Radio and Television Interference
This equipment has been tested and found to comply with CISPR
EN55022 Class A, and EN50082-1 (CE) requirements and also with
the limits for a Class A digital device, pursuant to Part 15 of the FCC
Rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and used in
accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in
a residential area is likely to cause harmful interference, in which case
the user will be required to correct the interference at his own
expense.
Changes or modifications to this equipment not expressly approved
by Data Translation could void your authority to operate the
equipment under Part 15 of the FCC Rules.
Note: This product was verified to meet FCC requirements under
test conditions that included use of shielded cables and connectors
between system components. It is important that you use shielded
cables and connectors to reduce the possibility of causing
interference to radio, television, and other electronic devices.
Canadian Department of Communications Statement
This digital apparatus does not exceed the Class A limits for radio
noise emissions from digital apparatus set out in the Radio
Interference Regulations of the Canadian Department of
Communications.
Le présent appareil numérique n’émet pas de bruits radioélectriques
dépassant les limites applicables aux appareils numériques de la class
A prescrites dans le Règlement sur le brouillage radioélectrique
édicté par le Ministère des Communications du Canada.

The DT9800 Series is a family of low-cost, multifunction data
acquisition modules for the Universal Serial Bus (USB) (Ver. 1.1 or
Ver. 2.0).
Most computers have two or more 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 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 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-EC Series, and DT9800-EC-I Series.
16
The DT9800-EC Series modules are not isolated; the DT9800 Standard
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. Table 1 lists the modules in each
series and the key features of each.

All DT9800 Series modules share the following major features:
• One 8-bit digital input port and one 8-bit digital output port; the
digital input lines can be included as part of the analog input
channel-gain list to correlate the timing of analog and digital
events; digital outputs can drive external solid-state relays
• Two 16-bit user counter/timers programmable for event
counting, frequency measurement, rate generation (continuous
pulse output), one-shot, and repetitive-one shot pulse output
operations
• USB compatibility
• Software configurable termination resistance for differential
inputs on a channel-by-channel basis
• Input gains of 1, 2, 4, and 8 for all modules except the DT9805 and
DT9806, which support gains of 1, 10, 100, and 500
18
• Continuously paced and triggered scan capability
• A 32-location channel-gain list that supports sampling analog
input channels at the same or different gains in sequential or
random order
• Internal and external clock sources for the analog input
subsystem
• Digital TTL triggering for the analog input subsystem
• One dynamic digital output line
• Programmable gate types and pulse output types
In addition, the DT9805 and DT9806 modules provide thermocouples
and low-level analog input capability. A software calibration utility is
provided for calibrating the analog I/O subsystems of all modules.

Checking the System Requirements
For reliable operation, your DT9800 Series modules require the
following:
• PC with Pentium 233 MHz (or higher) processor.
• One or more USB ports (Ver. 1.1 or Ver. 2.0). USB Ver. 2.0 is not
required and will not improve performance for this module.
• Windows 2000 or Windows XP (Professional Edition) operating
system.
For USB Ver. 2.0 support, make sure that you install Service Pack
2 (for Windows XP) or Service Pack 4 (for Windows 2000). In
addition, for some systems, you may have to disable standby
mode. If you are not sure whether you are using USB Ver. 1.1 or
Ver. 2.0, run the Open Layers Control Panel applet, described on
page 45.
• 64 MB (or more) of RAM; 128 MB (or more) recommended.
• One or more CD-ROM drives.
28
• Super VGA (800 x 600 or higher resolution) display monitor.
Once you have verified that your system meets the system
requirements, install the software as described in the next section.
