DS1615K/DS1616K Temperature/Data Recorder Evaluation Kit www.dalsemi.com DESCRIPTION The DS1615K and DS1616K are designed to demonstrate, exercise, and control the features of the DS1615 Temperature Recorder or DS1616 Temperature and 3-Input Data Recorder. In addition, these kits can also be used to program the registers, memory, date, alarm, and trip points of both devices. As shown in Figures 1 and 2, the evaluation board includes a DS1615 or DS1616 integrated circuit, support components, and connectors. The kit also comes with an RS-232 cable, and media containing the documentation and software to operate the kit and design with the DS1615. The DS1615K may be used in a Windows95/98 or NT environment. The Latest revision kit software and source code in Microsoft Visual C++ are available on the Dallas FTP site: ftp://ftp.dalsemi.com/pub/datalogging/. Figure 1. DS1615 Evaluation Board Figure 2.

Click on the “Start” button or press the windows “Start” key on the keyboard. 2. From the “Start” command box choose “Run…” 3. From the “Run…” command box type A: Setup (or the appropriate drive letter) and choose “OK.” This will start the “Setup Wizard”. 4. Press the “Next” button to continue the installation. 5. The “Setup Wizard” will pick the default directory to locate this program as a sub-directory of the “Programs” directory. To use the default click the “Next” button or select a different directory and click the “Next” button. 6. You will then have a chance to review all of the information that you have selected. Click the “Next” button to begin loading files from the disk drive. 7. For floppy disk installation, when requested to do so, replace Disk 1 with Disk 2 and click “OK”. This will complete the software installation and will create an icon on your desktop. 8. A screen may appear telling you that one or more .dll files have not self-registered. This is not a problem. Your system already contained the required files so the copy provided was not used. The program will operate correctly with the files already installed on your system. NOTE: All of the available documentation for the DS1615, and DS1616, the evaluation kits and application note 116 are available on the Dallas Semiconductor web site at: http:/www.dalsemi.com/DocControl/index.html. COMMUNICATION WITH PC In order for the evaluation kit to communicate with your PC, you must connect the evaluation kit board to a free serial port with the included serial port cable. The cable has a standard 9-pin DB9 connector. If your system is equipped with a 25-pin connector, you can purchase a 25-pin to 9-pin adapter at most computer stores. When the software is run, a dialog box will request the user to specify which serial port is connected to the evaluation board. Many laptop PCs do not have the required 5 volt minimum output from the RS-232 port to power the evaluation board and therefore will not communicate with the evaluation kits. With less than 5 volts to power the board, the regulated Vcc level never exceeds the 4 volt threshold for communications. One way around this problem is to disconnect the Vdrive_in circuit from pin 4 of the RS-232 connector which will isolate the Vdrive_In circuit from the RS-232 port of the PC. This signal will normally be used to power the evaluation board. If the Vdrive_In circuit is then connected to the positive terminal of a 9-volt battery or other power supply of greater than 5-volt, the device will work without a problem, as long as the power source is connected prior to initiating any RS-232 communications. If the PC tries to communicate with the board while the power source in not connected or less than 5 volts, the RS-232 driver on the board may latch-up. The power source is only required for communication with the board. All other board functions can be supplied by the 3.6 volt battery on the board itself. 2 of 6 DS1615K / DS1616K EVALUATION BOARD CONFIGURATION The DS1615 or DS1616 evaluation board may be configured for synchronous or asynchronous communications. Note: The kit software provides for asynchronous communications only. The asynchronous option is internally selected automatically with a pulldown resistor inside the chip itself. The software included with this kit was developed to communicate with the evaluation board over an asynchronous, RS-232 serial port. To select asynchronous communication, pins 2 and 3 on jumper JP1 should be shorted together. To select synchronous communication, short pins 1 and 2 together. When synchronous communication is selected, interfacing with the device is facilitated by the SCLK, I/O, and RST# pins which are available on jumper JP2. The board will require 5-volt power when using the synchronous communications just like when using the RS-232, but there is no ability to steal the power from the incoming signal lines as was done with the RS-232. For this reason, 5 volt must be applied to the board either through pin 4 of the RS-232 connector set to 5 volt or greater, or pin 1 of the 5 volt regulator. Future revisions of the board will have a Vin pin on the J2 header with the 3-wire signal lines. Consult the datasheet for the functionality of these pins.
