Software is needed for logging and viewing data from the timer.


The timer data log is a CSV (Comma separated value) data stream.
It's sent through the serial port at 9600 baud (default) or 57600 baud.


Each line of data is terminated with a carriage return and line feed.

When data logging is turned on there will be a short delay
before data is output. This gives you time to turn on logging 
on your capture program before log data is output.

When logging is turned on, a header line is sent with the following
column names:

Rate, Rate Avg, Beat E, Temp.

Rate: The current clock rate.
Rate Avg.: The average clock rate.
Beat E: The current beat error.
Temp: The current temperature.

Temperature data is still logged even if the temperature display is off.
Temperature data will be invalid if a temperature sensor is not attached.


After the header, data values are sent until logging is turned off.

You'll need a program to capture the serial data to a file and then
display the data on your PC.

A serial terminal emulator program is needed to communicate with the timer
through the serial port and to capture the data to a file.

Many terminal emulators are available. Most operating systems include one.
Microsoft windows has Hyperterminal.

Any terminal emulator that can capture RS-232 serial data to a file will work.

I use Tera Term with my timer.

You'll also need software to graph and display the data.

Many programs are available.

I use KST and TimeLab.
