device<\/strong> designed for instrument control, industrial communication, automated test, laboratory systems, embedded device communication, and integration of legacy RS-232 equipment.\n<\/p>\n<p>\nInstalled in a compatible PCI Express slot, the PCIe-8430\/2 adds two independent RS-232 serial ports to a desktop, workstation, rackmount, or industrial computer.\n<\/p>\n<p>\nThe device is particularly useful in test and measurement systems that need reliable communication with instruments, controllers, sensors, barcode readers, programmable equipment, and other devices using conventional RS-232 serial interfaces.\n<\/p>\n<h3>Product Overview<\/h3>\n<p>\n\u0417\u0435\u043c\u043b\u044f <strong>National Instruments PCIe-8430\/2<\/strong> is designed for applications requiring multiple hardware serial interfaces directly integrated into a PCI Express host computer.\n<\/p>\n<p>\nA typical communication architecture is:\n<\/p>\n<p>\n<strong>Host Computer \u2192 PCI Express \u2192 PCIe-8430\/2 \u2192 RS-232 \u2192 Instrument \/ Controller \/ DUT<\/strong>\n<\/p>\n<p>\nWith two serial ports, one computer can communicate with multiple RS-232 devices within the same automated test or industrial control system.\n<\/p>\n<h3>Key Features<\/h3>\n<h4>Two RS-232 Serial Ports<\/h4>\n<p>\nThe PCIe-8430\/2 provides <strong>two RS-232 serial communication ports<\/strong>.\n<\/p>\n<p>\nThe two-port configuration is suitable for systems requiring simultaneous communication with multiple serial devices without installing several separate interface cards.\n<\/p>\n<h4>RS-232 Communication<\/h4>\n<p>\nThe PCIe-8430\/2 uses the widely adopted <strong>RS-232 serial communication standard<\/strong>.\n<\/p>\n<p>\nRS-232 remains common in:\n<\/p>\n<ul>\n<li>Test and measurement instruments<\/li>\n<li>Industrial controllers<\/li>\n<li>Laboratory equipment<\/li>\n<li>Embedded systems<\/li>\n<li>Barcode readers<\/li>\n<li>Motion controllers<\/li>\n<li>Programmable power equipment<\/li>\n<li>Legacy automation systems<\/li>\n<\/ul>\n<h4>PCI Express Host Interface<\/h4>\n<p>\nThe PCIe-8430\/2 installs into a compatible <strong>PCI Express expansion slot<\/strong>.\n<\/p>\n<p>\nThis allows modern computers with PCI Express expansion capability to communicate with equipment that still relies on RS-232.\n<\/p>\n<p>\nA typical configuration is:\n<\/p>\n<p>\n<strong>Industrial PC \u2192 PCIe-8430\/2 \u2192 RS-232 Cable \u2192 External

architecture is useful for automated test systems where several instruments or DUT interfaces must be controlled from one host computer.\n<\/p>\n<h4>Hardware-Based Serial Interface<\/h4>\n<p>\nThe PCIe-8430\/2 provides dedicated serial communication hardware rather than relying on a simple external USB-to-serial conversion architecture.\n<\/p>\n<p>\nAn internal PCI Express interface can be advantageous in fixed industrial, laboratory, and rackmount systems where the serial interfaces are intended to remain permanently installed.\n<\/p>\n<h4>Suitable for Instrument Control<\/h4>\n<p>\nRS-232 has historically been widely used for remote instrument communication.\n<\/p>\n<p>\nThe PCIe-8430\/2 can therefore be integrated with compatible:\n<\/p>\n<ul>\n<li>Power supplies<\/li>\n<li>Electronic loads<\/li>\n<li>\u041c\u0443\u043b\u044c\u0442\u0438\u043c\u0435\u0442\u0440\u044b<\/li>\n<li>Temperature controllers<\/li>\n<li>Motion controllers<\/li>\n<li>Environmental chambers<\/li>\n<li>Laboratory instruments<\/li>\n<li>Industrial controllers<\/li>\n<\/ul>\n<h4>Legacy Equipment Integration<\/h4>\n<p>\nMany industrial and laboratory devices remain operational for many years and continue to use RS-232 even when the host computer has been upgraded.\n<\/p>\n<p>\nThe PCIe-8430\/2 provides a practical way to retain these devices while migrating the host system to a computer with PCI Express expansion slots.\n<\/p>\n<h3>Technical

