PMC PMC520-64R

PMC Modules
Octal Serial 232
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
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
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.

PMC Modules
For more efficient data processing,each serial port is
equipped with 64-character FIFO buffers on the
transmit and receive lines.
With eight serial ports per module, the PMC520 provides a high-density solution to reduce costs and use fewer card slots.
