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. 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. Features ■ Eight RS232E ports ■ 64-byte transmit FIFO buffers 64-byte receive FIFO buffers ■ Programmable baud rate (up to 120Kbps) ■ Individual handshake lines (RTS,CTS) on each channel ■ Line-break and false start-bit detection ■ Industry-standard software-compatible 16C550 configuration registers Benefits ■ High-density design lowers per-port costs and saves PMC carrier card slots for other functions. ■ 64-byte FIFO buffers minimize CPU interaction for improved system performance. ■ Each serial channel provides handshake support to simplify interfacing with modems.
