Consult factory for long-term availability.

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 >

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

  • Four asynchronous, half-duplex EIA-485 serial ports
  • 16-byte FIFO buffers
  • Programmable baud rate (up to 512Kbps) (Consult factory for custom rates up to 1M bps)
  • Individually controlled interrupts (unique vectors for each port)
  • Line-break and false start-bit detection
  • Industry-standard 16C550 family UART includes software-compatible 16C450 mode
  • 0 to 70°C
  • Failsafe receivers guarantee a high output state when the inputs are left open or floating.
  • Internal diagnostics help detect communication faults.
  • 16-byte FIFO buffers minimize CPU interaction for improved system performance.
