Features
The DT9800 Series is a family of low-cost, multifunction data
acquisition modules for the Universal Serial Bus (USB). USB is a new
standard for connecting PCs to peripheral devices, such as printers,
mice, and modems, and was developed to make more low-cost ports
available for the increasing number of these devices.
Most new computers have two USB ports that allow direct
connection to USB devices. You can expand the number of USB
devices attached to a single USB port by using expansion hubs.
DT9800 Series function modules are part of the high-power,
bus-powered USB class; therefore, the modules do not require
external power, but the expansion hubs do require external power.
DT9800 Series function modules reside outside of the PC and install
with a single cable to ease installation. Modules can be “hot
swapped” or plugged and unplugged while the PC is on, making
them useful for many data acquisition applications.
The DT9800 Series includes the following subseries: DT9800 Standard
Series, DT9800-MAC Series, DT9800-EC Series, and DT9800-EC-I
Series.
The DT9800-EC Series modules are not isolated; the DT9800 Standard
Series, DT9800-MAC Series, and DT9800-EC-I Series modules are
isolated. In addition, the DT9800-EC and DT9800-EC-I Series
modules support the use of optional backplanes and screw terminal
panels that provide signal conditioning and other features.
