National Instruments 779645-01 Serial Interface Device

The part number 779645-01 from National Instruments is the identifying part number for the PCI-8430-16 Serial Interface Device. This device is ideal for applications that require a large number of serial connections because it has 16 ports and supports the RS-232 transmission standard. The 779645-01 ensures consistent and fast data transfer with its ports, each of which can achieve a maximum baud rate of 1000 kbps. A 68-pin VHDCI connector, I/O connector which is common for efficiently managing multiple serial connections, is included on the device. Its 128 byte FIFO capacity helps with data flow control and lowers the chance of data loss during transmission.

Physically, this 779645-01 Serial Interface Device has a compact structure with dimensions of 10.67 cm by 17.52 cm (4.2 in × 6.9 in).  It was created with practicality in mind, allowing it to be easily installed without taking up much space in a variety of computer systems. Its maximum consumption at a power source of +5 VDC is 1.4 A, but its usual current is 935 mA. This device weighs only 99 grams thus making it lightweight and easy to install with reduced burden on system's power supply. 

This serial interface device is suitable to be used at a maximum height of 2000 meters and in environments with a pollution rating of 2. This device is designed to operate at a temperature of 0 degrees Celsius to 55 degrees Celsius with an operating relative humidity of 10% to 90%, noncondensing, and a suitable storage temperature of -20 degrees Celsius to 70 degrees Celsius with a storage humidity of 5% to 95%, noncondensing. This PCI module does not feature ingress protection (IP), which means that it can only be used in safe environments where dust and moisture levels are low. 

This device is appropriate for measurement, control, and laboratory use since it complies with numerous safety standards, such as IEC 61010-1, EN 61010-1, UL 61010-1, and CSA 61010-1. It may be used in areas with high electrical noise levels because it is also electromagnetically compatible, which preserves the precision and efficiency of the device.
