IP500A:
Serial Communication, 232
• Four asynchronous EIA/TIA-232E serial ports
• 16-byte FIFO buffers
• Interrupt support
• Programmable baud rate (up to 128Kbps)
These modules provide asynchronous serial and parallel communication interfaces for your system. Software-configuration helps you quickly set baud rates, character-sizes, stop bits, and parity. Full signal support for modem control is also included.
For more efficient data processing, each serial port is equipped with 16-character FIFO buffers on the transmit and receive lines.
The data ports generate individually controlled transmit, receive, line status, and data set interrupts. Since unique interrupt vectors may be assigned to each port, it is easy for you to identify and locate the interrupt source. Also, a priority shifting scheme prevents continuous interrupts from one port from blocking interrupts from another.
The IP500A is a drop-in replacement for the IP500, please see the known differences document below for more information.
