National Instruments 778978-01 RS-232 Serial Interface

Part Number 778978-01 is the identifying part number for the National Instruments PCI-8430/2 RS-232 Serial Interface Device. The 778978-01 comes with a set of features that makes it ideal for high-performance applications. The RS232 lines in the module have a function called Framework Access, which lets the user expand the speed of use in the model or take away data in the RAM. Likewise, the hyperthreading and multiprocessor bolster function allows the user to work with the latest PC technologies and obtain high-speed, superior work. 

The 778978-01 features two non-isolated ports and works with the RS-232 serial standard. The device can achieve a maximum transfer rate of 1000 kb/s. Likewise, the size of the featured FIFO buffer is 128 bytes. As for the power requirement, the module typically draws 325 mA of current which can reach up to a maximum of 500 mA when supplied with a +5 VDC source. 

The 778978-01 measures (4.2 in.× 5.6 in.) inches in physical dimensions and weighs 0.19 lb. Likewise, it features a DB-9 male connector for I/O connections. The module is designed for indoor use only and has an operating temperature range of 0° to 55°C and a relative humidity range of 10% to 90%. On the other hand, it can be stored at a range of -20°C to 70°C at a relative humidity of 5% to 95%. Likewise, the maximum altitude where the module can be operated properly is 2000m. Furthermore, the maximum cable length for the RS-232 is the length that corresponds to a capacitance of 2500 pF. In addition, according to the human body model, the data line ESD protection for the module is ±15 kV. 

The 778978-01 meets the requirements of the following safety standards of electrical equipment for measurement, control, and laboratory use: IEC 61010-1, EN 61010-1, UL 61010-1, and CSA 61010-1. Moreover, it complies with EMC (Electromagnetic Compatibility) requirements such as CISPR 11 (EN 55011), EN 61326 (IEC 61326), and others.
