Chapter Installation and 2 Configuration This chapter describes how to install and configure your DAQArb 5411. Installation Note: You should install your driver software before installing your hardware. Refer to the DAQArb 5411 Read Me First document for software installation information. If you have an older version of NI-DAQ already in your system, that software will not work with your device. Install NI-DAQ from the NI-DAQ software CD shipped with your DAQArb 5411. You can install the PC

Chapter 2 Installation and Configuration 8. Replace the cover. 9. Plug in and turn on your computer. The PCI-5411 or AT-5411 is now installed. Hardware Configuration The DAQArb 5411 is a fully software-configurable, Plug and Play device. Configuration information is stored in nonvolatile memory. The Plug and Play services query the device, read the information, and allocate resources for items such as base address, interrupt level, and DMA channel. After assigning these resources, the operat

Chapter 3 Signal Connections This chapter describes the I/O connectors, signal connections, and digital interface to the DAQArb 5411. I/O Connector The DAQArb 5411 has four connectors: three SMB connectors and a 50-pin mini-SCSI type connector, as shown in Figure 3-1. ARB SYNC PLL Ref Dig Out Figure 3-1.

Chapter 3 Signal Connections ARB Connector The ARB connector provides the waveform output. The maximum output levels on this connector depend on the type of load termination. If the output of a DAQArb 5411 terminates into a 50 Ω load, the output levels are ±5 V, as shown in Figure 3-2. If the output of DAQArb 5411 terminates into a high impedance load (HiZ), the output levels are ±10 V. If the output terminates into any other load, the levels are: R L V = – x 10 V out R + R L O where V is t

Chapter 3 Signal Connections SYNC Connector The SYNC connector is a transistor-transistor-logic (TTL) version of the sine waveform being generated at the output. You can think of the SYNC output as a very high frequency resolution, software-programmable clock source for many applications. You can also vary the duty cycle of SYNC output on the fly by software control, as shown in Figure 3-3. t is the time period of the sine wave being p generated and t is the pulse width of the SYNC output.
