OARD
This board makes available a communication port, on 2 externally accessible connectors, which can
be used for connecting compatible CSafe devices such as the CardioTheater readers. These
connectors are situated one on the back of the display and the other on the connectors panel
underneath the front platform.
These connectors can also be interfaced, by means of a special cable, to an external PC for
programming the FLASH EEPROM.

OARD
This board enables the machine to read the TGS key or Smart Card inserted by the user for doing
workouts programmed with the Wellness System. The machine can be interfaced with either a TGS
key or Smart Card reader, hence its name TGS/Smart Card Board.
3.1.4. C
ARDIO RECEIVER
This board manages the signal received from the telemetric transmitter used by the person
exercising, and interfaces it with the Digital Plan Board. The machine uses an OwnZone receiver.
This is a special receiver model produced by Polar, equipped with microprocessor and capable of
independently detecting the heart rate. It receives the power supply signal from the Digital Plan
board, to which it is connected by:
•
pulse signal outputs one pulse at each detected heart beat;
•
reset signal: external signal received from the digital plan board at the beginning of each
exercise session, to initialize the receiver;
•
serial signal with I2C protocol.
Their reception area is approximately a circle with a 1 m 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 no longer receives any signal. In addition, if there are 2
transmitters within the reception area, it will receive signals from both.
3.1.5. C
ONNECTORS PANEL
This is located on the side of the front platform, and provides:
•
an RJ45 socket for connecting CSafe compatible devices.
3.1.6. B
RAKE BOARD
There are 2 versions of the brake board, one which is used on the mains powered version and the
other on the self-powered version. In either case, the brake board consists of:
•
Power supply section which generates the low voltages used by the machine: +5 Vdc and +12
Vdc. Depending on the machine version, these voltages will be generated either from the 110
VAC or 220 VAC mains supply, or from the alternator-battery.
•
Section for RS-485 serial communications with the Digital Plan Board for:
-
commands determining the resistance that is required of the brake;
-
brake error messages;
