NI-VISA Remote
NI-VISA Remote Port is used primarily by National Instruments' software for remote device management and instrument control over TCP/IP networks. It facilitates communication between remote client applications and VISA-compatible devices, enabling remote configuration, monitoring, and operation of test equipment and laboratory hardware..
NI-VISA (Virtual Instrument Software Architecture) is a standard developed by National Instruments to enable communication with test instruments using various hardware interfaces including GPIB, serial, USB, and Ethernet. Port 3537 is utilized to provide remote access capabilities over networked environments, allowing software applications on different machines to interact seamlessly with VISA-enabled instruments.
Using a client-server model, the remote server component listens on port 3537 for incoming connections from client applications. These clients send VISA commands that are then routed to underlying instrument hardware. This setup simplifies management within distributed laboratory setups, enabling centralized or collaborative data acquisition and device management.
The implementation supports both TCP and UDP transport protocols for different communication needs — TCP offers reliable, connection-oriented communication suitable for control signals, while UDP provides faster, connectionless messaging ideally suited for lightweight queries or broadcast-style messaging such as device discovery.
