The RI10 IP-to-Sync Controllers are a pair of 19-inch rack-mountable devices designed to transfer synchronous serial data over Ethernet (TCP/IP). These controllers enable the secure transfer of encrypted bulk data over IP across extended distances, leveraging existing high-performance COMSEC devices. Additionally, the RI10 functions as a split-site controller, providing comprehensive configuration, control, and status capabilities.

The RI10 efficiently breaks continuous serial data streams into fixed-size packets, adds IP framing, and transmits the data over a packet-switched Ethernet network, such as Defence LAN/WAN, to remote transmission or reception sites. In reverse, the received IP data is de-encapsulated and synchronously clocked into data encryption equipment, like NATO KIV-7M and KG-84 encryptors.

The RI10 comes in two variants: the DCE variant, positioned between the COMSEC device and the Wide Area Network (WAN), and the DTE variant, which operates as a Data Terminal Equipment device on the radio equipment side. Notably, when using the RM10 HF Wideband Modem, the RI10 DTE variant is unnecessary due to the RM10's embedded DATA LAN/WAN port.

Ideal for installation on naval and maritime platforms, as well as NATO shore stations requiring split-site operations (e.g., BRASS/BRE1TA and BRIPES), the RI10 is part of the RapidM Family 10 Suite. This suite includes the RM10, RC10, RB10, and RS10 products, all sharing a common hardware platform, ensuring a long (20-year) product and spare availability period.
