National Instruments 778930-01 GPIB Instrument Control Device

The 778930-01, often referred to as the PCIe GPIB, is a highly efficient IEEE 488 controller device designed by National Instruments for integration into systems with PCI Express slots. This device allows seamless integration of instruments into automated test equipment (ATE) systems using the GPIB interface, which remains the most popular interface between computers and instruments.

In order to guarantee quick and dependable communication with linked instruments, the 778930-01 is designed to attain maximum IEEE 488.2 transfer speeds. Because it has an integrated bus master DMA controller, microprocessor interruptions are eliminated, greatly increasing the efficiency of data transfer. A license for the NI‑488.2 driver software is included with this device, ensuring excellent compatibility and dependability when paired with external instruments featuring GPIB interfaces. The 778930-01 is adaptable for a range of computing environments since it supports many operating systems, such as Windows, Linux®, and Mac OS X. NI‑488.2 driver kit for Linux® and a low-profile bracket alternative are also included in the package to accommodate various installation needs.

The 778930-01 performs exceptionally well in its GPIB and HS488 modes. Data transfer rates can reach up to 1670 kbytes/s in the GPIB mode and 7980 kbytes/s in the HS488 mode, which is a huge increase. These rates guarantee that even tasks involving a lot of data are handled well, which qualifies the device for demanding industrial applications.

In terms of power consumption, the PCIe-GPIB+ version needs 360 mA on average and up to 560 mA at maximum, while the 778930-01 operates at a typical current of 320 mA and a maximum of 500 mA at +3.3 V. The device is small in size, measuring 9.754 cm by 6.888 cm (3.840 in. by 2.712 in.). It may be easily integrated into ordinary PCIe slots thanks to its IEEE 488 24-pin connector and PCI Express x1 connector.

Because of its resistance to different environmental conditions, the 778930-01 is a reliable choice for industrial environments. It runs effectively in the noncondensing range of 10% to 90% relative humidity and 0 to 55 degrees Celsius ambient temperature. As per IEC 60068-2 standards, it can withstand temperatures ranging from -20 °C to 70 °C and relative humidity levels of 5% to 95%, noncondensing.
