Chapter 1
Introducing the USB-3105
Overview: USB-3105 features
This user's guide contains all of the information you need to connect the USB-3105 to your computer and to the
signals you want to control. The USB-3105 is part of the Measurement Computing brand of USB-based data
acquisition products.
The USB-3105 is a USB 2.0 full-speed device that is supported under popular Microsoft®Windows®operating
systems. The USB-3105 is fully compatible with both USB 1.1 and USB 2.0 ports.
The USB-3105 provides 16 channels of analog voltage output, eight digital I/O connections, and one 32-bit
event counter.
The USB-3105 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 analog outputs may be updated individually or simultaneously.
A bidirectional synchronization connection allows you to simultaneously update the DAC outputs on multiple
devices.
The USB-3105 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-3105 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-3105.

Installing the USB-3105
Unpacking
As with any electronic device, you should take care while handling to avoid damage from static
electricity. Before removing the device from its packaging, ground yourself using a wrist strap or by simply
touching the computer chassis or other grounded object to eliminate any stored static charge.
Contact us immediately if any components are missing or damaged.
Installing the software
Refer to the MCC DAQ Quick Start and the USB-3105 product page on our website for information about the
software supported by the USB-3105.
Install the software before you install your device
The driver needed to run the USB-3105 is installed with the software. Therefore, you need to install the
software package you plan to use before you install the hardware.
Installing the hardware
To connect the USB-3105 to your system, connect the USB cable to an available USB port on the computer or
to an external USB hub connected to the computer. Connect the other end of the USB cable to the USB
connector on the device. No external power is required.
When connected 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. The Status LED on the USB-3105 turns on after
the device is successfully installed.
If the Power LED turns off
If communication is lost between the device and the computer, the device LED turns off. To restore
communication, disconnect the USB cable from the computer and then reconnect it. This should restore
communication, and the LED should turn on.
Calibrating the hardware
The Measurement Computing Manufacturing Test department performs the initial factory calibration. Return
the device to Measurement Computing Corporation when calibration is required. The recommended calibration
interval is one year.

Figure 5. USB-3105 signal pinout
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 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 Figure 6. 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).

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 Help 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-3105 and simultaneously update the
DAC outputs on each device. Refer to Synchronizing multiple units on page 13.
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).
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-3105 and possibly the computer.

USB-3105 User's Guide Functional Details
13
Synchronizing multiple units
You can connect the SYNCLD terminal pin (pin 49) of two USB-3105 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-3105 to the SYNCLD pin of the slave USB-3105.
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.
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 1: The USB-3105 output voltage level defaults to 0V whenever the output voltage range is reconfigured.
The USB-3105 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 2: The duration of this output transient is highly dependent on the enumeration process of the host PC. Typically
the output of the USB-3105 is stable after 2 seconds.
