In the Coach software all CLAB inputs can be (simultaneously) used as counter
inputs. Sensors such as the CMA Photogate or CMA Radiation sensor are by
default defined as counters. Other analog sensors can be used as counters (e.g.
using a Heartrate sensor as a counter) after defining the
counter conversion
settings.
