This EV sys - tem provides the special hardware and software system to exercise the features of 1-Wire devices with memory or PIO/switches, except 1-Wire EPROM devices. (EPROM devices such as the DS2502 and DS2506 require a dif - ferent adapter (DS9481R-3C7) to perform an EPROM write. This adapter can be purchased separately.) 1-Wire EPROM devices are available for sampling. The EV system software consists of the OneWireViewer (a Java ® program) that runs under Windows ® OS and comes as part of the 1-Wire drivers installation package. Benefits and Features
- Easy Setup with USB Adapter
- Fully Compliant with USB 2.0 Specification
- Software Runs on Windows 8, Windows 7, Windows Vista®, and Windows XP® OS (32-Bit and 64-Bit Versions)
- Convenient On-Board Test Points and Dual TO92 Socket
- Standard RJ11 Connector Interfaces to DS9120 Socket Boards
- Free Download of 1-Wire Drivers and OneWireViewer Demonstration Software
- Compatible with Other 1-Wire Devices Purchased Separately 19-7527; Rev 1; 4/16 Ordering Information appears at end of data sheet. 1-Wire and iButton are registered trademarks of Maxim Integrated Products, Inc.

1 DS9120P+ Socket board (Dual TSOC and
TO92)
1 DS9490R# 1-Wire USB adapter with RJ11
3 DS2401P+ 64-bit silicon serial number
(3 TO92)
3 DS2406P+ 1-Wire, dual-addressable switch
3 DS2411P+ Silicon serial number with VCC input

3 DS2431P+ 1024-bit 1-Wire EEPROM
3 DS24B33+ 1-Wire 4Kb EEPROM
3 DS28E07P+ 1024-bit 1-Wire EEPROM
1 Cable RJ11 male to RJ11 male cable
a part placed into the DS9120P+ socket.
- Select the 1-Wire device to evaluate and insert it into the appropriate socket, ensuring it is properly orient- ed. Jumper the appropriate enable pins for the TSOC socket. See the DS9090EVKIT Setup section for help.
- Run the OneWireViewer. If any difficulty is en- countered, see the Troubleshooting Guide section. Another helpful resource is Application Note 3358: OneWireViewer User’s Guide. The OneWireViewer presents a Device List window located on the left-hand side of the main screen. It dis - plays a list of the different 1-Wire devices found con - nected to the DS9490R#. The 1-Wire device type inserted into the socket or header of the evaluation board should be shown in the Device List window, along with the 64-bit ROM ID lasered into the device. Figure 8 shows the DS1972 in the Device List window, along with its 64-bit ROM ID value of DC000002A0BC322D.
- From the Device List window, select the part by clicking on it.
- Once the 1-Wire device has been selected, the right- hand side of the main OneWireViewer screen is populated with different tabs. There are at least three tabs for each device contained in the DS9090EVKIT: Description, Memory, and File. A fourth tab labeled Switch is also available on those parts containing switches.
- Clicking on the Memory tab brings up the Memory Viewer. The user has the choice of reading/writing any of the memory banks listed in the Banks section of the Memory Viewer. When done editing the raw page (en- tering in a hexadecimal number for each byte), press Commit Changes to write to the memory.
- Click the Commit Changes button to write the changes to the device memory.
- Clicking Refresh rereads the contents of the 1-Wire memory.
- The File tab allows writing files to the device’s memory. To do this, the user needs to first Format the Device, then Create/Read/Write/Delete files and directories.
- The Switch tab allows reading and toggling of the PIO pin states and clearing of activity latches. Refer to Application Note 3358 for further instructions on how to use the many features of the OneWireViewer.
