National Instruments 780591-01 Serial Interface Device
Part Number 780591-01 is the identifying part number for the National Instruments PCIe-8430-8 Serial Interface Device. This module is used for high-speed communications with RS-232 devices or it can also be used as a standard COM port for programs using serial communication. It is ideal for high-performance applications with features like DMA transfers, multithreading, and multiprocessor support.
The 780591-01 has eight non-isolated ports and supports baud rates from 2 baud up to a maximum rate of 1 Mbps. The baud rate accuracy is within 0.015% for standard baud rate and within 0.5% for nonstandard baud rate. Furthermore, the size of the available FIFO buffer is 128 bytes. The instrument features a 68-position VHDCI for the RS-232 Serial Interface and a single PCI Express serial board. You must convert the 68-position connector to eight DB-9 male connectors using the cable available on your kit. The module draws 200 mA (typical) or 750 mA (maximum) current when connected to a +3.3 VDC and 190 mA (typical) or 220 mA (maximum) current when supplied with +12 VDC.
The 780591-01 measures 4.38 × 6.9 inches in physical dimensions and weighs 88g. 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 RS232 should be equivalent to 2500 pF. In addition, according to the human body model, the data line ESD protection for the module is ±15 kV.
The 780591-01 meets the safety standards of IEC 61010-1, EN 61010-1, UL 61010-1, and CSA 61010-1 as electrical equipment for measurement, control, and laboratory use. Likewise, it also meets the standards 2006/95/EC and 2004/108/EC under CE compliance. Furthermore, it also meets EMC (Electromagnetic Compatibility) standards like EN 61326 (IEC 61326), EN 55011 (CISPR 11), etc.
