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.

About this Manual
The first part of this manual describes how to install and set up your
DT9836 Series module and device driver, and verify that your
module is working properly. It incorporates the content of the former
Getting Started manual.
The second part of this manual describes the features of the DT9836
Series modules, the capabilities of the DT9836 Series Device Driver,
and how to program the DT9836 Series modules using DT-Open
Layers software. Troubleshooting information is also provided.
Note: The DT9836 Series module is available either installed in a
metal BNC connection box, or as a board-level OEM version that you
can install in your own custom application. If the information in this
manual applies to all versions of the DT9836 Series module, the
manual uses the product name "DT9836 Series module." Otherwise,
the specific product name is mentioned.
Intended Audience

DT9836 Hardware Features
The DT9836 Series is a family of high-performance, multifunction
data acquisition modules for the USB (Ver. 2.0 or Ver. 1.1) bus. The
key hardware features of the DT9836 Series modules are as follows:
• Available either installed in a metal BNC connection box, or as a
board-level OEM version that you can install in your own custom
application.
• Simultaneous operation of analog input, analog output, digital
I/O, and counter/timer subsystems.
• Analog input subsystem:
16-bit A/D converters.
Throughput rate up to 225 kSamples/s.
Either 12 or 6 single-ended separate, simultaneous analog
input channels. The number of channels provided depend on
the model you purchase.
Input ranges of ±10 and ±5 V.
16
17- or 23-location channel list. You can read digital inputs, the
two 32-bit counters, and the three 32-bit quadrature decoders
using the A/D subsystem and the A/D clock. This
synchronizes digital, counter, and quadrature decoder inputs
with the analog measurements. The maximum sampling rate
when using the channel list is 225 kSamples/s.
• Analog output subsystem:
Two 16-bit D/A converters (if your module includes D/A
converters).
Output rate up to 500 kSamples/s.
Output range of ±10 V.
The DACs are deglitched to prevent noise from interfering
with the output signal.
Output channel list. You can cycle through the output channel
list using continuous output mode or waveform generation
mode.
• Digital I/O subsystem:
Overview
1
One digital input port, consisting of 16 digital input lines. You
can program any of the first eight digital input lines to
perform interrupt-on-change operations. You can read the
value of the digital input port using the analog input
channel-gain list.
One digital output port, consisting of 16 digital output lines.
You can output the value of the digital output port using the
output channel list.
• Two 32-bit counter/timer (C/T) channels that perform event
counting, up/down counting, frequency measurement,
edge-to-edge measurement, continuous pulse output, one-shot,
and repetitive one-shot operations. You can read the value of one
or more of the C/T channels using the analog input channel list.
• Three 32-bit quadrature decoders that can provide relative or
absolute position of quadrature encoder input and calculate
rotational speed. You can read the value of one or more of the
quadrature decoder channels using the analog input channel list.
• External or internal clock source.
• Trigger operations using a software command, an analog
threshold value, or an external digital trigger.
• 500 V galvanic isolation barrier that prevents ground loops to
maximize analog signal integrity and protect your computer.

Checking the System Requirements
For reliable operation, your DT9836 Series module requires the
following:
• PC with Pentium 233 MHz (or higher) processor.
• 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 38.
• One or more USB ports (Ver. 2.0 or Ver. 1.1). USB Ver. 2.0 is
strongly recommended; USB Ver. 1.1 will severely degrade
performance.
• 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.
