The NI 9871 serial module adds four RS485/RS422 serial ports to CompactRIO systems. It interfaces directly with the CompactRIO field-programmable gate array (FPGA) to offer you flexibility in communicating with serial devices. The module has individual 64 B buffers on every port that save CompactRIO FPGA space and simplify programming.
This C Series module supports standard start bit, stop bit, and handshaking settings, and has baud rates up to 1.843 MBd per port. You can pass up to 2 Mb/s of data between the module and CompactRIO.
The NI 9871 uses an external power supply to provide maximum compatibility and reliability under all serial port conditions. A 35 cm female microfit to pigtail power cable is included for quick connection to the CompactRIO external power supply. The optional PC-MF4-Y C Series microfit male to 2 female Y adapter cable is available for daisy chaining multiple NI 987x module power supplies.
NI 987x C Series modules are available in a bundle with four 10P10C modular jack to DB9 (DE9) female cables for out-of-the box connectivity.
