Chapter 1
Introducing the USB-3114
Overview: USB-3114 features
This user's guide contains all of the information you need to connect the USB-3114 to your computer and to the
signals you want to measure. The USB-3114 is part of the Measurement Computing brand of USB-based data
acquisition products.
The USB-3114 is a USB 2.0 full-speed, high-drive device that is supported under popular Microsoft®
Windows® operating systems. The USB-3114 is fully compatible with both USB 1.1 and USB 2.0 ports.
The USB-3114 provides 16 channels of high-drive analog voltage output, high output current, eight digital I/O
connections, and one 32-bit event counter.
Each of the voltage outputs of the USB-3114 incorporates high-drive current output capability. The high drive
current outputs allow each of the voltage outputs to sink/source up to 40 mA (maximum) of load current.
Caution! The USB-3114 voltage outputs should not be kept in a short-circuit condition for longer than the
specified 100 ms. For those applications that may potentially exceed the 40 mA maximum current
limit or the 100 ms short-circuit condition, external current limiting must be used to prevent
potential damage to the USB-3114.
The USB-3114 has four quad (4-channel) 16-bit digital-to-analog converters (DAC). You set the voltage output
range of each DAC channel independently with software for either bipolar or unipolar. The bipolar range is
±10 V, and the unipolar range is 0 to 10 V. The outputs may be updated individually or simultaneously.
The USB-3114 features eight bidirectional digital I/O connections. You can configure the DIO lines as input or
output in one 8-bit port. All digital pins are floating by default. A screw terminal connection is provided for
pull-up (+5 V) or pull-down (0 volts) configuration.
The 32-bit counter can count TTL pulses. A bidirectional synchronization connection allows you to
simultaneously update the DAC outputs on multiple devices.
The USB-3114 is powered by a 5 volt, 2 amp AC power adapter that is shipped with the board. All I/O
connections are made to the screw terminals located along each side of the USB-3114.

USB-3114 User's Guide Installing the USB-3114
Connecting the USB-3114 to your system
To connect the USB-3114 to your system, turn your computer on, and connect the USB cable to a USB port on
your computer or to an external USB hub that is connected to your computer. The USB cable provides power
and communication to the USB-3114.
When you connect the USB-3114 to a computer for the first time, a Found New Hardware dialog opens when
the operating system detects the device. When the dialog closes, the installation is complete. After the
USB-3114 is installed, the USB LED should flash and then remain lit. This indicates that communication is
established between the USB-3114 and your computer.
Caution! Do not disconnect any device from the USB bus while the computer is communicating with the
USB-3114, or you may lose data and/or your ability to communicate with the USB-3114.
If the USB LED turns off
If the USB LED is illuminated but then turns off, the computer has lost communication with the USB-3114. To
restore communication, disconnect the USB cable from the computer, and then reconnect it. This should restore
communication, and the LED should turn back on.
Calibrating the USB-3114
The USB-3114 is shipped fully calibrated. Calibration coefficients are stored in the device FLASH memory.
Return the device to Measurement Computing Corporation when calibration is required. The normal calibration
interval is once per year.

