EADPHONE JACK
The machine display has two jacks for connecting headphones. The two jacks are connected in
parallel to a stereo output of the CPU board. In addition to the audio signals, the connector also
includes a sense signal for routing the output to either the headphones or external speakers, if
the latter are installed. The sense contact is NC and opens when the headphone jack is plugged
in.

OARD
This board makes available a communication port, on 1 externally accessible connector, which can
be used for interfacing compatible CSafe devices such as the CardioTheater readers. This connector
is situated on the back of the display. Another free connector is available on the board.
These connectors can also be interfaced, using a special cable, to an external PC for programming
the FLASH EEPROM.
3.1.3. TGS
READER
This board enables the machine to read and write on the user's TGS key for performing workouts
programmed with the Wellness System.
3.1.4. H
AND SENSOR BOARD
This is the board which manages the hand sensors, interfacing them to the display board. It
processes the analogue signal received from the sensors and outputs one pulse for each heart beat
that is detected. The signal level is normally 5 Vdc; it goes to 0 Vdc when the user’s hands are
placed on the contacts, and a 5 Vdc pulse (having a width of approximately 30 msec) is output at
each detected heart beat.
3.1.5. C
ARDIO RECEIVER
This board manages the signal received from the telemetric transmitter used by the person
exercising. It receives the power supply signal from the display board and outputs a negative logic
pulse for every heart beat that is detected: the signal level is normally 5 Vdc, with a pulse at 0 Vdc
(having a width of approximately 30 msec) at each heart beat.
The receiver 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 this area, the
receiver becomes saturated and no longer receives any signal.
3.1.6. C
ONNECTORS PANEL
This is located on the side of the front platform, and provides a connector for the antenna cable (on
700iE model only).
3.1.7. 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.
