7. Installation
7.1. Positioning and scanning distance
The topCam6500 is fitted at a distance of 80mm (SD version) from the surface. In case of
reflecting surfaces (e. g. labels) the topCam6500 should be mounted in an inclined position, as
shown in Figure 1, in order to eliminate direct reflections.

8. Electrical connection
8.1.
Power supply
The topCam6500 is supplied with a direct voltage of 18 volts to 24 volts. The supply voltage
is impressed between pin 5 (+10..24 volts) and pin 1 (GND). The topCam6500 is protected
against incorrect polarity of the supply voltage.
8.2.
In and outputs
The optically insulated in and outputs of the topCam6500 have their own supply connections.
The outputs receive their supply voltage of 18-24 volts from pin 11 of the HD-15 connector.
The output signals are PNP signals.
Reference position for the inputs is pin 15 of the HD-15 connector.
The outputs are short-circuit proof. They switch off automatically in case of overload. In
order to reactivate the outputs after such an overload turnoff, switch the supply voltage at the
outputs off and on.
Output 1 (pin 12 of the HD-15 connector) is activated when a code has been scanned
correctly.
Output 2 (pin 13 of the HD-15 connector) shows a scanning error. Polarity and duration of
activation of the outputs are configurable.
Input 1 (pin 14 of the HD-15 connector) serves as a trigger input. The polarity of the trigger
signal is configurable.
Input 2 resets the statistical counters if a voltage is applied on the input for approximately 3
seconds.
If the trigger delay is to be realized by means of an incremental encoder the signal of the
incremental encoder is to be applied on input 2.