Figure 7. Schematic showing DIO7 detecting the state of a switch
Figure 5. USB-3114 signal pin out
Analog voltage output terminals (VOUT0 to VOUT15)
The screw terminal pins labeled VOUT0 to VOUT15 are voltage output terminals (see Figure 5). The voltage
output range for each channel is software-programmable for either bipolar or unipolar. The bipolar range is
±10 V, and the unipolar range is 0 to 10 V. The channel outputs may be updated individually or simultaneously.
Digital I/O terminals (DIO0 to DIO7)
You can connect up to eight digital I/O lines to the screw terminals labeled DIO0 to DIO7 (pins 21 through 28).
You can configure each digital port for either input or output.
When you configure the digital bits for input, you can use the digital I/O terminals to detect the state of any
TTL level input. Refer to the switch shown in Figure 6 and the schematic shown in Figure 7. When the switch
is set to the +5 V USER input, DIO7 reads TRUE (1). If you move the switch to DGND, DIO7 reads
FALSE (0).
For more information on digital signal connections
For more information on digital signal connections and digital I/O techniques, refer to the Guide to Signal
Connections (available on our web site at www.mccdaq.com/pdfs/DAQ-Signal-Connections.pdf).
14
USB-3114 User's Guide Functional Details
Digital I/O control terminal (DIO CTL) for pull-up/down configuration
All digital pins are floating by default. When inputs are floating, the state of unwired inputs are undefined (they
may read high or low). You can configure the inputs to read a high or low value when they aren’t wired. Use
the DIO CTL connection (pin 54) to configure the digital pins for pull-up (inputs read high when unwired) or
pull-down (inputs read low when unwired).
To pull up the digital pins to +5V, wire the DIO CTL terminal pin to the +5V terminal pin (pin 56).
To pull down the digital pins to ground (0 volts), wire the DIO CTL terminal pin to a DGND terminal pin
(pin 50, 53, or 55).
Ground terminals (AGND, DGND)
Eight analog ground (AGND) connections provide a common ground for all analog voltage output channels.
Three digital ground (DGND) connections provide a common ground for the DIO, CTR, SYNCLD and +5V
connections.
Synchronous DAC load terminal (SYNCLD)
The synchronous DAC load connection (pin 49) is a bidirectional I/O signal that allows you to simultaneously
update the DAC outputs on multiple devices. You can use this pin for two purposes:
Configure as an input (slave mode) to receive the D/A LOAD signal from an external source.
When the SYNCLD pin receives the trigger signal, the analog outputs are updated simultaneously.
SYNCLD pin must be logic low in slave mode for immediate update of DAC outputs
When the SYNCLD pin is in slave mode, the analog outputs can be updated immediately or when a positive
edge is seen on the SYNCLD pin (this is under software control.)
The SYNCLD pin must be at a low logic level for DAC outputs to update immediately. If the external source
supplying the D/A LOAD signal is pulling the SYNCLD pin high, no update will occur.
Refer to the "USB-3100 Series" section in the Universal Library User's Guide for information on how to
update DAC outputs immediately.
Configure as an output (master mode) to send the internal D/A LOAD signal to the SYNCLD pin.
You can use the SYNCLD pin to synchronize with a second USB-3114 and simultaneously update the
DAC outputs on each device. Refer to Synchronizing multiple units section on page 16.
Use InstaCal to configure the SYNCLD mode as master or slave. On power up and reset the SYNCLD pin is
set to slave mode (input).
Refer to the "USB-3100 Series" section in the Universal Library User's Guide for information on how to
configure the USB-3114 with the Universal Library.
Counter terminal (CTR)
The CTR connection (pin 52) is the input to the 32-bit event counter. The internal counter increments when the
TTL levels transition from low to high. The counter can count frequencies of up to 1 MHz.
Power terminal (+5V)
The +5 V connection (pin 56) draws power from the external power connector. This terminal is a +5V output.
Caution! The +5V terminal is an output. Do not connect to an external power supply or you may damage
the USB-3114 and possibly the computer.
15
USB-3114 User's Guide Functional Details
Synchronizing multiple units
You can connect the SYNCLD terminal pin (pin 49) of two USB-3114 units together in a master/slave
configuration and simultaneously update the DAC outputs of both devices. Do the following.
1. Connect the SYNCLD pin of the master USB-3114 to the SYNCLD pin of the slave USB-3114.
2. Configure the SYNCLD pin on the slave device for input to receive the D/A LOAD signal from the master
device. Use InstaCal to set the direction of the SYNCLD pin.
3. Configure the SYNCLD pin on the master device for output to generate an output pulse on the SYNCLD
pin.
Set the Universal Library SIMULTANEOUS option for each device. Refer to the Universal Library User's Guide
for information on how to configure the USB-3114 with the Universal Library.
When the SYNCLD pin on the slave device receives the signal, the analog output channels on each device are
updated simultaneously.
An example of a master/slave configuration is shown here.

Note 2: The duration of this particular output transient is highly dependent on the enumeration process of
the host PC. Typically the output of the USB-3114 is stable after 2 seconds.
Note 3: The maximum differential non-linearity specification applies to the entire 0 to 50 °C temperature
range of the USB-3114. This specification also accounts for the maximum errors due to the
software calibration algorithm (in Calibrated mode only) and the DAC8554 digital to analog
converter non-linearities.
Note 4: The USB-3114 voltage outputs should not be kept in a short-circuit condition for longer than the
specified limit of 100 ms. For those applications that may potentially exceed the 40 mA
maximum current limit or the 100 ms short-circuit condition, external current limiting must be
used to prevent potential damage to the USB-3114.

The pull down configuration requires the DIO CTL pin (pin 54) to be connected to a DGND pin
(pin 50, 53 or 55). For a pull up configuration, the DIO CTL pin should be connected to the +5V
terminal pin (pin 56).
Synchronous DAC Load
Note 6: SYNCLD is a Schmitt trigger input and is over-current protected with a 200 Ohm series resistor.
Note 7: When SYNCLD is in input mode, the analog outputs may either be updated immediately or when
a positive edge is seen on the SYNCLD pin (this is under software control.) However, the pin
must be at a low logic level in order for the DAC outputs to be updated immediately. If an
external source is pulling the pin high, no update will occur.
