It is an asynchronous interface for communicating with instruments through the serial port. This model has plug-and-play compatibility with Microsoft 2000, NT, XP, Me, and 9x. Thus, it brings the advantage of automatic configuration for hassle free installation. This device can easily be installed as a standard serial port from the user’s current applications, such as Visual Basic, Excel Visual, C++, etc.

The 4-port version of the NI PXI-8423 comes with modular, 10-position phone jacks.
