Console Sub-Systems

The console is responsible for interactions with the following 5 sub-systems:
• Treadmill Operation: The functions and components that the user interacts with while working out on the tread-
mill. Includes:
- Main Keypad (Display Panel)
- Display Electronics
- Data Cable
• +11 volts input supplied by MCB/LCB
• Microprocessors for display software
• All calculations processed from display software (speed/ distance/ calories/ heart
rate features/ incline percentage/ users program control/ etc.)
• Communicates RPMs in PWM format when commanding the MCB to generate
speed
• Processes speed to MPH calibration and store the values
• Retrieves the speed sensor signal from the MCB (sensor feedback for speed calcu-
lation)
• Output voltage to heart rate control board
• Output C-Safe voltage for Cardio Theater, Broadcast Vision, Fitlinx, etc.
• Input signal for uploading display software
• Stores maintenance mode parameters
• Stores manager mode settings
• Wiring from HR contact board on Fit CPU to HR grip plates
• HR contact board & wireless HR Polar board
• Process MCB commands for Fit CPU
• Analog to digital converter
• Elevation controller
• Converts serial communication to PWM signal
• Process RPM from MCB so Fit CPU can measure speed
• Microprocessor for Fit CPU software
• Link between converter board and Fit CPU
• All calculations determined from display software (speed/ distance/ calories/ heart
rate features/ incline percentage/ users program control/ scales functions/ etc.)
• Processes speed to MPH calibration and store the values
• Retrieves the speed sensor signal from the Translator board (sensor feedback for
speed calculation)
• Input Heart Rate Signal for contact board and, or wireless Polar signal
• Input signal for uploading Fit CPU software
• Fan controller and power
• Emergency stop controller
• HDMI and USB link to computer interface
• Provides power to USB port
• Process RPM from MCB so Fit CPU can measure speed
• Detects all key strokes
• Audio output connections
• Fan keypad signal control
• Link with FitCPU and CCB
• PC Interface board to Main PCB to control the 2 fans
• Bluetooth to Main PCB
• Interface through PC Interface Board to CPU
• Individually replaceable
