Chapter 1
Introducing the USB-3102
Overview: USB-3102 features
This user's guide contains all of the information you need to connect the USB-3102 to your computer and to the
signals you want to control. The USB-3102 is part of the Measurement Computing brand of USB-based data
acquisition products.
The USB-3102 is a USB 2.0 full-speed device that is supported under popular Microsoft®Windows®operating
systems. The USB-3102 is fully compatible with both USB 1.1 and USB 2.0 ports.
The USB-3102 provides four channels of analog voltage output, four channels of analog current output, eight
digital I/O connections, and one 32-bit event counter.
The USB-3102 has a quad (4-channel) 16-bit digital-to-analog converter (DAC). Each D/A converter output
controls a voltage and current channel pair simultaneously.
You set the voltage output range of each DAC channel independently with software for either bipolar, unipolar
or current. The bipolar range is ±10 V, the unipolar range is 0 to 10 V, and the analog current range is 0 to
20 mA. Each voltage/current channel pair can be updated individually or simultaneously. A bidirectional
synchronization connection allows you to simultaneously update the DAC outputs on multiple devices.
The USB-3102 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.
The USB-3102 is powered by the +5 volt USB supply from your computer. No external power is required. All
I/O connections are made to the screw terminals located along each side of the USB-3102.

Connecting the USB-3102 to your system
To connect the USB-3102 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-3102.
When you connect the USB-3102 for the first time, a Found New Hardware popup balloon (Windows XP) or
dialog (other Windows versions) appears as the USB-3102 is detected by your computer.
After the USB-3102 is installed, the popup balloon or dialog states "Your new hardware is installed and ready
to use," and the power LED should flash and then remain lit. This indicates that communication is established
between the USB-3102 and your computer.
Caution! Do not disconnect any device from the USB bus while the computer is communicating with the
USB-3102, or you may lose data and/or your ability to communicate with the USB-3102.

Figure 5. USB-3102 signal pin out
Analog voltage output terminals (VOUT0 to VOUT3)
The screw terminal pins labeled VOUT0 to VOUT3 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.
Each D/A converter output controls a voltage and current channel pair simultaneously. When you write to a
voltage output, its associated current output is also updated. Each channel pair can be updated individually or
simultaneously.
Leave each pair of unused voltage and current outputs disconnected.
Analog current output terminals (IOUT0 to IOUT3)
The screw terminal pins labeled IOUT0 to IOUT3 are current output terminals (see Figure 5). The current range
for each channel is 0 to 20 mA.
Each D/A converter output controls a voltage and current channel pair simultaneously. When you write to a
current output, its associated voltage output is also updated. Each channel pair can be updated individually or
simultaneously. Leave each pair of unused voltage and current outputs disconnected.
Figure 6 shows a typical analog current output circuit. A minimum of 8 VDC must be available at IOUTn. A
maximum of 36 VDC external excitation voltage is used to power the loop. Consider the drop across the load
when selecting the supply voltage.
A typical application uses a 24 V loop supply. The loop can use either a grounded load where the supply floats,
or a grounded supply where the load floats. Each connection method is shown in Figure 6.

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 bit 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 8 and the schematic shown in Figure 9. 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).
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 and current output
channels. Three digital ground (DGND) connections provide a common ground for the DIO, CTR, SYNCLD and
+5V connections.

USB-3102 User's Guide Functional Details
17
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-3102 and simultaneously update the
DAC outputs on each device. Refer to Synchronizing multiple units below.
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-3102 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 USB 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-3102 and possibly the computer.
Synchronizing multiple units
You can connect the SYNCLD terminal pin (pin 49) of two USB-3102 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-3102 to the SYNCLD pin of the slave USB-3102.
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-3102 with the Universal Library.

Note 1: Each of the four DAC8554 outputs controls a VOUTx and IOUTx channel-pair simultaneously.
So, for example, when writing to channel VOUT0, the associated IOUT0 channel will also be
updated. Conversely, when writing to channel IOUT0, the associated VOUT0 channel is also
updated. Unused VOUTx and IOUTx output channels should be left disconnected.

Note 2: The USB-3102 output voltage level defaults to 0V whenever the output voltage range is
reconfigured.
The USB-3102 output voltage level will also default to 0V:
1) Whenever the host PC is reset, shut down or suspended.
2) If a reset command is issued to the device.
Note 3: The duration of this particular output transient is highly dependent on the enumeration process of
the host PC. Typically the output of the USB-3102 is stable after 2 seconds.
Note 4: The maximum differential non-linearity specification applies to the entire 0 to 50 °C temperature
range of the USB-3102. 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.
