- Four RS232 or RS485/422 serial ports for NI CompactRIO
- Baud rates up to 921.6 kb/s (RS232) or 1843.2 kb/s (RS485)
- 8 to 28 VDC external power required, cable included
- Individual 64 B send-and-receive UART FIFOs per port
- 60 VDC bank isolation
National Instruments 987x serial modules add four RS232 or RS485 serial ports to NI CompactRIO systems. These C Series modules interface directly with the CompactRIO field-programmable gate array (FPGA) to offer extreme flexibility in communicating with serial devices. You can process serial data on board the FPGA through simple read-write nodes or send it to the host controller through DMA transfers for serial port access from the real-time controller.
