IP502: Serial Communication, 485 Half-Duplex Industry Pack Modules

IP502: Serial Communication, 485 Half-Duplex Industry Pack Modules Description

These modules provide an asynchronous serial communication interface for your system. The IP502 has four asynchronous, half-duplex RS485 serial ports. It provides a cost-efficient interface to RS485 multi-driver networks which support up to 32 nodes. However, for full handshaking support, use the full duplex IP501.

Software-configuration quickly sets the baud rate, character-size, stop bits, and parity.

For more efficient data processing, each serial port is equipped with 16-character FIFO buffers on the transmit and receive lines.

Update to AcroPack mezzanine modules into your host system, they maintain the same functionality and memory map of Acromag’s existing Industry Pack (IP) modules. Learn More >
