Industry Pack Modules Industry Pack Modules IP500A Serial 232 Communication 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 Thee IP500A provides four 232 communication ports with FIFO buffers for reliable data transfer across serial communication lines. support for modem control is also included. Specifications Ordering Information For more efficient data processing, each serial port is equipped with 16-character FIFO buffers on the RS232E Serial Ports Industry Pack Modules Configuration: Independent, non-isolated serial ports with a transmit and receive lines. IP500A common single return connection and configured as a Four RS232E serial ports. The data ports generate individually controlled transmit, DTE device. Acromag offers a wide selection of Industry Pack Carrier Cards. receive, line status, and data set interrupts.
