National Instruments part number 780592-01 is an identifying part number for the PCIe-8431/8 a Serial Interface Device with 8 Ports. The NI 780592-01 features a 68-pin VHDCI I/O connector and includes a cable that connects the onboard 68-pin VHDCI port to 8 male DSUB-9 serial ports. The board measures 4.38 × 6.9 inches and weighs approximately 90 grams, allowing for easy deployment in any standard PC with an available PCIe or PCI Express slot. This serial interface device does not require additional external power, as it draws current from the PCIe channel. Under normal operating conditions, it requires 200 mA at +3.3 VDC and 190 mA at +12 VDC. In some cases, the device may draw up to 750 mA and 220 mA for the respective voltage power.
This device offers flexible baud rates, both standard and nonstandard, ranging from 57 baud/sec to 1 Mb/s, with an accuracy of 0.01% for standard rates and 1% for nonstandard rates. It supports a maximum baud rate of 3000 kbits/s. This model is compatible with various software infrastructures, including the LabVIEW real-time operating system and Microsoft Windows. It suits a wide range of applications by allowing users to choose between 4-wire transceiver mode and 2-wire transceiver mode, enabling full-duplex or half-duplex communication.
The NI 780592-01 serial Interface Device weighs 0.20 lb and measures 4.38 x 6.9 inches. It has recommended operating temperature ranges from 0 to 55 °C and storage temperature ranges from –20 to 70 °C. The device supports non-condensing humidity levels of 10 to 90% for operation and 5 to 95% for storage. The PCIe-8431/8 is compatible with RS-485 and RS-232 cables, with maximum lengths of 30 m (limited by EMC/surge) and 2500 pF (TIA-EIA-232-F 2.1.4), respectively. It meets safety standards for electrical instruments, including IEC-60068-2-1 and IEC-60068-2-2.
