RECIEVER
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 with a 90 cm 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.
The Salutron 8500 models, manage both the telemetric transmitter and the hand sensors signals, in
the same way.
On the receiver it is present a jumper (
JP1
) which allows to set the heart rate data acquisition
priority as follow:
JP1
CLOSED
= Chest strap priority
JP1
OPEN
= Hand Sensor priority
The standard configuration of the receiver is with chest strap priority.

These joysticks in fact send the display board the same signals produced by pressing the “+” and “-
