Product Description

The PXI-8430 series consists of high-performance serial interfaces for communication with RS232 devices. Unlike standard PC serial ports, these modules are designed specifically for intensive automation and test applications, offering superior throughput and reduced CPU utilization.

Product Parameters

The PXI-8430 is available in different port counts (typically 2, 4, or 8 ports). Below are the core technical parameters:

Product Advantages

• High-Speed Performance: Supports non-standard baud rates and high speeds up to 1 Mbps with 0.01% accuracy.

• DMA Transfers: Uses Direct Memory Access (DMA) to transfer data between the module and memory, significantly reducing the CPU load compared to standard interrupt-based serial ports.

• Hyper-threading Support: Designed to work efficiently in multi-core and multi-threaded environments.

• Isolation (Optional): Models with isolation protect your PXI system and other connected devices from ground loops and high-voltage spikes in industrial environments.

• Ease of Integration: Fully compatible with NI-VISA, making it easy to program using LabVIEW, C++, and .NET.

Key Considerations

• Cable Length: While the PXI-8430 supports high speeds, RS232 cable length is generally limited. For 1 Mbps speeds, ensure you are using high-quality, shielded cables and keeping lengths short.

• Power Consumption: Ensure your PXI chassis has sufficient cooling and power headroom, especially if using multiple 8-port modules.

• Driver Compatibility: Always install the NI-Serial driver before inserting the hardware into the PXI chassis to ensure the OS recognizes the device correctly.

Product Applications

The PXI-8430 is a “workhorse” for any system requiring reliable serial communication:

1. Automated Test Equipment (ATE): Controlling programmable power supplies, DMMs, or older laboratory instruments that use RS232.

2. Industrial Automation: Interfacing with PLCs, barcode scanners, and motor controllers on a factory floor.

3. Data Acquisition: Collecting data from environmental sensors or GPS modules.

4. Legacy System Integration: Connecting modern PXI-based control systems to older industrial machinery.
