Getting Started with the NI 783xR This document explains how to install and configure the National Instruments 783xR. Introduction The NI 783xR devices are R Series Reconfigurable I/O (RIO) devices with 16-bit analog input (AI) channels, 16-bit analog output (AO) channels, and digital I/O (DIO) lines. • The NI PXI-7830R and NI PCI-7830R have four independent AI channels, four independent AO channels, and 56 DIO lines. • The NI PXI-7831R/7833R and NI PCI-7831R/7833R have eight independent AI channels, eight independent AO channels, and 96 DIO lines. Traditional I/O devices have a fixed functionality provided by an application-specific integrated circuit (ASIC), but the NI 783xR has an FPGA (Field-Programmable Gate Array) that allows you to define device functionality and timing. You can use the LabVIEW FPGA Module to graphically design the NI 783xR timing and functionality without having to learn a low-level programming language or a hardware description language (HDL) traditionally used for FPGA design. With the LabVIEW FPGA Module, you create or download a custom virtual instrument (VI) to the FPGA. You can reconfigure the NI 783xR with a new VI at any time. You can use the LabVIEW Real-Time Module to communicate with and control the NI 783xR while performing additional tasks, such as real-time floating-point processing and data logging. Note If you are using LabVIEW but not the LabVIEW FPGA Module, you can create VIs that run in LabVIEW to control existing FPGA VIs, but you cannot create new FPGA VIs. The NI 783xR has Flash memory that you can use to store a startup VI. You can configure the VI to load to the FPGA and to run when the device powers up.

Using Remote NI 783xR Devices The following sections discuss working with remote NI 783x devices. Configuring and Accessing Remote FPGA Targets The NI 783x, which is an FPGA target, might be located in other systems on the network, which are known as remote systems. The FPGA Module uses the NI-VISA communication protocol to locate FPGA targets in remote systems, which are known as remote FPGA targets. MAX detects remote FPGA devices as VISA resources and displays them in the Devices and Interfaces category for the remote system they are connected to. To make remote FPGA targets accessible to other computers on the network, you run the NI-VISA Server on the remote system. The NI-VISA Server is a tool that enables users on a network to access VISA resources on the computer on which the NI-VISA Server is running. The NI-VISA Server can run on networked RT targets, located both on and off the local subnet, and Windows computers. After you install and start the NI-VISA Server on the remote system, you must grant access permissions to the remote system in MAX, as described in the Setting Access Permissions for Remote FPGA Targets section. When the FPGA target appears in MAX, verify that you can access the FPGA © National Instruments Corporation 11 Getting Started with the NI 783xR target, as described in the Verifying Communication with Remote FPGA Targets section. If you cannot verify access to the remote FPGA target using MAX or if you receive an error message when attempting to add the remote FPGA target to the Project Explorer window in LabVIEW, verify that you correctly set access permissions. You then can add the remote system to the Project Explorer window in LabVIEW. Refer to the LabVIEW Help for information about adding the remote system to the Project Explorer window. The LabVIEW Help is available by clicking Help»Search the LabVIEW Help in LabVIEW. Note The NI-VISA server starts automatically after it is installed on an RT target. Verifying Communication with Remote FPGA Targets Complete the following steps to test communication with a remote system in MAX. 1. Expand the Remote Systems category in MAX. 2. Expand the remote system in which the FPGA target is installed and Devices and Interfaces so you can view the FPGA targets installed in that system. 3. Select the FPGA target you want to test and click the Open VISA Test Panel button, shown at left. If the VISA test panel opens, you have access to the remote FPGA target and you can add the remote FPGA target to the Project Explorer window in LabVIEW. If the test panel does not open or if you receive an error message when attempting to add the remote FPGA target to the Project Explorer window in LabVIEW, refer to the Setting Access Permissions for Remote FPGA Targets section. Setting Access Permissions for Remote FPGA Targets If you cannot verify communication with a remote system in MAX or if you receive an error message when attempting to add the remote FPGA target to the Project Explorer window in LabVIEW, you might need to set access permissions for the remote system. Complete the following steps to allow other computers to access the remote FPGA target. Getting Started with the NI 783xR 1. Make sure the remote FPGA target appears in MAX. If you cannot locate the remote system and FPGA target in MAX, refer to the Measurement & Automation Explorer Help by selecting Help»MAX Help in MAX for information about recognizing remote systems in MAX. 2. If the NI-VISA Server is running on an RT target, select the RT target under the Remote Systems category in MAX. If the NI-VISA Server 12 ni.com is running on a Windows computer, open MAX on that computer and proceed to the next step. 3. For RT targets, open the VISA Options page by clicking the Remote Systems»Remote System Name»Software»NI-VISA x.x category, where Remote System Name is the name or IP address of the remote system and x.x is the version of NI-VISA you have installed, and then clicking the VISA Options tab. For Windows computers, open the VISA Options page by selecting Tools»NI-VISA»VISA Options. 4. On the VISA Options page, select VISA Server»Security to view the Remote Access List, as shown in Figure 1. Figure 1. Setting Access Permissions for Remote Systems 5. © National Instruments Corporation Click the Add button, shown at left, and enter the name or IP address of the computer to add a computer to the Remote Access List. You can use the * wildcard to specify a group of computers or all computers on the network. In general, use the * wildcard to set up general allowances or denials, and follow those entries with more specific entries. Refer to the LabVIEW Help, available by selecting Help»Search the 13 Getting Started with the NI 783xR LabVIEW Help, for general information about access list entries and wildcards. 6. Select a Permission option to either allow access to the remote system or deny access to the remote system. 7. Click the Save button, shown at left, to set the access permissions.
