Stand-alone Data Logger Features of DI-71X Products

Key Features

Built-in Secure Digital (SD) socket

Allows one of our Data Loggers to use the same popular and very economical memory cards used by consumer electronic devices like MP3 players and digital cameras. Recommended Memory Card: SanDisk Secure Digital Card (available through the online store).

SD Memory capacities from 16 MB to 2 GB

Allows the data logger to store large amounts of data. Record times can be very lengthy, even at the fastest sample rates.

Built-in real time clock

Transparently time and date stamps acquired data to facilitate data review and analysis.

Multifunction push-button control

Allows simplified manual start/stop local control over the recording process.

Circular FIFO or Record-until-full memory configuration options

Allows the Data Logger to record continuously using a circular buffer approach or to terminate data logging upon filling its SD memory. Use the calculator and the chart below to determine length of recording sessions.

Overview

Our stand-alone data loggers are in a price and performance class entirely their own. These data loggers are the first in their price range to offer data logger server capability. Acting as a server allows stand-alone data logger versions of the DI-710 Series, DI-715B Series, and DI-718B Series to locally and independently acquire data to their removable Secure Digital Card (SD) memories, and then make that acquired data available upon demand. This demand aspect can be the simple act of physically removing SD memory, transporting it to a reader on another computer, then uploading the information for review and analysis. However, stand-alone data logger units also allow information acquired to their SD memory to be uploaded via the Ethernet interface using the provided uploader software. The USB interface requires that a PC be located within 5 meters (15 feet) of the data logger. But the Ethernet option allows data access from anywhere on a local area network (LAN). A Data Logger configured for stand-alone data logger operation and an Ethernet interface transparently becomes like any other computer on the network, able to share data whenever and wherever it is needed. This can be over the LAN to a PC on the other side of the facility, or over the Internet to a PC on the other side of the world. Furthermore, stand-alone data logger instruments can be easily added to existing networks. Its server functionality means that it does not require a dedicated network to operate efficiently. Data is locally stored to SD memory, where it is available for upload only on demand and as network bandwidth permits. In this manner, stand-alone data logger instruments with Ethernet interfaces are fully compatible with the intrinsic non-preemptive nature of Ethernet networks.

Removable Storage Slot – Accommodates standard and readily available multi-media memory cards for mass storage. These are the same memories used by consumer electronic devices like MP3 players and digital cameras. Accepts memory sizes from 16 MB to 2 GB.

SD Memories Secure Digital Cards (SD) are small compact storage devices used in many digital media devices such as MP3 players and digital cameras. Record data directly to SD with stand-alone data loggers. To see how much data can be stored to your SD card use the chart below for a general idea or use the Record Time Calculator for a more precise figure.

Total Record Times Use the table to the left to estimate how long you can record data at a specified throughput rate as a function of memory size. Use our record time calculator to precisely determine record time in days, hours, minutes and seconds.

View the DemoConfiguration Panel The provided configuration software (screen shot at right) allows quick and easy configuration of your stand-alone data logger. Change the number of enabled channels, channel configuration (including gain and input type), sample rate, digital configuration, and memory configuration. Conveniently save and load repeatedly used settings. Also allows you to set the instrument clock so you will always be able to find the data you need, since is it precisely correlated with the date and time of acquisition. View the Demo.
