NEW - Quad isolated serial Communication, programmable RS-232/422/485 Ports
|
QMC mezzanine modules plug into a carrier card to interface connected I/O and provide a variety of signal processing functions. Acromag QMC520 modules offer four programmable, isolated serial ports for safe, reliable communication with a broad range of systems. A PCIe bus interface provides communication to the carrier and host computer.
Each port is isolated and individually programmed for RS-232, RS-422, or RS-485 communication to provide optimal flexibility and utility. Software-configuration helps you quickly set baud rates, character-sizes, stop bits, and parity.
For more efficient data processing, each serial port is equipped with 256-character FIFO buffers on the transmit and receive lines. These FIFO buffers minimize CPU interaction for improved system performance.
The data ports generate individually controlled transmit, receive, line status, data set, and flow control interrupts. All interrupts can be read from a single register.
The 16-bit timer/counter uses an internal 125MHz clock. This timer supports a single-shot mode for one-time events and a re-triggerable mode for periodic signals. The timer can also generate interrupts for timeout conditions.
QMC modules adhere to the VITA 93 standard for small form factor (SFF) mezzanine modules. Two high-performance 80-pin connectors provide separate field I/O and PCIe bus host interfaces. Modules can deploy on a variety of carrier card platforms including PCIe expansion cards, 3U/6U Eurocards such as VPX and CompactPCI, VNX+ SFF cards, and many other architectures. The rugged design is well-suited for use in laboratory, industrial, defense, and aerospace applications.
QMC modules have a much smaller footprint than PMC/XMC modules. Single-width QMC modules are only 26 x 78.25mm which facilitates mixing and matching of multiple functions on a single carrier card for high-density I/O solutions. They are ideal for computing systems with strict size, weight, power, and cost (SWAP-C) limitations.
An Intelligent Platform Management Interface (IPMI) facilitates system management. The QMC EEPROM holds module information and sensor data that is accessible by a smart carrier card with an IPMC controller over an I2C interface
