National Instruments 785726-01 CompactRIO System on Module

The National Instruments 785726-01 CompactRIO System on Module is an essential part of the sbRIO-9651 Model family. It incorporates a Zynq-7020 FPGA, 512 MB DRAM, 512 MB storage, and a 667 MHz dual-core CPU into a Xilinx Zynq All Programmable System on Chip (SoC). This set of hardware components, when combined with a complete middleware solution, improves design processes and lowers risks for a variety of embedded control or monitoring applications.

Basically, the 785726-01 makes use of the ARM Cortex-A9 architecture of the Xilinx Zynq-7000 SoC, which has two cores operating at 667 MHz. The system, which runs on NI Linux Real-Time, combines the real-time performance of an operating system with the flexibility of Linux. Data handling and storage are made efficient by 512 MB of nonvolatile SLC NAND Flash memory and 512 MB of volatile DDR3 memory.

Connectivity options are extensive. The 785726-01 supports 10Base-T, 100Base-TX, and 1000Base-T Ethernet interfaces, adhering to IEEE 802.3 standards. Communication rates span 10 Mbps, 100 Mbps, and 1 Gbps, with support for both half- and full-duplex modes. With options for RS-232 and RS-485 transmission modes, the maximum baud rate for serial communication can reach 230,400 bps over five interfaces.

USB support includes one USB Host/Device interface and one USB Host-only interface, both operating at USB 2.0 Hi-Speed with a maximum data rate of 480 Mb/s per interface. With compatibility for multiple Ethernet protocols and communication rates, Secondary Ethernet (GBE1) offers further networking options.

The 785726-01 offers flexibility in UART and CAN configurations. It supports multiple UART interfaces for serial communication, featuring RS-232 and RS-485 protocols with adjustable baud rates and flow control options. Additionally, it accommodates two CAN interfaces with baud rates ranging from 10 kbps to 1 Mbps.
