National Instruments 778982-01 PXI Serial Interface Module.

The part number 778982-01 from National Instruments is the identifying part number for the PXI-8430-2 PXI Serial Interface Module. This module features two ports that supports RS-232 communication standards each equipped with a DB-9 male connector. With the help of RS-232 standard, this module is able to perform high-speed communications over medium distances. The module has flexible baud rates of up to 1 Mbps, allowing for fast data transfer rates and a maximum cable length of  250 pF equivalent with a maximum CMV +25 Volts.

This module features 128 bytes FIFO buffer memory on each channel allowing for smooth communication without data loss by storing the data temporarily during data bursts or communication irregularities. This module is equipped with data line ESD protection with a voltage of up to 15 kilo Volts (human body model) ensuring durability and reliability in demanding conditions. The module’s Mean Time Between Failures (MTBF) is 448,008 hours at 25 °C, highlighting its long-term reliability. The 778982-01 requires power consumption of 0.5 W max in active mode while 50 μW max in sleep mode along with thermal dissipation of 1.5 W max at active mode and 0.5 W max at sleep mode.
 
The 778982-01 serial interface module is designed with an ingress protection rating IP40 and a pollution degree of 2. The module has an operating temperature of -40 to 70 degrees Celsius and a storage temperature of -40 to 85 degrees Celsius, making it suitable for harsher industrial environments. This module is designed to withstand the humidity level ranging from 10% to 90% (non-condensing). This module is lightweight with a weight of approximately 154 grams. 

This module is engineered to withstand operating vibrations of 5 g RMS, 10 Hz to 500 Hz that are random under the (IEC 60068-2-64) standard while operating vibration of  5 g, 10 to 500 Hz that are sinusoidal under the  (IEC 60068-2-6) standard with operating shock of 30 g, 11 ms half sine; 50 g, 3 ms half sine; 18 shocks at 6 orientations under the (IEC 60068-2-27) standard.
