Advanced bqMTester Instructions
The driver installation process of each instance of the EV2x00 boards should only be done one time. After
the initial installation, the only reason it would be required to repeat the process is if the orientation
between the USB ports and EV2x00 boards changes. This could happen if a USB hub position is
changed, a USB hub is installed, or if an additional EV2x00 is installed. USB hubs can be used to
accommodate stations for the bqMTester.

NOTE:
It is recommended not to exceed seven EV2x00/Test Stations per USB hub, and USB hubs
cannot be nested. Stations will not install with nested USB hubs. It is also recommended that
the USB hub be USB 2.0-compliant and capable of 1.0 A of output current. Operating power
for each EV2x00 is supplied by the hub.

Station Hardware Connections
The bqMTester requires that the latest version of the EV2x00 interface from Texas Instruments be
installed and running properly. These instructions explain connecting an HPA495 bqMTester board.

CAUTION
It is very important that the two ground connections connected to 1N of the
module under test be connected as close to the BAT

CAUTION
It is very important that these power supplies be ground isolated. There should
be no ground plug on the wall connection. An example of good supplies are:
