ARB Compressor Connect App can be used to control and monitor ARB Compressors that are equipped with the ARB Compressor Connect Module. The ARB Compressor Connect Module is included in two kits, the Pressure Control kit used for tyre inflation and the Air Suspension Control kit for use with air bag suspension. When used with the Pressure Control kit, 3 distinct modes allow complete control of the air outlet: - Pressure Control mode allows you to Inflate/deflate tyres and other attached accessories to the pressure of your choice - Pressure Max mode opens the valve, supplying full air pressure at the outlet, allowing the use of an air blow gun - Pressure Off mode closes the valve, hence no air pressure at the outlet - Monitor the Current Pressure of the tyre being inflated/deflated - Select the Target Pressure for Pressure Control mode from the presets, or manually adjust the target pressure - Monitor the vehicle voltage When used with the Air Suspension Control kit you can manually adjust the set pressure by tapping on it - Adjust Suspension Now makes the Air Suspension Control check the pressure and adjust it if required - Select from 4 user definable pressure presets - Monitor the vehicle voltage Through the Apps settings screen you can: - Program up to 4 nameable pressure presets - Set the Minimum System Pressure. For Air suspension this the minimum set pressure required by the air bags - Set the Maximum System Pressure. For Pressure Control this is typically, 500kPa (70PSI), which is based on the lower limit of your compressors pressure switch. For Air Suspension Control this is the maximum set pressure required by the air bags - Set pressure display units (kPa, PSI, bar) - Set the Power On Mode. This determines which mode the ARB Compressor Connect module starts in when the compressor power is turned on. For example, if you set it to ‘Off’ then it will start in ‘Pressure Off’ mode and no air pressure will available at the outlet However if you set it to ‘Max’ then it will start in ‘Pressure Max’ mode and full air pressure will be supplied at the outlet - Set Allow Only If Engine Running mode. This prevents the ARB Compressor Connect from activating the compressor when the vehicles engine isn’t running. This is based on the voltage reading - Disable System (deflate to zero). This completely deflates the airbags and disables adjustment so they can be removed / serviced - Recalibrate Pressure Sensor if the zero reading isn’t accurate - Forget Wireless Connection. Disconnects and forgets the wireless connection with the ARB Compressor Connect Module. The App will restart to allow for a new wireless connection.

Take your vehicle’s setup to the next level with the Diode Dynamics D-Switch. This advanced 8-channel switch panel gives you full, customized control over any 12V accessory that you want to wire up. And as you might have guessed, our engineers have also tailored it specifically to be the most functional and effective controller when it comes to your lighting setup. The D-Switch features four 30A outputs and four 15A outputs, putting it solidly into the "serious" category for total power delivery, but it’s packed with all kinds of other features to customize your setup! While there are many 8-button controllers on the market, the D-Switch stands apart with a 9th button dedicated to the backlight bus bar. The backlight bus provides eight extra outputs for your accent lights, allowing you to connect all of your backlit accessories without using up any of your main outputs. With just the press of a button, you can now activate all of your backlights at once! This is a game-changer for any rig with multiple lights installed. It’s also designed to give you complete control over your vehicle’s setup with eight customizable output channels. Unlike traditional switch panels that are one-to-one, meaning Channel 1 is always tied to Button 1, the D-Switch allows you to group and configure multiple output channels per button, allowing you to control multiple outputs with a single button. You can also power a single output with the different strobing patterns that are included. For example, you can program one button to strobe a light and another to run that same light at full power. Whether you're running Diode Dynamics off-road lighting or any other 12V accessories, the D-Switch allows you to customize each button to do exactly what you need. To activate and use the D-Switch, you can use the included controller, or control it using your phone with this app! Say goodbye to switch panel apps that lag, freeze, or don’t connect. The D-Switch Bluetooth app delivers instant response and easy programming with no loading screens or connection delays for a seamless and fast experience, every time. The D-Switch includes four trigger wires, along with a dedicated Ignition wire for added flexibility. This allows you to control your whole setup using vehicle signals, for a completely integrated experience. The ignition wire can be wired into an OEM ignition source and will activate the D-Switch when the ignition is turned on. It will also shut things down when the ignition is turned off. No need to manually turn your panel off! If you want to use any outputs without the ignition turned on, no worries - you can still turn the controller on manually at any time. The three trigger wires provide seamless integration with any of your vehicle’s 12V factory signals, such as high beams, fog lights, or reverse lights. This allows you to activate your outputs automatically–no buttons or switches. With some simple programming, your entire setup can operate like it’s fully integrated on your vehicle. Lastly, the Night Mode wire can be used to activate certain outputs, such as dimming outputs, or adjusting settings for low-light conditions. This trigger also adjusts the brightness of the controller’s backlighting automatically when driving at night. Built for extreme durability, the D-Switch features a solid-state design with no mechanical relays to wear out, or physical fuses to replace. The hub is encapsulated with an aluminum heatsink, ensuring superior heat dissipation. The D-Switch is IP67-rated for weather resistance and is backed by a 3-year limited warranty, ensuring long-term reliability and performance. Whether you're off-roading or on the road, it’s built to withstand whatever you throw at it.
