The new OM-USB-3101, OM-USB-3103, and
OM-USB-3105 are voltage output USB 2.0 full-speed
modules. Each module provides 4, 8, or 16 voltage
outputs. All modules provide synchronous and
concurrent voltage updates.
All OM-USB-3100 Series modules provide eight
digital I/O lines and one 32-bit event counter and are
powered by the 5V USB supply from the computer.
All OM-USB-3100 Series modules provide either
4, 8, or 16 channels of 16-bit analog output.
Each channel is software-selectable for either a bipolar
voltage output range of ±10 V or unipolar range of
0 to 10V. Channel outputs can be updated individually
The OM-USB-3100 Series modules ship with an
impressive array of software including the new
TracerDAQ®, a full-featured, out-of-the-box data
logging, viewing, and analysis application.
Driver support and detailed example programs are
included for Universal Library programming libraries for
Microsoft® Visual Studio® programming languages, and
other languages, including DASYLab®, and ULx for NI
LabVIEW® (comprehensive library of Vls and example
programs compatible with 32-bit and 64-bit LabVIEW
v8.5 through 2012) and InstaCalTM installation,
calibration and test utility-powerful solutions for
programmers and nonprogrammers alike. These
modules operate under Microsoft Windows® XP (32-bit
only) and VISTA/7 AND 8 (32-bit and 64-bit) operating
Synchronous DAC Updates
All OM-USB-3100 Series modules have a
synchronous DAC load connection pin (SYNCLD)
that simultaneously updates DAC outputs on multiple
devices. You can configure this with software as an
input (slave mode) or as an output (master mode).
In slave mode, the SYNCLD pin receives the D/A
LOAD signal from an external source. When the
SYNCLD pin receives the trigger signal, the analog
outputs are updated simultaneously.
In master mode, the internal D/A LOAD signal is sent
to the SYNCLD pin. You can then synchronize with a
second device of the same type and simultaneously
update the DAC outputs on each device.
On power up and reset, the SYNCLD pin is set to
slave mode (input).
All OM-USB-3100 Series modules have eight
bidirectional digital I/O connections. The digital DIO lines
can be independently programmed for input or output.
All digital pins are floating by default. A screw terminal
connection is provided to configure for pull-up (5V) or
Each OM-USB-3100 Series module has a 32-bit event
counter for counting TTL pulses. The counter increments
when the TTL levels transition from low to high. The
counter accepts frequency inputs of up to 1 MHz.
