The National Instruments WSN-3231 (Part Numbers: 781977-02, 152946C-04L) is a versatile 1-Port Programmable RS485 Serial Interface Node specifically designed for integration within NI Wireless Sensor Networks. This device facilitates wireless transmission and connects with RS485-compatible serial control boards and instruments through an established RS485 standard serial port. Engineered for low power consumption, the WSN-3231 can operate using field-replaceable AA batteries or an external power supply, which is prioritized to extend battery life when both options are connected. The device supports multiple mounting configurations, allowing for flexibility in installation, with additional mounting accessories available for separate purchase from National Instruments.

The WSN-3231 operates in two modes: node mode and router mode. In node mode, it serves as an end node that transmits requested data to the wireless gateway and associated application software. In router mode, the device not only completes its tasks but also acts as a network extender, facilitating communication for other devices to connect to the network gateway. With wireless capabilities adhering to IEEE 802.15.4 radio standards, the WSN-3231 achieves RF data rates of up to 250 Kbps and can communicate effectively over distances of up to 4,000 feet. While National Instruments has announced the mature status of the WSN-3231, the device remains available for purchase and service through Apex Waves.

For detailed specifications, the WSN-3231 measures 8.5 oz without an antenna and 9 oz with one, and it includes a 2-3 year warranty. User and maintenance manuals are also available for download. For pricing information, please contact a sales representative.
