USB-SMBUS-CABLEZ, usb-5psmbus-cablez rev. 0 | page 2 of 4 evaluation board software driver installation version 4.0.0 or later of the adm1062 to adm1069 evaluation software or version 3.0.0 of the adm1175/adm1176/adm1177/ adm1178 and adm119x evaluation software provides the necessary software support for the usb-to-i 2 c interface dongle. to install the driver software, perform the following steps: 1. install the evaluation software before the cable is plugged in. if prompted by the software, restart the pc. 2. plug the cable into a free usb port on the pc. the operating system recognizes that a new device has been attached and asks if you want to install new drivers for it. 3. select the default option, which is to let the operating system locate the drivers for you, and click continue to search for the drivers. depending on your pc settings, you may also be prompted that the driver you are installing is unsigned. click continue anyway if prompted to complete the driver installation. the cable is now ready for use. note that on certain pc configurations you will be prompted to install the drivers the first time you plug the cable into each of the usb ports on the pc. once this installation is complete for a port, it does not need to be repeated. for more information on these devices and to download the evaluation software, visit www.analog.com . warning when using a usb-to-i 2 c interface dongle with the adm1062 to adm1069 evaluation board (eval-adm106xeb), the evaluation board power must be turned on before connecting the dongle to the 3-pin header on the board. if this is not done, damage to either the dongle and/or evaluation board may result.
