5 Connecting To a PC
5.1 What software is available
5.1.1 HomeSeer
HomeSeer is perhaps the most popular method of interfacing to TEMP08.
HomeSeer is available at www.homeseer.com and interface scripts and plug-ins
are available on the HomeSeer Forum. Midon Design also provides a simple
script interface on our website.
Jim Doolittle, Ken Mitchell and Michael McSharry have written HomeSeer plug-
ins for TEMP08. These are available from the Forum or direct from the authors.
5.1.2 DooTemp08
DooTemp08 was a stand-alone software program that was also useable as a
HomeSeer plug-in. It is no longer supported following the loss of the author.
5.1.3 Thermd
Thermd is a free software program developed by David Klein that can also
interface to TEMP08. It is available at http://www.klein.com/thermd. This
software is written in Perl and the source code is provided on David’s website.
5.1.4 Roll your own
You can, of course, always write your own software to interface to TEMP08.
What you need is software to read and write to a serial port on your PC and to
interpret the returned results. All TEMP08 commands are documented in the
User Manual. Output examples are also provided there.
5.2 Physical connections to a PC
A straight-through, not null modem, serial cable connects between the TEMP08
and your PC's serial port. Straight-through simply means that all pins of the
connectors on each end are the same, pin 1 of one connector is cabled to pin 1
of the second connector, pin2 to pin 2, etc. One connectors needs to be a DB-9
Male connector to fit the TEMP08, and the other connector needs to be a DB-9
Female connector to fit the PC. In case you want to make your own cable,
TEMP08 only uses the TX (pin 2), RX (pin 3) and Ground (pin 5) pins of an
RS232 cable to communicate.
