Omnitron iConverter RS 422 / 485

iConverter RS-422/485The iConverter RS422/485 is a managed serial RS-422 and RS-485 to fibre converter that transmits serial protocol over fibre media. The RS422/485 media converters operate in pairs, extending serial distances over fibre up to 120km, which improves noise immunity from electrical and magnetic interference.

The RS422/485 is available with a single-mode dual fibre, multimode dual fibre or single-mode single-fibre 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 921,600 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 Fibre Loopback DIP-switch provides easy validation of the entire fibre segment without interrupting fibre operations.

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

iConverter RS422/485 modules are hot-swappable and can be mounted in a 19-Module (2U high) or 5-Module (1U high) rack-mountable chassis (19-inch or 23-inch) with any combination of redundant AC, 24VDC or 48VDC power supplies. They can also be mounted in a 2-Module AC or 18 to 60VDC powered chassis, or in a 1-Module AC or DC powered chassis.

  • Commercial (0 to 50°C) and wide (-40 to 60°C) temperature ranges
  • Lifetime Warranty and free 24/7 Technical Support

Management

The iConverter RS422/485 can be used in managed or unmanaged applications. Management provides remote configuration, monitoring and trap notification. Management is accomplished by installing an iConverter Management Module (NMM2) or Network Interface Device (NID) in the same chassis.

The Management Module can be accessed via SNMP, Telnet, and serial port. The RS422/485 can be managed with Omnitron’s intuitive, graphic-oriented NetOutlook SNMP Management Software or third party SNMP management software. Management via the Telnet and the serial interfaces have an easy-to-use, menu-driven interface.

The management software can override the physical DIPswitch settings such as DTE or DCE selection and Fibre Loopback test. Some of the real-time RS422/485 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 iConverter RS422/485 supports SNMP trap notification for the monitoring and notification of different network events. Specific events that generate traps include link-up and linkdown. Trap monitoring of specific events can be selectively enabled or disabled by the network management software.

Application Example

In this application example, iConverter RS422/485 modules are deployed in a bookend configuration to enable serial network distance extension over fibre. iConverter RS422/485 modules are installed at each end of the fibre 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.
