Product short description:
  • 8 asynchronous full duplex EIA/TIA-422B serial ports (supports EIA-485)
  • 64-byte FIFO buffers
  • Interrupt support
  • Programmable baud rate (up to 1.8432Mbps)
Kindly go to setting page and check the option "Place them manually"

These modules provide eight asynchronous serial communication ports from a single PMC Socket. 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 64-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. A global interrupt source register provides interrupt status indication for all eight channels to speed up interrupt parsing.

Specifications

RS422B Serial Ports

Configuration: Independent, non-isolated serial ports with a common single return connection.
Data rate: 20MB /second, maximum. Standard crystal limits data rate to 1.8432Mbps.
Max. cable length: 1200 meters (4000 feet), typical.
Character size: 5 to 8 bits, software-programmable.
Parity: Odd, even, or no parity; software-programmable.
Stop bits: 1, 1-1/2, or 2 bits; software-programmable.
Data register buffers: Double buffered or 64-byte FIFO buffered, mode selectable.
Interrupts: Receiver line status (overrun, parity, framing error, or break interrupt); receive/transmit FIFO level reached or character time-out; Xon/Xoff or special character detected.

Environmental

Operating temperature: 0 to 70°C (PMC521-64) or -40 to 85°C (PMC521-64E).

  • Description

    Screw terminal panels simplify field signal wiring. A cable connector provides a clean interface to the I/O board or module.

    Many termination panels have a compact footprint and mount neatly on a DIN rail strip. Other panels are designed for mounting directly onto a standard 19-inch computer rack.

    All of Acromag’s I/O boards have a corresponding termination panel. This convenience saves you the time and hassle of finding a compatible panel or crafting your own.

    For more information see the module’s user manual.
