iConverter® RS232

Managed Serial RS-232 to Fibre Media Converter

The iConverter RS-232 is a managed Fibre to RS-232 converter that transmits serial protocol over fibre media.
The RS-232 media converters operate in pairs, extending serial distances over fibre up to 120km.

Available in single-mode dual fibre, multimode dual fibre or single-mode single-fibre transceivers, the Serial port interface is available with either a DB9 female connector or terminal block connector.

DTE or DCE mode is configured by DIP-switch on the front-panel of the module, eliminating the use of a null-modem cable to connect two serial devices of the same type.

Validation of the entire fibre segment is achieved by use of a built-in Fibre loopback.

The RS-232 plug-in module can be used unmanaged. In order to use the iConverter RS-232 in a managed application, simply install either the iConverter Management Module (NMM2) or Network Interface Device (NID) in the same chassis.

The management software can override the physical DIP-switch settings such as DTE or DCE selection, and fibre loopback test.

RS-232 parameters such as power, link, data activity status, module type, model, hardware and software revisions, serial numbers and a user-defined identifier can be monitored.

The RS-232 module is hot swappable, and can be mounted in a high-density 19 or 5-Module chassis with redundant AC and SC power supplies.
2-Module and 1-Module chassis with AC or DC power input are also available.

The iConverter RS-232 module is deployed in a star topology network in this example. In the upper left, the RS-232 modules are installed in an iConverter 19-Module Chassis to provide high-density distribution of fibre links from a 3rd party terminal server with DB9 copper ports.

At each end of the fibre links, an RS-232 module installed in an iConverter 1 module chassis provides the media conversion for connectivity to RS-232 equipment.
