DS1701K Datasheet, PDF (2/9 Pages) Dallas Semiconductor – 1-Wire Thermal Device Evaluation Kit

DS1701K
INTRODUCTION
The DS1701K evaluation kit makes performance evaluation, software development, and prototyping with
the Dallas 1-Wire thermal devices easy. The evaluation board interfaces to PC through a DS9123 serial
port adapter and RJ-11 cable connection. The provided CD-ROM contains all related data sheets along
with the evaluation software, which can be run under Windows 95 or newer.
The DS1701K evaluation software gives the user complete control of all functions of the Dallas 1-Wire
thermal devices. Separate control tabs allow the user to view the real-time updates of the temperature at
the desired resolution as well as access to all scratchpad and EEPROM memory locations. The software
incorporates a datalogging feature to monitor a device over time. Additionally the software provides the
ability to select and read various devices on the 1-Wire bus.
SETUP AND INSTALLATION
BOARD CONNECTIONS
The Dallas 1-Wire thermal devices can be placed in any or all of the X1 through X5 3-pin sockets and be
soldered into any or all of the U1 through U5 holes. The user can install up to 10 devices on the 1-Wire
bus on this evaluation board and then use the software to select which device to read. See the Device
Select Menu section below. However, make sure there is a maximum of one DS1821 on the bus, because
the DS1821 does not offer the multidrop functionality and will create data collisions if more than one is
on the bus at a time.
Communication to the board can be accomplished by connecting the DS9123 serial port adapter to an
available serial port on a PC. Then connect the RJ-11 jack to the DS9123 serial port adapter with the
provided 6 conductor cable. The DS1701K software can communicate with the Dallas 1-Wire thermal
devices without a power supply being connected to the board. However, temperature readings will not be
performed unless the device is configured in parasite power mode (see device data sheets for information
on parasite power mode.)
SOFTWARE INSTALLATION
To install the DS1701K software, exit all programs currently running and insert the DS1701K software
CD into your computer’s CD-ROM. The user can run SETUP.EXE from the setup directory and the
installation process begins. Follow the prompts to complete the installation. The DS1701K software can
be uninstalled in the Add/Remove Programs tool in the Control Panel. After the installation is complete,
open the DS1701K folder and run DS1701K.EXE or select DS1701K from the program menu. A splash
screen containing information about the evaluation kit appears as the program is being loaded.
The documentation directory, also located on the CD, contains all relevant data sheets and application
notes on the DS18B20, DS18S20, DS1821, DS1822, and DS1701K. They are stored in Adobe Acrobat
format for easy viewing.
