PCB POWER CONNECTIONS

A +24V DC, 65W class 2 power supply unit is connected to the PCB through CON1. The necessary connections have

already been made on the boxed variants (see Figure 3), so there is no need for the installer to make any further power

connections to the PCB. On PCB versions, connect the +24V DC as shown below.

CONNECTING THE PRESET FEEDBACK POTENTIOMETERS

If you are using a preset Pan/Tilt head and lens, then CON2 provides the supplies and feedback connections for the

potentiometer wiper circuits. The direction of the DC feedback circuit is automatically calculated when the test routine is

invoked (see Testing on page 18). This means it is not necessary to wire the pots in a specific direction.

Referring to Figure 4, connect CON2 to the preset pots on the Pan/Tilt head and the lens. Connect any unused feedback

inputs to ground. Make a note on your module description sheet of the preset connections and the type of lens.