RS-232 communication capability to compatible computers.\n<\/p>\n<h4>How many serial ports does PCIe-8430\/2 have?<\/h4>\n<p>\nThe PCIe-8430\/2 provides <strong>two independent serial ports<\/strong>.\n<\/p>\n<h4>What serial standard does PCIe-8430\/2 support?<\/h4>\n<p>\nThe PCIe-8430\/2 is designed for <strong>RS-232 serial communication<\/strong>.\n<\/p>\n<h4>Is PCIe-8430\/2 a PCI or PCI Express card?<\/h4>\n<p>\nThe PCIe-8430\/2 uses a <strong>PCI Express<\/strong> host interface. It should not be confused with older conventional PCI serial interface cards.\n<\/p>\n<h4>Can PCIe-8430\/2 control test instruments?<\/h4>\n<p>\nYes. Instrument control is one of the primary applications for RS-232 interfaces. The connected instrument must provide a compatible RS-232 interface and communication protocol.\n<\/p>\n<h4>Can PCIe-8430\/2 communicate with two devices simultaneously?<\/h4>\n<p>\nYes. The two serial ports can be configured independently and used to communicate with two compatible RS-232 devices.\n<\/p>\n<h4>Can PCIe-8430\/2 be used with LabVIEW?<\/h4>\n<p>\nYes. The PCIe-8430\/2 can be integrated into compatible LabVIEW applications for serial instrument control, automated testing, data logging, and equipment communication.\n<\/p>\n<h4>Can PCIe-8430\/2 be used with NI-VISA?<\/h4>\n<p>\nYes. NI-VISA can be used in compatible software environments to configure and communicate with serial instruments through the PCIe-8430\/2.\n<\/p>\n<h4>Does PCIe-8430\/2 support RS-485?<\/h4>\n<p>\nThe PCIe-8430\/2 is intended for RS-232 communication. If the external equipment requires RS-485 or RS-422, select an interface specifically designed for that electrical standard.\n<\/p>\n<h4>What is the difference between PCIe-8430\/2 and PCIe-8430\/4?<\/h4>\n<p>\nBoth belong to the same RS-232 serial interface family. The primary difference is port count: the PCIe-8430\/2 provides two serial ports, while the PCIe-8430\/4 provides four.\n<\/p>\n<h4>Can PCIe-8430\/2 replace a USB-to-RS-232 adapter?<\/h4>\n<p>\nPotentially. The PCIe-8430\/2 provides an internal PCI Express serial interface and can be more appropriate for permanently installed automated test or industrial systems. Connector, software, and communication compatibility should be verified before replacement.\n<\/p>\n<h4>Why does my PCIe-8430\/2 communicate with some devices but not others?<\/h4>\n<p>\nCheck the baud rate, data bits, parity, stop bits, flow control, connector pinout, straight-through or null-modem cable configuration, termination character, and the command protocol required by the external device.\n<\/p>\n<h4>What cable should I use with PCIe-8430\/2?<\/h4>\n<p>\nThe required cable depends on the external device connector and pinout. Verify connector gender, DTE\/DCE configuration, straight-through or null-modem wiring, handshake signals, and cable length before selecting the cable.\n<\/p>\n<h4>Is PCIe-8430\/2 suitable for legacy equipment?<\/h4>\n<p>\nYes. It is particularly useful when a newer PCI Express computer must communicate with existing instruments or industrial devices that continue to use RS-232.\n<\/p>\n<h4>What should I check before purchasing PCIe-8430\/2?<\/h4>\n<p>\nVerify that the external equipment uses RS-232, determine the required number of ports, check connector and cable pinout, baud rate and flow-control requirements, confirm an available PCI Express slot, and verify operating system, driver, NI-VISA, LabVIEW, and existing application compatibility.\n<\/p>\n<h3>\u0417\u0430\u043a\u043b\u044e\u0447\u0435\u043d\u0438\u0435<\/h3>\n<p>\n\u0417\u0435\u043c\u043b\u044f <strong>NI PCIe-8430\/2 2-Port RS-232 Serial Interface Device<\/strong> provides two independent RS-232 ports through a PCI Express host interface.
