4.1.2 Host Interface

The 6-pin J3 - Serial connector is used to connect the bq76PL455EVM to a PC running the GUI or to a host controller. Signals at the J3 - Serial connector are 5-V TTL signals. Texas Instruments recommends using FTDI’s USB-to-TTL serial converter cable to allow connection with a PC’s USB port. The recommended cable is available from FTDI (http://www.ftdichip.com), and the appropriate part number for the 1.8-meter cable is TTL-232R-5V.
