Product specs for National Instruments Corporation 779891-03

The NI 9870 serial module adds four RS232 serial ports to NI CompactRIO systems. With an NI LabVIEW FPGA API, the four ports are accessed directly from 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 921.6 kb/s per port. You can pass up to 1.28 Mb/s of data between the module and CompactRIO.

The NI 9870 uses an external power 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.
