PMC Modules PMC Modules NEW! Not Actual Photo PMC521 (available 4th Qtr 2004) Octal Serial 422/485 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. With eight serial ports per module, the PMC521 provides a high-density solution to reduce costs and use fewer card slots. For more efficient data processing, each serial port is Specifications Ordering Information equipped with 64-character FIFO buffers on the transmit and receive lines. RS422B Serial Ports PMC Modules Configuration: Independent, non-isolated serial ports with a PMC521-64 The data ports generate individually controlled transmit, common single return connection. Eight RS422B serial ports, front I/O connector receive, line status, data set, and flow control interrupts. Data rate: 250K bits/second, maximum. PMC521-64E A global interrupt source register provides interrupt Max. cable length: 1200 meters (4000 feet), typical. Same as PMC521-64 plus extended temperature range. status indication for all eight channels to speed up Character size: 5 to 8 bits, software-programmable. PMC521-64R interrupt parsing. Same as PMC521-64 except with rear I/O connector Parity: Odd, even, or no parity; software-programmable. PMC521-64RE Stop bits: 1, 1-1/2, or 2 bits; software-programmable. Features Same as PMC521-64R plus extended temperature range Data register buffers: Double buffered or 64-byte FIFO ■Eight asynchronous, full duplex RS422B buffered, mode selectable.
