1-Wire Device Evaluation Kit
8Pages

The DS9090K provides the hardware and software necessary to evaluate and operate 1-Wire > QTYDESCRIPTION products in an easy-to-use PC environment. All 1-Wire EEPROM, EPROM*, and ROM devices are readable with the DS9090K. All 1-Wire devices with memory or PIO/switches can be written with the DS9090K except 1-Wire EPROM devices*. In this way, the engineer can evaluate 1-Wire chips for potential design purposes or support end-product development activity. Kit operation requires a host PC. Demonstration software consists of the OneWireViewer (a JavaΙ program). For 32-bit and 64-bit Windows operating systems, the OneWireViewer comes as part of the 1-Wire Drivers install package. For other operating systems, refer to the online version of the OneWireViewer. 1 PCB: 1-Wire Device Evaluation Board 1 RJ11 male to RJ11 male cable, 7ft 11-Wire USB adapter with RJ11 Maxim DS9490R# 164-bit silicon serial number (3-pin TO92) Maxim DS2401+ 11-Wire addressable switch (6-pin TSOC) Maxim DS2405P+ 11-Wire dual-addressable switch plus 1kb EPROM memory (6-pin TSOC) Maxim DS2406P+ 11-Wire dual-channel addressable switch (6-pin TSOC) Maxim DS2413P+ 11024-bit 1-Wire EEPROM (3-pin TO92) Maxim DS2431+ > PART TYPE 14Kb 1-Wire EEPROM (3-pin PR-35) Maxim DS2433+ DS9090K# EV kit > # Denotes a RoHS-compliant device that may include lead that is exempt under the RoHS requirements 14096-Bit Addressable 1-Wire EEPROM with PIO (on EV kit) Maxim DS28E04S-100+ > . 120Kb 1-Wire EEPROM (3-pin TO92) Maxim DS28EC20+ > IBM-Compatible PC Running Windows Vistaή, Windows XP SP2, 2003, or 2008 1 Package of 11 2-pin shunts for jumpering Spare USB Port on the PC > *EPROM devices, such as the DS2502, DS2506, etc., requireadifferent adapter (DS9097U-E25) to perform an EPROM write. This adapter can be purchased separately and requires a +12 V p ower supply and a 2 5 -pin to 9-pin serial port adapter (refer tothe adapters data sheet for details). 1-Wire EPROM devices are available to be sampled (up to quantity 2). 1-Wire is a registered trademark of Dallas Semiconductor Corp., a wholly owned subsidiary of Maxim Integrated Products.

Note: In the following sections, software-related items are identified by bolding. Text in bold refers to items directly from the EV kit software. Text in bold and underlined refers to items from the Windows operating system. > The DS9090K comes standard with a USB-to-1-Wire adapter (DS9490R). It is advisable to connect the USB end of the adapter to a free USB port after the installation of the software drivers has completed (see the SoftwareInstallation section). Connect the evaluation board to the PC with the supplied RJ11 to RJ11 cable. One end of the cable should be plugged into the...

A section of the evaluation board is dedicated to demonstrating the DS28E04-100 1-Wire chip. Before experimenting with the DS28E04-100, the circuits enable pins, J2, must be jumpered (see Figure 1). This jumpers the DS28E04-100 onto the 1-Wire bus, allowing the 1-Wire software to communicate with the device. Note the row of header pins at the bottom of the circuit, several of which can be jumpered. The pins labeled A0ҖA6 correspond to the seven address inputs that can be jumpered to modify a portion of the 1-Wire network address of the device. Other pins available are VCC, POL, and the PIO...

DS9090K 1-Wire Device Evaluation Kit www.maxim-ic.com/onewireviewer . > Select the 1-Wire device to evaluate and insert it into the appropriate socket, making sure it is properly oriented. Jumper the appropriate enable pins for the TSOC socket (J5) and/or the DS28E04-100 evaluation circuit (J2). See the Hardware Installation section for help. Finally, connect the evaluation board to the PC. Run the OneWireViewer . If any difficulty is encountered, see the Troubleshooting Guide section. Another helpful resource is the OneWireViewer Users Guide , which is available on our website at...

SYMPTOM POSSIBLE CAUSE CORRECTIVE ACTION Operating system prompt giving installation error.Cause: The 1-Wire adapters device driver did not get installed properly. Refer to White Paper 6: 1-Wire Drivers Installation Guide for Windows , specifically the ғAppendix A: 1-Wire USB Adapter (DS9490) Installation Help section. Cannot communicate through 1-Wire adapter. Cause 3: The adapter type selected is not what is connected. Run the Cause 1: The PC port hardware is not functioning properly. Does the port work with other applications, such as a keyboard or mouse? If not, contact the motherboard...
