National Instruments NI-9870 C Series Serial Interface Module

The NI-9870 Serial Interface Module (part numbers: 779891-02, 779891-03, 198850E-01L, 195926A-01)  adds serial RS232 ports to CompactRIO frameworks. Serial ports have coordinate access from the FPGA to offer users adaptability when communicating with serial gadgets, in each port that spare space in the FPGA and rearrange programming. The NI 9870 4-port RS-232 Interface utilizes outer capacity to give the most extreme similarity and dependability in all serial port conditions. Users should associate an outside power supply to the NI 9870. This power supply gives the ability to the RS232 handsets on the module. The user can utilize the included female four-position braid to interface with an outer voltage source. The NI-9870 has four full-highlighted, autonomous RS232 DTE ports that are confined from alternate modules in the framework. Each port is completely compatible with the ANSI/EIA/TIA-232 standard.

There are two versions of the NI-9870 module. The first one, part number 779891-02, is not conformal coated. The second part number, 779891-03, is conformal coated. The module has individual 64 B buffers on each port that save CompactRIO FPGA space and rearrange programming. This C Series module bolsters standard begin bit, stop bit, and handshaking settings and highlight baud rates up to 921.6 kbit/s per port. Users can pass up to 2 Mbit per second of information between these modules and CompactRIO. The device has a power consumption of 0.5 W maximum when active, while it consumes up to 50 µW when in sleep mode.

This model comes with 4 RS232 (TIA/EIA-232) or 4 RS485/RS422 serial ports for CompactRIO, baud rates from 14 bit/s to 921.6 kbit/s, individual 64 B UART FIFO supports per port, 8 to 28 VDC remotely fueled; and a PC-MF4-PT link included. It has a maximum cable length of 250 pF equivalent. The NI 9870 is run using the NI-RIO driver software which is compatible with software packages like LabVIEW development system, LabVIEW FPGA module, Visual C#, or Visual C++.

The NI device weighs 5.4 oz. It has a recommended operating temperature range of -40 °C to 70 °C, a storage temperature range of -40 °C to 85 °C, a random and sinusoidal operating vibration of 5 grms and 5g respectively – at a frequency range of 10 to 500 Hz.
