National Instruments 779148-01 Serial Interface Device
National Instruments part number 779148-01 is an identifying part number for the PCI-8431/8, an RS-485/RS-422 Serial Interface Device. The NI 779148-01 provides robust communication for AT serial equipment, featuring up to 2000 V of optical isolation for enhanced safety in industrial environments.
The isolated ports ensure reliable communication, even in challenging conditions such as ground loops or high common-mode voltage. With isolation between each communication port and the host PC, this device safeguards the PC and connected devices from potential damage caused by accidental high voltages or line surges. Furthermore, the 779148-01 operates with a power requirement of 1.3 A typical and 1.9 A maximum at +5 VDC.
This device supports four hardware handshaking control modes, including an advanced 2-wire DTR mode that alleviates the burden of handshaking control from the user’s application. Users can employ hardware handshaking to enable and disable their transmitters and receivers, facilitating operation on various bus topologies. Utilizing LabVIEW, an intuitive graphical development environment, users can acquire data from a wide array of instruments, including serial devices, IEEE 488.2 devices, VXI devices, programmable logic controllers, and modular DAQ boards.
Once users gather information, they can translate it into meaningful insights using powerful data analysis routines in LabVIEW. LabVIEW also provides extensive instrument drivers, significantly reducing development time as users are spared from programming low-level instrument control. The 779148-01 is outfitted with a 68-pin SCSI I/O connector, operates at a maximum baud rate of 3000 kbits per second, and features a 128-byte FIFO size.
Physically, the NI device weighs 85 grams and has dimensions of 4.2 by 5.7 inches. It operates within recommended temperature ranges of 0 to 55 °C for operation and –20 to 70 °C for storage. Humidity ranges for operation and storage are 10 to 90% and 5 to 95%, respectively.
