Applying negative voltage may destroy the GPIO!
Beware not to inadvertently toggle the GPIO from Input to Output Mode: you
may create a short circuit when using a high current source to ground as an
input device! Refer to Figure 5.20.
5.5.3.6 People Counter
Figure 5.21: People Counter
The “People Counter” section displays the total number of people that crossed the IR sensor:
 Whatever the direction (In & Out) if no bidirectional IR sensor is installed.
 In each direction (In & Out) if bidirectional IR sensor is installed.
People counter value is battery backed-up, and is consequently restored at
power-up.
Click on “Clear Counter” button to reset people counter.
To reset people counter, you can also use a pointed element (for example, a
paper clip), insert it in the hole on the left of the display window and press
(not too strong) until zero is displayed.
Use the drop-list in the “People Counter” section to select which count is to be displayed on
pedestal LCD:
 “Display In” to display In counter only
 “Display Out” to display out counter only.
 “Display In + Display Out” to display the sum of In and Out counters.
Pedestal must be rebooted for changes to take effect.
The drop-list is not available if no bidirectional IR sensor is installed. In this
case, pedestal LCD always displays the sum of In and Out counters.
