PMC520

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. Specifications RS232E Serial Ports Configuration: Independent,non-isolated serial ports with a common single return connection and configured as a DTE device. Data rate: Programmable up to 120K bits/second using internal baud rate generator. Max. cable length: 15 meters (50 feet) typical,limited to a cable capacitive load of 2500pF. Character size: 5 to 8 bits,software-programmable. Parity: Odd,even,or no parity;software-programmable. Stop bits: 1,1-1/2,or 2 bits;software-programmable. Data register buffers: Double buffered or 64-byte FIFO buffered,mode selectable. Interrupts: Receiver line status (overrun,parity,framing error, or break interrupt);received data available (FIFO level reached) or chara...
