bq4050EVM Quick Start Guide
This section provides the step-by-step procedures required to take a new EVM and configure it for
operation in a laboratory environment.
2.1
Items Needed for EVM Setup and Evaluation
The following items are required for setup and evaluation:
•
bq4050 circuit module
•
EV2300 or EV2400 communications interface adapter
•
USB cable to the communications interface adapter to the computer
•
Computer setup with Windows XP or higher operating system
•
Access to the internet to download bqStudio software setup program
•
One-to-four battery cells or 1-k
Ω
resistors to configure a cell simulator
•
DC power supply that can supply 16.8 V and 2 A. (Constant current and constant voltage capability is
desirable.)
2.2
System Requirements
The bqStudio software requires Windows XP or later. Using later versions of Windows operating system
can have issues with the USB driver support. The EV2300 USB drivers have been tested for Windows
98SE, but no assurance is made for problem-free operation with specific system configurations.
2.3
Software Installation
Find the latest software version of bqStudio on
http://www.ti.com/tool/bqstudio
. Search by part number for
bq4050 to access the tool folder for the device. Use the following steps to install bq4050 bqStudio
software.
1. Ensure that the EV2300 or EV2400 is not connected to the personal computer (PC) through the USB
cable before starting this procedure.
2. Open the archive containing the installation package and copy its contents into a temporary directory.
3. Open the bqStudio installer file that was downloaded from the TI Web site.
4. Follow the on-screen instructions until completing the software installation.
5. Before starting the evaluation software, connect the EV2300 or EV2400 to the computer using the USB
cable.
6. If EV2300 is connected, wait until the system prompt
New Hardware Found
appears. Choose
Select
Location Manually
and use the
Browse
button to point to subdirectory TIUSBWin2K-XP-1.
7. Answer
Continue
to the warning that drivers are not certified with Microsoft.
8. If the EV2300 is connected, after the previous installation finishes, another system prompt
New
Hardware Found
appears. Repeat steps 1 through 5, but specify the directory as TIUSBWin2K-XP-2.
9. Answer
Continue
to the warning that drivers are not certified with Microsoft. Driver installation is now
finished.
10. For the EV2400, the driver should be installed along with software installation.
2.4
Troubleshooting Unexpected Dialog Boxes
The user downloading the files must be logged in as the administrator. The driver is not signed, so the
administrator must allow installation of unsigned drivers in the operating system. If using Windows 7,
install the software with administrator privileges.
2.5
EVM Connections
The bq4050 evaluation system comprises three hardware components: (1) the bq4050 circuit module, (2)
the EV2300 or EV2400 PC interface board, and (3) the PC.
