Description
The National Instruments PXI-8422/4 PXI Serial Interface Module, with Part Number 777736-04, is an advanced interface designed for high-speed communications, featuring four RS-232 ports with 2000 V optical port-to-port isolation to ensure signal integrity and noise resistance. Each port has a FIFO size of 64 B for transmit and receive operations, which can be expanded to 128 B for the PXI-8422/4, and utilizes DE9M (DB9) connectors, although cables are not included with the module.
Capable of handling standard baud rates up to 115.2 kb/s, this module ensures swift and reliable data transfer. It operates on a TCP/IP communication protocol and is built on a full-duplex multidrop bus architecture, allowing efficient communication in complex systems. Despite its obsolete status, the PXI-8422/4 remains accessible for purchase and repairs through Apex Waves, providing continued support for existing setups.
