Figure 2. System Block Diagram
B. Switch Module
The Switch Module harness plugs into the Console and contains connectors for
both keyboard and PC interface as described above.
The operator controls the real-time functions of the Control Point ™ system
from the seven switches on the Switch Module. (See Figure 3).
C. Keyboard
The keyboard is the means the operator uses to program and calibrate the
system. The 86-key, alphanumeric, PC-compatible keyboard has been environ-
mentally hardened for use in the ice-control field. After programming and
calibration are finished, the keyboard is usually disconnected and stored.
D. Ground Speed Sensor
The ground speed sensor generates vehicle speed information for the console.
Sensor electrical pulses proportional to the vehicle ground speed are vital to
system operation because true vehicle ground speed is necessary for accurate
product application. The system can function with a wide variety of electronic
and mechanical speedometer sensors, including Hall-Effect and Reluctance
sensors.
