Product short description:
- 8 asynchronous full duplex EIA/TIA-422B serial ports (supports EIA-485)
- 64-byte FIFO buffers
- Interrupt support
- Programmable baud rate (up to 1.8432Mbps)
These modules provide eight asynchronous serial communication ports from a single PMC Socket.
PMC521: PMC Serial Communication, 422/485 Octal Module Description
These modules provide eight asynchronous serial communication ports from a single PMC Socket. Software-configuration helps you quickly set baud rates, character-sizes, stop bits, and parity.
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, data set, and flow control interrupts. A global interrupt source register provides interrupt status indication for all eight channels to speed up interrupt parsing.
