Preface About this User’s Guide What you will learn from this user's guide This user's guide describes the Measurement Computing USB-3105 data acquisition board and lists hardware specifications. Conventions in this user's guide For more information Text presented in a box signifies additional information related to the subject matter.
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.
Chapter 2 Installing the USB-3105 What comes with your USB-3105 shipment? The following items are shipped with the USB-3105. Hardware USB-3105 device USB cable (2 meter length) Additional documentation In addition to this hardware user's guide, you should also receive the Quick Start Guide (available in PDF at www.mccdaq.com/PDFs/manuals/DAQ-Software-Quick-Start.pdf).
Fax: 508-946-9500 to the attention of Tech Support Email: techsupport@mccdaq.com Installing the software Refer to the Quick Start Guide for instructions on installing the software on the Measurement Computing www.mccdaq.com/PDFs/manuals/DAQ- Data Acquisition Software CD. This booklet is available in PDF at Software-Quick-Start.pdf. Installing the hardware Be sure you are using the latest system software Before you connect the USB-3105, make sure that you are using the latest versions of the USB drivers.
LED should turn back on. Calibrating the USB-3105 The USB-3105 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.
Chapter 3 Functional Details External components The USB-3105 has the following external components, as shown in Figure 3. USB connector Status LED Power LED Screw terminal banks (2) Screw terminal pins 29 to 56 Status LED Power LED Screw terminal pins 1 to 28...
USB-3105 User's Guide Functional Details Screw terminal banks The USB-3105 has two rows of screw terminals—one row on the top edge of the housing, and one row on the bottom edge. Each row has 28 connections. Use 16 AWG to 30 AWG wire gauge when making screw terminal connections.
USB-3105 User's Guide Functional Details Figure 5. USB-3105 signal pin out Analog voltage output terminals (VOUT0 to VOUT15) The screw terminal pins labeled VOUT0 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 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.
USB-3105 User's Guide Functional Details Power terminal (+5V) connection (pin 56) draws power from the USB connector. This terminal is a +5V output. +5 V 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 Specifications The duration of this particular output transient is highly dependent on the enumeration process of Note 2: the host PC. Typically the output of the USB-3105 is stable after 2 seconds. The maximum differential non-linearity specification applies to the entire 0 to 70 °C temperature Note 3: range of the USB-3105.
USB-3105 User's Guide Specifications Pull up and pull down configuration area available using the DIO CTL terminal block pin 54. The Note 4: pull down configuration requires the DIO CTL pin (pin 54) to be connected to a DGND pin (pin 50, 53 or 55).
