The iConverter X21 is a X.21 or RS-530 serial-to-fiber 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 supports fixed-fiber multimode and single-mode dual fiber with ST, SC and LC connectors; and single-mode single-fiber with SC connectors.

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

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.

iConverter X21 media converters are available as compact, unmanaged standalone units, or chassis plug-in modules that can be managed with a Management Module (NMM2) or Network Interface Device (NID) installed in the chassis. The management module provides access to all the advanced features on the module.

The X21 standalone models are available with an external AC to DC power adapter or with a 2-pin terminal connector for direct connection to DC power. The standalone module can be DIN-Rail mounted using the optional DIN-Rail mounting bracket (8250-0) or mounting clips (8251-0).

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.
