Parallel Port to I2C Interface Cables CABLE-SMBUS-3PINZ, CABLE-SMBUS-5PINZ GENERAL DESCRIPTION This data sheet provides details of the parallel port to the I2C® interface cables. The CABLE-SMBUS-3PINZ is for use with the ADM106x series of programmable power supply sequencers from Analog Devices, Inc. The CABLE-SMBUS-5PINZ is for use with the ADM1175/ADM1176/ADM1177/ADM1178 family of hot swap controllers and ADM119x power monitoring devices. The dongles are designed to connect a standard PC or notebook parallel port to a 3-pin or 5-pin header on an evaluation board, system board, or preprogramming module. The dongle can 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. SCL SCL SDA SDA GND GND 3-PIN HEADER ON ADM106x EVALUATION BOARD 3-TERMINAL CRIMP HOUSING Both cables provide clock (SCL), data (SDA), and GND signals. The CABLE-SMBUS-5PINZ 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 a schematic for the PCB contained in the parallel port connector for the CABLE-SMBUS-3PINZ. Figure 3 shows a schematic for the PCB contained in the parallel port connector for the CABLE-SMBUS-5PINZ.
