National Instruments 779539-01 PXI Serial Interface Module
The 779539-01 Serial Interface Module is a component of the PXI‑8433/4 Model series, designed by National Instruments for industrial applications requiring high-speed, isolated communication with RS485 and RS422 devices. With a 2000 V withstand (Vrms/5 s) and port-to-port isolation up to 60 VDC continuous (CAT I), this module guarantees safe data transfer even in harsh settings. Its easy integration into a variety of systems is made possible by its compatibility with Windows and LabVIEW Real-Time OSs.
Because it has a fast DMA interface, the 779539-01 requires less CPU overhead while transferring data, which improves system performance. It ensures seamless data flow even under high loads thanks to its 128 B transmit and receive FIFOs. It can support a range of communication requirements with adjustable standard and nonstandard baud rates from 57 to 3,000,000 baud.
This interface module makes setup and communication easier by including four 10P10C (RJ50) connectors and four 10P10C to DE9M (DB9) cables. For full- and half-duplex communication, users can choose between 4- and 2-wire transceiver modes, depending on the requirements of their particular applications.
The 779539-01 is appropriate for indoor use in a variety of settings, functioning within an ambient temperature range of 0 to 55 °C and relative humidity range of 10% to 90%. Its capacity to endure storage conditions in the range of -40 to 70 °C and relative humidity of 5% to 95% guarantees long-term dependability.
This module has been tested in compliance with international standards, such as IEC-60068-2-1, IEC-60068-2-2, IEC-60068-2-27, and IEC-60068-2-56. Its resilience to shock, vibration, and environmental elements is demonstrated. Stability during operation is guaranteed by operational shock resistance of 30 g peak, half-sin, 11 ms pulse; random vibration tolerance of 5 to 500 Hz, 0.3 grms (operating) and 5 to 500 Hz, 2.4 grms (nonoperating) guarantees dependability in difficult circumstances.
