RS-485/422 Series incorporates a method for automatically detecting the serial signal baud rate by hardware. This is an extremely convenient feature for the user. Even if a device's baud rate is changed, the signal will still be transmitted through the RS-485/422to fiber converter without any problem.
