In addition, you can use Polar IR Interfaces or other manufacturers' IrDA supported IR interfaces. A computer's internal infrared port can also be used. With Polar S610, Polar S710 and Polar S810 data transmission is enabled through Polar IR Interfaces only.Action data from Polar AXN500 and Polar AXN700 can NOT be transferred using this device. They require a IrDA compatible infrared interfaces, for example, a computer's internal infrared port. The New USB 2.0 IrDA is compatible. UpLink
