LabVIEW Serial Port API

LabVIEW Serial Port API by Martin Henz Systemtechnik is a lightweight, well-structured library that streamlines serial communication in LabVIEW. Built on NI-VISA, it provides a clear, consistent set of VIs for opening, configuring, reading, writing, and closing serial ports, so you can connect to instruments, controllers, and embedded devices quickly and reliably.

Key features:

• VISA-based serial communication for RS-232/422/485
• Simple configuration of baud rate, data bits, parity, stop bits, and timeouts
• Hardware and software flow control (RTS/CTS, DTR/DSR, XON/XOFF)
• Support for ASCII and binary data, termination characters, custom delimiters, and fixed-length frames
• Clean error handling via LabVIEW error clusters
• Concurrent communication with multiple ports
• Reusable patterns for robust, polled I/O (e.g., producer/consumer loops)
• Port enumeration and availability checks to simplify deployment

Typical use cases:

• Instrument control and test automation
• Communication with microcontrollers and embedded boards
• Barcode scanners, printers, and industrial peripherals
• PLCs, gateways, and field sensors

Benefits:

• Faster integration and reduced boilerplate code
• Consistent, maintainable API across projects and teams
• Improved reliability through clear configuration and error handling

System requirements:

• LabVIEW with NI-VISA support on the target platform

This API helps LabVIEW developers build dependable serial interfaces with minimal effort, offering a pragmatic balance between simplicity and flexibility for a wide range of applications.
