National Instruments 779920-01 PXI Embedded Controller

The 779920-01 is an embedded controller specifically designed for use in PXI and CompactPCI systems. This module is also identified by model name: PXIe-8106. It is commonly utilized for modular instrumentation and data acquisition (DAQ) applications. It features an Intel Core 2 Duo processor T7400 running at 2.16 GHz with a 667 MHz front-side bus (FSB). The controller is equipped with 4096 KB of on-die L2 cache that ensures faster data access and improving system responsiveness during computational processes.

The 779920-01 model comes with 512 MB of standard DDR2 RAM with the capability of expanding up to 2 GB. This ensures the controller can handle a wide range of applications and tasks from simple DAQ setups to more demanding data processing needs. The controller includes a 30 GB Serial ATA hard drive as its minimum storage option.
This embedded controller is equipped with Gigabit Ethernet (10/100/1000BASE-TX). It includes four Hi-Speed USB 2.0 ports for easy connection of peripherals and external devices. The controller also offers a GPIB (IEEE 488) interface which is essential for communication with other instrumentation devices in test setups. Other I/O options include serial (RS-232) and parallel ports.

The 779920-01 module supports both PXI Express 4 and PXI Express 2 link configurations. The PXI Express 4 Link Configuration allows for three x4 links and one x1 link while the PXI Express 2 supports two x4 links. The controller is a four-wide 3U PXI Express module and requires one system slot along with three controller expansion slots. It is fully compatible with PXI Express Specification 1.0. It has a typical weight of 0.97 kg (2.14 lbs) which makes it manageable for standard PXI chassis installations.

This NI 779920-01 controller operates at several voltage levels, including + 3.3 V, + 5 V, + 5 V standby and + 12 V with specific current ratings provided for typical and maximum conditions. It is designed to work in environments with pollution degree 2, indoor use and a maximum altitude of 2000 meters. The model has an operational temperature range of 5 to 50 °C with an extended temperature option available for harsher environments allowing it to operate from 0 to 55°C.
