there will be a 128 second delay before
compiling and running the program. This can
be used to edit or change the program before it
starts running. To raise the ring line, press any
key on the CR10KD keyboard display or call the
CR510 with the computer during the power up
sequence (i.e., while “HELLO” is displayed on
the CR10KD).
In order to ensure that there is no active
program in the CR510, we will load an empty
program using the *D Mode:

In this example the CR510 is programmed to
read its own internal temperature (using a built
in thermistor) every 5 seconds and to send the
results to Final Storage.

The CR510 is now programmed to read the internal
temperature every 5 seconds and place the reading
in Input Storage Location 1. The program can be
compiled and the temperature displayed.
