Description


The iConverter RS422/485 is a managed serial RS-422 and RS-485 to fiber converter that transmits serial protocol over fiber media. The RS422/485 media converters operate in pairs, extending serial distances over fiber up to 120km.

The RS422/485 is available with a single-mode dual fiber, multimode dual fiber or single-mode single-fiber transceiver. The serial port interface is available with either a DB-9 female connector or terminal block connector for field wiring.

The RS422/485 automatically detects the data rate of connected Full-Duplex serial device, ranging from 110 bps to 1,024,000 bps. It also automatically adjusts to changes in the connected device’s Full-Duplex data rate during operation without reconfiguration or interruption of service.

Half-Duplex RS-485 and Full-Duplex RS-485 (sometimes referred to as Multipoint RS-422) operations are supported via a configurable baud rate DIP-switch to match the master/ slave communication timing.

Connection to DTE or DCE devices are configured by an easily accessible DIP-switch on the front-panel. This feature eliminates the need to use a specific serial cable for each type of device.

A built-in remote Fiber Loopback DIP-switch provides easy validation of the entire fiber segment without interrupting fiber operations.

Integrated configurable terminators support RS-422 and RS-485 operations, allowing the unit to be deployed at any node in the serial line.

The RS422 plug-in module can be used in managed or unmanaged applications. Management is accomplished by installing an iConverter Management Module (NMM2) or Network Interface Device (NID) in the same chassis. The management module provides access to all the advanced features available on the module.

The management software can override the physical DIP-switch settings such as DTE or DCE selection and Fiber Loopback test. Some of the real-time RS422 parameters that can be monitored include power, link, data activity status, module type and model, hardware and software revisions, serial numbers and a user-defined identifier.

The hot-swappable plug-in module can be mounted in a high-density 19 or 5-Module chassis with redundant AC and DC power supplies. It can also be mounted in a 2-Module or in a 1-Module chassis with AC or DC power input.





Examples


In this application example, iConverter RS422/485 modules are deployed in a bookend configuration to enable serial network distance extension over fiber. iConverter RS422/485 modules are installed at each end of the fiber link and provide media conversion for connectivity between a serial host/controller and multi-drop serial devices.

The RS-422 or RS-485 serial equipment can be industrial or manufacturing equipment, casino games, or utility SCADA equipment.
