ISO-DONGLE1Z
1.
Functional Description
The ISO-DONGLE1Z is shown in
cable. The button on the board, labeled SW1, resets the MCU on the dongle. Pressing this button is occasionally
necessary when an unexpected error occurs either on the evaluation board side, such as a loss of power during
communication, or a crash on the PC side. Disconnecting the dongle from the evaluation board and the PC also
resets the dongle MCU.
The user's manual for all Renesas BMS GUIs provides additional information on the steps required to use the
dongle to communicate between a target GUI and evaluation kit. Most evaluation boards should be powered
before the dongle is connected.
