National Instruments PCI-8431/8 Serial Interface Device

This Serial Interface Device (RS485/RS422) is a PCI with 8 ports. The PCI-8431/8 (Part Number: 779148-01) offers AT serial equipment with up to 2000 V of optical detachment for protected, solid communication in modern conditions. Disconnected ports give solid communication in circumstances including ground circles from various ground levels or high basic mode voltage actuated on the lines in loud situations. The disengagement between every communication port on the PCI-8431/8 device and the host PC guarantees the sheltered task of the PC and the gadgets associated with different ports on a similar board amid unplanned high voltages or line floods on communication lines. The device has a power requirement of 1.3 A typical and 1.9 A maximum at +5 VDC.

The NI PCI-8431/8 RS485 Serial Interface Device bolsters four equipment handset control modes, including a propelled 2-wire restraint mode that expels the weight of handset control from the user’s application. Users can utilize equipment handset control to empower and debilitate their transmitters and recipients with the goal that they work on various bus topologies. With LabVIEW, a simple to-utilize graphical improvement condition, the user can obtain information from a large number of various instruments, including serial gadgets, IEEE 488.2 gadgets, VXI gadgets, programmable rationale controllers, and module DAQ boards. After the user has gained the information, they can change it over into significant outcomes by utilizing the intense information examination schedules in LabVIEW. LabVIEW additionally accompanies several instrument drivers, which drastically decreases the user’s product advancement time since the user does not need to program the low-level control of each instrument. The device is equipped with a 68-pin SCSI I/O connector. It has a maximum baud rate of 3000 kbits per second. It has a FIFO size of 128 bytes.

The NI device weighs 85 g, and measures 4.2 x 5.7 in. in physical dimensions. It has recommended operating and storage temperature ranges of 0 to 55 °C and –20 to 70 °C respectively, operating and storage humidity ranges of 10 to 90% and 5 to 95% respectively.

PCI-8431/8 Mature Status has been announced by National Instruments, but will still be available for purchase and repairs by Apex Waves.
