Heart Rate Monitor Communications/Software

If data transmission via serial port fails

Checking the computer's (BIOS) settings and operating system settings

If data transmission from the heart rate monitor fails, then the fault may be caused of the computer settings and/or the operating system settings. If you are not familiar with these settings, please contact a specialist or your local computer dealer for assistance. The settings are hardware system specific and operating system specific, which means that Polar cannot, unfortunately, provide you with universal instructions in this matter.

However, the first advisable step to take is to ensure that the hardware i.e. the HR monitor and the Interface is functioning without any problems. Use another computer for this purpose if possible.

Default settings for serial ports

Each serial port (in addition to the internal mode) has its own Base I/O Address, which cannot and must not be identical to that of any other device, and an interrupt line (IRQ Line) that can be shared by two serial ports. Serial ports COM 1 and COM 3 are generally connected as a pair to interrupt line IRQ 4. Similarly, serial ports COM 2 and COM 4 are connected to interrupt line IRQ 3.

The same interrupt line can be shared with Polar interface units and the modem. This means that the interface unit and the modem will function independently but not at the same time. This is why no devices can be connected to a port that is paired with the mouse.

The most common address/interrupt line pairs are as follows:

Port Interrupt line Base address
COM 1 IRQ 4 03F8h
COM 2 IRQ 3 02F8h
COM 3 IRQ 4 03E8h
COM 4 IRQ 3 02E8h

These serial port settings are found in the computer's BIOS settings and in the Windows Control Panel settings. For the serial ports to function properly, these settings must be compatible.
