PMC Modules
NEW!
PMC520 Octal Serial 232 Communication
These modules provide eight asynchronous serial communication ports from a single PMC carrier slot. Software-configuration helps you quickly set baud rates, character-sizes,stop bits,and parity. Signal support for RTS/CTS handshaking is also included. For more efficient data processing,each serial port is equipped with 64-character FIFO buffers on the transmit and receive lines. The data ports generate individually controlled transmit, receive,line status,and data set interrupts. A global interrupt source register provides interrupt status indication for all eight channels to speed up interrupt parsing.
With eight serial ports per module, the PMC520 provides a high-density solution to reduce costs and use fewer card slots.
