RS-485 Self-healing Ring Fiber Optic Converter

The Rs-485 Self-healing Ring Fiber Optic Transmission series products provide an optical self-healing ring network for RS-485/422 data interfaces over two multi mode or single mode optical fibers. The system offers maximum reliability as it can recover simultaneous faults or failures in two different locations and has contact closure outputs on each module to clearly indicate any fault location. The self-healing ring consists of two opposing data paths, ring A and ring B. Under normal operation only the primary path (ring A) is used for data transfer. If a fault is detected, the data is transferred to the secondary path (ring B) without interruption to the communications network.
The series is available in wall mount, DIN rail or 3U chassis card.

HFD-FO-485 RS-485/422 Fiber Optic Converter

The HFD 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 singlemode optical fiber. 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 DetectionThe 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.

Product Features of the RS485/422 to Fiber Converter:
Supports RS422 and RS485
Multimode and singlemode solutions
Switchable 120Ω Termination and biasing
LED indicators provide quick diagnosis of all important system parameters
Up to 14 units in a 3U chassis
Compact and 3U chassis card configuration, Dual power supplies
