Electrical Basics of Digital Switching

Positive Switched and Dimmed Circuits If you are in your forties or older, you probably have had poor experiences with wireless. Positive polarity switching is the most common form of digital switching. The output from the con- troller to the wired device becomes a positive 12Volts when turned on and zero voltage when turned off. The other wire from the device is connected to battery negative. Best practice is to also always have all negatives to a common chassis ground. If you have wired this way then only one positive wire goes to the device and the other wire goes to chassis ground. NEVER connect his “other wire” back to a STAR controller. Dimming positive circuits simply reduces the effective voltage at the LED which dims the LED. Negative Switched and Dimmed Circuits Negative polarity switching is common with high quality dimmable LED’s, particularly LED strips or rolls. The output from the controller to the wired device Connects the LED to zero volt battery negative or ground when turned on. The other wire from the device is connected to battery 12V positive and must be fused independently. NEVER connect his “other positive wire” back to a STAR controller. Dimming negative circuits simply increases the effective voltage at the LED on the negative side reducing the difference between the 12V positive and the negative voltage which dims the LED. A potential problem with lots of negatively dimmed LEDs is that the ground becomes "noisy" due to switching—can interfere with other electronics. STAR-Switch Custom Circuits Up to 6 inputs from third party switches or other devices can be wired into this device. Each input is configured as: 1. 12V positive (or high) input generally turning on an LED when activated on the independent switch itself. In this case the input is called positive high. The input can be a latched switch or ignition wire or similar or a momentary input from a push button. The input is configured as “latched or Momentary” 2. Wire input that is switched to Zero voltage or ground. Typically these inputs are door switches or alarm switch inputs as no fusing of the wire is needed. The input can be a latched switch or ignition wire or similar or a momentary input from a push button. The input is configured as “latched or Momentary” Logic blocks can then applied to these inputs as described later in this manual. Always use CAN communication from these switches to the STAR controllers when using logic and safety cicuits. Using Gas Strut Switches for Automatic canopy Door Opening On/Off Generally use positively switched and dimmed LED lights and wire the negative return wire through the gas strut switch.
