- Specifications
The NI 9870E is a C Series module from National Instruments that provides four independent RS232 serial ports for communication with a wide range of serial devices. Designed for use with CompactRIO and CompactDAQ systems, the 9870E enables high-speed, reliable serial data transfer and is ideal for industrial automation, data acquisition, and embedded control applications. The board-only version allows for integration into custom enclosures or systems where space and form factor are critical. Each port supports standard RS232 signaling and baud rates up to 921.6 kbps. The module is engineered for robust performance in demanding environments and is compatible with NIs LabVIEW software for easy configuration and programming.
