National Instruments 779144-01 Serial Interface Device
Part Number 779144-01 is the identifying part number for the National Instruments Serial Interface Device. This device is used for long-distance serial communication in applications where devices may be spread out over large areas such as factories and large commercial buildings. The 779144-01 features two isolated ports and works with the RS-422/RS-485 serial standard. The device can achieve a maximum baud rate of 3000 kbits/s (3 Mbps). The operating rated voltage for the RS-485 standard ranges from -7 V to +12 V. Likewise, the size of the featured FIFO buffer is 128 bytes.
The 779144-01 features both port-to-port and port-to-host isolation. Both the port-to-port and port-to-host isolation voltage is 60 VDC (CAT I) continuous. As for the power requirement, the module typically draws 380 mA from the PCI channel at +5 VDC, which can reach up to a maximum of 570 mA. The module features a DB-9 male connector for I/O purposes.
The 779144-01 measures 4.2 × 6.9 inches in physical dimensions and weighs 104 g. 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 RS485 is 30 m (in case of EMC/surge limitation but can reach up to 1.2 km without the limitation). In addition, according to the human body model, the data line ESD protection for the module is ±15 kV.
The 779144-01 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. 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.
