For High Resolution Image: http://www.ggcomm.com/DTQ_Images/718B.JPG See JPEG. jpg - JPEG The DI-718B Series instruments are the first to combine the features of integrated, low-cost isolated amplifiers and the ability to record to Secure Digital (SD) memory cards. SD cards are removable compact storage devices used in many consumer digital media devices such as MP3 players and digital cameras. Depending on the model, the 14-bit, eight-channel instruments either stream data to a PC or collect data as a stand-alone data logger data logger - data logging . They are available with either USB USB in full Universal Serial Bus Type of serial bus that allows peripheral devices (disks, modems, printers, digitizers, data gloves, etc.) to be easily connected to a computer. or Ethernet interface. At the same time, DATAQ has announced the release of its isolated amplifier modules. The DATAQ DI-8B Modules integrate with DI-718B instruments and are half the cost of competing products. They are the world's smallest, fully functional, isolated analog signal An analog or analogue signal is any time continuous signal where some time varying feature of the signal is a representation of some other time varying quantity. It differs from a digital signal in that small fluctuations in the signal are meaningful. conditioners. When the new modules are inserted into a DI-718B instrument, the resulting system is one small box measuring only 5.4 x 4.1 x 1.5 inches (14 x 11 x 4 cm). Competitive solutions require two boxes - one for signal conditioning Imagine feeding the output of a temperature sensor, which is in millivolts, to an Analog-to-digital converter to be processed. Is it possible for the Analog-to-Digital converter to process such a minute voltage amplitude? The answer is probably no. and a second for data acquisition. Because of their compact design, the DI-718B instrument and DI-8B modules combine to form the smallest data acquisition/logging system in its class. Most Features in Its Price Range At a cost-per-channel as low as $163 for eight isolated inputs, the DI-718B Series is the most competitively priced, amplified and isolated data acquisition/logging solution on the market. Yet it offers advanced features usually reserved for more expensive instruments. These include a channel scan list, high-resolution analog-to-digital conversion analog-to-digital or A/D conversion, the process of changing continuously varying data, such as voltage, current, or shaft rotation, into discrete digital quantities that represent the magnitude of the data , high sample-rate throughput, and advanced computer interface options. Channel Scan List A built-in programmable scan list allows channel numbers to be dynamically selected during scanning to precisely match signal requirements on a channel-by-channel basis. High Resolution 14-bit resolution analog-to-digital conversion provides a responsive instrument capable of registering changes as small as one part in 16384 (0.006% of the full scale measurement range). High Sample Rate Throughput All DI-718B products have eight analog input Refers to hardware interfaces that accept non-digital signals. For decades, all the plugs and sockets on traditional audio and video equipment connected analog lines (see illustration below). channels, each of which is capable of accepting a DI-8B amplifier module. PC-tethered instruments stream data to the PC at a 4800-sample-per-second throughput rate Throughput rate is an obsolete term[1] in the terminology of automated chemical analysis. It may mean either:

Stand-alone instruments store data to their SD memory cards at a maximum sample throughput rate of 14400 samples per second. SD memory cards are commonly available and support memory capacities of 8 MB to 1 GB. Server Capability These systems are the first in their price range to offer data-acquisition server capability. Operating in stand-alone mode, a DI-718B instrument can supply data upon request, via an Ethernet network. This eliminates the need to remove the SD memory card and physically carry the data to a PC for analysis. Instead, engineers can obtain data remotely, over a LAN (Local Area Network) A communications network that serves users within a confined geographical area. The "clients" are the user's workstations typically running Windows, although Mac and Linux clients are also used. to a PC on the other side of a facility, or over the Internet to a PC on the other side of the world. Applications The DI-718B is a robust instrument that can be applied to nearly any industrial data acquisition or logging situation that requires a tough, amplified, and isolated solution. Data acquisition applications include monitoring industrial machinery for maintenance and troubleshooting, in-vehicle automotive testing, and timing and amplitude measurements on presses and mill equipment. Stand-alone data logging (data) data logging - (data acquisition) Storing a series of measurements over time, usually from a sensor that converts a physical quantity such as temperature, pressure, relative humidity, light, resistance, current, power, speed, vibration into a voltage that is then converted is used when a PC cannot be located near the instrument for fear of theft or damage, when the location is remote, or when a PC cannot be dedicated to an ongoing data collection application. DI-8B amplifier modules may be mixed and matched within the DI-718B to precisely address any application requirement. Typical measurements are AC/DC AC/DC adj. Slang Having a bisexual orientation.

Further, the intrinsic isolation of DI-8B amplifiers allows successful measurements in the presence of common mode voltages that would literally destroy similarly priced, but non-isolated competitive products Input-to output isolation is maintained up to 1000 VDC VDC Volts Direct Current VDC Venture Development Corporation VDC Vehicle Dynamic Control VDC Village Development Committee (Nepal) VDC Virtual Data Center VdC Verband der Cigarettenindustrie or peak AC. Channel-to-channel isolation is 500 VDC or peak AC. Power for the instrument may be any 9-36 VDC source. An AC adapter Same as power adapter. is provided that supports U.S. and international power standards. Supporting Software The DI-718B series of data acquisition instruments is supported by a suite of included software modules. WinDaq/Lite software provides a ready-to-run, no programming environment for acquiring, displaying, recording, reviewing, analyzing, and exporting waveform information for PC-tethered or stand-alone configurations. WinDaq/HS is similar to WinDaq/Lite, except it allows throughput-to-disk rates of 4800 Hz. In addition, a stand-alone utility is included that allows a complete data acquisition configuration to be designed and downloaded to the DI-718B from any local or remote PC for stand-alone applications. Also it provides the ability to upload data stored to the SD memory over the instrument's optional Ethernet interface. Finally, an ActiveX Control library permits access to DI-718B functions using Windows(R) programming languages such as VisualBASIC and C++. Price and Availability All models in the DI-718B Series are available from stock beginning July 1, 2005. SD memory cards are priced at $35 to $79, depending on the amount of memory.
