Direction input (B) The direction signal determines if the counter will be
incremented (direction = "0"), or decremented (direction = "1") on each rising
edge of the counter input.
Reset The reset signal will reset the counter to zero. The reset enabling as well
as the active level is determined under software control.
The actual mode of the counter/timer channel is selected in the Perception
software.
The most common type of incremental encoder uses two output channels (A
and B) to sense position. Using two code tracks with sectors positioned 90
degrees out of phase, the two output channels of the quadrature encoder
indicate both position and direction of rotation. If A leads B, for example, the
disk is rotating in a clockwise direction. If B leads A, then the disk is rotating in
a counter-clockwise direction.
By monitoring both the number of pulses and the relative phase of signals A
and B, you can track both the position and direction of rotation.
Some quadrature encoders also include a third output channel, called a zero
or index or reference signal, which supplies a single pulse per revolution. This
single pulse is used for precise determination of a reference position.

The binary marker HV modules come with nine (9) fiber optic connectors (see
Figure 12.29) and two (2) 26-pin connectors. The lowest fiber optic connector
provides the recording status output. The fiber optic input connectors provide
the marker (event) channels 1 through 8. The non-isolated marker inputs
provide the marker (event) channels labeled 33 through 64.
