AP522: Octal Serial RS422/485 Communication Module Description

The AP522 octal serial RS422/485 communication modules provide eight asynchronous serial communication ports from a single AP carrier slot for a high-density solution. Software-configuration helps you quickly set baud rates, character-sizes, stop bits, and parity.

For more efficient data processing, each serial port is equipped with 256-character FIFO buffers on the transmit and receive lines.

The data ports generate individually controlled transmit, receive, line status, data set, and flow control interrupts. All interrupts can be read from a single register.

Designed for COTS applications these octal serial RS422/485 mezzanine modules deliver high-density, high-reliability, and high-performance at a low cost.

The AcroPack® product line updates our popular Industry Pack I/O modules with a PCIe interface format. This tech-refresh design offers a compact size, low-cost I/O, the same functionality and memory map of the existing Industry Pack modules and a rugged form factor.

The AP522 series modules are 70mm long, this is 19.05mm longer than the full length mini PCIe card at 50.95mm. The board’s width is the same as mPCIe board of 30mm and they use the same mPCIe standard board hold down standoff and screw keep out areas.

A down facing 100 pin Samtec connector will mate with the carrier card. Fifty of these signals are available as field I/O signals. Pin spacing and signal assignments will allow for 100V of signal to signal isolation.

The AP522 series maintains the same functionality and memory map of the existing Industry Pack modules providing a smooth transition to the AcroPack I/O modules.

AcroPack modules are RoHS compliant and ideal for military, defense, automation, aerospace, scientific, and development labs industries.

AP522: Octal Serial RS422/485 Communication Module Benefits & Features

  • Eight asynchronous, full duplex RS422B serial ports (supports RS485)
  • 256-byte transmit FIFO buffers, 256-byte receive FIFO buffers
  • Programmable baud rate (up to 20Mbps)
  • Individual handshake lines (RTS, CTS) on each channel
  • Line-break and false start-bit detection
  • Failsafe receivers
  • Built-in termination and bias resistors (Consult factory for no termination)
  • 16550 compatible register set
  • High-density design lowers per-port costs and saves IP carrier card slots for other functions.
  • 256-byte FIFO buffers minimize CPU interaction for improved system performance.
  • Extended temperatures deliver dependable operation in extreme conditions.
