The Acromag QMC520 is a rugged, compact VITA 93 Isolated Serial Communication Module. Designed to provide four isolated, programmable serial ports for reliable and secure communication across diverse embedded systems. Supporting RS-232, RS-422, and RS-485 protocols, each port is fully isolated. In addition, it is independently configurable to ensure safe, interference-free operation in demanding environments.
Ideal for defence, aerospace, industrial, and lab-based applications. Firstly, the QMC520 offers seamless integration via a PCIe bus interface, connecting through a QMC-compatible carrier card. Each serial port is equipped with 256-byte FIFO buffers on both transmit and receive lines. Which optimises throughput and reduces CPU load. Therefore, enabling efficient, high-speed data transfer up to 20Mbps.
The QMC520 has a 16550-compatible register set. It also has programmable interrupt generation for transmit, receive, line status, and flow control. This allows for advanced control of serial communication. A built-in 16-bit timer/counter uses a 125MHz internal clock. It supports single-shot and periodic signal modes. This is great for time-sensitive tasks and event tracking.
Built to the VITA 93 small form factor (SFF) standard. Secondly, the QMC520 measures just 26 x 78.25mm. Therefore, making it perfect for high-density I/O configurations where SWaP-C constraints are a concern. The design includes support for conduction cooling and operates across extended temperature ranges. An onboard EEPROM supports Intelligent Platform Management Interface (IPMI) for efficient module management through I²C.
