Omnitron iConverter X21

Protel - iconverter x21

The iConverter X21 is a X.21 or RS-530 serial-to-fibre media converter, and is available as a compact, unmanaged standalone unit or a managed chassis plug-in module. The iConverter X21 supports several configuration modes to enable connections with a wide variety of X.21 and RS-530 devices.

The X21 supports demanding applications where security, and performance are critical. The X21 provides the reliability and connectivity features necessary for enterprise and military applications, including controlling radar installations from remote distances.

The X21 can auto-detect and configure itself to match the baud rate of the connected device up to 8.192Mbps. The X21 supports standard DCE-sourced timing and terminal timing.

The X21 also supports RS-530 DCE and DTE co-directional timing, Tx and Rx data, and two control lines. An adapter cable is included to accommodate different gender connectors.

The X21 features local loop-back configuration to facilitate quick link testing and installations.

The X21 supports both standard and CWDM Small Form Pluggable (SFP) transceivers, enabling adaptability to different fibre types, distances and wavelengths, providing maximum flexibility across a variety of network architectures and topologies.

The X21 also supports fixed-fibre multimode and single-mode dual fibre with ST, SC and LC connectors; and single-mode single-fibre with SC connectors.

The iConverter X21 is available as a compact, unmanaged standalone unit or as a chassis managed plug-in module. The hot-swappable plug-in module can be mounted in a 19 or 5-Module chassis with any combination of redundant AC and DC power supplies. It can also be mounted in a 2-Module AC or DC powered chassis, or in a 1-Module chassis with AC or DC power input.

The X21 standalone unit is available as a table top or wall mount unit. The table top model can be DIN-rail mounted using an optional DIN-rail mounting kit. Both the table top and the wall-mount models are DC powered and are available with an external AC to DC power adapter or a terminal connector for DC power.

The iConverter X21 plug-in module can be used in managed or unmanaged applications. Management provides remote configuration, monitoring and trap notification. Management of the X21 plug-in module 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 X21 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 local loopback test. Some of the real-time X21 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 X21 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

The iConverter X21 serial to fiber converter provides a secure and safe environment for controlling high security or hazardous environments by extending the distance between locations up to 120km over single-mode fiber.
