Quad Port Serial Communication Module AP512

The AP512 Series is an AcroPack® Module that provides a four isolated and full duplex RS422b (supports RS485) Serial Ports from a single AcroPack Carrier slot offering a high density solution. It has a PCIe Bus Interface with extended temperature range.

Ideally used in Automation, Defence, Aerospace and Research Labs.

The Acromag AP512 Series is a Quad Port Serial Communication Module and enables efficient data processing through the four RS422b Serial ports.

Firstly, the AP512 Series is based on the Acromag AcroPack® product line, which has a PCIe interface format. AcroPack® offers products in a compact size, at a low cost with the same functionality and memory map of existing Industry Pack Modules in a rugged form factor. Also they are RoHS compliant.

Secondly, to conduct more efficient data processing, each serial port has a 256-character FIFO buffers on the transmit and receive lines. The data ports generate individually controlled transmit, receive, line status and data set interrupts. All interrupts can be read from a single register.

Finally, the AP512 modules are 70mm long and only 19.05mm longer than a full length mini PCIe card. It contains a down facing connector which internally routes I/O signals through the carrier card to secure field connectors. Therefore, eliminating loose cables and increasing reliability.

Features of Quad Port Serial Communication Module AP512 includes:

  • Four asynchronous, full duplex RS422B serial ports (supports RS485)
  • Ports are isolated to 250V from digital and 100V from each other
  • 256-byte transmit FIFO buffers, 256-byte receive FIFO buffers
  • As well as programmable baud rate (up to 16Mbps)
  • Line-break and false start-bit detection
  • Failsafe receivers
  • 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
