K145 Temperature
Monitor Lite
(shareware,
$19 USD)
This application is designed to monitor and display temperature information from the
DIY/Kitsrus K145 Temperature Data Logger kit
(www.kitsrus.com). This is a 4 – channel unit, using DS18S20 one-wire temperature sensors. Connection to the pc is through the serial port.

Change Log
Dec 14/09
v. 2.0.1 (08)
- added user-configurable diagram interface
- create diagram in separate Diagram Editor program
- plot display is moved to diagram page, and
reduced in height
- capture function
- plot and diagram together
- plot only
- added ability to add user comments to Log
- revised configuration display
- revised time display at bottom of main window
- this (diagram capable) version becomes shareware
- Help file updated
Oct 17/09
v. 1.7.0 (79)
- added ability to modify recorded (and displayed) temperatures
with a calibration offset value.
- Help file updated.
Mar 26/09
v. 1.6.6 (76)
- fixed issue with Spacebar key, where pressing the Spacebar
could accidentally cause a connect/disconnect from the K145
Mar 09/09
v. 1.6.5 (75)
- fixed problem with Logging engine where logging
would stop for no apparent reason.
Jan 28/09
v. 1.6.4 (73)
- fix bug in auto-save Log counter
- fix bug in how Min/Max values are handled.
Originally, the Min/Max values would be immediately reset
if piece of "bad data" came through on that channel.
Now, previous Min/Max values are maintained. Min/Max values
are reset only when establishing a connection with the K145
board,
when changing temperature scale, or by deliberate
manual action.
- modified temperature display handling.
Originally, if a piece of bad data came through, that channel
display would be immediately set to "-----". Depending on the
severity of the problem, that channel display might be seen to
be flipping back and forth between "-----" and a number.
Now, the display for that channel will maintain the previous value
when a piece of bad data comes through. This is on a 10-second
timeout. If valid data hasn't arrived within the timeout period, the
the display will go to "-----".
- Help file updated
Jan 21/09
v. 1.6.3 (71)
- fix bug in auto-saving the Log
- modified internal handling of data errors
Known issue: the Min/Max values for a given channel may reset
if a piece of "bad data" comes through on that channel.
Jan 12/09
v. 1.6.2 (70)
- fixed problem with sign not being displayed for negative temperatures
- improved timing accuracy of the logging engine
Nov 27/08
v. 1.6.1 (63)
- added options for handling data errors
This is useful for older hardware where data transmission
may not be stable.
- Log is now automatically saved to file every 24hr
- Added a counter to display how many times the Log has been auto-saved
- revised form layout so that current temperatures are
visible no matter which page is displayed
- removed the visual Tabs that were used to switch between views.
Instead, use the shortcut keys (or the popup
menu)
- [Ctrl] + [T] for Thermometers
- [Ctrl] + [P] for the Plot page
- [Ctrl] + [L] for the Log page
- Thermometer page is now called "Thermometers" rather than "Display"
in the popup menu.
Shortcut key changed to [Ctrl] + [T]
- Config and Log files are now stored in a subfolder of the MyDocuments
folder. ie: C:\MyDocuments\K145\K145Config.ini
- updated the Help file
Known issue...
Under certain conditions, the timing of Log entries gradually shifts.
This is apparent in Win98 systems, and in newer systems with multiple
processors. Example: over a 24hr period, the Log timestamps may have
gained (or lost) approximately 5 seconds.

Notes:
a. This version of the Temperature
Monitor is freeware.
b. Read about the DS18S20 1-wire Temperature Sensor here.
c. The original developer of the K145 (Quozl) has a project
page:
http://james.tooraweenah.com/moin/ts
d. If you're unsure about the usability of your serial port,
you might want to try connecting
with the K145
Tester, or HyperTerminal. If you
can connect, and the data is not corrupted
in the display, then your port should be OK.
If you're not familiar with HyperTerminal,
there's a tutorial here.
e. There is an RS232 tutorial here.
