Logic Equation Configuration of Variables

Use these questions to configure the internal variables used within logic equations.

To access these questions, in the RCP> prompt, type: Control Variables

Choose: Retrig Single Filter Retard Extend Clock

Timer #0 trigger mode: Retrig

Timer #0 period/delay: 1.0

There is a question in this form for each of the available timers. Choose the mode of each timer (See Logic Equation Timer Variables), and its associated period or delay (in seconds).

Minimum velocity for 'antstop': 0.50 deg/sec

Minimum time for 'antstop': 2.00 sec

The status variable antstop is set to:

• TRUE when the antenna seems to be stopped, that is, has been moving slower than a prescribed speed for more than a prescribed time.

  These setup questions configure the speed and time thresholds.

  Both the AZ and EL axes must appear to be stopped in order for antstop to be TRUE.

• FALSE when the antenna seems to be moving, that is, the speed on either axis has exceeded the threshold speed for more than the specified time.
