HFD-FO-232 Self-healing Ring(DSHR) Multi-drop Bus Fiber Optic Converter

The RS-232 Dual Self-healing Ring Transmission series products provide an optical self-healing ring network for RS232 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.

Product Features
Supports RS232 data, Dual redundant power supply
Multimode and singlemode solutions
Contact closure alarm outputs per station
Single or dual fibre configurations
DIN rail and 3U chassis card

DIN Rail RS-232 Fiber Optic Modem(Multi-drop Bus Link)

The DIN Rail RS- 232 Multi-Drop Bus Fiber Optic Modem series products provide an optical bus network for RS-232 data interfaces over a pair of multi mode or single mode optical fibers. The Terminal module units operate as the end or terminal points and provide an electrical connection and a two fibre optical connection. The Repeater module units act as in-line repeater stations and provide a single electrical connection and two optical connections, one upstream and one downstream. This series is available in either wall mount, DIN rail or 3U chassis card configurations.

Product Features
Multi protocol data interface
Switchable termination and biasing
Multimode and singlemode
Wall mount, DIN and 3U chassis card

DIN Rail RS-232 Fiber Optic Converter

The RS-232 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 multi mode or single mode optical fiber. RS232 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 DIN Rail compact wall mount or 3U chassis card.

The RS-232 Series fiber optic converter is equipped with a multiple interface circuit that can handle RS-232 serial interfaces and multi-mode or single- mode fiber. RS-232 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-232 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-232 to fiber converter without any problem.

Product Features:
Supports RS232, Dual redundant power supply
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
