Industry Pack Modules Industry Pack Modules IP521 Octal Serial 422/485 Communication These modules provide eight asynchronous serial communication ports from a single IP carrier slot. Software-configuration helps you quickly set baud rates, character-sizes, stop bits, and parity. With eight serial ports per module, the IP521 provides a high-density solution to reduce costs and use fewer card slots. For more efficient data processing, each serial port is Specifications Ordering Information equipped with 64-character FIFO buffers on the transmit and receive lines.
