Csafe Board; Tgs/Smart Card Board; Hand Sensor Board; Cardio Receiver - Technogym RECLINE EXCITE Service Maintenance Manual

3.1.2. CS B
AFE 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.
3.1.3. TGS/S
MART
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. H
AND SENSOR BOARD
This is the board which manages the hand sensors, interfacing them to the Digital Plan Board. It
processes the analog 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. There are 2 types of receiver:
• HFU Model (on 500 models): this is the standard product. 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.
• OwnZone Model (on 700 and 700E models): this is a special receiver model produced by
Polar, equipped with a 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:
>
a pulse signal: a pulse for every heart beat that is detected;
>
a reset signal: an external reset signal provided by the digital plan board every times an
exercise is started;
>
a serial signal on a I2C protocol.
The receivers 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.
On the 700SP models a reset cable between the OwnZone receiver and the Digital Plan
has been added in order to avoid that the receiver overwrites some configuration data
when the machine turns on.
