Software Drivers
An FTDI FT232R USB-to-UART adapter driver is required to connect to the passive balancing evaluation
module to a PC. The driver is either installed automatically as part of the cable install when installing the
TTL-232R-5V from FTDI, or download it from
www.ftdichip.com/Drivers/VCP.htm
.
