National Instruments PCIe-8432/4 Serial Interface Device
The PCIe-8432/4 is a 4-Port Serial Interface Device manufactured by National Instruments. This Serial Interface Device is an isolated, high-performance interface, which is ideal for port-to-port, high-speed communication with RS232 devices. This device is similar to the PCIe-8432/2 but has 4 ports instead of 2. The National Instruments PCIe-8432/4 Serial Interface Device has a PCI Express bus connector and does not have a supported power input. The only required accessory to use this device is an RS232 cable with DB-9 Female to DB-9 Male connections. The cable is available in 1 m, 2 m, or 4 m. The user should note that the maximum cable length for PCI Express Interfaces is 2,500 pF equivalent.
A few of the best features of the PCIe-8432/4 Serial Interface Device include multiprocessor support, high-performance DMA transfers, and multithreading. The NI PCIe-8432/4 device is compatible with both Windows and LabVIEW Real-Time operating systems. The PCIe-8432/4 has 15,000 V ESD protection, and 60 VDC continuous and 2000 V withstand port-to-port and port-to-PC isolation. The National Instruments PCIe-8432/4 Serial Interface Device has a continuous operating rated voltage of -25 V to +25 V. The maximum serial transfer rate of this Serial Interface Device is 1 Mbps.
The NI PCIe-8432/4 Serial Interface Device is solely meant for indoor use. The power requirement from the PCI Express channel is around 55 mA typical or 160 mA maximum for +12 VDC. For +3.3 VDC, the typical power requirement is 610 mA typical and 650 mA maximum.
