Parallel Port to I
2
C Interface Cables
CABLE-SMBUS-3PINZ, CABLE-SMBUS-5PINZ
GENERAL DESCRIPTION
This data sheet provides details of the parallel port to the I
2
C®
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 I
2
C device using the
appropriate PC software. Note that a suitable power supply must
also be provided to the device.
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.
