TELEMETRIX 500 IP TDC MULTIPLEXER/DEMULTIPLEXER(T500MX)
OVERVIEW
 The RT Logic Telemetrix® 500 IP TDC Multiplexer/Demultiplexer Protocol Translator (T500MX) deterministically transports serial telemetry and associated IRIG between locations linked by commercial IP-based networks, while maintaining very low latency and rigid Time-Data Correlation (TDC), and preserving signal integrity. The T500MX supports aggregate data rates up to 1 Gbps, leveraging the inherent switching power of IP networks to provide reliable and robust data delivery from the source to multiple destinations.

APPLICATION
 Telemetry collection and processing centers, control centers, ground stations, test sites, and payload operations facilities are migrating from expensive dedicated serial interconnections to commercially available IP networks. Multiple telemetry streams often need to be transmitted from one point to another over large distances while maintaining their time-data relationship.

The T500MX encapsulates the network, making it transparent to the real-time delivery of time correlated signals. The T500MX translates between custom serial signaling used by legacy and modern telemetry equipment, and the standards-based IP network protocol. Conversion back to the original serial signaling at the destination with high-fidelity allows the T500MX to be a drop-in replacement for existing serial transport mechanisms. The T500MX offers options to support CCSDS SLE, AFSCN Interoperability protocols and TENA.

Serial telemetry and IRIG signals are transported via IP protocol between a source (local or remote) T500MX, and one or more destination (local or remote) T500MX units. Variable network latency is factored out by dynamic rate buffering and a deterministic timing scheme that utilizes an adaptive high-rate clock to control stream-to-stream skew. The timing approach factors source input jitter out of the destination streams and produces accurate serial output at each destination.

The T500MX efficiently performs conversion to and from IP packets, relying on Field-Programmable Gate Array (FPGA) technology running software-defined algorithms to provide speed and configurability. Telemetrix software is included allowing dynamic and/or static configuration and monitoring of the distribution network.

THE T500MX
DIFFERENCE


MODULAR, DIGITAL DESIGN
 The T500MX is a server-class PC running a real-time Linux operating system with hot-swappable disk drives, dual hot-swappable power supplies, Intel Xeon CPU, multiple Gb Ethernet ports, and RT Logic analog/digital processor cards. It is available in 1U, 2U, or 5U configurations, and mounts in a 19-inch rack. Multiple I/O options are available including TTL, RS-422, ECL, LVPECL, and LVDS signal lines to support a wide variety of signal interfaces and data rates. Numbers and types of I/O ports can be selected to provide a cost-efficient transport solution. The modular design of the T500MX and the Telemetrix software architecture permits easy tailoring of a standard T500MX configuration to meet customer specific requirements. The system is compatible with most third-party systems, as well as all of RT Logic’s other offerings, such as the T70/70XL and T720HDR.
