DS9090EVKIT
Evaluation System
Quick Start
Required Equipment
●DS9490R# USB-to-1-Wire/iButton adapter (included)
●DS9120P+ socket adapter (included)
●Computer with a Windows 8, Windows 7, Windows
Vista, or Windows XP operating system (32-bit or 64-
bit) and a spare USB 2.0 or higher port
●TSOC or TO92 parts (included)
●OneWireViewer software with bundled drivers

refers to items from the Windows operating system.
DS9090EVKIT Setup
Procedure
1) Install the 1-Wire drivers. See the Installing the
DS9490R# and 1-Wire Drivers section for instructions.
2) DS9120P+ jumper settings:
a) Remove jumpers from the JB1 to leave only the
middle three jumpers connected. See Figure 4.
b) 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. When using the DS2413P
in socket S1, the user can populate R3 and R4
with 10kΩ pullups; otherwise, these need to
be added externally. PIOA can be observed on
J3:1 and PIOB can be observed on J3:5. See
Figure 9 for resistor and pin location.
c) Note that when evaluating a DS2411P device,
is necessary to place a jumper to 3.3V and a
wire must be soldered to jump R3 and R5. See
Figure 5.
Note: Refer to the DS9120P and each device IC
data sheet for complete schematic and pin input and
output to confirm proper operation for each device to
be evaluated.
3) Insert the DS9490R# into a spare USB port of
the PC. Only after OneWire Drivers Installation is
completed should the DS9490R# be inserted. Once
inserted, wait for the operating system to complete
the plug-and-play process. For Windows 2003
and XP (SP2), the OS prompts about installing the
DS9490R# device with the Add Hardware wizard
before continuing. Newer operating systems com-
plete the plug-and-play process without the wizard.
During the installation process, the drivers are set
up to point to the USB adapter as the default port
type and port 1 (USB1) as the default port number.
The default port type and number settings can be
changed at any time after installation by running the
Default 1-Wire Net program that is installed with
the drivers. To do so, simply click on Start | Pro-
grams | 1-Wire Drivers xXX (xXX represents the
OS architecture, either x86 or x64). Then click on
the icon labeled Default 1-Wire Net. If problems are
encountered during installation, refer to Application
Note 1740: White Paper 6: 1-Wire Drivers Installa-
tion Guide for Windows, specifically the “Appendix
A: 1-Wire USB Adapter (DS9490) Installation Help”
section.
4) Connect the DS9120P+ to the DS9490R# with the
supplied RJ11-to-RJ11 cable. One end of the cable
should be plugged into the DS9120P+ board and the
other end into the DS9490R#. See Figure 6.
5) Insert the 1-Wire device of interest into the
DS9120P+ socket. See Figure 7 for proper chip
orientation.
Run the OneWireViewer.
Click on Start | Programs | 1-Wire Drivers xXX.
Then click on the OneWireViewer icon. This runs
the OneWireViewer. If the OneWireViewer cannot
find a suitable Java Runtime Environment (JRE), it
prompts the user with a message to download the
latest one from www.java.com. Once the
OneWireViewer is running, the 64-bit ROM ID values
(i.e., the 1-Wire network addresses) of all 1-Wire
chips inserted into the evaluation board are dis-
played. Clicking on the chip’s address selects the
chip and starts communicating with it. The OneWire-
Viewer then makes other tabs available that contain
functionality to exercise the chip (i.e., read and write
data, files, exercise PIO pins, etc.). It is also possible
to run the OneWireViewer on OS platforms other
than Windows, but it could require special setup and/
or additional software installation. Refer to the
OneWireViewer website for more information at
www.maximintegrated.com/onewireviewer.
6) When properly installed, the follow GUI should ap-
pear as shown in Figure 8.
