Cardio Transmitter; Rj45-Rs232 Board; Power Supply; Alternator Interface Board - Technogym Top 600 XTPRO Service Maintenance Manual

• Non-coded: this is the standard product.
• Coded: this is the product which, utilizing Personal Coded Device technology, receives the
heart rate together with a code that identifies the transmitter in question. In this way the
machine can identify the source of the heart rate signal, thereby avoiding interference problems.
Its reception area is approximately a circle of 1 meter of radius. If there is electromagnetic noise
(produced by high voltage lines, radio transmitters, monitors, motors, etc.) within its reception area,
the receiver becomes saturated and stops receiving any signal. If it is non-coded and there are 2
transmitters within its area of reception, it will receive signals from both, and may produce an error
or irregular reading.
CPU BOARD
This is the heart of the machine, which controls all the machine functions by executing the program
stored in EPROM. It receives information from the user (age, weight, etc.) during set-up of the
training session, from the cardio receiver and/or the HS interface board (user's heart rate) and from
the alternator interface board for displaying workload data (Watt and RPM). It controls the
difficulty level selected with the "+" "−" keys or according to the chosen training program.
3.1.2. C
ARDIO TRANSMITTER
It is worn by the person using the machine, and transmits to the cardio receiver one pulse for every
heart beat that is detected. There are 2 types of transmitter:
• Non-coded: this is the standard product;
• Coded: this is the product which, utilizing Personal Coded Device technology, transmits the
heart rate together with a code that identifies the transmitter in question. In this way, the coded
receiver on the machine can identify the source of the heart rate signal, thereby avoiding
interference problems.
3.1.3. RJ45-RS232
This circuit board provides the machine connections to external devices:
• 1 serial port for connecting to the TGS reader;
• 1 serial port, currently not used, for future connections;
• 1 RJ45 port for the power supply to the portable Cardio Theater unit.
3.1.4. P
OWER SUPPLY
Receives the mains voltage at its input and outputs the DC voltages (+5 Vdc, +12 Vdc and −12
Vdc) which supply the display and the alternator interface board.
The machine uses only +5 Vdc and +12 Vdc.
3.1.5. A
LTERNATOR INTERFACE BOARD
Receives from the display a square-wave signal whose frequency is proportional to the selected
level of difficulty, and converts it into a DC excitation voltage for the alternator. Receives the RPM
signal from the alternator, which it filters and sends to the display for calculating the speed.
