USB-to-I2C Interface Dongles USB-SMBUS-CABLEZ, USB-5PSMBUS-CABLEZ GENERAL DESCRIPTION This data sheet provides details of the USB-to-I2C® interface dongles. The USB-SMBUS-CABLEZ is a 3-pin version designed for use with the ADM1062/ADM1063/ADM1064/ADM1065/ ADM1066/ADM1067/ADM1068/ADM1069 (hereafter referred to as ADM1062 to ADM1069) family of programmable super sequencers. The USB-5PSMBUS-CABLEZ is a 5-pin version for use with the ADM1175/ADM1176/ADM1177/ADM1178 family of hot swap controllers and ADM1191x power monitoring devices. The dongles are designed to connect a standard PC or notebook USB port to a 3-pin or 5-pin header on an evaluation board, system board, or preprogramming module. The dongles can SCL SDA GND SCL SDA GND 3-PIN HEADER ON ADM1062 TO ADM1069 EVALUATION BOARD then be used to access and program a supported I2C device using the appropriate PC software. Note that a suitable power supply must also be provided to the device. Both dongles provide clock (SCL), data (SDA), and GND signals. The USB-5PSMBUS-CABLEZ also provides a CONV and an ALERT signal. The signals are labeled on the crimp housing of the cable. It is advisable to mark Pin 1 of the header on the board to ensure correct orientation upon connection, as shown in Figure 1. Figure 2 shows the schematic for the PCB contained in the USB port dongle. The schematic is the same for the USB-SMBUS-CABLEZ and the USB-5PSMBUS-CABLEZ.

USB-SMBUS-CABLEZ, USB-5PSMBUS-CABLEZ 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-I2C interface dongle. To install the driver software, perform the following steps: 1. 2. 3. Install the evaluation software before the cable is plugged in. If prompted by the software, restart the PC. 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. 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-I2C 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. Rev. 0 | Page 2 of 4 Figure 2.
