    • Storage Temperature-40°C to +85°C.
    • Relative Humidity0–80% non-condensing (operating), 0–95% non-condensing (storage).
    • Altitude: Up to 10,000 ft during operation.
  • Physical Dimensions:
    • Length: 149 mm.
    • Width: 74 mm.
    • Compact form factor suitable for space-constrained installations.

FUNCTIONAL FEATURES

  • Multi-Protocol Flexibility: Software-configurable transceivers eliminate the need for physical protocol-specific hardware, reducing costs and simplifying upgrades.
  • High Data Throughput: Deep FIFO buffers and independent channels enable simultaneous handling of multiple high-speed data streams without loss or delay.
  • Reliability: Designed for continuous operation in harsh environments, with robust components and wide temperature tolerance.
  • Scalability: PMC form factor allows easy integration into larger systems, supporting up to four cards per host for expanded channel capacity.
  • Legacy Support: Compatibility with RS-232, RS-422, and other legacy protocols ensures seamless connectivity with older industrial equipment.

APPLICATION SCENARIOS

  • Industrial Automation:
    • Used in CNC machines, robotic controllers, and factory automation systems to manage real-time communication between PLCs, sensors, and actuators.
  • Data Acquisition & Monitoring:
    • Powers SCADA systems, environmental monitoring networks, and energy grid management by collecting and transmitting data from remote devices.
  • Telecommunications:
    • Integral to network routers, switches, and base station controllers, providing high-speed serial links for backhaul and access networks.
  • Transportation:
    • Supports railway signaling, traffic management, and fleet tracking systems, ensuring reliable communication in mission-critical environments.
  • Military & Aerospace:
    • Deployed in avionics, radar, and satellite communication systems, where rugged design and multi-protocol support are essential.
