The RC8X4 Quad ARQ Server & IP Controller is an advanced stand-alone hardware platform designed specifically for maritime and long-range (BLOS) communications. It houses four independent automatic repeat request (ARQ) and vocoder functions, fully compliant with the STANAG 5066 Edition 3 specification. This makes it an ideal choice for strategic and maritime data communications, especially where space, size, weight, power, and cost are critical factors.

The RC8X4 shares significant commonality with the RC8, allowing for easy integration into both land-based and ship-borne 19-inch rack setups, occupying just a single 1U slot.

This platform seamlessly interfaces with RM8 or RM8X4 Software-Defined Modems (SDMs) and external link encryptors, ensuring reliable data communication over HF links, even in the most challenging channel conditions. The RC8X4 supports various services such as email, messaging, ACP 127, and IP data transfer.

In its most basic configuration, the RC8X4 offers four 'IP-to-sync' data converter functions and hosts four STANAG 5066 ARQ servers for error-free data transfer. The embedded STANAG 5066 IP and COSS Clients enhance its versatility as it can be operated in both fixed frequency and multi-frequency networks, utilising ALE 2G or 3G (Fast Link Setup) channel access functions for efficient link establishment and maintenance.

The RC8X4 is further equipped with serial and Ethernet interfaces for data and external GPS, along with two audio interfaces per function. This robust platform allows various external RapidM or third-party clients to connect with the 5066 servers using the RAW SIS protocol, facilitating concurrent access to the radio line, ARQ server, encryptor (COMSEC), modem, and transceiver.

Backed by RapidM’s unwavering commitment to long-term product availability and support, the RC8X4 guarantees optimal performance and functionality in demanding operational environments.
