Product Description

Tm200 1HOSAND® GT.a comprises: the transmitter, worn by the subject along with a standard cardio chest strap which measures the heart rate; the receiver; the synchronisation box and the software.
The transmitter intercepts the heart rate picked up by the chest strap and sends the data in real time to the receiver;  they are then conveyed via the synchronisation box to the computer,  where they are processed, organised and efficiently displayed by the software.
A revolutionary system able to monitor individual heart rates of up to 32 people simultaneously.  This means that each individual's effort during a workout can be assessed "live", so that immediate adjustments can be made on the intensity of the person's effort.
HOSAND® is an indispensable work tool for coaches, physical education teachers, fitness trainers and anyone who requires to monitor the heart rate of one or more people simultaneously, with great precision and without delay.

Technical Data

Tm200 2 

HOSAND® Transmitter
The transmitter, attached to a standard cardio chest strap, is powered by a 3V Lithium CR2032 battery.  It intercepts the 5kHz radio signal emitted by the chest strap of a standard heart rate monitor (not included) worn by the subject, memorises the data in an internal Flash memory, re-processing them to the sole purpose of improving their transmission, and then transmits them via radio at a frequency of 433.92 MHz.
The lower and upper heart rate alarm limits preset during synchronisation are continuously checked against the current rate; if these limits are exceeded,  a warning beep will sound.
The radio module receiving the signal at 5 kHz and the standard module transmitting at 433.92 MHz are integrated by HOSAND Srl with the other electronic components on a printed circuit.
The transmitter can be attached to the cardio chest strap by a Velcro strip  or inserted into a special pouch worn round the neck or sewn into a special vest worn by the subject, depending on the type of activity to be monitored. The indicative maximum distance between the strap and the transmitter shall not exceed 30 cm.

HOSAND® receiver with antenna
Receives the signal emitted by the transmitter, transferring it via cable to the Software installed on the PC (or other device).  The receiver is connected to the PC via the Synchronization box cable, which also provides the power supply. The radio receiver module is a standard type.
HOSAND® receiver with antenna Technical Data:
• Connection to PC (via synchronisation box): USB port
• Interference elimination algorhythm: integrated
• Potential reach: other receiving antennae can be connected to increase telemetric reach
• Power supply: via USB port
• Casing material: ABS polymer

HOSAND® Synchronisation box
Mounted on the cable connecting the receiver by a 3-pin connector at one end and the PC on the other, via the USB port.  Activates the transmitters (to a maximum of 32) and detects the signals arriving from them; data can be downloaded at a later time.

HOSAND® Synchronisation box technical data:
• Use:
      • connects the receiving antenna to the PC
      • switches on, synchronises and switches off the transmitter
      • downloads the data fed by the transmitter
• Power supply: via USB port
• Casing material: ABS polymer


HOSAND® Software
The software module displays the following information in real time (telemetry):
• Instant, minimum, maximum, and average heart rate received
• Progressive graphic flow of values, with the option of inserting "markers" to identify specific activity periods
• Bar graphs for frequency classes
• Up to 5 target zones for each subject, labeled in five different colors
• Pie-charts for each target zone
• According to physiological parameters preset for the subject and the heart rate values received:
• caloric consumption (theoretical)
• oxygen consumption (theoretical)
• Simultaneous bar-graph values relating to all subjects
• 3D surface-graph of values relating to all subjects
Further data processing available from the software (after conclusion of the telemetric mode) are:
• Opening and closing the list of recordings
• Editing the recordings
• Ordering the list of recordings 
• Simultaneous opening of additional curves
• Basic graphic display
• Graphic display of heart rate
• Statistical functions
• Information on minimum, average and maximum values
• Filter functions
• Enlargement functions
• Cutting functions
• Notes function (internal clipboard)
• Copy and paste functions
• Linear regression
• Events marking
• Insertion of texts
• Bezier function
• Printing function
• Replay
