Socket Boards for Evaluating 1-Wire Devices
Evaluates: DS9120
General Description
Features
The DS9120 family of socket boards are RJ11-to-socket
boards that provide the hardware connectivity necessary
to evaluate and operate 1-Wire products in an easy-to-
use PC environment. Additionally, the socket boards can
be readily used with the DS9481R USB-to1-Wire adapter
to create a 1-Wire PC programmer for 1-Wire EEPROM
and one-time programmable (OTP)/EPROM devices.

1-Wire Socket Boards
The DS9120 family of 1-Wire socket boards are 1-Wire
accessories that support 1-Wire EEPROM, EPROM, and
ROM devices for different packages. See the Ordering
Information table to determine which socket board is
available for each package type. All socket boards
include the socket and RJ11 cable assembly (see the
Socket Board Contents List (Included with Each Order))
table for the complete list).
RJ11 Pinout
Table 1 shows the RJ11 pinout at RJ1 mounted on each
DS9120 socket board. This also matches the RJ11 pinout
for the DS9481R. RJ11 pin 1 can supply 3.3V and can
be used for auxiliary board power. GND is ground of
the 3.3V supply. The signal OW (DATA) stands for the
1-Wire data bus. The ground return for OW (DATA) is the
signal OWGND. The PULSE signal is to be used as the
DS9120P Jumper Settings
The DS9120P socket board for the TSOC package
requires jumpers for communication. The only reason for
these jumpers is for debugging, or to break out the RJ11
signals. Set the jumpers as shown in Figure 1 for parasiti-
cally powered devices, and set the jumpers as shown in
Figure 2 for nonparasitically powered devices.

CC
power supply for OTP EPROM memory devices. The
PULSE signal is typically 3.3V, but can also provide the
needed programming pulse for 7V OTP EPROM memory
devices. The GP signal is reserved for future general-pur-
pose use and is functionally not used by the DS9481R.
Table 1. 1-Wire RJ11 Pinout
Additionally, note that when evaluating a DS2413P
device, jumpers J1 and J4 are to be populated. For all
other 1-Wire slave devices, do not populate J1 or J4 with
a jumper.
