Clock controlled by input A
This is the simple mode where the starting and stopping of the stop clock is controlled by one
device. Anything plugged into socket B is ignored. In this mode, there is a debounce delay of
12 centi-seconds.
Clock Controlled by Inputs A and B
This mode is a little more complicated, as input from two devices is used to control the timer.
In this mode, the stop clock only responds to blocking of light gates (i.e. falling edges).
For example, a vehicle passes through one light gate, and then through another. The stopclock
will start timing as soon as the vehicle blocks the first light gate, and stop timing as soon as
the vehicle blocks the second light gate.
