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 character time-out;transmitter
(FIFO level reached);or modem status (CTS).

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.
