TMP122EVM (EValuation Module)
INSTALLATION
To install the TMP122EVM, simply unpack it and plug it into a 9-pin RS-232 port. You can connect it to an
RS-232 cable, as long as the cable carries the proper conductors. Note that this EVM requires the serial
port of the PC to supply signals at the +/-12V level. Some PCs have 3.2V serial ports. The EVM will not
work with these PCs.
WINDOWS SOFTWARE INSTALLATION
To install the Windows version of the software use Windows Explorer to locate the TMP122 folder on the
CD. Double click on the setup.exe and follow the on screen instructions.
SOFTWARE OPERATION
The TMP122 evaluation software functions as a simple digital thermometer. Each feature of the TMP122
can be exercised using the program. When the program is run, it scans the system to see what serial ports
are available. If it finds at least one, it searches each serial port for a TMP122EVM, and uses the first one it
finds. If the program does not find any TMP122EVMs, it displays a warning message.
This screen has several areas of interest:
? Near the top left corner of the window is the area that allows the user to control the plot function.
? Below that is the area that displays information based on the cursor location.
? The contents of the measured temperature register are displayed next. User can toggle between
Celsius or Fahrenheit by simply clicking on (Deg C) or (Deg F) above the actual display
? Tthe contents of the configuration register are shown in the last panel. User can change those values by
simply typing the appropriate bit values in the appropriate bits and pressing ENTER. If user positions
cursor over the label for a certain bit an explanation of that bit function will appear in the information
panel above.
